Re: [android-developers] Re: On using themes?!
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.

[android-developers] Multiple Notifications - PendingNotifications with different data?
Let's say I have a background service that performs several tasks. As it completes task A, it posts notification A with a certain intent and some extra data that indicates viewing result of A. As it completes task B, it posts notification B with a certain intent and some extra data that indicates viewing result of B. As it completes task C, it posts notification C with a certain intent and some extra data that indicates viewing result of C. At the end, the notification area has three notifications. Each one has the same intent, except for one of the extra data fields. I would expect that each one would load my activity with different extra data. They don't. When onNewIntent is called, each has the extra data field set to C. I have rooted out any possible aliasing and checked the data as it is placed into a notification. It seems to allow only one set of data per package. Is what I am attempting not possible? Has anyone accomplished what I am attempting? For example, have you had a service download several large files, and then had notifications that would open each of those files? This is some of the relevant code: // post a finished notification. Notification finished = new Notification(R.drawable.notifier, tickerText, System.currentTimeMillis()); Intent intent = new Intent(); intent.setClass(DownloadService.this, MyActivity.class); intent.setAction(MyActivity.OPEN_LOCATION); // adding parameters to extras .. intent.putExtra(packageName.layer, layer); ... // The PendingIntent to launch our activity if the user selects this // notification PendingIntent contentIntent = PendingIntent.getActivity(DownloadService.this, 0, intent, PendingIntent.FLAG_ONE_SHOT | PendingIntent.FLAG_UPDATE_CURRENT | Intent.FILL_IN_DATA); String contentTitle = getString(R.string.n_download_completed); String contentText = getString(R.string.n_download_results, layer); finished.setLatestEventInfo(DownloadService.this, contentTitle, contentText, contentIntent); mNotificationManager.notify(finishedid++, finished); Nathan -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: On activity (re)usage en creation
Any thoughts on how bad the current behaviour is? Not sure what you mean - but if you haven't touched anything else, the current behavior is the default behavior, which should suffice for most apps. My point was, you're basically doing the equivalent of browsing a site. But for each click (as you go from an entry to its comments, to an entry), you start a new activity. Now i can imagine that for a browser you'd have an activity per tab, but not per page (as you have one superclass here, being page). This feels more efficient It is in this case easiest to make a separate activity for each type of page, but this means that while 'browsing' you're making a new activity for each click and that feels a bit redundant, expensive or.. well, something like that? I was wondering if it would be wise to make an effort to keep both pages in the same activity. -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: How can I know if OpenGl has drawn something?
Hmm.. I'm sorry but this has reached the limit of what I know off-
hand. I'd have to get into debugging your code to be able to help
more.
I have a feeling one of two things is wrong:
1) Your projection matrix is not matching what glOrthof is doing (fix
by using glLoadMatrix there)
2) Something is happening to your modelview matrix later that I can't
see from your code snippet and remappedRotationMatrix no longer
matches it.
Sorry I can't help more. All I know is that if your Camera space is
wrong from what you think it should be, you will face nothing but
problems trying to do visibility tests or picking. I do 3D visibility
testing of objects by creating frustum bounds and testing against
object bounding boxes - this is all in world space. I actually don't
need unproject to figure out what you touched because for me, it's
just a matter of making a segment from the near plane to the far at
the percentage distance from the sides in the viewport to your touch
point used on the near/far planes.
If you debug my suggestions 1 and 2 and come up with nothing, perhaps
there is an alternative way to check without still checking for drawn
pixels (which makes me shudder.)

