NewBostonチュートリアルを使用してAndroidアプリケーション開発を学んでいます。レッスン21を完了しましたが、コードを実行すると、スプラッシュ画面(つまりロゴ)の後にアプリケーションがクラッシュします。助けてください。このチュートリアルを終了したくありません。以下のデータ以外にEclipseから必要なものがあれば、私に知らせてください。前もって感謝します。

私のマニフェスト:

あなたはすべて大文字でマニフェストにあなたの活動を宣言しました。

 android:name=".MENU"

ただし、ActivityクラスはMenu.javaです。

これをに変更します

  android:name=".Menu"
