Disable recent tasks button on Android 5.0

Question

I am working on an application that needs to suppress the recent apps button as it is done in the Toddler Lock application. What I want is user should not be able to exit my app

Answer 1

Finally I was able to achieve this by following:

@Override
protected void onPause() {
super.onPause();

ActivityManager activityManager = (ActivityManager) getApplicationContext()
        .getSystemService(Context.ACTIVITY_SERVICE);

activityManager.moveTaskToFront(getTaskId(), 0);

}

will need permission ...
