用google-play-services.jar替换com.google.android.gms：play-services

I am building a google maps app on android using android studio When I released the first version of my app, no one was able to view the google maps as google play services must be installed on the devices by users ( I cant ask people to download that in each device) so I want to embed it into my app.I am building a google maps app on android usin
