How To Ask Permission Or Automatically Set The Phone's Full Screen On Settings - Android Studio

I am trying to set my activity to full screen using this code below: private void hideSystemUI() { View decorView = getWindow().getDecorView(); decorView.setSystemUiVisibil

Solution 1:

this problem happen with me for 2 different devices and this because of the front camera notch or screen cutout.

I used this code in oncreate() :

hideSystemUI();
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.P) { 
getWindow().getAttributes().layoutInDisplayCutoutMode = 
WindowManager.LayoutParams.LAYOUT_IN_DISPLAY_CUTOUT_MODE_SHORT_EDGES; }

Or in the theme style xml file add this line :

<itemname="android:windowLayoutInDisplayCutoutMode">shortEdges</item>

Solution 2:

In your manifest file put

android:theme="@style/Theme.Design.NoActionBar" or

android:theme="@style/AppTheme"

and in your activity call hideSystemUI(); before setting the content view like this :

finalint flags = View.SYSTEM_UI_FLAG_LAYOUT_STABLE
            | View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
            | View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
            | View.SYSTEM_UI_FLAG_HIDE_NAVIGATION
            | View.SYSTEM_UI_FLAG_FULLSCREEN
            | View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY;

    getWindow().getDecorView().setSystemUiVisibility(flags);
    setContentView(R.layout.activity_main);
