I can't figure out how to add Downloader Library and Licensing Library to Android Studio

Question

I\'m trying to use Google\'s Downloader Library and Application Licensing Service since my app is going to use APK Expansion. But the problem is I don\'t know how to add those 2

Answer 1

For anyone else coming along with similar problem.

I solved it by importing module (File->New->Import Module) and selecting the licensing and the downloader library folders each time.

Note however that the .project file for downloader has a line that throws Android off (correctly):

android.library.reference.1=../market_licensing

Remove this line and the module imports fine.

Thank you Google once again for your clear instructions and clean environment!!!

BTW: What the heck are they writing in their guide http://developer.android.com/google/play/expansion-files.html#AboutLibraries

"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)."

Does that even make any sense to anyone?!

Answer 2

I solved the problem in a very weird way.

I noticed that I can't import those 2 libraries directly to Android Studio because they are missing a lot of project files and therefore Android Studio doesn't recognize them as libraries.

I then imported both libraries to Eclipse so that everything neccessary was generated and then exported them directly to Android Studio.

That worked like a charm.

Maybe a weird way to import a library but at least it worked.

Answer 3

When I tried to import library, I met same issue, and I could resolve by adding 'include ':library-directory-name'

1. copy your library directory into your project
2. add "include ':library-directory-name'" in settings.gradle file same as include ':app'

Answer 4

I just wanted to add a comment that the .project file for downloader should point to correct dependency:

android.library.reference.1=../../market_licensing/library

Now importing downloader will also import licensing which depends and create the correct dependency.

EDIT: That libraries are rather old. I've found new versions here:
