Step 1

Add this permission to the manifest.xml file

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

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.
