Answer 1

Try to remove the android-support-v4.jar file from the libs folder of your project.

Good Luck.

Answer 2

If there is any JAR file with same name in the libs folder of the Library and your Project , they must have the same size(same jar files).

If now just replace one of them with the other

Answer 3

The Android FacebookSDK includes its own version of android-support-v4.jar , and it's most likely the conflicting jar .

Open project preferences, select Java Build Path and remove android-support-v4.jar from the root, and things should compile well again.

Answer 4

I think there exist a better solution for solving this problem than removing the android-support jar being used. It might cause some other errors to your project. I solved this problem by removing the support jar of fb sdk and then updating its support library to the version we have in our project and then add the library project to your project and it will compile with out any errors

Answer 5

This is happening because the FacebookSDK brings with it its own version of android-support-v4.jar. You may remedy this by following these steps:

1. Delete android-support-v4.jar from your own android project
2. Delete android-support-v4.jar from appcompat_v7
3. Copy android-support-v4.jar from your FacebookSDK project
4. Paste this copied jar in the places where you deleted the others

This is less risky then outright deleting the jars from the two projects. This not only remedies SHA-1 hash issues. It will also help with res errors that may popup in your appcompat_v7 project post addition of the FacebookSDK into your project.
