Android SLF4J: NoClassDefFoundError android.util.Log

Question

Я портирую существующее приложение OSGi/Felix/iPOJO из окон на Android. Приложение использует SLF4J. У меня есть slf4j-android, развернутый как пакет. Однако я получаю сообщение java.lang.NoClassDefFoundError: android.util.Log в строке, где я пытаюсь создать экземпляр регистратора.

В документации SLF4J говорится, что мне нужен только бит slf4j-android в моем пути к классам, дальнейшая настройка не требуется. (http://www.slf4j.org/android/)

Мой регистратор объявлен как:

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

Строка трассировки стека жалуется на это:

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

Вот полный метод:

@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."); 
    } 
} 

Любые подсказки, почему я получаю NoClassDefFoundError на android.util.Log, когда я ссылаюсь на регистратор?

Answer 1

Проверьте, что база экспорта android.util пакет. Если нет, настройте Felix так, чтобы (добавив дополнительный пакет).

Также проверьте, что пакет android.til для Android slf4j импортирует пакет android.util.
