I want to make Option Menu for Android, I have visit this site. In their script, I found onPrepareOptionsMenu, I try to compile and run using Android 2.3.3 compiler with and without onPrepareOptionsMenu, both works, but I didn't see any difference.
public boolean onCreateOptionsMenu(Menu menu){
//code here
}
public boolean onOptionsItemSelected(MenuItem item){
//code here
}
public boolean onPrepareOptionsMenu(Menu menu){
//code here
}
What is actually onPrepareOptionsMenu method do? Is that method important? Could I just delete the method?
Addition
Oh, I also hear about Action Bar in Android 3.0, it says that Action Bar is the alternative way for make Option Menu, and it using onPrepareOptionsMenu. Is that right?
Thank you...
