With "compatibility" files problems you can try to delete / or rename for security any appcompat "project" in eclipse and create a new project using a compatibility mode (different target and "required" SDK values, equals to your version needs), it will generate a new appcompat project, remember to link your existing project to this appcompat project and check your lib for no duplicate compat. jar.

Answer 5

Delete jar library from every directory you add. Then you need to add appcompat as a dependency. If you use Android Studio, you need to do as following:

add this

compile 'com.android.support:appcompat-v7:18.0.+'

into your gradle dependencies and after that, Build -> Rebuild Project.
