android - 谷歌验证异常 : Unknown when authenticating with Cloud Endpoints

Question

我正在尝试向我的 Cloud Endpoints 添加身份验证，但无法正常工作。我使用这个博客作为指南:http://devthots.blogspot.nl/2012/07/building-awesome-android-apps-with.html

我有什么:

在 AppEngine 项目中:

@Api(name = "noteendpoint", clientIds = { "123456789012-abcdefghijklmnopqrstuvwxyz012345.apps.googleusercontent.com" }, audiences = { "my_project_id.appspot.com" }, namespace = @ApiNamespace(ownerDomain = "example.com", ownerName = "example.com", packagePath = "myapp"))
public class NoteEndpoint {
   // Rest of class, added parameter User to all methods.
}

在我的 Android 应用项目中:

Note note = new Note();     
note.setDescription("Description!");

GoogleAccountCredential credential = 
    GoogleAccountCredential.usingAudience(MainActivity.this, "my_project_id.appspot.com");
credential.setSelectedAccountName(ACCOUNT_NAME);

note.setEmailAddress(credential.getSelectedAccountName());

Builder endpointBuilder = new Noteendpoint.Builder(
    AndroidHttp.newCompatibleTransport(),
new JacksonFactory(), credential);

Noteendpoint endpoint = CloudEndpointUtils.updateBuilder(endpointBuilder).build();
Note result = endpoint.insertNote(note).execute(); // Exception thrown

当我运行它时，抛出一个 GoogleAuthException: Unknown:

我该如何解决这个问题？

用于 NoteEndpoint 类的 clientId 是从“已安装应用程序的客户端 ID”复制而来的，带有我的调试 key sha1。

使用 GoogleAccountCredential.usingAudience(MainActivity.this, "server:client_id:my_project_id.appspot.com");(因此带有 server:client_id: 前缀)不会帮助。

Answer 1

生成 Android 客户端 ID 时要小心。输入包名时，使用写在app/build.gradle中的应用ID。它可能与您的源类的包不同。

解释:

在项目创建时，您输入的包名称被 Android 用作应用程序 ID，并用于为您的源类生成包。在项目开发过程中，您可能会更改源类的包名。但要小心，Android Studio 不会自动更改您的应用程序 ID!
