Android ocultar / mostrar el icono de la aplicación mediante programación

Ocultar el icono de la aplicación utilizando el código siguiente:

 PackageManager p = getPackageManager(); ComponentName componentName = new ComponentName(this, com.apps.MainActivity.class); // activity which is first time open in manifiest file which is declare as <category android:name="android.intent.category.LAUNCHER" /> p.setComponentEnabledSetting(componentName,PackageManager.COMPONENT_ENABLED_STATE_DISABLED, PackageManager.DONT_KILL_APP); 

A continuación, se muestra cómo devolver el icono de la aplicación.

 PackageManager p = getPackageManager(); ComponentName componentName = new ComponentName(this, com.apps.MainActivity.class); p.setComponentEnabledSetting(componentName, PackageManager.COMPONENT_ENABLED_STATE_ENABLED, PackageManager.DONT_KILL_APP); 

Para ocultar el icono use esto:

 PackageManager p = getPackageManager(); ComponentName componentName = new ComponentName(this, com.apps.MainActivity.class); p.setComponentEnabledSetting(componentName,PackageManager.COMPONENT_ENABLED_STATE_DISABLED, PackageManager.DONT_KILL_APP); 

Y para mostrar el icono:

 PackageManager p = getPackageManager(); ComponentName componentName = new ComponentName(this, com.apps.MainActivity.class); p.setComponentEnabledSetting(componentName, PackageManager.COMPONENT_ENABLED_STATE_ENABLED, PackageManager.DONT_KILL_APP); 

IMPORTANTE: Es algo complicado si necesita hacer algo con la actividad principal en su aplicación cuando está oculta. Se enfrentará a una ActivityNotFoundException . Para que funcione, debe mostrar el icono antes de hacer cualquier cosa a su actividad principal y ocultarlo de nuevo después de que haya terminado.
Sencillos pasos: 1 llamada recibida aquí
2-unhide icono
Actividad principal de 3-launch
4-haz tus cosas en la actividad principal
5-ocultar icono de nuevo

Sólo use el siguiente código.

  PackageManager p = getPackageManager(); ComponentName componentName = new ComponentName("com.example.removeicon","com.example.removeicon.LauncherActivity"); p.setComponentEnabledSetting(componentName , PackageManager.COMPONENT_ENABLED_STATE_ENABLED, PackageManager.DONT_KILL_APP); 

Tenga en cuenta que el icono puede no desaparecer hasta el siguiente reinicio.
