Is it possible to adjust the screen dimmer and the lock screen on Android?

Hello,

Is it possible to adjust the screen dimmer and the lock screen on Android?

Yes, you can open your Activity1.cs, then override the OnAttachedToWindow method. Then create a method, set the KEEP_SCREEN_ON flag and DismissKeyguard flag in WIndow. And set TurnScreenOn and ShowWhenLocked to true. I test it in my devices, it will not lock the screen when application running.

You can refer to the following code.

public override void OnAttachedToWindow()
{
     base.OnAttachedToWindow();
     DisabletheLockScreen();
}
 
private void DisabletheLockScreen()
{

 
     Window.AddFlags(WindowManagerFlags.DismissKeyguard |WindowManagerFlags.KeepScreenOn);
   if (Build.VERSION.SdkInt >= BuildVersionCodes.O)
     {
         SetTurnScreenOn(true);
 
         SetShowWhenLocked(true);
    }
     else
     {
         Window.AddFlags(WindowManagerFlags.ShowWhenLocked | WindowManagerFlags.KeepScreenOn);
     }
}
