Starting an Activity which extends SherlockMapActivity throws a NoClassDefFoundError exception

I'm trying to use the SherlockMapActivity to use the Sherlock action bar on a maps activity. But when the activity which extends from SherlockMapActivity is started a NoClassDefFoundError exception is thrown telling me the class cannot be found.

When I change the implementation and use the normal MapActivity as a base class then the activity starts without any problems.

I included the actionbarsherlock-plugin-maps-4.0.0.jar int the lib folder and included it in the class path. Support library 4 is also included. The Sherlock action bar works an all other activities which don't extend from SherlockMapActivity.

I don't now whether this might be important,the map activity using the Sherlock action bar is part of a library project.

Any ideas on that?

UPDATE 2

I've temporarily replaced the map activity with a plain one, containing no custom code, just extending SherlockMapActivty. It crashed to the same reason.

Solution

  • You have to keep your .jar file inside libs not lib folder after ADT-17. Also, its not mandatory to Build Path it will be managed on its own.