Robert, first of all thanks for your time and kindness. The problem
for me is not drawing my scene. In fact, the scene is done. I'm going
to try being more explicit:
First of all, I set the projection matrix with:
near_height = 1;
zNear = 1;
zFar = 100;
window_height = height;
window_width = width;
gl.glViewport(0, 0, width, height); //Reset The Current Viewport
gl.glMatrixMode(GL10.GL_PROJECTION); //Select The Projection Matrix
gl.glLoadIdentity(); //Reset The
Projection Matrix
ratio = (float) width / height;
Matrix.orthoM(orthoProjectionMatrix, 0, -near_height * ratio,
near_height * ratio, -near_height, near_height, zNear, zFar); //I get
the Projection Matrix here
gl.glOrthof(-near_height * ratio, near_height * ratio, -near_height,
near_height, zNear, zFar);
Later, I get the rotation matrix and remap it with the lines:
SensorManager.getRotationMatrix(rotationMatrix, null,
mAccelerometerValues, mMagneticValues);
SensorManager.remapCoordinateSystem(rotationMatrix,
SensorManager.AXIS_Y, SensorManager.AXIS_MINUS_X,
remappedRotationMatrix);
gl.glMatrixMode(GL10.GL_MODELVIEW);
gl.glClear(GL10.GL_COLOR_BUFFER_BIT | GL10.GL_DEPTH_BUFFER_BIT);
gl.glLoadIdentity(); //Reset The Current
Modelview Matrix
gl.glLoadMatrixf(remappedRotationMatrix, 0);
Then, I draw all wich I want. Don't worry about the ray, it is well
done. I followed this page instructions http://www.opengl.org/
resources/faq/technical/selection.htm. I use glPushMatrix and
glPopMatrix, but as you can think it is not necessary. I have the
modelview untouched in remappedRotationMatrix.
My problem: Once I have finished drawing objects, I want to know if
there is some of them painted in the screen when I point an exact
place with the phone. I'm OK to choose an only one object if it is so
easier. With the next instruction:
GLU.gluProject(pos3DdelPuntoInteres[0], pos3DdelPuntoInteres[1],
pos3DdelPuntoInteres[2], remappedRotationMatrix, 0,
orthoProjectionMatrix, 0,new int[] {0,0,window_width,window_height},
0, prueba, 0);
I should get the screen coords of the pos3DdelPuntoInteres vector in
the prueba one. But if I see it with a Log, I can't deduce any
connection between this values and the screen. In the poing signed by
pos3DdelPuntoInteres there is an icon, if I move the phone so place
the icon in the upper left corner, then the first coord of prueba is
0, but no one else. In fact, it is impossible get an 0,0 position in
prueba.
Alternatively, I've found that if I multiply the modelview by
pos3DdelPuntoInteres, one of the components of prueba takes values
from 1 to -1 if the icon is displayed on the screen and out of this
range if not. The problem is that this value only refers to the x axis
of the screen and not to the y one. The others two values of prueba
seems to refer the angle of the yaw. Knows someone about a way of
calculate the position of the y axis like with de x ones using the
modelview matrix, so I can control if the object is on the screen?
Thanks.

[android-developers] Service stops works after 30 minutes when Android is turned off (trickles every 30 minutes for 5 minutes)
Dear forum, I wrote a service which continuously reports data to a remote server via HTTP. As a service should do it keeps working even when the Android is turned off (by a short press on the power button) and is not powered externally. This works fine on a Motorola Milestone (Android 2.1) until the battery holds but not on neither HTC Tattoo nor HTC Magic (both Android 1.6). On the 1.6 devices the service stops working after about 30 minutes for 30 minutes. Then it seems to work for 5 minutes again and stops again for 30 minutes and so on. I seems that there is some (undocumented?) power management acting which prevents to keep the Android running continuously when softly turned off. When I press a button and turn off again the service is working immediately for 30 minutes and the trickles starts again as described above. My questions are: 1) Is this behavior documented? 3) Is this special for Android 1.6 or just for HTC devices 4) How to turn off this feature?

05-10 15:03:48.658: INFO/TestRunner(748):
java.lang.UnsupportedOperationException: Can't convert to dimension:
type=0x2
From the call stack I can see that this line causes the crash:
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
this.setContentView(R.layout.my_layout);
}
Any idea?

[android-developers] Problem installing your own developed app
Hi all! I m trying to understand the different ways you can install your app on your device. It's clear for me that we have to use the .apk file and the command adb install packagename. One of my question is which is the difference between an unsigned app and a signed one? Other doubt is related with eclipse commands. When you run your app into a real device, are you installing it?and when you are debugging?i would like to clear these concepts: 1.- run your app with eclipse plugin is the same that execute the command adb install package name 2.- Which the difference between debug and run an app if the result is the same: install it on your device I have been developing an app and i have used the command run the app into a real device many times to see the results and i have had no problem but now i finished the app i want the .apk file and install it through the command adb but i get the next error: C:\adb install C:\myapp\ConexionWebcam.apk 775 KB/s (12400 bytes in 0.015s) scandir: Permission denied cannot create /sys/module/yaffs/parameters/yaffs_auto_checkpoint: permission den ied Can't dispatch DDM chunk 46454154: no handler defined Can't dispatch DDM chunk 4d505251: no handler defined pkg: /data/local/tmp/ConexionWebcam.apk Failure [INSTALL_PARSE_FAILED_NO_CERTIFICATES] Please help me because i have no idea what the meaning of this errors.

