Android Google 日历 API 推送到 Google 播放时无法正常工作
Android Google Calendar API not working when pushed to Google Play
我在使用 google 日历 api 和 android 时遇到问题。一切正常（调试 + 发布）但是当将发布 apk 推送到 Play 商店时，下载的版本在尝试使用 api 时抛出异常。我正在记录产生的错误：println("couldn't insert into Google Calendar! " + e.message)
这是 I/System.out: couldn't insert into Google Calendar! null
这是 kotlin 的东西还是我遗漏了什么？
