Question

I created a android app which is linked to Firebase . But i forgot to give package name so by default it took "com.example.abc.appname" . Here the problem is when i am uploading app in google playstore its not accepting release apk with generated with that file name.

1. So how to change package name without getting any conflicts as it is linked to firebase.
2. google plus 登录也存在问题，它在调试模式下工作正常，但无法通过发布模式进行身份验证。我没有找到任何解决方案。应用程序处于发布阶段，我正面临这些问题。

Answer 1

您无法在控制台中更改应用数据。您必须删除该应用程序，并根据需要添加一个具有正确包名称和 SHA-1 的新应用程序。您必须重新创建针对应用程序的任何信息，例如远程配置参数。这不会删除与项目关联的任何数据，例如数据库值或 Cloud Storage。
