Answer 1

Here is the code you can use to keep the screen awake and never goes off while your application is running.

 getWindow(). addFlags (WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON)

This is one of the flag we can set to make the screen awake.

Put this inside your activity ex:- MainActivity inside onCreate().

Answer 2

If your app is running foreground, you can keep the screen on by add the following code into the each activity's OnCreate method of your project:

        protected override void OnCreate(Bundle savedInstanceState)
        {
             ....
          this.Window.AddFlags(Android.Views.WindowManagerFlags.KeepScreenOn);
        }

Or you can just add the android:keepScreenOn="true" in the every layout.xml file, such as:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:keepScreenOn="true"
    android:layout_width="match_parent"
    android:layout_height="match_parent">
</RelativeLayout>
