[android-developers] Drawable or Uri for Notification icon
The Notification API allows to set a drawable resource id for the icon of a notification. This drawable resource id is used to put the icon in the status bar and in the expanded window shade. This is a limitation if the icon images are to be represented by a Drawable or from a content provider at runtime. I propose that the Notification class adds fields (or methods) that would allow to set a Drawable or an Uri for the notification icon. This Drawable or Uri would then be used by the system notification service to put the icon in the status bar and in the expanded window shade. Android team, could you provide your comments? --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Developers group.

Make use of Handlers to tell the main thread when the other thread has
stopped or completed its task.
final Handler handler = new Handler() {
@Override
public void handleMessage(Message message) {
//do something here. Will be done on main thread
}
};
Use it in your thread like this
handler.sendMessage(message);

[android-developers] Re: how can i check landscap orientation ?
If you just want to find the current orientation of the screen, the sensor
manager is just totally the wrong direction to take.
What you want to do is use getResources().getConfiguration() (sorry I
incorrectly previously posted to use getDisplayMetrics()).
You can follow the docs on getRequestedOrientation() to see the (fairly
large) set of possible values it returns and that usually it is not telling
you the actual current orientation:
http://developer.android.com/reference/android/app/Activity.html#getRequestedOrientation()
http://developer.android.com/reference/android/content/pm/ActivityInfo.html#screenOrientation
http://developer.android.com/reference/android/R.attr.html#screenOrientation
So if you are getting SCREEN_ORIENTATION_PORTRAIT or
SCREEN_ORIENTATION_LANDSCAPE from here, you are just finding out that you
had told the system that you want to force the screen to be portrait or
landscape while your activity is in the foreground.
This is what you want to use if you just want to find out the current screen
orientation:
http://developer.android.com/reference/android/content/res/Resources.html#getConfiguration()
http://developer.android.com/reference/android/content/res/Configuration.html#orientation

The Context class has a suite of functions for creating, opening, and deleting databases at the standard location of databases for your app. The SQLiteDatabase class can be used to access a databases at any absolute path. In that case, you are using an absolute path, so use File to delete the database file at that path.

And sure enough, 1280 is returned by a call to glGetError right after the call to glGetIntegerv. So it looks like you can't get the GL_MATRIX_MODE that way on Android. And upon further looking through the code I don't see anywhere that the matrixMode state variable is accessed. So I doubt that you'll have any luck getting it from the java API. If you control all of your OpenGL code you can work around this by using a wrapper to change GL state. It's not ideal, but it should work. That wrapper class could then be queried for the current matrix mode. -Anton On Mar 23, 7:39 am, tcassany tcass...@betomorrow.com wrote: Hello, I just would to know how can I get the currentmatrixmode.

When you 'exit' an application, it isn't necessarily immediately destroyed by the system (see the activity lifecycle documentation), so I suspect that's why the GPS stays active and keeps getting updates. You might want to remove updates in onStop() instead. Probably unrelated, but calling onDestroy from onLocationChanged looks a bit odd? Looks like you will only ever get one update? --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] android http GET 400 error
Hi Android Experts,
i need to make a GET request to the http://www.x.com/server.xml which
takes 3 mandatory headers
hdr1,hdr2,hdr3
i am trying this code
try {
String path = http://x.com/server.xml;;
HashMap parameters = new HashMap();
parameters.put(hdr1,this.hdr1);
if(mUserLoggedIn){
parameters.put(hdr2,this.hdr2);
parameters.put(hdr3,this.hdr3);
}
// Setup the connection
String uri = new String(path);
URL url = new URL(uri);
URLConnection conn = url.openConnection();
HttpURLConnection httpConnection = (HttpURLConnection)conn;
String boundary = myboundary;
conn.setDoOutput(true);
conn.setDoInput(true);
conn.setUseCaches(false);
conn.setRequestProperty(Connection,Keep-Alive);
conn.setRequestProperty(Content-Type,multipart/form-data;
boundary= + boundary);
DataOutputStream wr = new DataOutputStream
(conn.getOutputStream());
// Send the normal form data
int responseCode = httpConnection.getResponseCode();

