[android-developers] Progress monitor graphic broken with ICS
Hi, I am wondering if anybody else is seeing this and knows what it is. I use a progress monitor that with ICS now looks like this: [image: Screen shot 2011-12-16 at 4.22.18 PM.png] This is the relevant code: ProgressBar android:id=@+id/background_progress style=?android:attr/progressBarStyleSmall android:layout_width=wrap_content android:layout_height=fill_parent * * *android:paddingRight=17dp* * android:paddingLeft=18dp* ** *android:paddingTop=14dp* *android:paddingBottom=14dp* * * android:background=@drawable/title_button ##* happens with and without the following line* android:indeterminateDrawable=@drawable/progress_small_white android:focusable=true android:clickable=true android:indeterminate=true android:visibility=visible / I ran it on the emulator after Nexus Galaxy users reported the issue. Is this my code that is broken or ICS? Shouldn't dp solve this? It works with ldpi, mdpi and hdpi with releases before ICS.

[android-developers] App Broken After Android Refactoring Rename Application Package / android.view.InflateException
I want to create a new version of my app that caters to the needs of users
with Android 1.5/1.6/2.0 devices and move ahead with the normal version of
my app. For that I copied my app directory then applied the Rename
Application Package refactoring. That helped a lot. So far I mostly had to
fix references to styles.
Unfortunately I cannot launch the app. I get the following stacktrace:
java.lang.RuntimeException: Unable to start activity

The little sense I can make of this tells me that it may have two causes.
(a) The source of the issue is in line #31.
(b) There is an issue accessing res/drawable/label_background.xml.
Here are excerpts of the layout xml that I think is causing the issue:
?xml version=1.0 encoding=utf-8?
[..]
LinearLayout
android:id=@+id/status_bar
android:layout_width=fill_parent
android:layout_height=wrap_content
android:orientation=vertical
* android:background=@drawable/label_background --- Line #21*
android:visibility=gone
LinearLayout
android:id=@+id/label
android:layout_width=fill_parent
android:layout_height=wrap_content
android:orientation=horizontal
TextView
android:id=@+id/control_panel_title
android:layout_width=fill_parent
android:layout_height=fill_parent
[..]
*android:textColor=?lightTextColor / --- Line #31*
ProgressBar
android:id=@+id/progress_status_bar
style=?android:attr/progressBarStyleSmall
android:layout_width=wrap_content
android:layout_height=wrap_content
android:layout_margin=3dp
android:visibility=invisible /
/LinearLayout
/LinearLayout
[..]
When I comment out Line #21 the error is not raised. That would be cause (b)
then I suppose.
I do have a file however that is called
app/res/drawable/label_background.xml:
?xml version=1.0 encoding=utf-8?

[android-developers] Q: How to do an expand animation?
Hi, please consider the following. I have two containers and in between them I want to expand/grow a third container that should show some temporary information. The undo message in the Gmail app is an example for that. It expands between the status bar and the body of the list, thereby pushing the list down. How would you implement that? I place the third/new container in my layout. Then I need to make it visible before I start the animation, because otherwise I wouldn't see it. However then in the parent there will be a gap for the third component right away and the gap will have the full size (the calculated/measured size) right away. Hence when I then start the animation to scaleY from 0.0 to 1.0 I first see the complete space of the underlying container and then slowly the actual component appears ;( What I want is that space growing with the animation. Any ideas? Do I need to set the height to 0 first and then measure myself to define the goal height/Y of the animation as well as to set the component's height myself after the animation is done? Do you know a code sample that does that? Cheers, Mariano -- You received this message because you are subscribed to the Google Groups Android Developers group.

I suspect it is something about the coordination of redraw/invalidation
events, but I don't know where to look exactly.
When I update the model (the sqlitedatabase) I run the following code on the
UI thread afterwards:
void refreshUI() {
((BaseAdapter) getListAdapter()).notifyDataSetChanged();
// the remaining calls are just included for completeness
// they update different ui elements, but don't access the cursor in
any way.
updateButtons();
updateControlPanelTitle();
updateProgressBar();
}
Any other information I can provide?
Cheers,
Mariano

Re: [android-developers] How to debug CursorIndexOutOfBoundsException with ListView?
Any idea how I can get to the bottom of this?
I am wondering if this error message means that the list view ask for the
number of rows in the list adapter, but during the rendering of the list
this number changes (is reduced). That code is not in my hand though.
How would I deal with that?
Currently I change the database on a background thread, send a notification
(notification in the generic sense, not an Android notification) afterwards
and the listeners that want to change the UI (like refreshUI() form below)
use runOnUiThread() to process the event.

Re: [android-developers] How to debug CursorIndexOutOfBoundsException with ListView?
Hi Rajesh,
when there is no data in the model then the empty view is shown, which I
think is correct.
Also I don't think I do any of the things you mentioned.
The only thing where I don't have a good feeling about is the following
method, that is run on the UI thread. It is called when the model is
updated, which may include a change to the query criteria:
private void updateCursor() {
if (dbQuery.hasChanged()) {
Timing t = null;
if (NewsRob.isDebuggingEnabled(this))
t = new Timing(ArticleListActivity.updateCursor() change of
cursor, this);
final Cursor oldCursor = listAdapter.getCursor();
if (oldCursor != null) {
stopManagingCursor(oldCursor);
listAdapter.notifyDataSetInvalidated();
oldCursor.close();
}
final Cursor cursor = getEntryManager().getContentCursor(dbQuery
);
startManagingCursor(cursor);
listAdapter.changeCursor(cursor);
if (t != null)
t.stop();
// listAdapter.notifyDataSetChanged();
} else {
Timing t = null;
if (NewsRob.isDebuggingEnabled(this))
t = new Timing(ArticleListActivity.updateCursor() requery,
this);
// listAdapter.notifyDataSetChanged(); doesn't work. use requery
// instead
listAdapter.getCursor().requery();
if (t != null)
t.stop();
}
}
But with the limited knowledge I have about the current issue, this code
doesn't seem like the culprit.But if you have a good idea about it, I am
very willing to listen.
?

Re: [android-developers] Re: On using themes?!
As it wasn't possible to submit a new post to the existing/old conversation
using the web interface I am copying the message here with Danilo's
permission:
Hi Mariano.
Did you manage to work using themes from drawables xml?
I have same problem and there is no any reference but this thread and
there is no solution here.
If you find solution please let me know.
I currently solved it by using different drawable xml for every
theme but as you can see this isn't a god solution at all.
About your question about getting a color from a theme (I know its old
but for future readers :) ) solution I created is like this:
private static int getColor(final Context context, final int id,
final int defaultColor) {
try {
final Theme theme = context.getTheme();
if (theme == null) {
return defaultColor;
}
TypedValue typedValue = new TypedValue();
if (theme.resolveAttribute(id, typedValue, false)) {
final Resources resources =
context.getResources();
final int resourceId = typedValue.resourceId;
if (typedValue.type ==
TypedValue.TYPE_INT_COLOR_RGB8 ||
typedValue.type == TypedValue.TYPE_INT_COLOR_RGB4 || typedValue.type
== TypedValue.TYPE_INT_COLOR_ARGB4
|| typedValue.type ==
TypedValue.TYPE_INT_COLOR_ARGB8 ||
typedValue.type == TypedValue.TYPE_FIRST_COLOR_INT) {
return typedValue.data;
} else {
return
resources.getColor(resourceId);
}
}
return defaultColor;
} catch (NotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
return defaultColor;
}
}

This happens when using it the way we described here in a drawable xml.
However to better understand the error I used it on other attributes and
when using it on the background attribute of a View it works. Maybe this
approach is incompatible with drawables that are expressed in xml?
Btw. Is there any way to get the actual #rgb string for a color from a
theme?

