  • 明示的なアクティビティ クラス {com.myfirstapp/DisplayMessageActivity.java.DisplayMessageActivity} が見つかりません。AndroidManifest.xml でこのアクティビティを宣言しましたか?

DisplayMessageActivity のエントリをマニフェストに入れます.......

それ DisplayMessageActivity は最初のアクティビティです インテントフィルターを使用する その他 それを削除します。

<activity android:name=".DisplayMessageActivity" android:label="Demo App">
  <intent-filter>
    <action android:name="android.intent.action.MAIN" />
    <category android:name="android.intent.category.LAUNCHER" />
  </intent-filter>
</activity>

答えはlogcatにあります：

Caused by: android.content.ActivityNotFoundException: Unable to find explicit activity class {com.myfirstapp/DisplayMessageActivity.java.DisplayMessageActivity}; have you declared this activity in your AndroidManifest.xml?

次のようにマニフェストでアクティビティを宣言します<application>(つまり、と</application>タグの間のどこかに挿入します)。

<activity android:name=".DisplayMessageActivity" />

これはよくある初心者の間違いです...慣れる前に、このエラーを少なくともあと数回は予想してください。:)
