java.lang.ClassNotFoundException: com.facebook.unity.FB using Unity Facebook plugin v5.0.4 Beta

Question

I installed the v5.0.4 beta facebook unity plugin to resolve the orientation problem, since my game is in landscape mode. Everything works fine when publishing from Unity3d, but when I export into an eclipse project and run the game from it, I get the error:

AndroidJavaException: java.lang.ClassNotFoundException: com.facebook.unity.FB

I guess there is some file missing, any ideas how to resolve that?

Thanks!

Answer 1

The facebook sdk for unity has been changed to an additional library project from jar file. Since then, when building the project in unity, all facebook sdk files must be copied to the temporary project directory when building to build together. But it seems that all sdk files are not copied to the proper directory under the temporary android project for build. You can check it in the Temp/StaggingArea/android-libraries directory while building the project in unity. There must be Facebook directory in android-libraries while building your project. I'm not sure if it's unity problem or facebook problem. I think you should report it to the Unity.