On Tue, May 11, 2010 at 8:02 AM, Dianne Hackborn hack...@android.comwrote:
You need to define an attribute for your value:
attr name=myColor format=color /
Then make a custom theme that supplies a value for it:
style name=MyTheme parent=android:Theme
item name=com.my.package:myColor#ff808080/item
/style
And now you can reference that value from other XML:
shape xmlns:android=http://schemas.android.com/apk/res/android
android:shape=rectangle
gradient android:startColor=?com.my.package:myColor
android:endColor=#66FF
android:angle=270 /
/shape
Note that com.my.package is your manifest's package name.
Also I just wrote this by hand so I won't guarantee it is completely
right. :}

Hmmh, also no answer to this question on themes. Maybe the answer cannot
be given with two lines? So let me explain what I would expect step by step
and you stop me were I deviate from the Golden Path? I'll try yes/no
questions.
In the simplest terms I would expect that in every place I can specify a
color in RGB (#) I could also specify a symbolic name instead. This
should work like @color/xyz, but with one more level of indirection that
lets me switch between themes, like dark and light.
Is that possible?
I would expect those themes to be applicable to (a) widgets, (b)
drawables (see the mentioned example) and (c) when I need to style something
myself like HTML. Are (a) - (c) possible?
Furthermore I would expect that I could define style keys

So if I want to have my app listed on an alternative market, because Google doesn't provide all users with access to paid apps, then I cannot use the new mechanism ... unless the alternative market provides a binary compatible lib. Right? Otherwise I would need to disable the check for non-Android Market apps. Maybe that isn't too bad (except of course for the alternative markets), but it would mean that somebody who has the Android Market needs to buy the apps exclusively there and cannot use an alternative market. Of course, I could also make different versions of my app or just shoot me. On Tue, Jul 27, 2010 at 8:11 PM, Shane Isbell shane.isb...@gmail.comwrote: It's addressing a direct need of developers. From my perspective, I wonder what the impact will be for alternative stores, as they can't use the service. The basic equation developers have to take into account is: are losses from pirated sales (through weakly protected apps on alternative stores) greater than sales from those alternative stores generate? I'm still trying to digest this.

Re: [android-developers] ListView - Row Background Animation
IMHO the list view doesn't shuffle the rows around, but the views that form these rows are re-used in order to avoid the repeated inflation of the views. Instead you get a previously setup view and you only do the data binding, i.e. set the actual values from your model in the views's text fields, bitmaps etc.. However it would only re-use a view that previously was scrolled out of the viewable part of the list. So when your transitions are gone before the view is scrolled out, no jumping should occur as the view cannot be seen anymore. This view might be re-used though by the next view (row) that gets scrolled in and when the animation still runs on it then you would still see it. You could reset the animation before re-using the view. That might have the drawback that an item with a slowly fading background is scrolled out while the transition is in progress and then scrolled in again, also while the transition is still in progress, but as you just reset the animation before the re-use you won't see it anymore. Am I making any sense? Maybe, if your views are very simple, you don't need to re-use them anyway and still have a good performance? Before going into more detail it may make sense for you to checkout those convert views. http://developer.android.com/resources/samples/ApiDemos/src/com/example/android/apis/view/List14.html On Fri, Jun 25, 2010 at 5:58 PM, Daniel Lew danle...@gmail.com wrote: Back when I originally wrote my app, I thought I could use some tricks with TransitionDrawable to briefly highlight some rows in a ListView. However, when I actually implemented this (a fading background), the background would jump from item to item randomly. As my knowledge of Android has progressed, I've learned why this no longer works: the ListView uses optimizations and actually shuffles rows around, so the row that I may have originally told to animate ends up placed in a different spot by the time the ListView is visible. My question is whether there's a solution to this problem. I've thought of using a different view type, but that would only work if I can turn *off* the view type for that row at the right time; since I'm using a TransitionDrawable, there's no way for me (right now) to mark once the animation is done. Does anyone have any ideas on how to make a temporary fading background on particular rows in a ListView? -- You received this message because you are subscribed to the Google Groups Android Developers group.

The website I'm targeting needs a valid session, so, between each http call, I need to send the cookie. Httpclient does it well. This is a tv stream application and I have to fetch the channel url, the url has a token parameter and I have to be logged / authenticated / (= have a valid cookie/sessionid) to fetch the channel url. I got the first cookie/sessionid with the first connection to the website. The cookie is valid for a certain amount of time, there is no expires but I don't know if there is any server cron to cleanup the sessions. I assume I have to ping every x secondes to maintain the session valid. Between each http call, the time could be from 1 sec to several minutes, it depends if the user wants to change the watched tv channel. The http call (to fetch the url) is not made by the UI Thread. There are several possibilities to manage the httpclient : - a single httpclient static singleton instance accessed by a custom synchronized getClient() on an helper class = when / how to release the http connection ? How to handle that correctly if the user got a phone call / does not use the application for now (unvalidate during onResume, etc)? - Save the cookie (String serialized into SharedPreferences) and create every time a new httpclient instance (then set the cookie to the new instance) = overhead to get the http connection - other ?

Hi, Mariano
True, this is a Java question, not an Android question. SO it doesn't
r-e-a-l-l-y belong here. But in the interest of speeding you on your
way, I will make a couple observations I hope you will find helpful.
1) no, the NPE does not imply that isMarkAllReadPossibleCache is the
null variable. Rather, it implies that in the course of trying to
execute the get method of isMarkAllReadPossibleCache, the DVM
encountered a null pointer.
2) the NPE occurred during the call to UpdateButtons(), which in turn
took place during the call to the above get() method.
3) to tell in any more detail where it came from, I would need the
rest of your stack trace, which you chose not to show. But now you
have a better idea how to narrow this down by yourself, without
exposing the code to us, I hope.

return isMarkAllReadPossibleCache.get(dbq); !-- NPE is raised

In the last line from above a NPE is thrown. So the instance variable
isMarkAllReadPossibleCache must be null, right? But I don't see where
this
could happen. It's initialized in the constructor and never set to null
afterwards.
For completeness here is a stack trace:

