是否可以以编程方式访问 X-Mms-Content-Location？
我在手机上发现了一个奇怪的问题，我正在尝试找到一种方法来解决该问题以了解更多信息。
是否可以使用 Android SDK 以编程方式访问 MMS 消息中消息的 X-Mms-Content-Location 属性？
这是我正在调查的错误的一个示例。如果我可以访问该属性，那么我也许可以编写一个应用程序来修复它，以便消息检索成功。

I'm seeing a strange issue on a phone and I'm trying to come up with a way to troubleshoot it to find out more.
Is it possible to access the X-Mms-Content-Location attribute of a message from a MMS message programatically, using the Android SDK?
This is one example of the error that I am investigating. If I can access that attribute, then I may be able to code an app which repairs it so the message retrieval succeeds.

这是由数据库损坏引起的孤立事件。用户在应用程序上使用了任务杀手，从而损坏了手机存储彩信信息的数据库。
硬重置解决了这个问题。进行硬重置会重新创建文件系统和这个特定的数据库
This was an isolated incident caused by database corruption. The user had used a task-killer on the app and in doing so corrupted the phone's database which stores the MMS information.
A Hard reset took care of the problem. Doing a hard-reset re-creates the filesystem and this particular database