[android-developers] Nexus one gps issue
Hi,
I am working app for nexus one which uses gps. I have placed turning
on code of gps in onStart() of Activity and and turning off code in
onStop(). As per logs On/Off works fine specially turning off. But
then gps icon stays forever on notification bar. Is there any bug/
issue with Nexus One GPS? or am I doing anything wrong?
Tunrning on/ off code is as follows
onStart(){
...
String[] providers = { LocationManager.GPS_PROVIDER,
LocationManager.NETWORK_PROVIDER };
int noOfProviders = providers.length;
for (int i = 0; i noOfProviders; i++) {
final String currentProvider = providers[i];
if
(locManager.isProviderEnabled(currentProvider)) {
locManager.requestLocationUpdates(currentProvider, 100L, 0.0f,
_instance);
}
}
...
}
onStop(){
...
if (locManager != null) {
locManager.removeUpdates(_instance);
}
...
}
and the logs for turning off gps are..
LocationManager( 369): removeUpdates: listener =
com.xxx.xxx@4495e330
D/NetworkLocationProvider( 76): removeListener(): com.xxx.xxx
D/GpsLocationProvider( 76): stopNavigating

[android-developers] ServiceConnectionLeaked Error
My app meet a ServiceConnectionLeaked Error:
E ActivityThread: android.app.ServiceConnectionLeaked: Activity com.my
has leaked ServiceConnection com.m...@463dc0a0 that was originally bound
here
My app are two part, UI and service, Like music playback, the service will
always running, until user press UI Stop button.
If user press back button, make the UI destory, the service should still
run.
So, I check the Service status, if the service state is not STOPPED, now
playback, then do not unbindService (prevent service be stopped.) but I
receive this ServiceConnectionLeaked.
public void onDestroy() {
if (mMyManager.getStatus() == MyService.STATE_STOPPED) {
if (null != mMyConnection) {
unbindService(mMyConnection);
this.stopService(mMyServiceIntent);
mMyConnection = null;
}
} else {
Log.d(TAG, Service is run do nothing.);
}
super.onDestroy();
}
What the rigth solution?
Thanks
Ming.

[android-developers] someone please help me with these issues.
1. I am using a Broadcast Receiver which acquires a static WakeLock, then immediately starts an activity which starts a media player instance inside its onCreate, at the last line of OnCreate i have released the static wakelock which i had acquired in the BroadCastReceiver. Everything seems to work fine, except for the fact that the screen does wakeup but is locked and has to be manually unlocked before the user can see my activity, though the media player starts playing normally before itself. I have set lockStatic=mgr.newWakeLock(PowerManager.FULL_WAKE_LOCK| PowerManager.ACQUIRE_CAUSES_WAKEUP, LOCK_NAME_STATIC); still the screen has to be manually unlocked before the user can see the activity. Any workaround? 2. I have used an EditText inside a tablelayout, tablerow and have set the android:height and width to wrap_content, but still when i type on the softkeypad it exceeds the bounds of the EditText Box and overflows the screen too. have tried various properties on the EditText but none of them seems to work. 3. I have an Activity a ListView Activity which populates the List from a db. When the user clicks on an item in a list, i take him to a new Activity from where he can also delete the item he selected. The problem is that the Parent Activity's ListView is not refreshed and continues showing redundant content, when i have finished the child activity. I have tried making the cursor as static and calling cursor.requery() from my child activity before i finish it, but it doesnt seem to fix the issue. 4. I have used an Activity say activityA which sets up alarm using AlarmManager.set to a Receiver say RecA. If i want to cancel this alarm later from an Activity say ActivityB how do i do so? Somone please respond to the above issues soon. I have been trying a few workaounds since past few days, but am not able to fix these issues.

Re: [android-developers] Re: How to disable home and other buttons so as to persist an app?
Hi, Thanks Mr Romain Guy, for the information. @Mike dg : The requirement is that one app has to be loaded at startup which displays a browser with a specified URL. And one of the requirement is that whatever buttons the user presses or clicks, the browser shouldn't exit. The browser with the specified URL should be the only app that the user has access to. Since the 'Home' button on being pressed, exists the application, the above requirement can't be implemented.

