App Gradle 配置如下：
- 编译SdkVersion 27,
- buildTools版本“25.0.3”
- minSdkVersion 16,
- 目标SDK版本24
- support_library_version = '27.1.0',
- google_play_services_version = '12.0.1'**
注意：仅在发布版本中出现此错误，而在调试版本中则没有。
谢谢。
看起来这是一个错误appcompat-v7 27.1.0: https://issuetracker.google.com/issues/74289571 https://issuetracker.google.com/issues/74289571
