i have Solved this issue and i thought of sharing it with everyone.
I have noticed that there is a new Android Package named as Android Private Libraries and after hours of trying i found a way to fix this.
Right Click on your Project then
Goto Build Path-> Configure Build Path -> Order and Export
when you are there you should check the Android Private Libraries and then click OK button.
if you still face the problem delete all the files inside your bin folder and rebuilt you project.
Hope this helps others who are facing the same problem as me
