图像文件在Android的Azure移动应用中同步 [英] Image files sync in Azure Mobile Apps for Android

问题描述

很抱歉，如果这个问题不包含任何代码.我正在使用Azure移动应用程序构建一个Android应用程序.我成功地通过以下示例 TodoList . 该示例描述了数据同步的情况，但是如果我想添加对图像同步的支持怎么办?我是否必须将图像文件另存为blob到数据库中?是否将文件与db中的任何其他记录一样对待，还是有更好的方法?我必须使用移动应用"以外的服务吗?

Sorry if this question does not contain any code. I am building an Android app using Azure Mobile Apps. I am successfully following the sample with the TodoList . The sample describes the case for data sync, but what if I want to add support for images sync? Do I have to save the image files as blob inside the database? Do I treat files as any other record in the db, or is there a better way? Do I have to use a service other than "Mobile Apps"?

我还阅读了以下有关图像同步的说明，但它们似乎并不针对Android:

I've also read the following instructions about image sync, but they don't seem to target Android:

用于文件同步的程序集是预发行版本.我建议您当前自己为Android设备实现文件同步功能.要实现同步功能，建议您创建一个表来存储文件日志.表定义应该是这样的.

The assemblies used for file sync is a prerelease version. I suggest you implement the file sync feature for your Android device by yourself currently. To implement the sync feature, I suggest you create a table to store the file log. The table definition should be like this.

+-------------------+
|    Column Name    |
+-------------------+
| File name         |
| Operation type    |
| Modified date     |
+-------------------+

在设备上创建或删除文件后，我们需要向文件日志表中添加日志记录.要同步文件，我们需要比较此表上本地数据和远程数据之间的差异以同步文件.

After created or deleted the file on your device, we need to add a log record to the file log table. To sync the files, we need to compare the differences between local data and remote data on this table to sync the files.