Vipul Sagare wrote: After spending few days with Services API, here are some of my questions. I would appreciate your answers and any leads to blogs/postings. I have already gone through API reference and APIDemos for AlarmService, LocalService, and RemoteService. - Are there any good sample applications for each? See below. - Wouldn't most applications use Local Service? That is difficult to say in the abstract, though I would not be surprised if more use local services than remote services. - What are some of the applications which would be good candidate for remote services but not for local services? Here are three off the top of my head: 1. You want third-party programs to use the service (even if you are using it locally, it needs to support AIDL interfaces and such for use remotely) 2. You are reusing a service from a third-party program 3. You want part of your application to run with different permissions than another part of your application (e.g., firewalling off certain sections), and so you split part of it out into a remote service -Is there any other resource apart from API reference, APIDemos and dev guide for this topic that one would recommend?(Some of the blogs are a bit outdated) You mean besides (*cough*) various Android books? ;-) In all seriousness, services have not received quite as much attention as activities. There are probably good samples out on anddev.org, and you might consider poking through code.google.com or github's Android projects to see if anything strikes your fancy. -To start an Activity from service, the use of Notification with PendingIntent is the best and only way. Is that correct? Best, yes. Only, no. AFAIK, you can call startActivity() from a service, though your users may threaten you with bodily harm if you do so, since you might be interrupting them in the middle of something else they are doing. -- Mark Murphy (a Commons Guy) http://commonsware.com Warescription: Three Android Books, Plus Updates, $35/Year --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: PendingIntent problem
Intents are cached by the system, and two Intents are not differentiated by their Extras. So your two intents look like the same Intent and the second one is being tossed out. You must differ Intents by their Action/Data/Category. I will sometimes use the Data field to hold a simple ID that is not really a URI to make two intents appear different. Look at the code for Intent.equals() I believe, and you will see that Extras are not considered.

break point in my code everything is executing as I would expect it
to.
If I do not have the code in place, everything shows up in the widget
as I type. My understanding is that if you want everything to be
handled normally then you return a false from the event handlers
otherwise you return a true.
Has anyone else experienced this?

You can try that.

[android-developers] How to display 2 ListViews on the screen at the same time
Hello
I am trying to design a UI which utlizes two ListViews on the screen
at the same time.
Is this possible ?
So here is a quick example of how I was intending to do this.
1) Create an XML which positions 2 ListViews one onto of the other
each ListView having there own ID
ListView
android:id=@android:id/list
android:layout_width=fill_parent
android:layout_height=198px
/ListView
ListView
android:id=@+id/ListView01
android:layout_width=192px
android:layout_height=215px
/ListView
2) Create two string arrays and populate each listview via
ArrayAdapter
private String[] mStrings = {
Abbaye de Belloc, Abbaye du Mont des Cats, Abertam,
Abondance, Ackawi,
Acorn, Adelost, Affidelice au Chablis, Afuega'l
Pitu, Airag, Airedale,
Aisy Cendre};
private String[] mStrings2 = {dsds, qwqwqq, dsdsdsd sdsdsds
, dsdsds sdsds};
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
setListAdapter(new ArrayAdapterString(this, R.layout.row,
R.id.label, mStrings));
setListAdapter(new ArrayAdapterString(this, R.layout.frow,
R.id.ListView01, mStrings2));
}
This does not work.

You cannot use the ListActivity methods for managing the second
ListView. You will need to use findViewById() and handle that ListView
manually.

And sure enough, 1280 is returned by a call to glGetError right after the call to glGetIntegerv. So it looks like you can't get the GL_MATRIX_MODE that way on Android. And upon further looking through the code I don't see anywhere that the matrixMode state variable is accessed. So I doubt that you'll have any luck getting it from the java API. If you control all of your OpenGL code you can work around this by using a wrapper to change GL state. It's not ideal, but it should work.