[android-developers] Multi Touch - Does anyone know how it works
Ok So I've gone through several tutorials on the web. I understand how
the pointerCount works , I can get two points, etc, etc. My problem is
I am trying to implement a game control, i.e. dpad and some buttons.
The buttons are actually TextView objects with images. I Implement
OnTouchListener Interface. my onTouch Method gets called when it
should. The problem is if I have finger #1 on button a then press
finger #2 on button b my OnTouch() method is called with the view of
button a, not button b. Fine then I will just get the bounds of the
buttons and see if they intersect with the points clicked. No luck, It
seems as though the points that come in the MotionEvent are not
relative to 0,0 , but to some other coordinate system. I would have
thought all points were relative to upper left of screen. Here is my
code.
protected void onFinishInflate()
{
dpadView = findViewById(R.id.dpad);
dpadView.setOnTouchListener(this);
aButton = (TextView)findViewById(R.id.a_button);
aButton.setOnTouchListener(this);
bButton = (TextView)findViewById(R.id.b_button);
bButton.setOnTouchListener(this);
}
public boolean onTouch(View v, MotionEvent event)
{
// Dump touch event to log
// V.getId() is always equal to what the 1st finger is
pressed on!
Log.d(Controller,id: +v.getId());
dumpEvent(event);
if(buttonHit(event,v))
{
}
return true; // indicate event was handled
}
private boolean buttonHit(MotionEvent event, View view)
{
for(int i=0;ievent.getPointerCount();i++)
{
int pointerId = event.getPointerId(i);
int pointerX = (int)event.getX(pointerId);
int pointerY = (int)event.getY(pointerId);
Rect rect = new Rect();
view.getGlobalVisibleRect(rect);
//view.getGlobalVisibleRect(rect);
view.setBackgroundColor(Color.BLACK);
Log.d(Controller, pointer ( + pointerX + , +
pointerY + ) );
Log.d(Controller, bounds [( + rect.left + , +
rect.top + )-( + rect.right + , +
rect.bottom + )]);
if( rect.contains(pointerX, pointerY))
{
view.setBackgroundColor(Color.CYAN);
Log.d(Controller,Hit button);
view.performHapticFeedback(HapticFeedbackConstants.VIRTUAL_KEY);
return true;
}
}
return false;
}
I saw some posts from Romain Guy on Stack Overflow that said you can
just add on OnTouchListener to each Button but when I do so I do not
get a second event. Has anyone done this? Is there an example
somewhere?

[android-developers] Re: Multi Touch - Does anyone know how it works
No you cant just add onTouch to each button. The way multitouch is
designed it will only work inside one view. You will need to draw
everything yourself - you cant use multitouch over multiple view
objects. It only works inside one View. Create a big view covering the
screen, draw the contents yourself, and you can then get multitouch
positions accurately.
I know it sucks, right? I complained about it originally too but they
didnt agree with me...

Re: [android-developers] Multiple Notifications - PendingNotifications with different data?
Nathan wrote: Let's say I have a background service that performs several tasks. As it completes task A, it posts notification A with a certain intent and some extra data that indicates viewing result of A. As it completes task B, it posts notification B with a certain intent and some extra data that indicates viewing result of B. As it completes task C, it posts notification C with a certain intent and some extra data that indicates viewing result of C. At the end, the notification area has three notifications. Each one has the same intent, except for one of the extra data fields. I would expect that each one would load my activity with different extra data. They don't. PendingIntent.getActivity() will return a unique PendingIntent object *only* if the Intent you supply to that call is materially different than those used by other outstanding PendingIntents. By materially different, I mean where Intent#filterEquals() returns false. In your case, your three Intents are all the same from the perspective of filterEquals(), because filterEquals() does not take extras into account. Hence, you need to make three more distinct Intents. If your intents right now are using the component (e.g., new Intent(this, SomeActivity.class)), the easy way to do this is to assign some unique action string to them. That won't affect how the Intent gets routed, but it will make it distinct from a filterEquals() standpoint. -- Mark Murphy (a Commons Guy) http://commonsware.com | http://github.com/commonsguy http://commonsware.com/blog | http://twitter.com/commonsguy Android Online Training: 21-25 June 2010: http://onlc.com -- You received this message because you are subscribed to the Google Groups Android Developers group.

Now in this case my application does not start and it says preview error. So, is there any broadcast message / notification available which i can use over here.

[android-developers] Re: PNG quality in WebView based app
Wow! That must have driven you nuts trying to figure that one out. What provider were you using? Did you write a simple servlet or something that would serve the file as application/octet-stream?

Turns out it was not the webview, it was my provider : When browsing the web on gprs or edge my provider downgrades image quality on their server so that its a lot lighter to download on their network. When I tried over wifi everything came back to normal. In the end I implemented a regular binary file download from my server, and then displayed that image.

Is there anyway to prevent it from doing this? I don't want the image to lose any of its quality.

[android-developers] MediaPlayer pause on loop
Hi all, I am having an issue with a looping audio file using MediaPlayer. I am developing a realtime game and have a 100K MP3 file I want to loop as background music. The size of the file means I can't pre-load into memory (using SoundPool) so I am using the MediaPlayer to stream the data. All works fine, however if I set the stream to loop (MediaPlayer#setLooping(true)) when the stream gets to the end and MediaPlayer loops, I get a distinct pause in gameplay. Everything seems to hang for a good chunk of time (~100ms) presumably while MediaPlayer re-seeks to the start of the audio file, and this is killing my framerate and making the game unplayable at these points. There doesn't seem to be a way to configure any memory buffers etc on the MediaPlayer, so I'm wondering if I am using the wrong approach? Any other ways to run continuous background music?

