Google登录片段返回RESULT_CANCELED [英] Google sign-in fragment returning RESULT_CANCELED
问题描述
我正在尝试使用Firebase将Google登录集成到我的android应用中，但是遇到了问题.我正在此处进行教学，我相信我遵循了这个词.我将Firebase添加到我的应用中，添加了SHA-1指纹，启用了Google登录，并将依赖项添加到了成绩文件中.然后，我将代码复制到了本教程中链接到的github项目中.但是，当我运行该应用程序且代码在下面时，登录片段返回时出现错误，结果代码为RESULT_CANCELED.这是错误输出:
I am trying to integrate Google sign-in into my android app using Firebase, but I am running into issues. I am following the tutorial here, and I believe that I have followed it to the word. I added Firebase to my app, added my SHA-1 fingerprint, enabled Google sign-in, and added the dependencies to my grade files. Then, I copied the code in the github project linked to in the tutorial. However, when I run the application, and my code is below, I get an error when the sign-in fragment returns, and the result code is RESULT_CANCELED. This is the error output:
W/GoogleSignInActivity: Google sign in failed, resultCode: 0
com.google.android.gms.common.api.ApiException: 10:

创建SHA-1指纹时，确实必须使用命令重新创建~/.android/debug.keystore上的调试密钥库
When I created the SHA-1 fingerprint, I did have to remake the debug keystore at ~/.android/debug.keystore using the command
keytool -genkey -v -keystore ~/.android/debug.keystore -storepass android -alias androiddebugkey -keypass android -dname "CN=Android Debug,O=Android,C=US"
然后我使用命令将密钥库转换为pkcs12
and then I converted the keystore to pkcs12 using the command
keytool -importkeystore -srckeystore ~/.android/debug.keystore -destkeystore ~/.android/debug.keystore -deststoretype pkcs12
我从未使用过Firebase或Google登录进行身份验证，所以我很迷路.我认为密钥库可能是问题所在，当我在File > Project Structure > Signings中查看时，左侧面板中没有任何显示，并且在File > Project Structure > Build Types中，签名配置"框为空.同样，我对Firebase和Google身份验证还很陌生，因此，如果我忘记了一些简单的内容，请原谅.预先感谢您的帮助.
I have never used Firebase or Google sign-in for authentication, so I am very lost. I think the keystore might be the problem, and when I look in File > Project Structure > Signings nothing is shown in the left panel, and in File > Project Structure > Build Types the Signing Config box is empty. Again, I am very new to Firebase and Google authentication, so please excuse me if I'm forgetting something simple. Thank you in advance for your help.
这是我主要活动的代码.布局只是一个Google登录按钮和操作栏.
This is the code for my main activity. The layout is simply a Google sign-in button and the action bar.
