Android 谷歌登录可以在模拟器中工作，但不能在手机中工作

我在使用Firebase实现Google登录时遇到了一个非常严重的问题。 我可以使用仿真器Android 7.0（为x86_64构建的SDK）登录， 但是如果我把我的项目上传到我的手机上（安卓6.0），我就不能用谷歌登录。 我唯一看到的是，应用程序关闭了。在极少数情况下，如果我快速双击“登录”按钮，它将登录，但不会获得进一步使用的凭据。 可能是什么问题

LoginActivity中的代码

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    if(requestCode == FirebaseConstants.LOG_IN_REQUEST){

        GoogleSignInResult result = Auth.GoogleSignInApi.getSignInResultFromIntent(data);
        Intent i = new Intent(LoginActivity.this, MainActivity.class);
        startActivity(i);

    }
    if(requestCode == FirebaseConstants.LOG_OUT_REQUEST){
        TastyToast.makeText(this, "Logged out successfully", TastyToast.LENGTH_LONG, TastyToast.SUCCESS);
    }
}

以下是onCreate方法中的代码（单击按钮）：

如果您的调试版本在使用Google登录登录Firebase时未引发任何错误，则可能是证书签名问题

步骤1（可选）

在所有catch块中创建Toast消息，以便查看错误代码。正常构建并签署应用程序；然后将其作为闭合或开放轨道释放以进行测试。联机搜索错误代码。（不要只依赖描述，搜索其他资源）

步骤2

检查您的发布apk/捆绑包的SHA-1证书指纹：

A） 进入android Studio中的Gradle/：app/Tasks/android/signingReport并生成报告。从版本变体复制SHA1指纹

B） 如果您的应用程序由Google Play签名，请转到Google Play控制台中的发布管理/应用程序签名，并从应用程序签名证书复制SHA-1证书指纹

然后转到Firebase控制台中的“项目设置”并添加新指纹，这样就可以同时获得调试和发布指纹

步骤3

下载google-services.json文件，并用刚下载的文件替换构建中现有的文件。构建并签署新版本。

您的代码在许多方面与中包含的代码不同。与调试方法相比，更新代码以匹配示例应用可能更容易。您找到解决方案了吗？我也面临同样的问题不幸的是没有我自己的登录系统：）
