Before you get totally into this post, I would like to warn you regarding the use of these functionalities, because they aren't user-friendly and Android Play Store wouldn’t approve of these unless you have a very strong reason.

Add the following permission to AndroidManifest.xml

    ActivityManager activityManager = (ActivityManager) getApplicationContext()  
            .getSystemService(Context.ACTIVITY\_SERVICE);