Re: [android-developers] Need help with a Java issue
Hey Toni.
Yes, I verified that this is the exact spot where the NPE occurs. More than
10 times ;) It would be possible though that the tag I used wasn't accurate,
but even then I wouldn't know which of the variables could be null and fail
in that way. The databaseHelper is also initialized in the constructor.
No, I didn't leave out the synchronization, but I think it wouldn't make any
difference as this would only affect if an item is in the Map, not if the
Map is instantiated/null. This should be concluded after the constructor is
left and the object is kicked into life, right?
Just because I am so unsure, I tried to call Map.get as well as Map.put with
null and interestingly enough it works. If I put some Object with a key of
null into the Map I get the same object back when I access the Map again
with null as the key. But that is actually not really relevant here – I
think – as the NPE happens right on the last line and not inside the Map
implementation, which would be the case if the Map would have an issue with
a null.
Thanks for helping me to think here ;)
Cheers,
Mariano

Hi Mariano,
First of all, did you leave out synchronization for simplicity in this
mail or is it not in place at all ?
(assuming you do access EntityManager from multiple threads).
Also, pls doublecheck that EntryManager.java:1529 is really at the
spot you indicated (cannot verify with complete sources).
Specifically i am unsure about databaseHelper. Its just accessed in
you example, so could be null.
At best give the full file so we can check.

[android-developers] Re: Process.setProcessGroup() Unknown error?
Forget it. I think I have the issue. Too many open files. Maybe of interest to others: I frequently saved a preference (current article) in the preferences, but this took ages as a whole XML tree needs to be created and written to flash. To speed things up I changed the implementation to a randome access file where I kept the handle(?) (java.io.File) around. I always closed the file after reading/writing, but never closed the File handle. What's new to me is that this produces lots of open files. I would have expected that this is not the case as I always close the actual RandomAccessFile. I was wrong it seems. To find out about the files you need to know the pid of your app's process and then I ran this: adb -s emulator-5556 shell ls -l /proc/1160/fd Which then produces something like this: lrwx-- root root 2010-06-14 20:09 0 - /dev/null lrwx-- root root 2010-06-14 20:09 1 - /dev/null lrwx-- root root 2010-06-14 20:09 2 - /dev/null l-wx-- root root 2010-06-14 20:09 3 - /dev/log/main l-wx-- root root 2010-06-14 20:09 4 - /dev/log/radio l-wx-- root root 2010-06-14 20:09 5 - /dev/log/events lr-x-- root root 2010-06-14 20:09 6 - /system/framework/core.jar lr-x-- root root 2010-06-14 20:09 7 - /system/framework/ext.jar lr-x-- root root 2010-06-14 20:09 8 - /system/framework/framework.jar lrwx-- root root 2010-06-14 20:09 9 - /dev/ashmem lrwx-- root root 2010-06-14 20:09 10 - socket:[41904] lr-x-- root root 2010-06-14 20:09 11 - /system/framework/android.policy.jar lr-x-- root root 2010-06-14 20:09 12 - /system/framework/services.jar lr-x-- root root 2010-06-14 20:09 13 - /system/framework/framework.jar lr-x-- root root 2010-06-14 20:09 14 - /system/fonts/DroidSans.ttf lr-x-- root root 2010-06-14 20:09 15 - /system/framework/core.jar lr-x-- root root 2010-06-14 20:09 16 - /dev/urandom lr-x-- root root 2010-06-14 20:09 17 - /system/framework/framework-res.apk lr-x-- root root 2010-06-14 20:09 18 - pipe:[41905] l-wx-- root root 2010-06-14 20:09 19 - pipe:[41905] lrwx-- root root 2010-06-14 20:09 20 - socket:[41908] lrwx-- root root 2010-06-14 20:09 21 - /dev/binder lrwx-- root root 2010-06-14 20:09 22 - /dev/ashmem lrwx-- root root 2010-06-14 20:09 23 - /dev/ashmem lr-x-- root root 2010-06-14 20:09 24 - /data/app/com.newsrob.apk lr-x-- root root 2010-06-14 20:09 25 - /data/app/com.newsrob.apk lr-x-- root root 2010-06-14 20:09 26 - /data/app/com.newsrob.apk lrwx-- root root 2010-06-14 20:09 27 - /data/data/com.newsrob/databases/newsrob.db lrwx-- root root 2010-06-14 20:09 28 - /system/fonts/DroidSansFallback.ttf lrwx-- root root 2010-06-14 20:09 29 - /dev/ashmem lrwx-- root root 2010-06-14 20:09 30 - /dev/ashmem lrwx-- root root 2010-06-14 20:10 31 - /dev/ashmem lrwx-- root root 2010-06-14 20:09 33 - /data/data/com.newsrob/databases/webview.db lr-x-- root root 2010-06-14 20:10 34 - /system/fonts/DroidSans-Bold.ttf lrwx-- root root 2010-06-14 20:10 35 - /dev/ashmem lrwx-- root root 2010-06-14 20:10 36 - /dev/ashmem lrwx-- root root 2010-06-14 20:10 37 - /data/data/com.newsrob/databases/webviewCache.db lrwx-- root root 2010-06-14 20:10 38 - /dev/ashmem lrwx-- root root 2010-06-14 20:10 40 - /dev/ashmem lrwx-- root root 2010-06-14 20:10 41 - /dev/ashmem lrwx-- root root 2010-06-14 20:11 42 - /dev/ashmem lrwx-- root root 2010-06-14 20:11 43 - /dev/ashmem lrwx-- root root 2010-06-14 20:10 45 - /dev/ashmem (The version with the bug had a couple of more lines pointing to my currentArticle file).

You can reproduce the issue every time? Maybe then it is just a coincidence
that it doesn't happen anymore to my users?! Or there is something else at

Anyway, no, unfortunately not really. This seems only to happen on the
Incredible. What I am 99% sure of is that this is related to the hw
accelerated zoom controls (a user found out through testing). In NewsRob
I
meanwhile disable them for the Incredible. No issues since then.
Do you use WebView's built-in zoom controls at all?

