Parse application/smil MMS MIME type on android
提问by toobsco42
So I have come across three categories of MMS message types:
所以我遇到了三类彩信类型：
Plain Text - "text/plain"
Plain Text - "text/plain"
Image - "image/jpeg", "image/bmp", "image/gif", "image/jpg", "image/png"
Image - "image/jpeg", "image/bmp", "image/gif", "image/jpg", "image/png"
SMIL (Synchronized Multimedia Integration Language) - "application/smil"
SMIL (Synchronized Multimedia Integration Language) - "application/smil"
So I don't have an issue grabbing the data in an MMS that falls into the first two categories. However I am having trouble grabbing the data from MMS of message type application/smil
所以我在获取属于前两类的 MMS 中的数据时没有问题。但是我无法从消息类型的 MMS 中获取数据 application/smil
Below I have included 5 different examples of application/smilMMS messages that I have pulled from my phone.
下面我列出application/smil了我从手机中提取的5 个不同的彩信示例。

How exactly do you go about parsing this type of MMS? How do other texting apps deal with different kinds of MMS's? Any help would be greatly appreciated.
你究竟是如何解析这种类型的彩信的？其他短信应用程序如何处理不同类型的彩信？任何帮助将不胜感激。

So the issue was that I was creating a Cursorlike this
所以问题是我正在创建一个Cursor这样的
Uri uri = Uri.parse("content://mms/part");
String[] projection = new String[] { "*" };
String selection = "_id = " + messageId;
Cursor cursor = mContentResolver.query(uri, projection, selection,null, null);
The problem is the selection arg should really be
问题是选择 arg 真的应该是
String selection = "mid = " + messageId;
Now my cursor contains multiple entries:
现在我的光标包含多个条目：
One entry will correspond to the SMIL file. SMIL is a file format containing xml that helps an MMS viewer to know how to display the MMS. The MIME type for this entry is application/smil if you look at the column called ct (acronym for content type)
Another entry will correspond to the text file that contains any text within that MMS besides the attachment. The MIME type of this will be text/plain
Lastly, you will find another entry that actually has the attachment. This attachment can have a variety of different MIME types depending on what the file is. If it happens to be a jpeg it will be image/jpeg, if png it will be image/png etc...
一个条目将对应于 SMIL 文件。SMIL 是一种包含 xml 的文件格式，可帮助 MMS 查看者了解如何显示 MMS。如果您查看名为 ct（内容类型的首字母缩写词）的列，则此条目的 MIME 类型为 application/smil
另一个条目将对应于包含该 MMS 中除附件之外的任何文本的文本文件。此 MIME 类型将是 text/plain
最后，您会发现另一个实际包含附件的条目。这个附件可以有多种不同的 MIME 类型，这取决于文件是什么。如果它恰好是 jpeg，它将是 image/jpeg，如果它是 png，它将是 image/png 等...
I want to thank @wnafee for pointing this out in this post Android: what to do with application/smil MIME type.
