MMS获取地址后，下载失败

Question

我已获得附件地址但下载超时。 这是我的代码。

公共类MmsSmsReceiver扩展了BroadcastReceiver {

public static final String MMS_RECEIVE_ACTION =＆＃34; android.provider.Telephony.WAP_PUSH_RECEIVED＆＃34;;

@Override
public void onReceive(final Context context, Intent intent) {
    if (intent.getAction().equals(MMS_RECEIVE_ACTION)) {
        PduParser parser = new PduParser(intent.getByteArrayExtra("data"));
        NotificationInd genericPdu = (NotificationInd) parser.parse();
        byte[] data=genericPdu.getContentLocation();
        try {
           String url=new String(data);
            Log.e("download url",url);
            final byte mms[]= HttpUtils.httpConnection(context,-1L,url,null,HttpUtils.HTTP_GET_METHOD,true, "10.0.0.172", 80);
            Log.e("download length", String.valueOf(mms.length));
        } catch (IOException e) {
            e.printStackTrace();
        }
    }

}

}
