[android-developers] Re: resolution problem!
That's a simple problem of variable scoping. Reference the outer
EditText by using this.name or rename the variables.

[android-developers] MediaPlayer sound problem
Hello.
I have this task:
Need to play short (0.3-0.4 sec) sounds all the time. When sound is
played, it should start again, etc. User can press button to reset
sound - it should stop and lunch.
I did many tests. I tried to create 1 MediaPlayer, then do this:
MediaPlayer.OnCompletionListener complListener = new
MediaPlayer.OnCompletionListener()
{
public void onCompletion(MediaPlayer mp) {
lunchSound(); // rewind
}
};
private boolean lunchSound()
{
try
{
mplayer.seekTo(0); // move to start
mplayer.start();
return true;
}catch(Exception e){}
return false;
}
When user press button, I call lunchSound();
It works great on emulator and on device if I have eclipse+debugger
on.
When I disconnect debugger, I have very strange errors - sound can
stop at all (till program restart), sound can start repeating (play
0.1-0.2 sec, then restart). Can someone please provide me some info
about problem?
Thanks.

[android-developers] Re: Audio streaming/progressive download over HTTP
what is more: according to media-formats.html in the reference, MPEG4 SP is not supported for both encoding and decoding, so how can it support streaming? quite confusing. On 4月23日, 上午7时59分, Dave Sparks davidspa...@android.com wrote: Progressive streaming using HTTP is well-supported. RTSP support isn't great yet, but it will get better with the 1.5 release (Cupcake), which fixes the 302 redirect problem. There may be some issues with RTSP and H.264 - we found some issues with the hardware codec late in the test cycle that we're too risky to fix. H. 263 and MPEG4-SP should work pretty well. The caveat with RTSP is that carriers may block the streams.

Could you please help me? 1. MediaPlayer supports progressive download according to the developer guide from this linkhttp://developer.android.com/guide/topics/media/index.html (If you're passing a URL to an online media file, the file must be capable of progressive download.). As far as I understand progressive download means media playback during download process with saving the media file to file system(SD card or internal FS) after the downloading is finished (if it's a file, not a stream in the passed URL). So, I tried to set the following URL: setDataSource (http://84.204.154.49/mmapi/music.mp3). Playback is fine, but the file isn't saved to SD card or internal phone file system. Can MediaPlayer save media content to the file system after downloading is completed? Is there a way to turn on such capability? 2. Does MediaPlayer support HTTPstreaming? I tried to usehttp://217.10.32.134:8129/ultrafan128.mp3,http://62.32.66.180:8800, also AMR-, AAC- audio stream over HTTP on the local server, but playback does not work. For example, RTSPstreamingworks fine with AMR and AAC.

[android-developers] Re: How to browse deeper into /data/data/package/app_somename/somedir
Hi, I think I found two answers to my own question: 1. The files and directories I wanted to see start with a dot (.) which are hidden by default on linux. Using adb shell, I can use ls - a to see them. Anyway, I can not see them in DDMS and I cannot find a setting to change that. I think I will file a bug report for that. 2. I've managed to write a simple directory browser activity in 67 lines of code. Only this way I found out that the files started with a dot. I anyone's interested, I can post that code, too.

I think this is a permission related problem, but I thought the usage of MODE_WORLD_WRITEABLE would solve this. I have no good understanding of what linux permissions mean, but drwxrwxrwx seems to me as if every user has every possible permission on that dir. Because I cannot see the files and subdirectories there in, I cannot tell if they are present and if they have the right permissions. If there is really a permission problem, I think I could get arround it if I rooted my phone. Do you think this would help?

[android-developers] Parsing XML feed with SAX
Hi,
I'm unable to consume a WS with the SAX, for some reason my
implementation doesn't read the complete XML feed, it reads it up to a
random point. Has anyone faced anything similiar? Here's what I'm
doing:
After calling a RESTful WS a read the response from the server as
follows:
if (isSessionActive){
HttpEntity entity = response.getEntity();
SAXParserFactory spFactory = SAXParserFactory.newInstance();
SAXParser saxParser = spFactory.newSAXParser();
XMLReader xmlReader = saxParser.getXMLReader();
eventsHandler = new EventsHandler();
xmlReader.setContentHandler(eventsHandler);
xmlReader.parse(new InputSource(entity.getContent()));
}
Where my EventsHandler.java is as follows:
public class EventsHandler extends DefaultHandler {
@Override
public void startDocument() throws SAXException {
}
@Override
public void endDocument() throws SAXException {
}
@Override
public void startElement(String namespaceURI, String localName,
String qName, Attributes atts) throws SAXException {
Log.i(this.toString(), + localName + );
}
@Override
public void endElement(String namespaceURI, String localName, String
qName) throws SAXException{
Log.i(this.toString(), / + localName + );
}
@Override
public void characters(char ch[], int start, int length){
}
}
Hope to get some feedback! Thanks.

[android-developers] Re: why there's no boot.img in Android-1.5
The kernel is lost. I traced the making log, and found boot image is generated based on ramdisk image kernel. So, boot image is not created successfully.

Finally, the G1 can not boot up at all. I miss something else? Or zImage can't be used as a kernel for G1 at all?

Hello all,
I have more than one notification in notifications area and each of

pending intent from the notifications, first intent is handled
correctly and the extras received successfully on the next(called)
activity. Nonetheless, if I go with the other notifications with
different extras, activity is resuming but rather than containing my
new extras it still has the first(old) values.
I played with the flags on intent but as far as I see notification is
always calling the intent with FLAG_ACTIVITY_NEW_TASK flag set. If I
do the same coding with Intent(rather than PendingIntent) everything
goes well.
Here is the code that I tried;
PendingIntent contentIntent =
PendingIntent.getActivity(this, 0,
new
Intent(Weather.GET_WEATHER_ACTION).
putExtra(package.prefix.tmp, 1).setFlags
(Intent.FLAG_ACTIVITY_NEW_TASK), 0);
try {
contentIntent.send();
} catch (CanceledException e) {
e.printStackTrace();
}
PendingIntent contentIntent =
PendingIntent.getActivity(this, 0,
new
Intent(Weather.GET_WEATHER_ACTION).
putExtra(package.prefix.tmp, 2).setFlags
(Intent.FLAG_ACTIVITY_NEW_TASK), 0);
try {
contentIntent.send();
} catch (CanceledException e) {
e.printStackTrace();
}
1 is received in first call but in the second call 1 is received again
rather than 2.
I think I am missing something on the life cycle of the PendingIntent,
any help/idea would be appreciated.

[android-developers] Re: Screen lock turns of the accelerometer.
Accelerometer does work under screen lock when the power is not dimmed. We debugged it in ddms on the real g1 device. Guess, if you can acquire a Power wake Lock, you should be able to read acceleration. We have not tried to acquire it in program, just manually. This was done on current android version, not cupcake release. D On Apr 20, 2:39 pm, Jordan Frank jordan.w.fr...@gmail.com wrote: Fixed in cupcake!

[android-developers] Re: Parsing XML feed with SAX
It isn't big at all, it's got about 25 elements, it's not not a very deep tree either. I've parsed way longer XML feeds in the past with the same implementation of SAX.

[android-developers] Re: Parsing XML feed with SAX
What happens when you add a println statement before the last line? Is this reached? Is startDocument() called and how do you know that endDocument() is not called? In the quoted code you're not doing anything. Also, is it a conscious decision to use SAX here? I think SAX is a pain for most ordinary cases, and when you have such a small document DOM might be ok for you. It probably wouldn't here as the DOM parser uses SAX to build the tree.

[android-developers] “The application xxxxxxxx (pr ocess xxxxxx) has stopped unexpectedly. Please try again.”
Hi there! For some reason I can't explain, when my app runs, I will on occasion get the following error message: “The application (process xx) has stopped unexpectedly. Please try again.” When I debug my code, it seems to break at random places that doesn't make sense. On top of that I tried to surround the entire code with a try/catch block just to try to catch the exception, but it doesn't work either. I'm suspecting it's the OS that is producing this error message but I don't know why. As far as my code goes, if there were exceptions caused by it, it would've been caught by the try/catch block. Can someone shed some light here? --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] distributing an app packaged with just emulator
Hi All, I was wondering if anyone has ever been able to distribute their app in a bundle with an emulator? The reason I want to do this is that I have some friends who don't have android phones, but I'd like them to be able to play with my app so that they can give me feedback. I've previously sent them screen casts, but I'd really like them to be able to get interactive with the app. Now I could ask them to get all installed with the whole android framework, eclipse etc,. but some of them are not so technical. Ideally what I'd like to be able to do is create a package that is the android emulator with my app and perhaps 1 or 2 other related apps pre- installed, so that they can download it, open it and run it interactively on their computers? Has anyone ever tried this? So far I found that I can run the emulator standalone, and I assume I could probably send them just that and it would run. However the adb tool is needed to install apps. I could send them that too, and ask the to run an 'adb install myapp.apk' from the command line, but at the moment I can't even seem to do that myself. Running the emulator standalone, the adb tool can't seem to see it: samuel-josephs-computer-2:tools samueljoseph$ sudo ./adb devices List of devices attached I just get no list of devices ... I have previously used the adb tool to install apk files, but that is after I had started the emulator from eclipse - of course even then I always have to restart eclipse and the emulator two or three times before I can get the connection (I am on OSX 10.5.6., eclipse 3.4.1) ... Any suggestions greatly appreciated. CHEERS SAM --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] What's this problem?
I have written a method, like this
private Bitmap getBitmapFromUrl(String urlString)
{
try {
URL url = new URL(urlString);
HttpURLConnection con = (HttpURLConnection)url.openConnection();
InputStream is = con.getInputStream();
Bitmap bmp = BitmapFactory.decodeStream(is);
return bmp;
}catch(Exception e)
{
return null;
}
};
When I call this method continuously in a thread, it returns a valid
bitmap only at the first call, as for the following call, LogCat would
report jpeg error 20 Improper call to JPEG library in state.
Actually, I think the problem is because of the connection error,
since when I debug the application, the inputstream seems invalid.
Is there anyone know what the problem is it?
Thanks in advance.

In the quoted code you're not doing anything. Yes, startDocument() gets called, endDocument() doesn't, I know that as I've logged it. Also, is it a conscious decision to use SAX here? I think SAX is a pain for most ordinary cases, and when you have such a small document DOM might be ok for you. It probably wouldn't here as the DOM parser uses SAX to build the tree. Yes, I've always thought SAX is somehow quicker. I guess I will just switch to DOM for that WS.

You will not hear the music again, but if you check the music process, you will find the music service restart and service is still alive and still occupy system resource.

Could you please help me? 1. MediaPlayer supports progressive download according to the developer guide from this linkhttp://developer.android.com/guide/topics/media/index.html (If you're passing a URL to an online media file, the file must be capable of progressive download.). As far as I understand progressive download means media playback during download process with saving the media file to file system(SD card or internal FS) after the downloading is finished (if it's a file, not a stream in the passed URL). So, I tried to set the following URL: setDataSource (http://84.204.154.49/mmapi/music.mp3). Playback is fine, but the file isn't saved to SD card or internal phone file system. Can MediaPlayer save media content to the file system after downloading is completed? Is there a way to turn on such capability? 2. Does MediaPlayer support HTTPstreaming? I tried to usehttp://217.10.32.134:8129/ultrafan128.mp3,http://62.32.66.180:8800, also AMR-, AAC- audio stream over HTTP on the local server, but playback does not work.

[android-developers] Re: PendingIntent problem
That said... I would be -very- suspicious about the code you posted where you are effectively creating random identities for your pending intents. In most of the places where one uses a pending intent, you give it to something that holds on to it indefinitely, so you need to be able to recover the previous pending intent so you can give it back to have it unregistered. That is why the API works the way it does. This API is really not intended to generate tons of pending intents whose lifetime is not being managed.

[android-developers] Re: AppWidget issues
So just a heads up that we won't be able to fix the onDeleted() bug
for the 1.5 SDK. Here is a quick workaround that you can patch
against your class that extends AppWidgetProvider to correctly catch
and handle the onDeleted() event.
@Override
public void onReceive(Context context, Intent intent) {
final String action = intent.getAction();
if (AppWidgetManager.ACTION_APPWIDGET_DELETED.equals(action)) {
final int appWidgetId = extras.getInt
(AppWidgetManager.EXTRA_APPWIDGET_ID,
AppWidgetManager.INVALID_APPWIDGET_ID);
if (appWidgetId != AppWidgetManager.INVALID_APPWIDGET_ID) {
this.onDeleted(context, new int[] { appWidgetId });
}
} else {
super.onReceive(context, intent);
}
}

Oops, you're right, thanks for catching that. For the example widgets
I've been writing that use configuration steps, I've been keeping an
internal CONFIGURED flag which I use to skip updates. Because I was
skipping non-configured widget updates, I never noticed this myself.
(I also used this flag to skip the first update before the
configuration step has been completed.)
Also, a quick update on the fixes: most of them will be delayed until
the next platform release because the device-bound code is already
frozen. We could fix it for the SDK, but it would be bad to have
different behavior between the two. We definitely have bugs filed for
these, and they will be fixed.
Thanks for digging in and finding them. :)

[android-developers] Re: Customer signature
btw, it might be lighter-weight to collect and package up the vector drawing instructions, instead of a heavy image. j On Thu, Apr 23, 2009 at 12:30 PM, dan raaka danra...@gmail.com wrote: There is no ready-to-use signature widget in android.

In my app, I need a customer signature for prooving the customer have seen some informations and validate them. - Does anybody knows the Android way for implementing a customer signature ? With Windows CE, we can use a signature's specific component, and the customer can use the pen to draw lines. But how can we do this with finger's like mobile phone ? It seems to be a very difficult question, and I haven't found an answer to my question yet.

[android-developers] Re: SharedPreferences got deleted! - What could be the problem?
Thank you for your responses. By the way I love Nubinews. :) It is a known bug that signs lead to a loss of shared prefs. But my settings don't include these signs. :( I have only the following things included as strings: content://media/internal/audio/media/33 100,200,300,400 So this can't be the problem with my settings loss. :( I will try using to quote the strings right now and I hope to fix the problems with that. My problem ist that I can't reproduce the bug on a daily basis. Often it works with the same settings for weeks and suddenly the prefs are gone.

[android-developers] Re: SharedPreferences got deleted! - What could be the problem?
I also saw the prefs being lost ocassionally, especially after update or reinstall. I haven't seen it happen (yet) after quoting, but maybe that's just luck. I will also add a call to setPersistent to my app see if that helps. On Thu, Apr 23, 2009 at 1:12 PM, scanning_it festival.s...@googlemail.comwrote: Thank you for your responses.
