"have Activity 1 use
startActivityForResult() to start up Activity 2, with Activity 2
sending the result back via setResult(), followed by finish(). "
ok, thats exactly what the activities do; but the result back doesnt
work when the hardware keyboarb (back) is used.
What actvity 2 does is:
public void goBack(){
rit = new Intent();
rit.putExtra("updatedYellowR", yellowR);
rit.putExtra("updatedBlueR", blueR);
rit.putExtra("updatedRedR", redR);
setResult(RESULT_OK, rit);
finish();
}//goBack
yelllowR, blueR and redR are instances of the same class ...
objects....
