The Android resource linking failed error can also appear if you have an error in any of your XML resources. In my case I was using the following line twice in one of my XML drawables in drawable folder:

<?xml version="1.0" encoding="UTF-8"?>
<?xml version="1.0" encoding="UTF-8"?>

I removed the duplicate line and the error disappeared. The error was a bit misleading:

Android resource linking failed Output: /Users/johndoe/Desktop/myapp/app/src/main/res/layout/activity_main.xml:2: error: resource drawable/bg_main (aka com.example.myproject:drawable/bg_main) not found.

According to the above error, the first thing you need to do is to proof read all the drawable resources that are accessed in the activity_main because the chances are higher that you will find the error. In the worst case scenario you might end up checking all your resource files.
