I eventually found two spectacular ways to get the list of
applications on the phone (including the gallery). Both of these
methods are from Android source code!
Method one, if you want the list of applications in a list to iterate
through:
PackageManager manager = context.getPackageManager();
Intent mainIntent = new Intent(Intent.ACTION_MAIN, null);
mainIntent.addCategory(Intent.CATEGORY_LAUNCHER);
final List<ResolveInfo> apps = manager.queryIntentActivities
(mainIntent, 0);
Collections.sort(apps, new ResolveInfo.DisplayNameComparator
(manager))
if (apps != null) {
final int count = apps.size();
for (int i = 0; i < count; i++) {
ResolveInfo info = apps.get(i);
String packageName =
info.activityInfo.applicationInfo.packageName;
String activityName = info.activityInfo.name;
Drawable icon = info.activityInfo.loadIcon(manager);
}
}
Wow!
For the second method, in my case I needed the applications in a
pickable list. I was able to poach some code from googles Launcher to
do this, and it also works fast and amazing.
Intent mainIntent = new Intent
(Intent.ACTION_MAIN, null);
mainIntent.addCategory(Intent.CATEGORY_LAUNCHER);
Intent pickIntent = new Intent
(Intent.ACTION_PICK_ACTIVITY);
pickIntent.putExtra(Intent.EXTRA_INTENT, mainIntent);
startActivityForResult(pickIntent,
MoreIconsConstants.REQUEST_PICK_APPLICATION)
That will return in your onActivityResults method the intent for the
item that was picked!
Enjoy.
