既存の OSGi/Felix/iPOJO アプリを Windows から Android に移植しています。アプリは SLF4J を使用しています。slf4j-android をバンドルとしてデプロイしました。ただし、ロガーをインスタンス化しようとしている行でjava.lang.NoClassDefFoundError: android.util.Logを取得しています。

SLF4J のドキュメントによると、クラスパスに slf4j-android jar を配置するだけでよく、それ以上の構成は必要ありません。( http://www.slf4j.org/android/ )

私のロガーは次のように宣言されています：

private static final Logger logger = LoggerFactory.getLogger("DefaultActionManager");

スタック トレースが不平を言っている行は次のとおりです。

logger.info("Bound new action list for state " + state);

完全な方法は次のとおりです。

@Override
@Bind(aggregate = true)
public void bindActionList(final ActionList actionList) {
    final State state = actionList.getState();

    final ActionList replacedActionList = actionLists.put(state, actionList);
    logger.info("Bound new action list for state " + state);

    if (replacedActionList != null) {
        logger.warn(state + " previously had an action list associated with it. This new action list replaced it.");
    }
}

ロガーを参照すると、android.util.Log で NoClassDefFoundError が発生する理由はありますか?

フレームワークが android.util パッケージをエクスポートしていることを確認します。そうでない場合は、Felix がそうするように構成します (追加のパッケージを追加して)。

また、android slf4j バンドルが android.util パッケージをインポートしていることも確認してください。
