There is compile error
public class MainActivity extends AppCompatActivity implements MainActivityView {
TextView counter;
Button button;
MainActivityPresenter presenter;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
presenter = new MainActivityPresenter(this);
counter = (TextView) findViewById(R.id.textView);
button = (Button) findViewById(R.id.button);
button.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
int count = Integer.parseInt(counter.getText().toString());
presenter.updateTextViewText(Integer.toString(count + 1));
}
});
}
@Override
public void changeTextViewText(String text) {
counter.setText(text);
}
}
public interface MainActivityView {
void changeTextViewText(String text);
}
public class MainActivityPresenter {
MainActivityView view;
public void MainActivityPresenter(MainActivityView view) {
this.view = view;
}
public void updateTextViewText(String text) {
view.changeTextViewText(text);
}
}

Treehouse TeacherIn MainActivityPresenter you've added a return type to the constructor. Take that out and you've got it:
public class MainActivityPresenter {
MainActivityView view;
public MainActivityPresenter(MainActivityView view) {
this.view = view;
}
public void updateTextViewText(String text) {
view.changeTextViewText(text);
}
}
Hope that helps!
