Firebase登录:GoogleSignIn onActivityResult()返回RESULT_CANCELED，结果错误12500 [英] Firebase Sign In: GoogleSignIn onActivityResult() returns RESULT_CANCELED with Result error 12500

问题描述

好吧，我知道这个问题已经被问过多次了，但是由于某种原因，这个错误一直在发生，这是这种情况:

Ok, i am aware that this question has been asked multiple times, but for some reason this error keeps happening, this is the scenario:

• 创建的PROD firebase项目，在运作良好的Android项目(Android项目路径:app/google-services.json)中插入了google-services.json，其中包含:

• Created PROD firebase project, inserted google-services.json within Android project (Android project path: app/google-services.json) that is working perfectly, contains:

1. 两个SHA1密钥-来自.android/debug.keystore(目前为)和自定义发布密钥库(基于这些密钥的2个Oauth2 Android客户端ID)
2. 用于Google登录的Oauth2 Web客户端ID-我已将其放入Firebase控制台/身份验证/提供程序/Google登录/Web SDK配置中
3. Firebase项目ID为com.companyname.projectname格式

然后我创建了DEV firebase项目(app/debug/google-services.json)，并完成了以下操作:

Then I created DEV firebase project (app/debug/google-services.json) and i've done the following:

1. 创建自定义调试密钥库，导出SHA1并将其添加到Firebase项目中(该密钥库用于签名调试)
2. 在build.gradle内，已将此调试密钥库分配给调试构建类型，并且可以正常工作-正在使用该密钥库对其进行签名
3. 创建了新的Oauth2 Web客户端ID，并以与PROD for Google登录提供商相同的方式将其插入
4. 此项目的Firebase项目ID为com.companyname.projectname-dev(在构建类型debug中添加了应用程序后缀)

1. Created custom debug keystore, exported SHA1 and added It into Firebase project (That keystore is used to sign debug)
2. Within build.gradle, assigned this debug keystore to debug build type and that is working - it is being signed using that keystore
3. Created new Oauth2 Web client id and inserted it in the same way as in PROD for Google Sign in provider
4. Firebase Project ID for this project is com.companyname.projectname-dev (added application suffix within build type debug)

当我使用调试构建类型运行应用程序时，会发生以下情况:

When I run app with debug build type, this is what happens:

GoogleSignInOptions gso = new GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN)
        .requestIdToken(getString(R.string.default_web_client_id))
        .requestEmail()
        .build();

 GoogleSignInClient googleSignInClient = GoogleSignIn.getClient(this, gso);

这很好- requestIdToken 是DEV Firebase项目中的Oauth2 Web客户端ID

This is good - requestIdToken is the Oauth2 Web Client ID from DEV Firebase project

BuildConfig.APPLICATION_ID返回DEV applicationId(带-dev后缀)

BuildConfig.APPLICATION_ID returns DEV applicationId (with -dev suffix)

但是当我转到onActivityResult()时，我从该问题的标题中得到了- RESULT_CANCELED + 12500结果错误

But then when I go to onActivityResult(), i get what i get from the title of this question - RESULT_CANCELED + 12500 result error

有人遇到过同样的问题吗?

Has anyone had the same issue?

对于一个比较混乱的问题，我深表歉意，如有必要，我会添加更多信息.

My apologies for rather chaotic question, i will add more info if necessary.

注意:我曾尝试在DEV项目中使用.android/debug.keystore SHA1，但存在与上述相同的问题.

Note: I have tried using the .android/debug.keystore SHA1 within DEV project, but I had the same issue as the above.

推荐答案

我首先尝试的内容:

我想通过此错误ApiException:12500很长时间.我尝试了一切:

What I tried first :

I want through this error ApiException: 12500 for a long time. I tried everthing :

• 删除我的debugkeystore，重新创建一个
• 在Firebase控制台上添加支持电子邮件
• 更改插件的版本
• 在我的设备上更新google

但是当我浏览stackoverflow时，我找到了一个解决方案:

But when I was browsing stackoverflow, I found a solution :

我转到了此页面( https://console.developers.google.com/apis/凭据) 不要忘记在列表中选择您的项目(左上方).然后进入"Oauth同意屏幕"

I went to this page (https://console.developers.google.com/apis/credentials) Do not forget to select your project on the list (top left). Then go on "Oauth consent screen"

我几乎填写了所有字段:应用程序徽标，电子邮件支持，应用程序主页链接，应用程序隐私策略链接(以及project.firebaseapp.com)；并且我保存了.

I filled almost all the fields : the application logo, the email support, the application homepage link, application privacy policy link (with the project.firebaseapp.com); and I saved.

现在可以使用了，我可以登录.

Now it's working, I can login.

希望这会有所帮助
