Question:
The application should be shown in full screen without panels. To do this, I write android:theme=" @android :style/Theme.NoTitleBar.Fullscreen" in the manifest for the entire application. In android 4.1.2 all panels are removed. When I put the same application on 4.0.4. The top panel (as I understand it, it belongs to the activity) is removed, while the bottom (system) panel remains.
Is it possible to hide the system bar in this version of android? Can this be done without root?
Update: found the following options:
//Скрывает значки на панели, вернее превращает их в маленькие точки, панель не скрывает
View.setSystemUiVisibility(View.SYSTEM_UI_FLAG_LOW_PROFILE );
//Судя по описанию должна скрывать панель, но у меня, опять-таки не работает
View.setSystemUiVisibility(View.SYSTEM_UI_FLAG_HIDE_NAVIGATION);
//То же самое, тоже не работает
View.setSystemUiVisibility(View.SYSTEM_UI_FLAG_FULLSCREEN);
There are no solutions yet.
Answer:
In my opinion it is impossible. There was even an article on this topic on Habré: Kiosk Mode apps on Android .
