Step 1

Add this permission to the manifest.xml file

Step 2

Put this code in any Activity on which you want to block/disable the recent apps button

@Override protected void onPause() { super.onPause(); ActivityManager activityManager = (ActivityManager) getApplicationContext() .getSystemService(Context.ACTIVITY_SERVICE); activityManager.moveTaskToFront(getTaskId(), 0); }

I have tried in several devices and it is working perfectly. Pressing the recent apps button may turn the screen black for less than a second but will bring your activity back again.
