Where is the R.java file in Android Studio?

Question

Where is the R.java file in Android Studio? Can someone please help with this? I already tried google for the answer but can\'t find any solution.

Answer 1

I use Android Studio 2.3.3. The R.java file is shown in the picture above.

In the left upper side, there is a select list. Select the [project] option so that you can see all the folders and files.
