hi Mark , Thanks for your reply , but still I'm not aware why, only when the "press()" is commented out from "onKeyDown()" method (i can say from logcat) ,the onKeyDown is invoked for every hit of the appropriate key .When I run the program without commenting press() from onKeyDown ,the call back method onKeyDown is called only once for the very first-time hit on the key.why is this varied behavior.