So the process goes like this:
1. In your manifest file, make a activity and a receiver. Mention your
receiver class name here.
2. Make a entry for uses-permission android:name =
android.permission.RECEIVE_SMS
3. To test on emulator, test by DDMS perspective view.
4. You application will receive SMS while its dead too. in
Onreceive(), read the SMS and do whatever you want. you can also start
your activity from here.

[android-developers] Need your expertise on Tab control
Hello, My app's main screen consists of 5 tabs. First Second Tabs have integrated the same ListActivity , because both displays similar data(List of - images, text etc..). Each time I click on those 2 tabs, it should refresh the image list dynamically based on some condition. Now my question is, where should I create the ListAdapter exactly and update the ListAdapter with the new data(image, text etc..) on each tab(First Second tab)? Is it in onCreate() OR onStart() OR onResume() ? As per the flow, onCreate() / onStart() are being called only very first time, and after that, only onResume() is being called. Please need your guidance Thank you so much.. Regards, DK -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Multiple Notifications - PendingIntents with different data?
Let's say I have a background service that performs several tasks. As it completes task A, it posts notification A with a certain intent and some extra data that indicates viewing result of A. As it completes task B, it posts notification B with a certain intent and some extra data that indicates viewing result of B. As it completes task C, it posts notification C with a certain intent and some extra data that indicates viewing result of C. At the end, the notification area has three notifications. Each one has the same intent, except for one of the extra data fields. I would expect that each one would load my activity with different extra data. They don't. When onNewIntent is called, each has the extra data field set to C. I have rooted out any possible aliasing and checked the data as it is placed into a notification. It seems to allow only one set of data per package. Is what I am attempting not possible? Has anyone accomplished what I am attempting? For example, have you had a service download several large files, and then had notifications that would open each of those files? This is some of the relevant code: // post a finished notification. Notification finished = new Notification(R.drawable.notifier, tickerText, System.currentTimeMillis()); Intent intent = new Intent(); intent.setClass(DownloadService.this, MyActivity.class); intent.setAction(MyActivity.OPEN_LOCATION); // adding parameters to extras .. intent.putExtra(packageName.layer, layer); ... // The PendingIntent to launch our activity if the user selects this // notification PendingIntent contentIntent = PendingIntent.getActivity(DownloadService.this, 0, intent, PendingIntent.FLAG_ONE_SHOT | PendingIntent.FLAG_UPDATE_CURRENT | Intent.FILL_IN_DATA); String contentTitle = getString(R.string.n_download_completed); String contentText = getString(R.string.n_download_results, layer); finished.setLatestEventInfo(DownloadService.this, contentTitle, contentText, contentIntent); mNotificationManager.notify(finishedid++, finished); Nathan -- You received this message because you are subscribed to the Google Groups Android Developers group.

Re: [android-developers] Re: Multi Touch - Does anyone know how it works
Do you guys know if this is why the bug that many game developers have come
across occurs.. where trying to simulate two joysticks on the screen wont
work due to wrong touch info being consumed? I forget the details, but I
think it had to do with if you touch one point, and while doing so, touch
another..that works fine.. but if you release point 1, then touch again, it
some how reads as point 2, instead of point 1? Was this issue resolved due
to what you said above niko.. that multi-touch only works within one view? I
would have thought a game would use a single view as well tho.

