[android-developers] Is there a way to start updating all apps in a row ?
For now, updating Android apps is a pain : you must go to the android market my download section (and not in the Manage Application system setting section, which is very counter intuitive), then scroll to each app needing an update, clic on it, run the update, and go back, then clic on the next one... I know that installing an app requires permissions, you can't do it programmatically without asking the user the permission. But is there a way to make a batch processing, like asking for the credentials once, and use it to update all the apps in a row. It would be pretty awesome to be able to code an Update manager, running in backgroup and notifying the user for updates so he can keep up regularly and quickly. Maybe it's in plan for Donut ? --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] List loading several times
I have a list containing a dozen of item, but takes a lot of time to process because each item has a lot of calculated data. On startup, I create the list once, using a custome ListAdapter while overloading the getView() method. But putting some Logs on getView, it seems that the list is created several time (the logs for the same item appear 2 or 3 times). All the code to create the list with the list adapter is in a method called in onResume, and nowhere else, so I can't figure why this is happening.

[android-developers] Updating an app make it appear twice !
I made a lot of changes to my app : databases scheme, graphics, code, etc. The biggest is the package name that I renamed to a total different one. The applicatgio got the same name and Id in the manifeste.xml file and the apk got the same name, with the same digital signature. Nevertheless, when using ./adb install -r myapp.apk, myapp appears twice in the menu. How can I prevent this from happening, and if I can't, how can I automate he migration ? I have several clues : prompting the user for uninstalling the old app, copying the database from the old file to the new one, etc. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Bluetooth sound output
Hello, I just noticed, using the HTC Dream that using a bluetooth headset was really easy for phone calls, but nothing seemed to be available for videos / music sound output. V1.0 limitations are not at fault since when you play a music and start a call, you can hear the music in the headset for a second. So it's technically possible, just not available in the settings. Does anybody knows how to redirect programatically the sound output to the blutooth headset ? I'd like to code a little app that let you listen to your music while looking like a total idiot with a big device hanging to your hear :-) Cheers ! --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Developers group.

android.app.ActivityThread.performLaunchActiv
I searched in the other posts something similar, and It seems that it
must be because the ImageButton is set to null.
Unfortunately I can't find anything that would lead to it in the XML
or the Java code. The button is displayed properly and eclipse does
not detect any error. I guess this is runtime.
I tried to cast from ImageButton to button but it doesn't change
anything. So I image the trouble is from findViewById(), but arrow to
exists, is a regular pgn file and is displayed by the emulator if this
line is commented.
The weirdest is that I got a similar statement just above, and I can't
see any difference.
Any clue ?

[android-developers] [SOLVED] Null pointer exception while using setOnClickListener
My row layout is in a separate XML. It appears that findViewById only
can find an inflated view.
To solve that, I think I will need to create a custom ListAdapter that
will bind an event to each button while inflating each view.
If you see any better way, let me know.
Cheers