Re: [android-developers] Re: Using a ListView and an Adapter: How to use notifyDataSetChanged()?
Hey Streets,
thanks.
Actually I already run this on the UI thread.
Here is my code (from a ListActivity):
updateCursorRunnable = new Runnable() {
public void run() {
updateCursor();
refreshUI();
}
};
Above you see the Runnable that later on will be executed on the UI
thread.
Here are the implementations: (I didn't cut anything out this time, maybe
I making in error in the unimportant stuff. If you see something else that
needs improving, like the changing of cursors, let me know.).
private boolean updateCursor() {
boolean cursorChanged = false;
if (dbQuery.hasChanged()) {
final Cursor oldCursor = listAdapter.getCursor();
if (oldCursor != null)
stopManagingCursor(oldCursor);
final Cursor cursor =
getEntryManager().getContentCursor(dbQuery);
startManagingCursor(cursor);
listAdapter.changeCursor(cursor);
// listAdapter.notifyDataSetChanged();
cursorChanged = true;
} else {
Timing t = null;
if (NewsRob.isDebuggingEnabled(this))
t = new Timing(ArticleListActivity::requery, this);
// listAdapter.notifyDataSetChanged(); doesn't work. use requery
// instead
listAdapter.getCursor().requery(); * -- That's what I
mean. Would prefer notifyDataSetChanged.*
if (t != null)
t.stop();
}
return cursorChanged;
}
void refreshUI() {
((BaseAdapter) getListAdapter()).notifyDataSetChanged();
updateButtons();
updateControlPanelTitle();
refreshProgressBar();
if (getListAdapter().getCount() == 0 !isTaskRoot())
finish();
}
And the Runnable is triggered like this:
@Override
public void modelUpdated() {
Timing t = new Timing(modelUpdated(), this);
runOnUiThread(updateCursorRunnable);
t.stop();
}
Any ideas?
Cheers,
Mariano

I don't know your code, but it looks like the notifiyDataSetChanged()
(like many other methods that can update the UI) needs to be called on
the main GUI thread.
You need to get hold of a View or a Hander (that was created on the
main GUI thread, e.g. in your onCreate()) and call 'post' on it:
// the code is executed by your background thread
... do stuff ...
...
// communicate that the list needs updating
viewOrHandler.post(new Runnable() {
public void run() {
myListAdapter.notifyDataSetChanged();
}
});

Re: [android-developers] Android cursor lifetime
The code you show doesn't contain the issue you describe as there is no code
that would use the cursor.
It seems strange that you close the database before reading from the
cursor.
The usual course of events is open the database, create the cursor, read
from the cursor, close the cursor, close the database.
Btw. In Java variable names start with a lower case letter.

Is this a timing issue of some sort? Has it anything to do with the

debug through the code.
//Open the database

[android-developers] Easy way to find out the current activity in unit tests?
Hi, I want to test an activity that might be already finished() and the control flow has moved on to another activity. Hence in a test I would like to make sure first that I am still on the activity that I want to test.

But using Activity.getWindow().getDecorView() and View.getRootView() both
returned the same View, but it doesn't have the status bar as a child:

What's up with that? Is it hidden from ordinary apps? Could I still tap
into its animation?

[android-developers] Layout Issue: Status Bar Space Remains Empty || Status Bar Animation
(1)
I have an issue with the following code:
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN);
On my emulator this seems to work fine. The status bar disappears and the
empty space is filled with the content view. However on my Nexus One this
sometimes works and sometimes the empty space remains empty/black.
Any idea why this happens?
I tried to counteract this, but my naive approach wasn't fruitful:
handler.postDelayed(new Runnable() {
@Override
public void run() {
v.getRootView().invalidate();
v.getRootView().requestLayout();
v.getRootView().forceLayout();
}
}, 800);
I tried those things from above separately, synchronously and delayed.

into that with my own animation. To do that I tried to find the status bar.
But using Activity.getWindow().getDecorView() and View.getRootView() both

Re: [android-developers] Layout Issue: Status Bar Space Remains Empty || Status Bar Animation
Ok, I see. That also means that I can't sync my animation to the default
hide animation from the status bar, right?
Any idea what to do about the layout issue referred to as (1) above?

Re: [android-developers] Re: On using themes?!
Hi Dianne. Thanks very much, almost there. I understand the procedure, it would do what I want, but I run into an exception: D/NewsRobDefaultExceptionHandler( 1839): Caused by: java.lang.UnsupportedOperationException: Can't convert to color: type=0x2 D/NewsRobDefaultExceptionHandler( 1839): at android.content.res.TypedArray.getColor(TypedArray.java:273) D/NewsRobDefaultExceptionHandler( 1839): at android.graphics.drawable.GradientDrawable.inflate(GradientDrawable.java:647) D/NewsRobDefaultExceptionHandler( 1839): at android.graphics.drawable.Drawable.createFromXmlInner(Drawable.java:788) D/NewsRobDefaultExceptionHandler( 1839): at android.graphics.drawable.Drawable.createFromXml(Drawable.java:729) D/NewsRobDefaultExceptionHandler( 1839): at android.content.res.Resources.loadDrawable(Resources.java:1690) This happens when using it the way we described here in a drawable xml. However to better understand the error I used it on other attributes and when using it on the background attribute of a View it works. Maybe this approach is incompatible with drawables that are expressed in xml? Btw. Is there any way to get the actual #rgb string for a color from a theme?

Re: [android-developers] Re: How to debug BadTokenException?
My main issue is to find out what is really causing the BadTokenException. Any way how to find out which code initiated the message that caused the BadTokenException or which activity was expected to be running. On Sun, Dec 20, 2009 at 1:03 PM, Chander Pechetty cspeche...@gmail.comwrote: As an example take the case of Market App. It doesn't give any toast or progress when you leave the app. Once the user leaves the app for whatever reason, only a notification is given if the download fails/ succeeds. Any progress dialogs you have when you leave the app should be dismissed/cleaned up in the onPause. Depending on what kind of app yours is, you can either show a notification (may be from the service once the Task is completed, after it attempts several retries in case of error) using the NotificationManager, or I would just cancel the Task if I was using a AsyncTask. I wouldn't want a toast or progress result/or a force close show up when I receive a call, or trying to use some other app; those make sense only when I am looking at your app. On Dec 19, 10:38 pm, Mariano Kamp mariano.k...@gmail.com wrote: Thanks for your help here.

Pressing a back button usually finishes the activity, so if you have created for discussion sake created an static ListAdapter and passed it (this), an activity instance, this static adapter can no longer be used for showing dialogs etc. with the previous contexts.

Re: [android-developers] Re: Extracting colors from Themes?
Hey Nick, that's the thing. It's not that easy. Checkout what I wrote in my initial post: item name=colorBackground@android:color/background_dark/item item name=textColorPrimary@android:color/primary_text_dark/item They basically look the same right? And they are both public, right? However so far I have only been able to pry the RGB values from the framework's hands for the first, but not the second. And I think it's my fault. It is not straight forward. I think you need to possibly deal with drawables (hopefully not, as this would never give me rgb values) and color state lists. That's the reason I was looking for documentation and sample uses in codesearch.google.com, but to no avail.

No, I could also hardcode the colors and that is what it seems I will have to do. In my particular case it won't make much difference at the moment.

I would have preferred to be a model citizen on the Android platform and use the themes. Hardcoding might be the quickest solution, but would fail if I want to use platform properties that are overwritten by vendor themes. To give you an example. On a stock Android device you'll see an orange background behind a selected list item, on an HTC sense device it would be green instead.

[android-developers] How to debug SIGSEV?
Hi,
I am wondering if there is any way to debug a SIGSEV? I have not much
experience with those native crashs. This issue only seems to happen with
the HTC Incredible and I would at least guess that my Java code cannot be
the actual cause, but maybe there is something I can do to avoid triggering
it?
Where can I find more information? Is it possible to see which of my code
lines triggered it?