Ok So I've gone through several tutorials on the web. I understand how
the pointerCount works , I can get two points, etc, etc. My problem is
I am trying to implement a game control, i.e. dpad and some buttons.
The buttons are actually TextView objects with images. I Implement
OnTouchListener Interface. my onTouch Method gets called when it
should. The problem is if I have finger #1 on button a then press
finger #2 on button b my OnTouch() method is called with the view of
button a, not button b. Fine then I will just get the bounds of the
buttons and see if they intersect with the points clicked. No luck, It
seems as though the points that come in the MotionEvent are not
relative to 0,0 , but to some other coordinate system. I would have
thought all points were relative to upper left of screen. Here is my
code.
protected void onFinishInflate()
{
dpadView = findViewById(R.id.dpad);
dpadView.setOnTouchListener(this);
aButton = (TextView)findViewById(R.id.a_button);
aButton.setOnTouchListener(this);
bButton = (TextView)findViewById(R.id.b_button);
bButton.setOnTouchListener(this);
}
public boolean onTouch(View v, MotionEvent event)
{
// Dump touch event to log
// V.getId() is always equal to what the 1st finger is
pressed on!
Log.d(Controller,id: +v.getId());
dumpEvent(event);
if(buttonHit(event,v))
{
}
return true; // indicate event was handled
}
private boolean buttonHit(MotionEvent event, View view)
{
for(int i=0;ievent.getPointerCount();i++)
{
int pointerId = event.getPointerId(i);
int pointerX = (int)event.getX(pointerId);
int pointerY = (int)event.getY(pointerId);
Rect rect = new Rect();
view.getGlobalVisibleRect(rect);
//view.getGlobalVisibleRect(rect);
view.setBackgroundColor(Color.BLACK);
Log.d(Controller, pointer ( + pointerX + , +
pointerY + ) );
Log.d(Controller, bounds [( + rect.left + , +
rect.top + )-( + rect.right + , +
rect.bottom + )]);
if( rect.contains(pointerX, pointerY))
{
view.setBackgroundColor(Color.CYAN);
Log.d(Controller,Hit button);
view.performHapticFeedback(HapticFeedbackConstants.VIRTUAL_KEY);
return true;
}
}
return false;
}
I saw some posts from Romain Guy on Stack Overflow that said you can
just add on OnTouchListener to each Button but when I do so I do not
get a second event. Has anyone done this? Is there an example
somewhere?

[android-developers] Re: Nexus one gps issue
You probably do NOT want to put the starting and stopping of the
location (GPS) providers in the onStart() and onStop().
The onStop() may not be called when your activity goes to the
background:
- It is not called because your activity remains active in the
background
- It is not called because the OS just killed your entire process.
(this would actually kill the GPS provider as well).
Instead, start and stop the GPS provider in the onResume() and
onPause().

That won't work. What you want to do is not possible unless you create your own ActivityManager allowing just one activity: your activity. I guess you have to create your own AOSP branch for this to happen. All apps play by the same rules. And what if the user gets a phone call? What if a SMS comes in? What if not only your app wants to be displayed all the time, but another app wants to be displayed all the time as well?

I was wondering if it would be wise to make an effort to keep both pages in the same activity. If you're dealing with actual links and web pages, then yeah, it makes more sense to have a WebView or something where only the current page changes and not create a new activity. If you're using buttons or something else and building a standalone app that pulls in data, then rethink having a button on the details page of comment that takes you back to other entries. Or, again, playing with the flags that you use to launch the activities (like using singleTask) will force them to be re-used instead of creating new ones.

[android-developers] Power-loss semantics of SQlite on Android
Hello,
I have an app that stores a database on SD card.
If I don't use beginTransaction/endTransaction, does Android have any
guarantee about the the contents of a database when power is lost? For
example, if I have code like this:
//db.beginTransaction();
//try {
db.delete(TABLE_NAME, id=123, null);
System.out.println(Deleted 123);
db.delete(TABLE_NAME, id=456, null);
System.out.println(Deleted 456);
//db.setTransactionSuccessful();
//} finally {
// db.endTransaction();
//}
and the database is in SD card.
When I randomly pull the SD card from the phone, is any of the
following guaranteed to be true if I insert the SD card again and
reload the database:
(1) Order of deletion -- if id=456 has been deleted, then id=123 must
have been deleted.
(2) Immediacy of commit -- if I see the message Deleted 123 from
logcat, then id=123 must have been deleted.
(3) Non corruption -- rows that are unrelated to id=123 and id=456 are
guaranteed to remain in the database regardless
Note that I am not using transactions because I don't need the two
rows to be atomically deleted. However, I do not want the user has any
surprises -- if I tell them a row has been deleted, then this row
should not appear again when the user re-inserts the SD card.
Thanks!

