Building my first android game and am getting "cannot resolve symbol R" (lines 31-39) on several java files for instance my EnemyShip class. Using Android Studio ver 2.3.3. I have enemy ship png's in my resources folder so don't really know why I'm getting this error.
R is a generated class. You may need to manually import it in to your code.
The R class should be in the top-level package for application. For example, in my case the top-level package for the application is: com.mcleodnet.hflink, so my code imports: import com.mcleodnet.hflink.R
