Can't find lib via transitive use of sub module

Question

Android Studio 3.4.2

I has main project (app) that use module mytransport like this:

app/build.gradle

dependencies {
    annotation         


        

Answer 1

Use api instead of implementation.

In mytransport/build.gradle:

dependencies {
   //...
   api 'com.google.code.gson:gson:2.8.5'
}

Just an example.

In library/build.gradle:

dependencies {
    api project(':libraryA')
}

In app/build.gradle:

dependencies {
    api project(':library')
}

In your app you will be able to access both library and libraryA.

Using the implementation configuration:

In library/build.gradle:

dependencies {
    implementation project(':libraryA')
}

In app/build.gradle:

dependencies {
    implementation project(':library')
}

In this case in your app you can't access the libraryA methods.
