My app has three activities, A, B and C. I am moving from A to B through an OK button, and I want to move back from B to A by using the default back button of Android devices. W
When you are Ok button r u starting an intent...like
Intent int=new intent(context,B.class); startActivity(int);
then if you are not handling backbutton.
If use default back button...it will goes back to A.
Hope it helps...
