Courses Plus Student 385 Pointserror: cannot find symbol class Button
Here is my code from MainActivity.java.
public class MainActivity extends ActionBarActivity {
private EditText mNameField;
private Button mStartButton; // the error with 'Button'
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mNameField = (EditText)findViewById(R.id.nameEditText);
mStartButton.setOnClickListener();
}
}

I think the problem with your code is that you forgot to initialize the Button, try adding the following code before your setOnClickListenter();
mStartButton = (Button) findViewById(R.id.insertYourButtonIdHere):

11,161 PointsI had the same problem as you and I figured it out! instead of actually typing out the word Button and EditText just start typing them and then click on Button for autocompletion. Next to that option it'll say android widget. Weird that it makes a difference but that'll solve your problem.
