I have tried to resolve that by checking redundancy in project classes/packages with any chance ..

Can someone help me .. ?

Answer 1

Problem solved !

I have included two definitions of GestureUtils.class because I have used the hidden pack framework.jar which has this conflict with android sdk ..
