Huawei App Protected

[Cesarsk]

Huawei and other brands have a functionality called "App Protected".

By default, an app is not protected and it doesn't send notifications.

Adding a ifHuaweiAlert() method might be useful to check whether we're dealing with a Huawei smartphone and launch a dialog that warns the user to add this app as Protected App.

     final SharedPreferences settings = getSharedPreferences("ProtectedApps", MODE_PRIVATE);
      final String saveIfSkip = "skipProtectedAppsMessage";
      boolean skipMessage = settings.getBoolean(saveIfSkip, false);
