Native Extension ClassNotFound

Hi,

I created a clean air native extension with a simple function that starts an activity from within the ANE, 'DumbActivity'. It worked.

However, after having DumbActivity extend YouTubeFailureRecoveryActivity in order to start using the YouTube API 3.0, I got a ClassNotFoundException on DumbActivity when I run the ANE.

Worth mentioning that when I run the code as a native android app, it runs properly, and I can use YouTube abilities. Also checked, the DumbActivity class is included in the Jar.

Is that some sort of library conflict or something?
