Professor, I have cleared my earlier problem and succeeded in installing Hello World App but at 11:31 minutes you told us to write some name in ID section of Attributes section but I am unable to find it at all. I am stuck in this problem from last two days and couldn't resolve it even with the internet solutions. Also I urge you to install Android Studio Chipmunk in Your Lab's Computer to help us to resolve the problems we are facing. Yes I know the lectures are made based on a one step earlier version of Android Studio. The solutions you will give will not much differ but with Installing Android Studio Chipmunk You will actually feel what the problems students are or may face(ing), it will not cost you more in Your labs to install that app from the same official website you have suggested in the tutorial.

Please help me out.