Re: [android-developers] Re: Extracting colors from Themes?
Hey Pat. Thanks for your chipping in. No, I could also hardcode the colors and that is what it seems I will have to do. In my particular case it won't make much difference at the moment. For now I just need two values and they correspond to the light and dark. But for the future my needs will grow and it is also not so much fun to maintain a shadow theme administration on the side. I would have preferred to be a model citizen on the Android platform and use the themes. Hardcoding might be the quickest solution, but would fail if I want to use platform properties that are overwritten by vendor themes. To give you an example. On a stock Android device you'll see an orange background behind a selected list item, on an HTC sense device it would be green instead. Also as themes look so central to me, I was kind of hoping that I just missed the relevant documentation and that somebody else would point me to RTFM ;-) Cheers Mariano On Tue, Apr 27, 2010 at 9:38 AM, patbenatar patbena...@gmail.com wrote: Do you need to be doing this programatically? You could always take a screenshot of your phone [either using DDMS on a non-rooted device or the PicMe app on a rooted device] and then grab the colors using Photoshop or any image editing software.

Re: [android-developers] Re: Service.startForeground() messes with scheduling?
Now we have this great article: http://android-developers.blogspot.com/2010/04/multitasking-android-way.html Services can further negotiate this behavior by requesting they be considered foreground. This places the service in a please don't kill state, but requires that it include a notification to the user about it actively running. This is useful for services such as background music playback or car navigation, which the user is actively aware of; when you're playing music and using the browser, you can always see the music-playing glyph in the status bar. Android won't try to kill these services, but as a trade-off, ensures the user knows about them and is able to explicitly stop them when desired. But like in the API documentation it doesn't mention that the thread/process gets a prio boost when running with the foreground flag. On Tue, Apr 13, 2010 at 6:42 PM, Mariano Kamp mariano.k...@gmail.comwrote: Ok, I'll explain in detail. There are two issues in this story: (a) killability of the service (b) execution prio of the service In the good old days I just used Process.setThreadPriority(Process.THREAD_PRIORITY_LOWEST) in my service and things went wonderfully. My sync service ran and took as much CPU was available, but the foreground app got all it needed too. In rare cases my service was shot down, but as my service could deal with that it was more a matter of efficiency than of data loss, so it was ok. Progressively over time this happened more frequently though. With information from you that we discussed on this list the story looked to me like this: It became en vogue for many popular services to call setForeground(). That lead to my services being shot down much more frequently, to the point where it became really painful because my service sometimes didn't even last for two seconds. At the time I understood from what you said that I should consider calling setForeground() and that you will make it no-op in a future release and at the same time introduce a new API to replace the old one with the addition that a notification needs to be shown, so that the user sees what's going on and can punish apps that misuse this feature. Now it took some time for me to get to the new API, because I need to implement a useful notification first. To make the new notification useful I rewrote my progress reporting, introduced remote views etc. to show the sync phases and their progress in the notification. I also let the user set if s/he wants to see the notification and get the added stability or not. The old setForeground() only had an effect on the killability of the process, but not on the scheduling priority. The priority I was then able to set independently to low as I don't want to slow down the foreground app in recognizing gestures or other stuff in the foreground that needs low latency. With the advent of startForeground() this doesn't work anymore, because signaling in the foreground, killability and scheduling priority seem to have been rolled into one. It would be great if those things could be independently controlled like it was possible before. And maybe it still is today? Process.setThreadPrio() doesn't do the trick anymore though. Don't get me wrong it is ok, when my activities sometimes get killed. If there were API for that I would also let the OS know when I would prefer not to (startCriticalSection()) and when it is cool to kill my activities. As we are on the topic. It is not so cool to be just shot down. I would prefer to get a signal that I am about to be shut down and get some time to finish what I am doing in a grace period and then clean up (and save my state). This would even be ok when this trigger would come earlier than the OS actually absolutely needs to do it. Ok, now back to your question. Let me give you two examples. One is not so much of a problem today, I just try to explain what kind of uses I see, the other one is what this thread is about. (a) I store articles' metadata in a sqlite database in the phone memory and the actual content (html, css, images) on the sd card. As part of the sync some articles are removed. So I run over all articles that are eligible for removal in the database. If I would get a signal to clean up as outlined above I would break before I start deleting a new article. But back to what is implemented today. For each article I have to remove the database record and the files on the sd card. The former is very fast, the latter is slow. It can happen that my process is suddenly killed in the middle of the removal of an article. Hence I first removed the assets on the sd card, then the database record. This way in the next sync I can clean up the rest and only have the issue that between syncs (or restarts) some assets are missing and articles are displayed with errors. It would be *nicer* if I could invoke startCriticalSection() for the removal of each article
[android-developers] Extracting colors from Themes?

[android-developers] How to use WebView in Offline mode? Can I dynamically revoke permissions?
Hi, I am want to use JavaScript to process some HTML pages in the background. WebView seems to be a great basis to do this. There is one issue though. I don't want to display the web page and its images/stylesheets right away, so it is a waste of bandwidth when the stylesheets and images are downloaded. I am wondering how to tell WebView not to do that. I tried WebSettings.setLoadsImagesAutomatically(false), but this still loads the stylesheets. WebView.setNetworkAvailable(false) is more an information for WebView than a switch. Overriding WebViewClient.shouldOverrideUrlLoading(..) didn't work either. Any idea how to do this? One thing that works is not giving the app the required Internet permission. Unfortunately it is not that simple, because at other times I want to display the processed pages and then it should download the images/stylesheets ;-( But still is there some way that I can use this permission thing? Can I dynamically revoke the permission? For a single thread or process? Cheers, Mariano -- You received this message because you are subscribed to the Google Groups Android Developers group.

Re: [android-developers] Re: unable to open database file after OS upgrade
I had a look into it and this approach doesn't work for me. When using the SQLiteOpenHelper you cannot pass in this flag. I tried to work around the SQLiteOpenHelper first, but then it delegates to the context, which itself uses private API and now have to copy/patch at least four classes. I also found a reference to private API (FileUtils) that uses some obscure modes that I don't want to touch as I don't really understand them. I fear to take a problem that a couple of hundred users of my app have to a problem that will affect every user ;) But thanks for your hint anyway.

Re: [android-developers] Re: Service.startForeground() messes with scheduling?
example: The Android download service. What I am writing here is just from observations as user, I haven't looked at the API or the code. (And I might be totally wrong, because I tried a couple of times to download a video using the download service and it never completed). Anyway, some http servers allow retries, some don't, so for the later it would be very unfortunate if the download process gets killed after 50 MB of a 100MB file, because the download service would need to re-download the 50MBs after a restart again. Now the download service sports a notification, so it may use the new API, but that would clearly be wrong as it also boosts the scheduling prio which is totally the wrong thing to do here as the download doesn't need low latency at all. I just think it would not be a practical problem, because downloads tend to be I/O bound almost 100% of the time. But I still hope you see the picture I am trying to convey here?

The not-too-unreasonable assumption the SDK makes is that something that is supposed to be in the foreground is supposed to be in the foreground. I mean, foreground is in the method's name. There's no question the documentation could be stronger, though. That being said, your choices are: 1. Continue using startForeground() and either live with the complaints or modify your service to be less CPU-intensive, or 2. Stop using startForeground() and modify your architecture to better support the service being shut down Since Android applications have to support their services being shut down (via task killers, the Services screen in Settings, etc.), I would think #2 would be the better answer, but that's your call. -- Mark Murphy (a Commons Guy) http://commonsware.com | http://twitter.com/commonsguy Android Training in NYC: 4-6 June 2010: http://guruloft.com -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: Service.startForeground() messes with scheduling?
*bump*
It seems that the implementation of startForeground() delegates to this
code:
public void setServiceForeground(ComponentName className, IBinder token,
1781 #127f1bc903f2e1c4_l1781int id, Notification
notification, boolean removeNotification) throws RemoteException {
1782 #127f1bc903f2e1c4_l1782 Parcel data = Parcel.obtain();
1783 #127f1bc903f2e1c4_l1783 Parcel reply = Parcel.obtain();
1784 #127f1bc903f2e1c4_l1784
data.writeInterfaceToken(IActivityManager.descriptor);
1785 #127f1bc903f2e1c4_l1785

1787 #127f1bc903f2e1c4_l1787 data.writeInt(id);
1788 #127f1bc903f2e1c4_l1788 if (notification != null) {

1792 #127f1bc903f2e1c4_l1792 data.writeInt(0);
1793 #127f1bc903f2e1c4_l1793 }
1794 #127f1bc903f2e1c4_l1794data.writeInt(removeNotification ? 1 : 0);
1795 #127f1bc903f2e1c4_l1795

1796 #127f1bc903f2e1c4_l1796 reply.readException();

Which isn't all that more helpful ;-( I don't see that it messes with

making this foreground/background service more unkillable. It seems just to
be the IPC code.
Any ideas?

Make this service run in the foreground, supplying the ongoing notification
to be shown to the user while in this state. By default services are
background, meaning that if the system needs to kill them to reclaim more
memory (such as to display a large page in a web browser), they can be
killed without too much harm. You can set this flag if killing your service
would be disruptive to the user, such as if your service is performing
background music playback, so the user would notice if their music stopped
playing.

Re: [android-developers] Re: Service.startForeground() messes with scheduling?
My point is that the documentation says nothing at all about raising the execution prio, but you say now that it does, right? What the documentation says is that startForground() helps that the process doesn't get killed and that's what I was after, because it is a costly process wasting bandwidth to be killed in a part that I cannot resume without starting over. On Mon, Apr 12, 2010 at 9:26 PM, Dianne Hackborn hack...@android.comwrote: Yep startForeround() does what it says -- tells the system it should treat your service as if it is in foreground, something the user is aware of. A typical example is background music playback, which needs to get as much CPU as it needs in order to avoid a bad user experience. Generally, if you want your threads to run in the background, that would imply to me that your service is not one that wants to run in the foreground so should not be requesting to do so.

Quoting myself: ...but a persistent concern for game developers on Android is the impacts that external forces have on their frame rates. For example, a year ago, the big concern was garbage collection going on in other processes -- garbage collection takes CPU time, even if that work is being done in a totally separate Linux process from the game itself. To counteract this, the core Android team made some improvements in Android 1.6, relegating all background processing to a class that is capped in terms of CPU utilization, leveraging some Linux process and thread control frameworks. Garbage collection in those background processes will no longer hog the CPU. Hence, games can run with minimal interference...so long as background processing stays in the background. (from http://www.androidguys.com/2010/03/16/code-pollution-background-foreground/ ) I suspect that startForeground() means the service will run with foreground priority, rather than residing in the background process class. -- Mark Murphy (a Commons Guy) http://commonsware.com | http://twitter.com/commonsguy Android Training in NYC: 30 April-2 May 2010: http://guruloft.com -- You received this message because you are subscribed to the Google Groups Android Developers group.

Re: [android-developers] Re: Service.startForeground() messes with scheduling?
1) CPU is not a problem per se. My process can happily be starved of CPU, but as it needs to do xml parsing it does task the CPU albeit at it's lowest prio. 2) As I said I rely on an external API that doesn't understand incremental updates. Anyway, I think there is no good solution and the usefulness of this thread is nearing zero now, so I will stop before I waste anymore of everybody's time. Thanks so far.

I'm saying what Ms. Hackborn confirmed in her reply to my post -- startForeground() elevates the service's process to the foreground priority class. The not-too-unreasonable assumption the SDK makes is that something that is supposed to be in the foreground is supposed to be in the foreground. I mean, foreground is in the method's name. There's no question the documentation could be stronger, though. That being said, your choices are: 1. Continue using startForeground() and either live with the complaints or modify your service to be less CPU-intensive, or 2. Stop using startForeground() and modify your architecture to better support the service being shut down Since Android applications have to support their services being shut down (via task killers, the Services screen in Settings, etc.), I would think #2 would be the better answer, but that's your call. -- Mark Murphy (a Commons Guy) http://commonsware.com | http://twitter.com/commonsguy Android Training in NYC: 4-6 June 2010: http://guruloft.com -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Hard to describe ... How to quickly scan through all rows?! How to pass a cursor between two activities?!
Hi,
I have an app that has a list view of messages and a detail view. If you
click on a message in the list view the detail view is opened for the
message in the row you clicked on.
In the detail view you also can go back and forth to other messages. So I
pass in the position of the row the user clicked on and the criteria I need
to rebuild the cursor like I did for the list. Then I use
Cursor.moveToPosition() to get to the selected row.
So far so good. There is only one issue, when an import is running in the
background that inserts new (or deletes aged) messages then between the time
of the click and the time the detail view queries the database again it
maybe that the position is not valid anymore.
Any idea how to deal with that?
I tried to pass in a key instead and then go through all rows until I find
the one that has the same key, but this takes a real long time and doesn't
seem feasable at all. But maybe I am doing it wrong. It looks something like
this:
while (contentCursor.moveToNext()) {
if (42 == contentCursor.getLong(0))
break;
}
Any better way to do that in general?
I could try what happens when I pass in the position also and start from
there. Usually that should work and when it doesn't then I could scan all
messages?! The problem is, scanning all say 1,000 articles may take more
than 5 seconds on a G1.
Cheers,
Mariano

[android-developers] Non-stretchable background images
Hi, I want to generate background drawables for buttons and I am wondering if there is any way to specify that the button can stretch, e.g. when using fill_parent, but the image in it should not stretch? I want to use the extra space for the touch area, but not have the icons on it look all different and stretched beyond recognition. So I am basically looking for something like that: http://developer.android.com/reference/android/widget/ImageView.ScaleType.html But of course it should work with Buttons. I know I could use nine patchs, but I have more than 20 icons and even if my ADD would allow me to do this tedious task once for every 20 images for every resolution I don't think I would ever change the icons afterwards which can't be the solution.

