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<ResolveInfo> 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!