[android-developers] Re: photo picker Uri issue
This Uri is the logical (not physical) path used by the image content
provider.
If you want to get the physical path to the actual file on the SD-
card, query this Uri:
Cursor cursor = query(photoUri, new String[]
{MediaStore.Images.ImageColumns.DATA}, null, null, null);
String absoluteFilePath = cursor.getString(0);
Now, absoluteFilePath is the physical path to your image, which you
can use in Drawable.createFromPath
Question: Why don't you create a Bitmap instead?
...
InputStream is = getContentResolver().openInputStream(photoUri);
Bitmap bm = BitmapFactory.decodeStream(is);
...
is.close();
I ask this, because it is safer to cache Bitmaps instead of Drawables.
If you cache Drawables, you run the risk of memory leaks. Drawables
have handles to your activity and when your activity gets destroyed
while your Drawables are still cached, your activiy will never be
garbage collected -- memory leak.
Bitmaps don't have this problem. They are basically byte-arrays with
some behavior :).

[android-developers] Re: PendingIntent problem
To correct my previous statement, PendingIntents are cached by the
system, not Intents. The note about how to differentiate Intents
still holds though, so if you need to replace a current PendingIntent
with a new PI that has a new Intent that only differs by its Extras,
be sure to use the flag FLAG_CANCEL_CURRENT so that the cached PI is
not used.
From Intent.filterEquals(o):
Returns true if action, data, type, class, and categories are the
same. == note does not include Extras
From PendingIntents javadoc:
* pA PendingIntent itself is simply a reference to a token
maintained by
* the system describing the original data used to retrieve it. This
means
* that, even if its owning application's process is killed, the
* PendingIntent itself will remain usable from other processes that
* have been given it. If the creating application later re-retrieves
the
* same kind of PendingIntent (same operation, same Intent action,
data,

Intents by their Action/Data/Category. I will sometimes use the Data
field to hold a simple ID that is not really a URI to make two intents
appear different. Look at the code for Intent.equals() I believe, and
you will see that Extras are not considered.

[android-developers] Re: How to display 2 ListViews on the screen at the same time
Thanks !
So yes I got it to work by calling setAdapter on the ListView object.
//setListAdapter for ListView 1
setListAdapter(new ArrayAdapterString(this, R.layout.row,
R.id.label, mStrings));
//Code to display ListView 2
ListView cities = (ListView) findViewById(R.id.ListView01);
ArrayAdapter aa = new ArrayAdapterString(this, R.layout.row,
R.id.label, mStrings2);
cities.setAdapter(aa);
So that works and displays the two ListViews.
Any pointers in how I can now change the behaviour of how Android
deals with interaction between the two lists ?
For Example if I have two ListViews one ontop of another, for me to
scroll the list in the bottom ListView I have to navigate all the way
down through all items in ListView 1 before entering or focussin on
List View2.
How can I program ListView2 to get focus if it is selected via touch ?
I am looking for a function is ListActivity for this but dont find
anything.
Any tips ?
Thanks

Hello
I am trying to design a UI which utlizes two ListViews on the screen

Is this possible ?
So here is a quick example of how I was intending to do this.
1) Create an XML which positions 2 ListViews one onto of the other
eachListViewhaving there own ID
ListView
android:id=@android:id/list
android:layout_width=fill_parent
android:layout_height=198px
/ListView
ListView
android:id=@+id/ListView01
android:layout_width=192px
android:layout_height=215px
/ListView
2) Create two string arrays and populate eachlistviewvia
ArrayAdapter
private String[] mStrings = {
Abbaye de Belloc, Abbaye du Mont des Cats, Abertam,
Abondance, Ackawi,
Acorn, Adelost, Affidelice au Chablis, Afuega'l
Pitu, Airag, Airedale,
Aisy Cendre};
private String[] mStrings2 = {dsds, qwqwqq, dsdsdsd sdsdsds
, dsdsds sdsds};
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
setListAdapter(new ArrayAdapterString(this, R.layout.row,
R.id.label, mStrings));
setListAdapter(new ArrayAdapterString(this, R.layout.frow,
R.id.ListView01, mStrings2));
}
This does not work.
Can anyone advise ?
You cannot use the ListActivity methods for managing the secondListView. You
will need to use findViewById() and handle thatListView
manually.

