EditText parse to int HELP

First, hi to all of you. :)

I am learning Android and I am making some basic math program(game). It gets two random numbers, random operator, and 30 secs to solve math problems as much as you can.

I get error when I try to get text from EditText(Numbers only) and parse it to int. I need it because I need to compare real result to user input result.

I compile it, but when i run it on emulator, i got this error on ddms.

You've declared your EditText but you never set it to anything, thus it is null.

EditText et1;

You need to add a findViewById() call for your EditText inside your onCreate, like you've done for your TextViews. Something like this is what you need I think.

et1 = (EditText) findViewById(R.id.editText1);

You should also really really use descriptive names for your variables. Using names like textView1, textView2, editText1 etc... is going to make your code A LOT harder to debug. Consider naming them something to do with what they are used for

firstOperandTxt, secondOperandTxt, answerEdt etc..

You have not initialized your EditText et1, hence you see NullPointer Exception. You should have something like
et1 = (EditText)findViewbyId(R.id.youtextid);
