I need to do a program initialization, how to control the interface?

            
Sometimes the procedure done once initialized, this time do not want the interface to be operated, how it should be handled?

I would like to handle it, covering a AlertDialog.Builder bd = new AlertDialog.Builder (this);

The question is: After the initialization process, how to destroy this bd
?
Reply:
Set bd = null;
GC was given then automatically recovered.