On Tue, May 11, 2010 at 4:06 AM, Federico Paolinelli fedep...@gmail.comwrote: I found myself using the same code for accessing to gps / cell location stuff from a couple of activities of my application. Yup, it happens. What I was wondering now is, which is the best way to avoid code duplication? Don't duplicate code? =P No, seriously, as soon as you find yourself copying and pasting - stop. You're doing something wrong. Take all that copy - pasted code and study it. Determine what it does, how it does, and what the variables are (if any). All the duplicated stuff should go in one central location. How that is structured will largely depend on your app and your coding style. Should I use a superclass for the activities which implements that kind of stuff? Use an helper class? Because of the way Android is structured, I find that helper classes make more sense then super classes. For example, you can't really have a base activity class that centralizes all common activity functionality, since some activities have to extend List-, ExpandableList-, or Map- activity, for example. You can however have a helper class that each Activity has as a member which they forward their common functionality to. How do you deal with this kind of problems? Create a helper class, sometimes static if it makes sense, that does the work you find yourself copying and pasting. For GPS, for example, I have a class that takes care of starting and stopping the GPS funtionality, keeps track of the current location, can return it in various forms (coordinates, named location, etc), notifies of location updates, and handles other related tasks. Each activity that requires it just instantiates it with the proper parameters (provider, criteria, frequency, etc), calls start and stop as necessary, and lets the class handle the rest. - TreKing - Chicago transit tracking app for Android-powered devices http://sites.google.com/site/rezmobileapps/treking -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Can not create service interface
Hi, For some reason I can not create an AIDL service interface, no matter how simple it is. I am using the latest version of eclipse. This is what I get, no matter what service functions I add to the aidl file: The method attachInterface(IInterface, String) in the type Binder is not applicable for the arguments (MyServiceInterface.Stub, String) MyServiceInterface.java The generated file MyServiceInterface.java, contains numerous errors. Among them is testapp.test.net cannot be resolved to a type. Very strange, since eclipse can do this for everything else. I have other projects in my workspace where I use AIDL successfully, but now I can not add this to any project. Very strange. If remove the aidl file, I can compile and run the app without any problem. Anyone that have any idea what is going on here?

[android-developers] shouldOverrideUrlLoading not getting called for file:///android_asset links
I am using WebView to display web content in my app. Since I want to keep all content in my webview and not launch the browser, I override shouldOverrideUrlLoading and call loadUrl(). One of the pages has an image that is very large, so I want to put it in the assets directory. When the user clicks on a link that starts with http:// everything works fine. When they click on a link that starts with file:///android_asset, shouldOverrideUrlLoading never gets called so my app never calls loadUrl - hence nothing happens. Anyone know why this is?

[android-developers] Re: Spurious calls to onPause?
For whatever it's worth, this continues to happen. It seems to happen faster and more frequently if I'm running in the debugger, but it happens fairly often under all circumstances. I've had to move all my onPause code to onStop, which is not optimal but it's the only thing that works. I'm running on Cupcake, and my impression is that Cupcake is simply not done - there are lots of things that just flat out don't work (e.g. this problem, RelativeLayout, route add, Thread.isInterrupted, etc). In many cases we've debugged into the system code and found the bugs that cause the problems. Can anyone comment on how true this is of more current builds?

If I don't use beginTransaction/endTransaction, does Android have any
guarantee about the the contents of a database when power is lost? For
example, if I have code like this:
//db.beginTransaction();
//try {
db.delete(TABLE_NAME, id=123, null);
System.out.println(Deleted 123);
db.delete(TABLE_NAME, id=456, null);
System.out.println(Deleted 456);
//db.setTransactionSuccessful();
//} finally {
// db.endTransaction();
//}
and the database is in SD card.
When I randomly pull the SD card from the phone, is any of the
following guaranteed to be true if I insert the SD card again and
reload the database:
(1) Order of deletion -- if id=456 has been deleted, then id=123 must
have been deleted.
(2) Immediacy of commit -- if I see the message Deleted 123 from
logcat, then id=123 must have been deleted.
(3) Non corruption -- rows that are unrelated to id=123 and id=456 are
guaranteed to remain in the database regardless
Note that I am not using transactions because I don't need the two
rows to be atomically deleted. However, I do not want the user has any
surprises -- if I tell them a row has been deleted, then this row
should not appear again when the user re-inserts the SD card.

[android-developers] Re: drawable-hdpi not appearing in eclipse emulator
This is from the Android Dev Guide http://developer.android.com/guide/ practices/screens_support.html Pre-scaling of resources (such as image assets) For example, if the current screen's density is high, the platform loads resources that are tagged with the qualifier hdpi and uses them without scaling. If no such resources are available, the platform uses the default resources instead, scaling them from the baseline density (medium) to high. This is what I based my question off of. Here it says as long as I have the hdpi qualifier, it will automatically choose images from that folder for a high density screen. Is this not correct or am I missing something? I could always hard code statements to check the current screens density and preload the PNG graphics that correspond to it. I am just curious if this actually works. The upscaling of the graphics work, but not the automatic qualifier choosing.

