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!

LocationManager alm = (LocationManager) context.getSystemService(Context.LOCATION_SERVICE);
if (alm.isProviderEnabled(android.location.LocationManager.GPS_PROVIDER)) {
    Stuffs&Actions;
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;
                Works fine. I used the package name as third parameter and then checked the length of the activities list. If it is 0, means not launcher.

                The documentation for getPreferredActivities suggests that the first argument should be an empty list that is populated by the method. What exactly is the behavior when you are giving a list that is already populated as in your example?

                I checked the android source code. There is no effect from adding a filter as you do in your example. I believe a better way to check for a default activity is to use resolveActivity as in this answer to a similar question.

                How would you find all of the preferred activities for all of the intents that have them? You would need to go over all of the apps, prepare a filter for each intent on the app's manifest, and then use this method?

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;
val Context.isMyLauncherDefault: Boolean
  get() = ArrayList<ComponentName>().apply {
    packageManager.getPreferredActivities(
      arrayListOf(IntentFilter(ACTION_MAIN).apply { addCategory(CATEGORY_HOME) }),
      this,
      packageName
  }.isNotEmpty()
