我遇到了同样的问题，我使用这些方法解决了这个问题.
使用这些说明在 Play 商店控制台上完成应用签名
I'm using Firebase Google Sign in. It works perfectly via USB debugging. But when I generate signed APK, it stops working. Its not able to sign in. Using it on Android 5.1 & Android 6.0.1. Also, if the Google play services is not updated, it gives user prompt to update it because of which user may leave the app. How can I turn off the prompt and solve the error?

Complete app signing on your Play store console using these instructions How to enable Google Play App Signing
Go to your Firebase console Settings > General > Your apps > (Select your project) then add the SHA-1 from App signing certificate from your Play store. You can get SHA-1 by going to Release management -> App signing as show in this image.
