I believe I don't understand the question, I have tried final Button button1 = (Button) findViewById(R.i.button1)

I have tried Whatever I think Is on my repertoire, maybe I am missing some logic: I's tried final Button button1 = (Button) findViewById(R.id.button1); I also tried final Button mExterminateButton = (Button) findViewById(R.id.button1); Still not getting an proper answer! please help me understand. Thanks Ahead

First, where are you typing the code? Finding Views by id can't happen until you call setContentView() in onCreate() to attach the layout to the Activity. That means you have to be writing your code after that.

Second, the variable mExterminateButton is already declared as a member variable, so you don't need the type declaration again. The code you need to write should be mExterminateButton = (Button) findViewById(R.id.button1)

(Declaring the type again will create a separate local variable called mExterminateButton that will supersede the member variable, but will disappear after onCreate() is finished. The member variable will be left unset.)
