Integrate Google Play Services with Blueprint

[OmniOwl]

Vipar has been helping me troubleshoot my problem and we have found that an initial APK file should be uploaded as a shipment build so that it becomes signed with your keystore file. After which you can test locally by compiling shipping builds and pushing them to your phone.

You’ll need to make your own keystore file to do this. See Sign your app  |  Android Studio  |  Android Developers for information on how to do this. Keytool can be found in your JDK\Bin folder. (default: C:\NVPACK\jdk1.7.0_71\bin)

Google Play Services will NOT work on development builds.

I already did mention this part somewhat:

• Unreal Engine 4.9.2 or Newer
• Got a Google Developer Account (One time payment of 25 dollars)
• Got an APK ready to upload or already uploaded to the Google Developer Console
• Got a working Alpha/Beta/Production build on the Google App Store. (In this case mine is in Closed Alpha)
