Emulator 28.0.19 在 Canary 和 Dev channel 都可用了，Emulator 是 Android Studio 中的模拟器。
主要更新如下：
Fixed an issue in macOS 10.14+ where the virtual scene camera mouselook control could become too sensitive due to an interaction with new accessibility security settings.
Fixed an error in timezone calculation that could result sporadically incorrect setting of the emulator clock.
Fixed rendering errors in various cocos2d and Unreal engine apps. If you are interested in or are currently using the emulator for game development, we are interested in making that experience as high fidelity as possible and would appreciate feedback in Issuetracker.
