Hi, let's see if I can help you out :-)
- EditText gameObjective = (EditText) findViewById(R.string.gameObjective); Button button = (Button) findViewById(R.string.submitButton);
findViewById is looking for views (ui elements defined in your layout XML files) and should have a reference to R.id, not R.string.
I think you might have gotten confused by the fact that you have named your string and id elements the same (gameObjective).
TextView textField = (TextView) findViewById(R.id.textField);
EditText textField = (EditText) findViewById(R.id.textField);
3). Then in onClick, to get number do:
String yourNumber = textField.getText().toString();
I would change it to new OnClickListener().
Check the console in Eclipse when launching the app. If it doesn't install for some reason you will see why here.
If it fires up like it's supposed to, check DDMS/Logcat for Exceptions. If you still have problems you can post it back to me here or export the entire app from Eclipse to a zipped file and I can tell you what the problem is :-)
Thanks a lot!
