Query all installed Launcher Applications


The tip for making this happen is that all launchers register these two categories in Manifest

+ CATEGORY_HOME

+ CATEGORY_DEFAULT

and this is my snippet to query ’em all.

	public static ArrayList<ApplicationInfo> getAllLaunchers(Context context) {
		// create new intent
		final Intent mainIntent = new Intent(Intent.ACTION_MAIN, null);
		// all launchers register these two categories
		mainIntent.addCategory(Intent.CATEGORY_HOME);
		mainIntent.addCategory(Intent.CATEGORY_DEFAULT);

		// query normally
		final ArrayList<ResolveInfo> pkgAppsList = (ArrayList<ResolveInfo>)
				context.getPackageManager().queryIntentActivities( mainIntent, 0);

		// you can return 'pkgAppsList'
		// anyway, I need the following information,
		// so I just query what I need
		ArrayList<ApplicationInfo> listAppInfo = new ArrayList<ApplicationInfo>();
		for(ResolveInfo info: pkgAppsList) {
			listAppInfo.add(info.activityInfo.applicationInfo);
		}

		// return
		return listAppInfo;
	}

There you go, gotta do something with it.
Enjoy and have fun!

Cheers,
