Accessing application resources from the library project

Question

My application depends on a library project.

The menu.xml file is within the application project.
All the java code is within the library projec

Answer 1

I found @triad's solution with Resources.getIdentifier(String, String, String) to be somewhat error-prone:

• the String-literal resource identifiers aren't checked by the IDE
• multiple sequential String arguments to a single method are easy to use incorrectly.

I found this approach to work better for me:

String libString = context.getString(example.library.pkg.R.string.library_string)

Where the library's package is example.library.pkg.

• The library's R class is resolved at compile-time, so your IDE will tell you if you referenced it correctly
• Not importing the library's R class allows you to still use your own local R later, and explicitly marking the external resource usages makes them easier to spot.