Sorry. I meant to say remote views like in the subject ;-) I currently update the remote views to which I kept a reference and then notify again with the same Id.

Those two concepts are not strictly tied, AFAIK. A Service would update the app widget the same way regardless of whether or not it called startForeground(). BTW, I don't know what a remote widget is. I am just assuming you are referring to home screen app widgets.

[android-developers] PendingIntents in Notifications
I would like to show a notification that displays the progress of an ongoing operation, but at the same time the remote view should contain a cancel button to stop the ongoing operation.

[android-developers] Trouble understanding launching intents
Hi, I have an hypothetical app that has two activities: A (List), B (Details). A can be launched and can itself launch B. I also have a widget that can also launch B via the use of an PendingIntent. Activity B looks at the Intent's extras ie1 and ie2 when created and shows different data then. The behavior I would like to see is A launches B. When I press HOME and then go to a widget that itself launches B then the existing B should be replaced by the new B with different extras (ie1 and ie2). The new B should replace the existing B. Also what I am seeing is when I go back HOME after seeing B that was launched with ie1=x and then launch B from the widget again with ie1=y I still get to see the old B with ie1=x. It doesn't really matter what configuration/approach I am using now as I am willing to completely change it. But for illustration purposes I'd like to share a couple of things that I use or used. I put all extras additionally into the data uri as parameters, because it seems that the extras alone are not taken into account when comparing Intents. I thought from reading the documentation that launching with category=Intent.CATEGORY_LAUNCHER and flags=Intent.FLAG_ACTIVITY_CLEAR_TOP should do what I expected, but it doesn't. In the declaration of A and B I set clearTaskOnLaunch=true. Anything special to take into account when launching those intents from a PendingActivity associated with a remote view? I found it interesting that when launching out of this context the flags always contained Intent.FLAG_ACTIVITY_NEW_TASK (0x1), even though *I* didn't set it. Instead I set CLEAR_TOP (0x04). Another thing that I would like to know is how could I configure/program it that a launch of B from the widget completely clears the task's stack, basically like clearTaskOnLaunch, but when firing an intent. With all of this what I really like to avoid is that Gmail-like BACK-orgy, where I sometimes have to press BACK five to eight times to reach the home screen. This seems to be the same problem. Opening Gmail from the launcher, from shortcuts and from the new-mail notification does that.

Re: [android-developers] Application losing SharedPreferences and Sqlite database on Droid
I get lots of these (database disk image is malformed). Also unable to open database file, error code 14: unable to open database file, database or disk is full and many more. I can't put my finger on what the issue is though. unable to open database file is my current favorite. It seems to happen more frequently after the user upgraded his or her OS, this happens with custom ROMs, but also with official updates. It would be fantastic if the OS would provide a crash reporter that sends those issues to a central place, so that Google's Android developers can see the numbers of what causes trouble and either fix the issues or educate the developers.

Re: [android-developers] AccountManager.getAuthToken() problem with more than one app
This whole Auth 2.0 thing is a total mess. Did you test it on Android 2.0.1
devices? It didn't crash for you there? Can you support hosted accounts?
I think I will give up on this until Google documents how to use their
implementation (the Google one, not the Android framework). There is just
already too much time sunk here.
Anyway, regarding your actual issue, did the Auth mechanism ask you twice to
allow access to the selected account? I am not quite sure how it determines
the caller, but maybe it might not be the calling app, but the certificate
it was signed with that makes the difference. Did you use the same
certificate to sign both apps?

[android-developers] Need help with Remote Views. Not updating anymore after the first update?
I have remote views that are updated during their configuration. So far so good.
When later on the state they should monitor changes I want to update
them again and I use the same code to alter the remote views, but
nothing happens. When looking at the remote views in the debugger I
can see that the remote views' mAction instance var does accumulate
all my changes (setTextViewText etc.), but the actual widgets don't
change.
Any idea what might be wrong or where I can look at? I know it is
probably something stupid, but I don't see it and it's not for a lack
of trying.
I tried loads of different approaches, but here is the current code:
firing the update:
AppWidgetManager awm = AppWidgetManager.getInstance(ctx);
int[] appWidgetIds = awm.getAppWidgetIds(new ComponentName(ctx,
UnreadWidgetProvider.class));
for (int appWidgetId : appWidgetIds) {
System.out.println(EM.awm.updateWidget appWidgetId= + appWidgetId);
awm.updateAppWidget(appWidgetId,
UnreadWidgetProvider.buildUpdate(ctx, appWidgetId));
}
create the remote views:
public static RemoteViews buildUpdate(Context context, int appWidgetId) {
System.out.println(buildUpdate appWidgetId= + appWidgetId);
EntryManager entryManager = EntryManager.getInstance(context);
WidgetPreferences wp = entryManager.getWidgetPreferences(appWidgetId);
RemoteViews updateViews = new RemoteViews(context.getPackageName(),
R.layout.unread_widget);
if (wp == null) {
System.out.println(In configuration. Nothing stored yet for
appWidgetId= + appWidgetId);
return updateViews;
}
System.out.println(using dbq= + wp.getDBQuery() + appWidgetId= +
appWidgetId);
int count = getCount(entryManager, wp.getDBQuery());
System.out.println(count= + count);
System.out.println(label= + wp.getLabel());
updateViews.setViewVisibility(R.id.unread_count, count 0 ?
View.VISIBLE : View.INVISIBLE);
updateViews.setTextViewText(R.id.unread_count, String.valueOf(count));
System.out.println(wp.getLabel()= + wp.getLabel() + !);
// updateViews.setViewVisibility(R.id.label, wp.getLabel() !=
// null ? View.VISIBLE : View.INVISIBLE);
updateViews.setViewVisibility(R.id.label, View.VISIBLE);
if (wp.getLabel() != null)
updateViews.setTextViewText(R.id.label, wp.getLabel());
Intent intent = new Intent(context, ArticleListActivity.class);
PendingIntent pendingIntent = PendingIntent.getActivity(context, 0,
intent, 0);
updateViews.setOnClickPendingIntent(R.id.unread_count, pendingIntent);

Re: [android-developers] Re: Android, send me logs! - code library for detecting force-close and sending logs
What's nice about Apple's approach here is that developers don't have to do anything... it's a good way of improving the code quality for *all* apps. I was pretty surprised and happy when it came online a month or two ago because it confirmed that what was crashing across our user base were known issues. Most of the battle is getting *any* information about how the app is behaving in the field, so the auto-crash reports are really nice. I don't think there's an inherent conflict with Android's openness. The crashes are anonymized, and developers and users do chose to go through the Android Market -- which unlike Apple isn't the only way to get apps. And it would give feedback to the Android developers what kinds of bugs appear, because their users (the devs) don't seem to grasp the API or because there are bugs in the system that they would have consider minor until they see how often they really occur. -- You received this message because you are subscribed to the Google Groups Android Developers group.

