RC 2019-07-22: 64-bit Android and Google Play Fixes.
A new RC has been released.
It fixes a problem with Google Play Game Service, but most importantly it includes 64-bit engine binaries, which is a requirement of the Google Play Store in August.
Many of you have asked about this issue as a warning has popped up as you submitted you apps. This is Google's official post about the issue: https://android-developers.googleblog.com/2019/01/get-your-apps-ready-for-64-bit.html
In order to support a 64-bit build you will need to set the minimum SDK version to 21 (the first SDK to support 64-bit).
Thank you for your patience as we worked on this issue. We have not submitted an app to the store yet, so we aren't 100% certain that this APK will meet their requirements, but we have tested the app on both 64-bit and 32-bit devices and games are running smoothly.
Please report problems to this thread and we'll keep an eye here. When reporting issues, please remember to include your device type, OS version, and if you know, whether the devices is running 64 or 32 bit Android. (You can use an app like AnTuTu benchmark to find details about your device).
The goal is to promote the RC to mainline by the end of the week.
