问题
Im trying to deal with a facebook integration login for my simple android application. Im following this guide https://developers.facebook.com/docs/getting-started/facebook-sdk-for-android/3.0/ and everthing seems to go fine, but am still gettin exception: java.lang.NoClassDefFoundError: android.support.v4.content.LocalBroadcastManager
I know there are alot similar questions about this problem like this java.lang.ClassNotFoundException after changing nothing in the project but upgrading eclipse android sdk that says that I must check all the checkboxes in java build path in Other and export tab but Ive done it already and am still getting the error.

I had the same issue and scoured the internet for solutions. I read many of the suggestions posted in answers like the one you linked and none of them seemed to work. I ended up getting it to work. My issue was that I had misunderstood several of the other posts. I thought that when they said "make sure android-support-v4.jar was in your libs folder" they were referring to the android-support-v4.jar in the FacebookSDK project.
Once I added android-support-v4.jar to my project and followed the other suggestions related to Order and Export. After cleaning and rebuilding the project it no longer crashed. Hope this helps! Good Luck!

I also faced the same problem and solved it. I copied and pasted myproject's android-support-v4.jar into Facebook SDK's lib folder. That makes it work.
