android - Google登录+ Youtube数据Api问题

Question

以下代码演示了一种情况，用户可以使用google帐户登录，该授权代码被检索并用于使用oAuth2同时查询youtube数据api以获得一些数据。这是使用tokenResponses和GoogleCredential完成的，如下面的代码所示。通过异步任务“ALLYOUTUBE”处理。

当我使用一个帐户登录->(imageview更改为youtube个人资料图片)->然后注销，使用第二个帐户登录->(imageview更改为youtube个人资料pic)->然后注销时，就会出现问题。 现在出现问题，我再次使用第一个帐户登录，状态textview更改为代表Google登录帐户名，而通过Youtube API提取的个人资料图片仍然与以前的帐户相同，无论是什么某些原因，YouTube API仍然认为我已使用第二个帐户登录。

为了测试以下内容，我建议使用此GITHUB项目https://github.com/googlesamples/google-services/tree/master/android/signin

因此，经过大量的研究和调试，将其范围缩小到代码中最无辜的参与者 Youtube Request Builder ，这显然会引起整个证书管理问题，为避免这种情况，我只需切换
以下代码

        builder = new YouTube.Builder(httpTransport , jsonFactory,credential)
            .setApplicationName("TubeManager");

    this.yaoutube = builder.build();

    YouTube.Channels.List query;
    try {
        query = this.yaoutube.channels().list("snippet").setMine(true);
        listResponse = query.execute();
    } catch (IOException e) {
        e.printStackTrace();
    }

与

        OkHttpClient client = new OkHttpClient();
        try {
            Request request = new Request.Builder()
                    .url("https://www.googleapis.com/youtube/v3/channels?part=snippet&mine=true&maxResults=10")
                    .addHeader("Authorization", String.format("Bearer %s", credential.getAccessToken()))
                    .build();

            Response response = client.newCall(request).execute();
            String jsonBody = response.body().string(); 

       // jsonBody is the Required json response , parse this and use

        } catch (IOException e) {
            e.printStackTrace();
        } catch (GoogleAuthException e) {
            e.printStackTrace();
        }

GOOGLE请修复您的youtube生成器，我的时间花了很多时间。

就像一个聪明人曾经说过的(我自己:3)，问题的根源(与代码有关!)总会出现在您最不希望发生问题的地方