Hi,
I know that this is common problem, but still I cannot find the

I have two classes:
InternetConnection extends Activity
ConnectionChangeReceiver extends BroadcastReceiver
From ConnectionChangeReceiver I'm calling InternetConnection method
which is refreshing UI when Internet connection is changed. The
problem is that during refresh operation I'd like to showProgressDialogwhich
actually is never visible !!
So broadcast class looks like:
public class ConnectionChangeReceiver extends BroadcastReceiver {
private InternetConnection internetConnection;
@Override
public void onReceive(Context context, Intent intent) {
mRefreshingDialog =ProgressDialog.show(TimeCard.this, , msg,
true);
new Thread() {

login(mResult);
mHandler.post(new Runnable() {
public void run() {
/** doing some UI

internetConnection.refreshUI();
mRefreshingDialog.dismiss();
}
});
}
}.start();
}
}
Do you know why mRefreshingDialog isnotvisible ?

I seem to recall there are various local proxy servers you can use to intercept HTTP traffic, though getting a proxy server to work with the emulator is not terribly easy given the number of questions that seem to come up related to it. Instead, particularly if you are using OS X or Linux as your development environment, I would focus on trying to get curl working. Once you have curl properly downloading the content, converting that into Android code (whether URLConnection or HttpClient) should be relatively straightforward. You might also inquire with whoever is hosting the server if they have any recipes for Web service access. -- Mark Murphy (a Commons Guy) http://commonsware.com _The Busy Coder's Guide to Android Development_ Version 2.0 Available! --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: Drop entire database?
The Context class has a suite of functions for creating, opening, and deleting databases at the standard location of databases for your app. The SQLiteDatabase class can be used to access a databases at any absolute path. In that case, you are using an absolute path, so use File to delete the database file at that path. But unless you are putting your database on the SD card, you would be best off using the Context methods for your database access. Ah ok, I think I get it now. I can just treat the database like a normal file. It wasn't obvious at first that I could go under the covers and manipulate the database via the filesystem API. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Task activity stack always reset when launched from Home
I am just starting on an Android app and I am puzzled about why my
Task activity stack is being reset any time the application is
launched from the Home screen.
I used the ADT tools to create the application in Eclipse.
The main activity is .UserLaunch and it starts the activity .About
when the user presses a button.
If the user then presses HOME and then relaunches the app, .UserLaunch
is displayed and is the only thing on the stack.
.UserLaunch has the launchMode singleTask. .About is standard.
According to the documentation at
http://developer.android.com/guide/topics/fundamentals.html#lmodes:
However, a singleTask activity may or may not have other
activities above it in the stack. If it does, it is not in position to
handle the intent, and the intent is dropped. (Even though the intent
is dropped, its arrival would have caused the task to come to the
foreground, where it would remain.)
The Task stack should be brought to the foreground and .About should
still be displayed.
I added Logging to all of the lifecycle events (edited to remove
timestamps and shorten DEBUG/ and INFO/ to D/ and I/) and you can see
that when HOME is pressed, .About cycles through onPause and onStop
(as expected). Then when the app is again launched, .About is
destroyed and .UserLaunch is restarted

The device can't show these, because the symbols are stripped out of the libraries before they are installed on the device. They do exist in the build tree; since you're doing your own builds, you can find them in the appropriate symbols directory under out/. Given that, you can use arm-eabi-addr2line to convert the symbols, or use gdb/gdbserver to do debugging directly on the device. Make sure you're using the out directory that corresponds to the binaries installed on the device.

