java - Android 应用程序 Gmail 的 OAuthentication 错误

Question

我正在尝试为 Android 上的 Gmail 构建一个客户端应用程序(我发现对此有很多问题)。

(我见过类似的问题:How to integrate Gmail Api in android app。但我的问题不在于 SHA1-Key)

我正在使用 Andorid 开发者网站中给出的链接:https://developers.google.com/gmail/api/quickstart/android

我已经基于此进行了第一个 Activity ，并且还在 Google 开发人员控制台中创建了 API 访问权限。

我正在使用 usingOAuth 来获取凭据，

mCredential = GoogleAccountCredential.usingOAuth2(
            getApplicationContext(), Arrays.asList(SCOPES))
            .setBackOff(new ExponentialBackOff());

我能够查看手机中配置的邮件 ID 列表，当我选择一个邮件 ID 时，我会调用异步服务中的方法:

public MakeRequestTask(GoogleAccountCredential credential) {
        HttpTransport transport = AndroidHttp.newCompatibleTransport();
        JsonFactory jsonFactory = JacksonFactory.getDefaultInstance();
        mService = new com.google.api.services.gmail.Gmail.Builder(
                transport, jsonFactory, credential)
                .setApplicationName("mailclient")
                .build();
    }

这只会转到异步服务中的 onCancelled() 方法并提供错误

应用尝试连接的 URL 不正确

https://console.developers.google.com/apis/api/gmail/overview?project=608941808256

我不确定我在这里做错了什么，我认为我唯一要做的就是在应用程序中的某个位置提供 API 或客户端 ID。但我不确定应该在哪里给出这些常量？

请检查您的 Gmail API 和您也使用的其他 API 是否已在 Google Developers Console 中启用。 。要启用它，请从 API 菜单中选择 Gmail API，然后如果您尚未这样做，请单击启用(如下图所示)。

此外，您可能还想检查此 GitHub post或者这个SO post .
