android Facebook SDK崩溃的应用程序？

Question

I am trying to add facebook login in my application , i followed every thing at this example

https://developers.facebook.com/docs/android/login-with-facebook/

also I've Downloaded the sdk and all examples are working fine ,

But my problem is when i attempt to copy every thing from the example project to my project , my application crashed if i added FaceBook session

 Session session = Session.getActiveSession();

 if (session == null) {
     if (savedInstanceState != null) {
         session = Session.restoreSession(this, null, statusCallback, savedInstanceState);
     }
     if (session == null) {
         session = new Session(this);
     }
     Session.setActiveSession(session);
     if (session.getState().equals(SessionState.CREATED_TOKEN_LOADED)) {
         session.openForRead(new Session.OpenRequest(this).setCallback(statusCallback));
     }
 }

this is the log :

Answer 1

The library 'android-support-v4.jar' should be same in both Facebook lib project and your project. because it seems like the different projects are using 2 separate support libraries and there checksum is different.

For more details check Facebook SDK for Android duplicate support library on dependencies

Hope this helps..

Answer 2

经过数小时的搜索此问题后，问题是我不得不从Facebook库中复制android-support-v4.jar并在我的项目android-support-v4.jar其替换为android-support-v4.jar ，这对我android-support-v4.jar ，但我不知道为什么
