Importing from eclipse to android studio?

Question

I wanted to import some projects from Eclipse to Android Studio, I've already used the option where you export it as a .gradle file and open it in the Studio. But I also tried a method where I create a new project in Studio and the copy the main_activity.java and the important files in the res folder. But then when I open the main_activity.java, it immediatly gives me an error. Could not resolve R I've already searched for an answer and somebody came up with adding import android.R; or import com.example.package; the first one works for the 'R' issue but then Gives me an error in which it says that setContentView cannot be resolved. And the second line doesn't do anything.

I faced that problem too, Do the following things,

1. do update your ADT to r22,
2. get update of r22 in ADT,
3. Close your project from File-Close Project
4. Exit from Studio,
5. Launch Studio again,
6. Select your project from recent projects which are displayed in left panel of Home
