Firebase身份验证无法在已签名的APK中运行 [英] Firebase Authentication Not working in signed APK

问题描述

我正在使用Firebase Google登录.它可以通过USB调试完美运行.但是，当我生成签名的APK时，它将停止工作.它无法登录.在Android 5.1及更高版本上使用它. Android 6.0.1.另外，如果未更新Google Play服务，则会提示用户更新该服务，因为该用户可能会离开该应用.如何关闭提示并解决错误?

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?

我遇到了同样的问题，并使用这些方法解决了该问题.

I had the same problem and I fixed the problem using these methods.

1. 按照以下说明在Play商店控制台上完成应用程序签名:如何启用Google Play应用签名

转到Firebase控制台的设置">常规">您的应用">(选择您的项目)，然后从您的Play商店的应用签名证书中添加SHA-1.您可以通过如下图所示的发布管理"->应用签名"来获得SHA-1.

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.
