android - 可恢复上传(适用于 Android 或 Java 的 Google Drive SDK)

我提到了 Check progress for Upload & Download , Resumable upload using Drive API for Android和 Direct and Resumable Media Uploads .

但是，我无法从他们那里得到解决方案，可续传媒体上传总是失败。

我的测试步骤是尝试在上传过程中断开WiFi/连接到另一个WiFi，然后再次上传相同的文件，但它总是从头开始上传文件。

如有任何建议，我们将不胜感激。

最佳答案

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 中提到总是获取不到Content-Range。

所以，解决方法是在上传过程中一直轮询Content-Range。因此，它能够通过“从中断点恢复上传”来恢复中断的上传。
