我曾提到Check progress for Upload & Download，Resumable upload using Drive API for Android和Direct and Resumable Media Uploads。
但是，我无法从中获得解决方案，并且可恢复的媒体上传始终失败。
我的测试步骤是尝试在上传过程中断开WiFi /连接到另一台WiFi，然后再次上传相同的文件，但它始终从头开始上传文件。
任何建议都表示赞赏。

似乎MediaHttpUploader没有很好地处理恢复上传。 原因是“请求上传状态”。在 Google Drive SDK Upload Files 中提到的始终无法获得Content-Range。
所以，解决它的方法是在上传过程中一直轮询Content-Range。 因此，它可以通过“从上次停止的位置恢复上传来恢复中断的上传。”
