You can import an Android Library plug-in created outside of Unity into your Unity project using the following steps:
  1. Copy the Android Library plug-in to the Assets folder of your Unity Project.
  2. If the Android Library plug-in root folder doesn't use the 
    .androidlib
    extension, add this extension to the folder. For example, 
    mylibrary.androidlib
    .
Unity now supports the Android Library plug-in and includes it in the final project that Gradle uses to build your application. For more information, refer to How Unity builds Android applications.

Configure an Android Library plug-in

Android Library plug-in is a dependency of a built-in module unityLibrary. You can change this default behavior. For example, you can configure an Android Library plug-in to depend on unityLibrary instead. To do this, use the following steps:
  1. In the Project window, select the 
    .androidlib
    plug-in to access the
    Inspector

    ?

    window.
  2. In the Select dependent module section, select None.

    Android Library plug-in Inspector with the Select dependent module setting selected.

  3. Add the following code in your plug-in's build gradle dependencies scope:
    dependencies {    ...    implementation project(':unityLibrary')    implementation fileTree(dir: project(':unityLibrary').getProjectDir().toString() + ('\\libs'), include: ['*.jar'])}
You also have the option to include Android Library plug-in as a dependency of the launcher or both unityLibrary and launcher built-in modules.
