[英]Google sign-in fragment returning RESULT_CANCELED
我正在尝试使用 Firebase 将 Google 登录集成到我的 android 应用程序中，但我遇到了问题。 我正在关注这里的教程，并且我相信我已经按照它来做。 我将 Firebase 添加到我的应用程序中，添加了我的 SHA-1 指纹，启用了 Google 登录，并将依赖项添加到我的成绩文件中。 然后，我复制了教程中链接到的 github 项目中的代码。 但是，当我运行应用程序时，我的代码如下，登录片段返回时出现错误，结果代码为RESULT_CANCELED 。 这是错误 output：
W/GoogleSignInActivity: Google sign in failed, resultCode: 0
com.google.android.gms.common.api.ApiException: 10:
at com.google.android.gms.common.internal.zzb.zzy(Unknown Source:14)

当我创建 SHA-1 指纹时，我确实必须使用命令在~/.android/debug.keystore重新制作调试密钥库
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
keytool -importkeystore -srckeystore ~/.android/debug.keystore -destkeystore ~/.android/debug.keystore -deststoretype pkcs12
我从来没有使用过 Firebase 或谷歌登录进行身份验证，所以我很迷茫。 我认为密钥库可能是问题所在，当我查看File > Project Structure > Signings时，左侧面板中没有显示任何内容，并且在File > Project Structure > Build Types中，Signing Config 框为空。 同样，我对 Firebase 和 Google 身份验证非常陌生，所以如果我忘记了一些简单的事情，请原谅。 预先感谢您的帮助。
这是我的主要活动的代码。 布局只是一个 Google 登录按钮和操作栏。

然后使用以下命令将密钥库转换为pkcs12
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 “签名”中File > Project Structure > Build Types ，左面板中没有显示任何内容，在“ File > Project Structure > Build Types ，“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。
这是我主要活动的代码。 该布局只是一个Google登录按钮和操作栏。

我使用以下代码遇到了类似的情况：
private static final int PLAY_LOGIN = 1979;
GoogleSignInOptions gso = new GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN).build();
GoogleSignInClient client = GoogleSignIn.getClient(activity, gso);
activity.startActivityForResult(client.getSignInIntent(), PLAY_LOGIN);
并尝试在该方法中获取登录结果：
@Override
public boolean onActivityResult(@NonNull Context context, int requestCode, int resultCode, Intent data) {
if (requestCode == PLAY_LOGIN) {
if (resultCode == Activity.RESULT_OK) {
Task<GoogleSignInAccount> task = GoogleSignIn.getSignedInAccountFromIntent(data);
// process successful login data here...
} else {
Toast.makeText(context, "login error!", Toast.LENGTH_LONG).show();
}
return true;
}
return false;
}
有时（并不总是可重现）返回的代码不是Activity.RESULT_OK ，而是Activity.RESULT_CANCELED - 即使我总是接受 Google 对话框中的登录选项...
所以我的代码显示了带有“登录错误”的Toast 。 这甚至导致我的应用没有通过 Google 审核流程。
为了调查这个问题，我将调试器断点放置在显示Toast的行处，然后继续重新安装我的应用程序并接受 Google 登录对话框。
然后有时会遇到断点，并且Intent具有以下mExtras值：
捆绑[{googleSignInStatus=Status{statusCode=未知状态码：12502，分辨率=null}}]
根据GoogleSignInStatusCodes上的 Google 文档，代码 GoogleSignInStatusCodes.SIGN_IN_CURRENTLY_IN_PROGRESS=12502 表示另一个登录已经在进行中：
因此，尽管在 Firebase 控制台中正确配置了所有内容，但我的回答是提醒任何遇到此问题的人。
您可能希望在代码中处理这种情况并向用户显示不同的消息，可能不是错误，而只是警告。
