LibVLC vlcjni library

I want to make a media player using libVLC on Android. When I launch my application, it makes me Can't load vlcjni library: java.lang.UnsatisfiedError:Couldn't load vlcjnilibrary... findlibrary returned null

I am using eclipse and android ndk path is already set.

I have all the .so files in jni/libs/armeabi-v7a.

I still didn't find the solution on the net... Did I miss something on project configuration ? Help me please ! Thanks !
