How to disable the Recent Tasks/Apps button in Android

view story

http://stackoverflow.com – I'm building a child play application for Android. I need to disable all keys when it is in use. I have set the Application as the Home App and disabled the back key (that takes care of the Home and Back button). In order to clear the recent tasks list I've created a list of Dummy Activites which start and then finish when the application starts. The Dummy Activites look like: public class Dummy1 extends Activity { public void onCreate(Bundle paramBundle) { super.onCreate(paramBundle); finish(); } } And then in my onCreate of the application I perform: this.pm.setComponentEnable (HowTos)