Re: [android-developers] Re: Widget does not render on wvga854 ?
Oh and I forgot to mention that in the emulator the debugger doesn't seem to work anymore since I use widgets. But this might be not related and maybe my emulator just has some defect?

[android-developers] App Widget Lifecycle?
Hey guys, I am bit puzzled by an app widget's lifecyle. When I create a widget my own configuration activity is launched, some data is entered, I store this data some place and call finish on my config activity like this: Intent resultValue = new Intent(); resultValue.putExtra(AppWidgetManager.EXTRA_APPWIDGET_ID, appWidgetId); setResult(RESULT_OK, resultValue); finish(); Now I would expect to see something like that in my log: I/System.out( 312): onReceive...=android.appwidget.action.APPWIDGET_ENABLED I/System.out( 312): onReceive...=android.appwidget.action.APPWIDGET_UPDATE But as a matter of fact those log entries from above are created when the configuration activity is *started*. Is that right? Am I doing something wrong here? Should I invent some artificial limbo/default state for the widget that can be displayed when it is in its configuration mode?

Re: [android-developers] A Widget that looks like a launcher icon?
Thanks guys. The thing is, it shouldn't look like a widget, but like an active shortcut with a badge representing the unread count. My shortcuts to labels in Gmail have the drawback that I always have to open them to see what's in them. It would be great if there were a way to use common functionality to meet the look of the particular platform, but I understand there isn't such a functionality at the moment.

Re: [android-developers] A Widget that looks like a launcher icon?
Sure, that was my original idea. I should have mentioned the 1x1 size. The Gmail thing was just an example and I was talking about the actual GMail shortcuts. They don't show the unread count so you have to click them to know what's in them. In my case it would be shortcuts to Google Reader labels/feeds etc. I am currently trying to make those 1x1 widgets look like shortcuts, but then I read what you guys wrote and see that my efforts are to be futile given that there are other look and feels. Still I have an app icon, a label and an unread count. Everything I tried looks strangely out of place as it lives with all the other shortcuts on the same home screen.

[android-developers] Issue with Android 2.0 Account API / getAuthTokenLabel() results in Resources$NotFoundException: String resource ID #0x0

using the new Account API to access Google accounts I have code that works

I don't think the code helps, but before you ask:
accountManager.getAuthToken(selectedAccount, ah, null, myActivity,
new AccountManagerCallbackBundle() {
public void run(android.accounts.AccountManagerFutureBundle f) {
try {
// Don't even get
here on an Android 2.0.1 device
String authToken = f.getResult().getString(AccountManager.KEY_AUTHTOKEN);
doCoolAndExcitingStuffOnAnAndroid2Dot1Device(authToken);
}
}, handler);
In the same spirit: I did not run it on the emulator, because the API is
not there, not even when I create an emulator with the Google API.
I don't see the source code for
com.google.android.googleapps.GoogleLoginService, so I can't check that.
Cheers,
Mariano

[android-developers] Android 2.0.1 / SDK Level 6 or 7 or what?
I see changed behavior in WebView on 2.0.1 devices, so I just read up (however little there was - very quick read) on WebSettings.getDefaultZoom(). It says Level 7. I checked the 2.0.1 SDK and it returns Level 6. However when checking for the method getDefaultZoom() with reflection, yay, it is there. That also explains the changed behavior. Am I missing something here or is this the right approach? Should I check for the existence of methods to find out what version I am dealing with? What happens when an existing behavior changes without adding new methods, like WebView did between 1.6 and 2.0? What is the level information in the API docs good for? -- You received this message because you are subscribed to the Google Groups Android Developers group.

The documentation for that method says that it is available on level 3:

Re: [android-developers] VerifyError issue with Android 1.5 devices

Ah, I see. That would make sense. Then I will revert back my code to use reflection again and put the zoom controls in the GUI myself if the method is not there. Do you know which device specifically? Sounds like another one of those awesome device-specific issues. If you know which device, do a search and see if it's a known issue with it. Yes, I do. At least about the one user that sent the report: 01-13 12:08:17.068 D/NewsRobDefaultExceptionHandler( 407): -- Android Version: sdk=3, release=1.5, inc=138607 01-13 12:08:17.068 D/NewsRobDefaultExceptionHandler( 407): -- Custom ROM: Stock Android 01-13 12:08:17.068 D/NewsRobDefaultExceptionHandler( 407): -- Device: sapphire 01-13 12:08:17.068 D/NewsRobDefaultExceptionHandler( 407): -- Model: HTC Magic Two more users reported in the Market comments it would force close on their Heroes. Might be the same issue, but it is strange that they didn't send the automatic bug report then. I googledhttp://www.google.com/search?hl=enq=HTC+%2BMagic+%2BsetBuiltInZoomControls+-map+-mapViewaq=foq=aqi=it, but didn't find anything, except my post and reports about the Map's setBuiltInZoomControls method missing. I'll do the reflection thing from above and hope that I find an affected user that can try it out. Love your app BTW =) Awesome. Thanks for letting me know. It looks like (see above) you have to suffer through another bugfix update though ;-) -- You received this message because you are subscribed to the Google Groups Android Developers group.

how do you do that?
I tried:
receiver android:name=com.test.MyApp.UpdateReceiver
intent-filter
action android:name=android.intent.action.PACKAGE_ADDED/
action android:name=android.intent.action.PACKAGE_REMOVED/
action android:name=android.intent.action.PACKAGE_REPLACED/
data android:scheme=package android:path=com.test.MyApp/
/intent-filter
/receiver
And a bunch of variations of android:path, but I couldn't get it to
only notify me when it was my app.

Please register for only your specific package name, not every package,
so
your app doesn't get launched every time another app is installed or
uninstalled.

oh, okay, so I added this line to my manifest --
data android:scheme=package/
and it seemed to work. I get a removed followed by a replaced. as is
documented here:
http://developer.android.com/intl/fr/guide/appendix/faq/framework.html
now I just gotta figure out how to remove/replace the app widget when
i get this... anyone??

when I re-install an application, i get PACKAGE_REMOVED followed by
PACKAGE_ADDED.
I never see PACKAGE_REPLACED. any ideas why? And actually, I never
see any of the PACKAGE_* actions except in LogCast -- I cannot get my
broadcast receiver to get the events.
i'm doing this in the emulator using adb --
adb install -r MyApp.apk
My Android manifest has these lines in it:
application...
...
...
receiver
android:name=com.test.MyApp.UpdateReceiver
intent-filter
action
android:name=android.intent.action.PACKAGE_ADDED/
action
android:name=android.intent.action.PACKAGE_REMOVED/
action
android:name=android.intent.action.PACKAGE_REPLACED/
/intent-filter
/receiver
...
...
/application
And my UpdateReceiver.java looks like this:
package com.test.MyApp;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
public class UpdateReceiver extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
String action = intent.getAction();
System.err.println(action: + action);
}
}
