将文件上传到Android中的Google驱动器（自有帐户）？

Question

我在android中拥有自己的帐户google-drive实现。我必须完成授权过程（https://developers.google.com/drive/web/service-accounts），然后尝试将文件上传到Google云端硬盘。一些使用令牌上传它的教程。但我不知道从哪里获取token_id来驱动＆＃34; Drive＆＃34;。我是android开发的新手，所以。如果有任何想法，请告诉我。

先谢谢

我试过这个：

                  {
                        System.out.println("HARDCODE CREDENTIALS here");
                           credential = new GoogleCredential.Builder()
                              .setTransport(httpTransport)
                              .setJsonFactory(jsonFactory)
                              .setServiceAccountId(SERVICE_ACCOUNT_EMAIL)

                Drive service = new Drive.Builder(httpTransport, jsonFactory, null)
                      .setHttpRequestInitializer(credential)
                      .setApplicationName("Sample Owned Account")
                      .build();



 final File body = new File();
                body.setTitle("My document");
                body.setDescription("A test document saf hkfhflkhs;lkhlf h;ls;afhsa;lk");
                body.setMimeType("text/plain");

                            File file = service.files().insert(body, mediaContent).execute();
                            System.out.println("File ID: " + file.getId());
                        } catch (Exception e) {

                thread.start();
