How to check if my application is the default launcher [duplicate]

Question

I am developing a buissness-application that is essentially a Home-screen, and is supposed to be used as a Default Homescreen (being a "kiosk"-application).

Is there any way of checking if my Launcher is the default Launcher? Thanks!

Ps. Similar example, but for checking GPS-settings

LocationManager alm = (LocationManager) context.getSystemService(Context.LOCATION_SERVICE); if (alm.isProviderEnabled(android.location.LocationManager.GPS_PROVIDER)) {     Stuffs&Actions; } 

Answer 1

You can get list of preferred activities from PackageManager. Use getPreferredActivities() method.

boolean isMyLauncherDefault() {     final IntentFilter filter = new IntentFilter(Intent.ACTION_MAIN);     filter.addCategory(Intent.CATEGORY_HOME);      List<IntentFilter> filters = new ArrayList<IntentFilter>();     filters.add(filter);      final String myPackageName = getPackageName();     List<ComponentName> activities = new ArrayList<ComponentName>();     final PackageManager packageManager = (PackageManager) getPackageManager();      // You can use name of your package here as third argument     packageManager.getPreferredActivities(filters, activities, null);      for (ComponentName activity : activities) {         if (myPackageName.equals(activity.getPackageName())) {             return true;         }     }     return false; }

boolean isHomeApp() {     final Intent intent = new Intent(Intent.ACTION_MAIN);     intent.addCategory(Intent.CATEGORY_HOME);     final ResolveInfo res = getPackageManager().resolveActivity(intent, 0);     if (res.activityInfo != null && getPackageName()             .equals(res.activityInfo.packageName)) {         return true;     }     return false; }
