Actually my project was running file. Then i closed my project and try to create a new project and that time i was getting the above error and also in the old project. So now i have created one more project in another folder and the error gone. I think i found the reason, along with my project folder there is one more folder named appcompat_v7 so i was also closed that due to which i was getting error. Can u please explain what is the use of appcompat_v7.
