Android Screen Sleep

Android Screen Sleep

Android Torch Application Code.

I was developing an application where user has to see the screen as long as he is interacting with my application. In this scenario user screen may go Off if user is inactive for some time. To avoid screen sleep while user is reading the screen you need to add below line of code when your application gets started.

@Override
    public void onCreate(Bundle savedInstanceState) {
        
        getWindow().addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);
        
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
}

onCreate method gets called when activity is created.

I have also modified application manifest file AndroidManifest.xml.

<uses-permission android:name="android.permission.WAKE_LOCK" />

This takes the permission from user to keep phone awake.

The code is very useful for those who would like to develop application like Torch. :)
