Android Mms Download Mms Content Through Mms Url

I am trying to download the MMS picture content through the MMS url, but it returns with a 403 (Forbidden) server response with an invalid MSISDN number. I have pasted my code belo

Solution 1:

Now I am able to find out the solution but I find that sometime the download code doesn't work but when you try again it works although what I was missing first establishing the connectivity to the server. I have mention below the connectivity method and after this call the method name downloadThroughGateway(parameters) which is mention on this question code.

private void startConnectivity() throws Exception {
        ConnectivityManager mConnMgr = (ConnectivityManager) context
                .getSystemService(Context.CONNECTIVITY_SERVICE);
        if (!mConnMgr.getNetworkInfo(ConnectivityManager.TYPE_MOBILE_MMS)
                .isAvailable()) {
            throw new Exception("Not available yet");
        }
        int count = 0;
        int result = beginMmsConnectivity(mConnMgr);
        if (result != PhoneEx.APN_ALREADY_ACTIVE) {
            NetworkInfo info = mConnMgr
                    .getNetworkInfo(ConnectivityManager.TYPE_MOBILE_MMS);
            while (!info.isConnected()) {
                Thread.sleep(1500);
                info = mConnMgr
                        .getNetworkInfo(ConnectivityManager.TYPE_MOBILE_MMS);
                Log.d(">>>", "Waiting for CONNECTED: state=" + info.getState());
                if (count++ > 5)
                    throw new Exception("Failed to connect");
            }
        }
        Thread.sleep(1500);
    }
