APK Expansion Files: Specifying library path in Android Studio (Windows)

Question

I am on Android Studio (Windows 10). I have been trying to follow the steps in https://developer.android.com/google/play/expansion-files.html but am stuck at the section "Preparing to use the Downloader Library". I have downloaded and installed Google Play License Library and Google Play Downloader Library. I have created the corresponding modules. But when I go to Module Settings and specify the path to the Library Repository, I get errors and when I open up Module Settings again, the Library Repository field remains blank. The error I get are :

10:23:57 PM IncorrectOperationException: Error while applying changes: cannot create file from text: C:\Users\n56\AppData\Local\Android\sdk\extras\google\market_apk_expansion\downloader_library\
10:36:23 PM IncorrectOperationException: Error while applying changes: cannot create file from text: C:\Users\n56\AppData\Local\Android\sdk\extras\google\market_licensing\library\

And the library repository paths I specified are :

C:\Users\n56\AppData\Local\Android\sdk\extras\google\market_apk_expansion\downloader_library
C:\Users\n56\AppData\Local\Android\sdk\extras\google\market_licensing\library\

I have tried various things like escaping the backslashes, importing the modules instead of clicking New Modules but to no available.

Would be grateful for any help. TIA.

The documentation of this tutorial miss the reference of the Android Manifes.xml file on the path for each android-library.

The correct path for each library are:

Google Play License Library <sdk>/extras/google/play_licensing/library/AndroidManifest.xml

Google Play Downloader Library <sdk>/extras/google/play_apk_expansion/downloader_library/AndroidManifest.xml

I noticed that on other tutorial from Google where use the same library for setting up the Licensing Verification Library

ANSWER UPDATED: These previous method only reference one file of the whole library. Actually I revert all this steps to use a library from gradle whit all we need to use Google Play License Library and Google Play Downloader Library there is the link for the repository

I tried and made it work with below Tags in individual Module's build.gradle . flatDir is the key to solution. and for Windows based Android Studio, the '\' needs to be escaped using double '\' backslashes.

repositories {

     flatDir {
          dirs "C:\\Users\\<username>\\AppData\\Local\\Android\\sdk\\extras\\google\\market_licensing"
     }
}

I am still learning, but I think it has something to do with flatDirs container which should be child of repositories container.

it is now showing up a bit different but the Gradle Sync just works.
