如何在Android中通过彩信发送图像？ [英] How to send image via MMS in Android?

问题描述

我工作的多媒体应用程序。我拍摄一张图像通过摄像头和要发送的图像与文字为其它数字。但我没有得到如何通过彩信发送图像。

I am working on a multimedia application. I am capturing one image through the camera and want to send that image with a text to some other number. But I am not getting how to send the image via the MMS.

推荐答案

彩信仅仅是一个HTTTP-post请求。您应使用执行请求的额外的网络功能的：

MMS is just a htttp-post request. You should perform the request using extra network feature :

final ConnectivityManager connMgr = (ConnectivityManager)context.getSystemService(Context.CONNECTIVITY_SERVICE);
final int result = connMgr.startUsingNetworkFeature( ConnectivityManager.TYPE_MOBILE, Phone.FEATURE_ENABLE_MMS);

如果您得到结果与Phone.APN_REQUEST_STARTED价值，你必须等待合适的状态。注册BroadCastReciver，等到Phone.APN_ALREADY_ACTIVE出现：

If you get result with Phone.APN_REQUEST_STARTED value, you have to wait for proper state. Register BroadCastReciver and wait until Phone.APN_ALREADY_ACTIVE appears:

final IntentFilter filter = new IntentFilter();
filter.addAction(ConnectivityManager.CONNECTIVITY_ACTION);
context.registerReceiver(reciver, filter);

如果连接的背景已准备就绪，建设内容和实施要求。如果你想这样做，使用Android的内部code，请使用此：

If connection background is ready, build content and perform request. If you want to do that using android's internal code, please use this:

final SendReq sendRequest = new SendReq();
    final EncodedStringValue[] sub = EncodedStringValue.extract(subject);
    if (sub != null && sub.length > 0) {
        sendRequest.setSubject(sub[0]);
    }
    final EncodedStringValue[] phoneNumbers = EncodedStringValue
            .extract(recipient);
    if (phoneNumbers != null && phoneNumbers.length > 0) {
        sendRequest.addTo(phoneNumbers[0]);
    }

    final PduBody pduBody = new PduBody();

    if (parts != null) {
        for (MMSPart part : parts) {
            final PduPart partPdu = new PduPart();
            partPdu.setName(part.Name.getBytes());
            partPdu.setContentType(part.MimeType.getBytes());
            partPdu.setData(part.Data);
            pduBody.addPart(partPdu);
        }
    }

    sendRequest.setBody(pduBody);

    final PduComposer composer = new PduComposer(this.context, sendRequest);
    final byte[] bytesToSend = composer.make();

    HttpUtils.httpConnection(context, 4444L, MMSCenterUrl,
            bytesToSendFromPDU, HttpUtils.HTTP_POST_METHOD, !TextUtils
                    .isEmpty(MMSProxy), MMSProxy, port);

MMSCenterUrl：URL从彩信的APN，MMSProxy：由彩信的APN，代理端口：端口从彩信的APN

MMSCenterUrl: url from MMS-APNs, MMSProxy: proxy from MMS-APNs, port: port from MMS-APNs

请注意，某些类是内部的包。下载从Android的Git是必需的。

Note that some classes are from internal packages. Download from android git is required.

请求应使用URL从用户的APN空间... code做..：

The request should be done with url from user's apn-space...code..:

public class APNHelper {

public class APN {
    public String MMSCenterUrl = "";
    public String MMSPort = "";
    public String MMSProxy = ""; 
}

public APNHelper(final Context context) {
    this.context = context;
}   

public List<APN> getMMSApns() {     
    final Cursor apnCursor = this.context.getContentResolver().query(Uri.withAppendedPath(Telephony.Carriers.CONTENT_URI, "current"), null, null, null, null);
if ( apnCursor == null ) {
        return Collections.EMPTY_LIST;
    } else {
        final List<APN> results = new ArrayList<APN>(); 
            if ( apnCursor.moveToFirst() ) {
        do {
            final String type = apnCursor.getString(apnCursor.getColumnIndex(Telephony.Carriers.TYPE));
            if ( !TextUtils.isEmpty(type) && ( type.equalsIgnoreCase(Phone.APN_TYPE_ALL) || type.equalsIgnoreCase(Phone.APN_TYPE_MMS) ) ) {
                final String mmsc = apnCursor.getString(apnCursor.getColumnIndex(Telephony.Carriers.MMSC));
                final String mmsProxy = apnCursor.getString(apnCursor.getColumnIndex(Telephony.Carriers.MMSPROXY));
                final String port = apnCursor.getString(apnCursor.getColumnIndex(Telephony.Carriers.MMSPORT));                  
                final APN apn = new APN();
                apn.MMSCenterUrl = mmsc;
                apn.MMSProxy = mmsProxy;
                apn.MMSPort = port;
                results.add(apn);
            }
        } while ( apnCursor.moveToNext() ); 
             }              
        apnCursor.close();
        return results;
    }
}

private Context context;

}
