通过区分在Android中MMS / SMS听众彩信和短信 [英] Differentiate MMS and SMS via MMS/SMS listeners in Android

问题描述

时有什么方法来区分彩信和短信使用MMS / SMS听者他们以前的打收件箱？

Is there any ways to differentiate MMS and SMS messages by using a MMS/SMS listener before they hit the inbox?

推荐答案

彩信的第一个指标是WAP推送的MIME类型应用程序/ vnd.wap.mms消息，这样你就可以注册接收器，用于android.provider.Telephony.WAP_PUSH_RECEIVED：

The first indicator of an MMS message is a WAP-push with the MIME-type "application/vnd.wap.mms-message", so you could register a receiver for "android.provider.Telephony.WAP_PUSH_RECEIVED":

    <receiver android:name=".SomeReceiverName"
        android:permission="android.permission.BROADCAST_WAP_PUSH">
        <intent-filter>
            <action android:name="android.provider.Telephony.WAP_PUSH_RECEIVED" />
            <data android:mimeType="application/vnd.wap.mms-message" />
        </intent-filter>
    </receiver>

要发现与否的你将不得不破解打开PDU接收的彩信：S和提取 X-MMS消息类型，其中应 M-通知-IND （按<一个href="http://www.google.com/url?sa=t&rct=j&q=wap-209-mmsencapsulation-20020105-a.pdf&source=web&cd=1&ved=0CBoQFjAA&url=http://www.openmobilealliance.org/tech/affiliates/wap/wap-209-mmsencapsulation-20020105-a.pdf&ei=htWvTsvqGpDDswadxfVz&usg=AFQjCNFrfkpNVXMxZ_ErlgUQBmqNcbROcA&cad=rja"相对=nofollow称号=WAP 209> WAP 209 ）。你也可以挑选出在X-MMS-交易-ID，其中一个认为应存放在 Telephony.Mms.TRANSACTION_ID 列中的消息提供者，如果你要链接他们稍后。

To discover whether or not its a received MMS you're going to have to crack open the PDU:s and extract the X-Mms-Message-Type, which should be m-notification-ind (as per WAP 209). You can also pick out the X-Mms-Transaction-ID, which one thinks should be stored in the Telephony.Mms.TRANSACTION_ID column in the message provider if you want to link them up later.
