I am configuring the Apk Expansion Files follow this link https://developer.android.com/google/play/expansion-files
5. Select the Properties tab and in Library Repository, enter the library from the /extras/google/ directory (play_licensing/ for the License Verification Library or play_apk_expansion/downloader_library/ for the Downloader Library).
I am currently stuck on the step above. Could someone give me advice?. Thanks.
