[code]package com.bignerdranch.android.geoquiz;

import android.app.Activity;
import android.os.Bundle;
import android.view.Menu;
import android.view.View;
import android.widget.Button;
import android.widget.TextView;

public class QuizActivity extends Activity {

private Button mTrueButton;
private Button mFalseButton;
private Button mNextButton;
private TextView mQuestionTextView;

private TrueFalse[] mQuestionBank = new TrueFalse[] {
		new TrueFalse(R.string.question_oceans, true),
		new TrueFalse(R.string.question_mideast, false),
		new TrueFalse(R.string.question_africa, false),
		new TrueFalse(R.string.question_americas, false),
		new TrueFalse(R.string.question_asia, true),

private int mCurrentIndex = 0;

protected void onCreate(Bundle savedInstanceState) {
    mQuestionTextView = (TextView)findViewById(R.id.question_text_view);
    int question = mQuestionBank[mCurrentIndex].getQuestion();
    mTrueButton = (Button)findViewById(R.id.true_button);
    mTrueButton.setOnClickListener(new View.OnClickListener() {
    	public void onClick(View v) {
    		Toast.makeText(QuizActivity.this, R.string.correct_toast, Toast.LENGTH_SHORT).show();
    mFalseButton = (Button)findViewById(R.id.false_button);
    mFalseButton.setOnClickListener(new View.OnClickListener() {
    	public void onClick(View v) {
    		Toast.makeText(QuizActivity.this, R.string.incorrect_toast, Toast.LENGTH_SHORT).show();

public boolean onCreateOptionsMenu(Menu menu) {
    getMenuInflater().inflate(R.menu.quiz, menu);
    return true;



I found the problem.
I deleted or forgot to create the TrueFalse.java class.
Now that i created it it should work.
