Fat aar does not include modules resources in Android

Question

I want to generate a fat-aar of an app module and use it as a dependency in another app.

I have used this library to generate the fat-aar.

I have an app module which is converted as a library module and a feature module called splash and Splash module is included in the app module.

With the help of above library I have successfully generated the fat-aar, but this fat-aar doesnot include the drawable resources of Splash module which crashes the app at run time with below exception.

java.lang.NoSuchFieldError: No static field ic_app_splash of type I in class 
Lcom/app/passenger/R$drawable; or its superclasses

This ic_app_splash is present inside the splash module.

Please provide the solution as why the fat-aar is not including the resources of a module.

Answer 1

I suppose that is Issue 406. Reading the associated issues your problem might be solved with the answer to Issue 19 and the corresponding explanation by the lib's dev which, in short, is:

The support lib version that your application uses is best to be the same as the library uses.

Note, that the developer also states:

I am no longer engaged in research and development, so the project will not be updated and maintained.

However you can also use the probably more common way, and either create AARs with Android Studio or via CLI with AAPT.
