私はアンドロイドプログラミングに非常に慣れていません。壁紙の背景を設定する簡単なアプリを作成して、アンドロイドを学ぼうとしています。Android 開発には、まだ知らない、理解していない基本的な概念がたくさんあることを認めます。よろしくお願いします。
Android SDK 4.1、Eclipse Indigo を使用しています。
AVD仕様を設定しました:
CPU/ABI: ARM (armeabi-v7a)
Target: Android 4.1 (API level 16)
Skin: WVGA800
SD Card: 512
アプリケーションを実行するたびにエラーが発生します。
エラー:
