I am porting an existing OSGi/Felix/iPOJO app from a windows over to Android. The app is using SLF4J. I have slf4j-android deployed as a bundle. However I am getting a java.lang.NoClassDefFoundError: android.util.Log on the line where I am trying to instantiate the logger.
The SLF4J documentation says that I only need to have the slf4j-android jar on my classpath, no further configuration is necessary. (http://www.slf4j.org/android/)
My logger is declared as:
private static final Logger logger = LoggerFactory.getLogger("DefaultActionManager");
The line the stack trace is complaining about is:
logger.info("Bound new action list for state " + state);
Here is the full method:
@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.");
}
}
Any clues why I am getting a NoClassDefFoundError on android.util.Log when I reference the logger?
Full stack trace:
