[android-developers] PackageManager.queryIntentActivities() returns incomplete list?
Hi there,
I am writing a launcher in Android and here is the problem I have been
trying to fix for a while with no luck.
I have below code to query all activities running at very beginning of
my launcher, say onResume().
final Intent mainIntent = new Intent(Intent.ACTION_MAIN, null);
mainIntent.addCategory(Intent.CATEGORY_LAUNCHER);
final List infos =
packageManager.queryIntentActivities(mainIntent, 0);
for (final ResolveInfo info : infos) {
// create my own record for each activity
}
The problem is that if I set my launcher as default and reboot the
device, every time I can get only part of the full list by above code.
It seems some big fat activities (such as Wind-up knight) are always
missing. However running above code second time will return the full
list. Does any one have idea why? My guess is that PackageManager
needs some time to parse the fat activities and if
queryIntentActivities() is called too early, it just returns a partial
list, is that true?
But why the default launcher has no such issue at all?
Thanks for any help in advance!

Ah, thanks a lot Dianne!
I do forget to handle ACTION_EXTERNAL_APPLICATIONS_AVAILABLE in my
code.

[android-developers] onConfigurationChanged() is not called when flipping between landscape and reverse landscape?
Hi there, On ICS, when I flip the phone between landscape and reverse landscape, it seems onConfigurationChanged() won't be called. How can I get notified when such event happens, or did I miss anything here?

[android-developers] Re: onConfigurationChanged() is not called when flipping between landscape and reverse landscape?
Thanks guys for your reply! I tried to set android:configChanges="keyboard|keyboardHidden|orientation|screenLayout|uiMode|screenSize|smallestScreenSize", but it didn't help. To Hoang, I can understand that Configuration does not change when I flip the phone. Actually I am calling getRotation() to decide current display rotation. The thing is that I need a trigger to call the method when orientation is changing between landscape and reverse landscape. And onConfigurationChanged() is my first thought. Any idea?

[android-developers] Re: onConfigurationChanged() is not called when flipping between landscape and reverse landscape?
I am using a rotation listener as work around for this, but that means my code has to be synced with framework in terms of orientation change (I mean landscape vs reverse landscape). In theory, that's an issue, isn't it. Hi Dianne, thanks for your reply! Actually I have a camera preview running when user flips the phone. In that case if I don't handle the camera rotation myself, all widgets are good except that preview is upside down. As Streets Of Bostom suggested, I can make it work by writing a rotation listener. Just want to ask is there any better, or official solution for this? Thanks in advance!