[android-developers] Re: Q. Stack trace gives Hex values not function names when core library crashes
Hi While trying to debug native C libraries, upon receiving a SIGSEGV, the core dump thrown does not map address values to symbols as seen in DDMS. As mentioned above this is happening due to stripping of binaries. How can we prevent such stripping in Android or obtain detailed stack trace despite stripping ? Are there any changes we need to make to the Makefiles ? Thanks in advance On Feb 13, 1:47 am, fadden fad...@android.com wrote: On Feb 12, 1:59 am, click...@gmail.com click...@gmail.com wrote: I am looking for little more informations rather than Hex values. Like the backtrace feature where the stack hex values is mapped to the function names and function names are visible. The device can't show these, because the symbols are stripped out of the libraries before they are installed on the device. They do exist in the build tree; since you're doing your own builds, you can find them in the appropriate symbols directory under out/. Given that, you can use arm-eabi-addr2line to convert the symbols, or use gdb/gdbserver to do debugging directly on the device. Make sure you're using the out directory that corresponds to the binaries installed on the device. In any event, discussions about debugging native libraries might be more appropriate for android-porting or android-platform at this time. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Launch / Re-Launch flow
I'm trying to get a handle on the onXXX() flow, but am not sure if what I'm seeing is by-design, or is an artifact of repeated debugging sessions on the emulator. android:launchMode=singleInstance The app extends TabActivity, has a few tabs whose content is set via new Intent, but no heavy application work is being done yet. The question is about relaunching after pressing the home button: Launch from icon: onCreate, onStart, onResume Home button: onPause, onStop Relaunch: sometimes onStart, onResume othertimes onCreate, onStart, onResume In the cases where the relaunch starts with onCreate, pressing the back arrow on the emulator appears to bring a different instance of my application to the front. The only thing that I can figure out on why I'd get the different relaunch flows, is that I'm initially launching the app from Eclipse, making a little change, launching from Eclipse again, repeat, and this is actually creating new instance of my app. But I'm just guessing this matters, I have no idea, as just doing 'launch from eclipse, home key, relaunch from android icon' also has shown the 'onCreate, onStart, onResume' path. Any ideas on why the different relaunch flows? Thanks. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: Task activity stack always reset when launched from Home
You can do adb logcat -b events to see the event log which will include a
line the activity manager prints when finishing an activity, with the reason
why it is doing it.
On Tue, Mar 24, 2009 at 7:24 PM, jseghers jsegh...@cequint.com wrote:
I am just starting on an Android app and I am puzzled about why my
Task activity stack is being reset any time the application is

I used the ADT tools to create the application in Eclipse.
The main activity is .UserLaunch and it starts the activity .About
when the user presses a button.
If the user then presses HOME and then relaunches the app, .UserLaunch
is displayed and is the only thing on the stack.
.UserLaunch has the launchMode singleTask. .About is standard.
According to the documentation at
http://developer.android.com/guide/topics/fundamentals.html#lmodes:
However, a singleTask activity may or may not have other
activities above it in the stack. If it does, it is not in position to
handle the intent, and the intent is dropped. (Even though the intent
is dropped, its arrival would have caused the task to come to the
foreground, where it would remain.)
The Task stack should be brought to the foreground and .About should
still be displayed.
I added Logging to all of the lifecycle events (edited to remove
timestamps and shorten DEBUG/ and INFO/ to D/ and I/) and you can see
that when HOME is pressed, .About cycles through onPause and onStop
(as expected). Then when the app is again launched, .About is
destroyed and .UserLaunch is restarted

[android-developers] Re: Track Ball Problem...
You need to register your activity to the system to tell it that you can handle trackball events directly. If you don't, then the system will emulate the events with key down/up events. I don't know the API to do that. By the way, you can press Delete to enable track-ball mode in the emulator (or even Ctrl-T to toggle between trackball and non-trackball modes). This should help you develop your app. (And I recommend to use a real trackball mouse attached to your machine to test that, it really feels better than using a mouse).

Here is the relevant section of the Manifest:
application android:icon=@drawable/icon android:label=@string/
app_name
activity android:name=.UserLaunch android:label=@string/app_name
android:launchMode=singleTask
intent-filter
action android:name=android.intent.action.MAIN /
category android:name=android.intent.category.LAUNCHER /
/intent-filter
/activity
activity android:name=.About android:launchMode=standard
/activity
/application
Anyone have any ideas why this is always resetting the Activity Stack?
