TabActivity back key Event [Android]

It turns out to be pretty easy. Add the following code to your child tab activity :

 @Override
  public void onBackPressed() {
    this.getParent().onBackPressed();   
  }

Then in the TabActivity do the real logic:

 @Override
  public void onBackPressed() {
    // Called by children
  }

Otherwise, the children will intercept and consume the event without notifying the tab host.
