Android Unable to instantiate activity: Didn't find class on path

Question

I\'ve imported project into eclipse and when I try to run it, then this exception is thrown:

java.lang.RuntimeException: Unable to instantiate activity Compone

Answer 1

After i spend a while on this problem, the solution that i found is a conflict between importing Properties > Android - appcompat_v7 and appcompat_v4 that was added in the libs folder. After i remove the appcompat_v4 the error no longer appear. I hope that answer can help in the future someone.
