I do not know what happened, but I could not find the libproject inside the Google Play services. I just updated it. My apk file became a jar file after cleaning the project, so I checked the Google Play services and I found that libproject is not added to the project. there are documents and samples, but on libproject.
I did not find any solution on the Internet, so I think that it is best to post here. Are there any issues with this update?
Someone please give me any idea to solve this problem.
