Cannot resolve symbol R when move class out of default package

When my "ExampleAdapter" class is in the sample package as my MainActivity, I don't get an error. Let's say my MainActivity is in "com.example". When I create a new package inside of the "com.example" package (let's say "com.example.adapters"), and move my "ExampleAdapter" to the new package, I get the dreaded error, "Cannot resolve symbol 'R'". Why does it matter which package my adapter is in?

The R and BuildConfig classes are always code-generated into the Java package that you name in the package attribute of your <manifest> element in your AndroidManifest.xml file. Any Java classes outside of that package that need to refer to R or BuildConfig need to add the corresponding import statement, as with any other Java class from a foreign package.