[android-developers] External allocation too large for this process OutOfMemoryException
OK, so I've done some searching, seen others hit this problem but never really saw a solid resolution. I have a situation where I am loading large-ish images (~120KB jpg) from a remote webserver and displaying them to users in a gallery view. Now these images take a bit of time to download, so I would like to cache them. So I stick the bitmap in a hashmap of softreferences inside a static manager class. I know the usual culprit here is that the programmer is leaking memory. But this is the same approach (soft references, hashmap) that JBQ takes in his shelves app, and I really don't think I'm keeping any more references to the bitmap than the one soft reference. So I don't think leaking is the problem, although if someone who knows better insists that I probably made some mistake, I'll revisit this. And yes I know my images are too large, make them smaller, but really I want an image larger than the screen so users can zoom and pan around inside the image. If you want to tell me that's not a function Android can support, then I am at a loss for words. So my app gets an External allocation too large message on logcat. It only happens after I run the program for a long time. I see finalize() methods being called on my Image derivative objects, I also see many of the softreference entries going to null inside my hashmap, so I suspect that my cache is operating correctly, although I am not sure how timely the actual bitmaps are being GCed, but I see GC messages saying ~900KB freed, which I can't see coming from anywhere else in my app. So I have three main questions that I can't find the answer to in similar past threads: 1. I've seen recommendation on calling recycle() on bitmaps. But given the fact that I want to keep the bitmap in softreferencecache to keep the app responsive, I don't really know when the softreference goes invalid to call recycle. If the GC runs and clears the softreference that is the only remaining reference to the bitmap, is that as good as calling the recycle on the bitmap, or not necessarily? 2. Is there a way I can manually keep my memory usage down right before bitmap decoding is going to need to work? I see ways to see if the system is in low memory state. But I don't care about that, I need to know about my own dalvik process. How can I estimate whether I have the 1228800 bytes to decode the uncompressed image. Because I know every time I'm about to allocate the image, is there a recommended way to detect issues, and is there a way to force the GC to successfully clean up? I only display one image at a time, although it's possible that the BaseAdapter has more widgets created than just the one being displayed (but I don't suspect that it has that many views holding references to the bitmaps, it does recycle views after all). I see that one Dalvik VM API is deprecated and going internal. What's left for me to use? 3. LAST RESORT: If it's impossible to get Dalvik to stay at a low memory usage. Then I suppose I need to stop caching my bitmaps in a hashmap. In which case I'm going to write them to storage (yuck). I don't want to pollute their SD card, and I don't want them to see the app cache consuming some of their precious ~90MB of usable internal space. Is there an application lifecycle hook that I can hook into to clear up my file cache? I don't want to delete stuff as soon as an Activity goes into the background because they might go right back, I want to hook into when my entire application hasn't done anything in the while and Android low memory kills it. Then I have a minor question: 1. In JBQ's shelves application I see he switches between decoding with SKIA which he uses BitmapFactory.decodeStream and BitmapFactory.decodeByteArray, I didn't realize that one was different. Is SKIA bad? How should we as developers know this? Thanks in advance. -Eric -- You received this message because you are subscribed to the Google Groups Android Developers group.

I've been trying everything I can think of to find some kind of workaround, but so far have failed to do so. It would be great to get a response from one of the Google engineers on this and I think it would hopefully at least put the issue to rest, even if the response is that they do not plan to change this going forward. I hope that is not the answer, but at least we would know. The odd thing is that thesensorsappear to behave somewhat differently depending on the actual device. For example, there are different behaviors between the Droid and the Nexus One, despite the fact that they are both using Android 2.1. So possibly some of the issues are related to the variations in the hardwaresensors themselves, but that is just more speculation. Dianne, if you are out there, I think there are a lot of people that would like to get a response on this one. Thank you!!

Can this be confirmed? I have gotten around this by using a wake lock, but this is a much less than ideal solution as it drains a lot of battery. If the accelerometer was disabled in low power mode to save the battery, it may very well have the opposite effect in many cases, such as mine. A partial wake lock seems to be required to keep it running, which is obviously much worse than if just the accelerometer were running without the need for the wake lock. Are there any other workarounds anyone knows of to getting accelerometer values while the phone is in low power mode? Also, are there any plans to change this in future versions of the OS? If there are no plans to change this, I would definitely like to petition for this to be changed. Thoughts? Ideas? Workarounds?

[android-developers] Upgrading 2009 I/O device from Donut (1.6) to Eclair (2.0/2.1)?
I have periodically attempted to search for information about this, but never really got to the bottom of it. Are there any instructions online for upgrading the 2009 I/O device from Donut (1.6) to Eclair (2.0/2.1)? I successfully updated from Cupcake (1.5) to Donut (1.6), but every time I have tried to find information on the next upgrade I have not seen anything online. What am I missing? For I/O 2010 you need Eclair to view the conference application from any Android device, which is a little frustrating All help appreciated. I have an inkling that this is a little like a if you can't figure it out yourself then you shouldn't be using it sort of setup... hopefully I am wrong about that.
