title: Android Overriding home key
body: <p>As the question suggests I know we can't override the Home key event but if you look into the emulator of <strong>android 2.2</strong> you will see an application <strong>Car Home</strong> it has overridden most of the keys like Home, end call.</p>
  
  <p>Now, the point is how have they done it? I tried to peep into the source code of the app but to my surprise its not available or I am unable to find it, but I don't think later is the case.</p>
