Блог

Я создаю бизнес-приложение и должен блокировать любое другое приложение, которое пытается открыть пользователь. Я создаю для него сервис, но он не работает.

При запуске он не видит другие приложения при открытии пользователем.

Я прочитал некоторые другие сообщения здесь, но я не мог решить.

Ниже приведен мой сервис.

 protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main_activity);

        startService(new Intent(this, clsServico.class));
    }
