I have an Android app where application module depends on a few library modules. Each of the library modules have: -

1. Different package names defined in their AndroidManifest.xml
2. strings defined in their res/values/strings.xml

Application module has a different package name defined in its AndroidManifest.xml

I am trying to access the strings from the library modules in my application module via

textView.setText(R.string.stringLibA);
textView1.setText(R.string.stringLibB);

However, I am getting compilation error when accessing R.string.stringLibB saying

cannot find symbol R.string.stringLibB

But it works fine if I access stringLibB using library's package name

textView.setText(R.string.stringLibA);
textView1.setText(com.package.libraryB.R.string.stringLibB);

Can someone please guide me what am I doing here that I cannot access libraryB's strings from application module's R class directly?

I apologize I could not share actual code from the project because of privacy concerns.

EDIT My application module's build.gradle's dependency block

dependencies {
  implementation project('libraryA')
  implementation project('libraryB')
}

libraryA and libraryB are applying library plugin in their build.gradle

apply plugin: 'com.android.library'

I am trying to access strings declared in libraryA and libraryB inside of my application via application's R class

Please make sure your A module is a Library Module. Then all A module's resources will be built into its R class and merged to B module's R class. That means you can get R.string.stringLibB by both com.myproject.libraryA.R.string.stringLibA and com.myproject.libraryB.R.string.stringLibB.

I suggest you do "File->Invalidate Caches" or "Build->Rebuild Project", it should work.

You can also refer : https://developer.android.com/studio/projects to see more detail.

Check your dependency first, make sure all of your modules are declared properly. If you implement module properly then you should have access to the modules component including resources.

Sometimes, IDE errors happen. Simply, Invalidate & Restart will solve your problems.
