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 below for reference. Thanks in advance!
private static boolean downloadThroughGateway(Context context, String host,
String port, String urlMms) throws Exception {
URL url = new URL(urlMms);
// Set-up proxy
if (host != null && port != null && host.equals("") && !port.equals("")) {
Log.d(TAG, "[MMS Receiver] Setting up proxy (" + host + ":" + port
+ ")");
Properties systemProperties = System.getProperties();
systemProperties.setProperty("http.proxyHost", host);
systemProperties.setProperty("http.proxyPort", port);
systemProperties.setProperty("http.keepAlive", "false");
}
// Open connection
HttpURLConnection connection = (HttpURLConnection) url.openConnection();
// Disable cache
connection.setUseCaches(false);
// Set the timeouts
connection.setConnectTimeout(TIMEOUT);
connection.setReadTimeout(TIMEOUT);
// Connect to the MMSC
Log.d(TAG, "[MMS Receiver] Connecting to MMS Url " + urlMms);
connection.connect();
try {
Log.d(TAG,
"[MMS Receiver] Response code is "
+ connection.getResponseCode());
if (connection.getContentLength() >= 0) {
Log.d(TAG, "[MMS Receiver] Download MMS data (Size: "
+ connection.getContentLength() + ")");
byte[] responseArray = new byte[connection.getContentLength()];
DataInputStream i = new DataInputStream(
connection.getInputStream());
int b = 0;
int index = 0;
while ((b = i.read()) != -1) {
responseArray[index] = (byte) b;
index++;
}
i.close();
// Parse the response
MmsDecoder parser = new MmsDecoder(responseArray);
parser.parse();
byte[][] imageBytes = new byte[parser.getParts().size()][];
for (int j = 0; j < parser.getParts().size(); j++) {
imageBytes[j] = parser.getParts().get(j).getContent();
}
// Insert into db
// Uri msgUri = MmsHelper.insert(context, parser.getFrom(),
// parser.getSubject(), imageBytes);
// ContentValues updateValues = new ContentValues();
// updateValues.put("read", 0);
// context.getContentResolver().update(msgUri, updateValues,
// null,
// null);
// Close the connection
Log.d(TAG, "[MMS Receiver] Disconnecting ...");
connection.disconnect();
System.gc();
// Callback
// if (bi != null)
// bi.onReceiveMms(context, msgUri);
return true;
}
// Close the connection
Log.d(TAG, "[MMS Receiver] Disconnecting ...");
connection.disconnect();
} catch (Exception e) {
e.printStackTrace();
}
return false;
}
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);

I have a program in which I'm trying to download the content of an image file from a server. I'm using java socket to download it. After downloading, I use BitmapFactory.decodeByteArray() to create a bitmap.
At the server side, the file is a .jpg file and it's only about 180 KBytes, so I don't need to try scaling it. I can see through logs that the exact number of bytes in the file is received by my image download code. I store all the bytes in a byte[] array and then convert it into a bitmap.
The imageView is initially hidden and then supposed to be made visible after populating the image. But using BitmapFactory.decodeByteArray() is returning null always. I did see some other posts about null bitmap, but nothing seems to have an answer for this problem.
I don't want to use any external library just for this, so please do not give me suggestions to try out some other libraries. Can someone spot any problem with the code? The server side program is also mine and I know that part is correct because using that, browsers are able to download the same image file. I have copy-pasted it below.

I was making a mistake, assuming that a .jpg file's bytes can be directly decode with the android bitmap decoder. Apparently this is not the case. So, I wrote the received bytes into a temporary file in the phone storage and then called BitmapFactory.decodeFile() which is able to return a good bitmap and ends up showing the image.
So, have a working solution now.
Still - if anyone has a better suggestion how to decode directly from the received bytes (which are from a .jpg file), I would be very interested to try it out since that would be more efficient. Thanks.

This hasn't been reported on any other phone.. I would use HttpURLConnection But it doesn't support Digest Authentication (which is currently what our frapi server is using)
I'm just not sure if there's any way to continue using the authentication mechanism we have or if I have to implement a different protocol in frapi (hopefully without breaking all of our existing applications..) or if there is another way to bypass this issue for the folks with these phones? This issue is pretty restricted (one client who has about 10 phones, not the end of the world, but definitely a major issue for them)
Is there anything in android that I can do to resolve this kind of problem for the affected users? Does it seem like the code is incorrect?
It is possible to use DigestAuth with HttpUrlConnection:
private InputStream connect(String urlStr, String username, String password) throws Exception {
URL url = new URL(urlStr);
HttpURLConnection connection = (HttpURLConnection) new URL(urlStr).openConnection();
connection.setDoInput(true);
connection.setRequestMethod("GET");
try {
return connection.getInputStream();
} catch(Exception e) {
if (connection.getResponseCode() == 401) {
String header = connection.getHeaderField("WWW-Authenticate");
String uri = new URL(urlStr).getFile();
String nonce = Tools.match(header, "nonce=\"([A-F0-9]+)\"");
String realm = match(header, "realm=\"(.*?)\"");
String qop = match(header, "qop=\"(.*?)\"");
String algorithm = match(header, "algorithm=(.*?),");
String cnonce = generateCNonce();
String ha1 = username + ":" + realm + ":" + password;

I ran into a similar issue today and just started using HttpClient for Android
Added dependency compile 'org.apache.httpcomponents:httpclient-android:4.3.5.1' to build.gradle.
Replace new DefaultHttpClient() with HttpClientBuilder.create().build()
There are probably some other minor refactors you might need to make in other portions of the code, but that should be pretty straight forward.
I have an Android app that posts to a web service via the code below and it all works fine. But the myContract method in the service returns a Boolean, true or false. How do I retrieve that value so I can tell my app to move on or not if false?
HttpPost request = new HttpPost(SERVICE_URI + "/myContract/someString");
request.setHeader("Accept", "application/json");
request.setHeader("Content-type", "application/json");
DefaultHttpClient httpClient = new DefaultHttpClient();
HttpResponse response = httpClient.execute(request);
Edit
Sorry about the edit, but using HttpResponse, and then logging or toasting response.toString() returns a string I don’t understand!
Update
Thanks Shereef,
But that seems like a bit too much information and code to do what I was trying to do. I have added some code below that works but I’m not sure if it’s right. The service will return a Boolean true or false as to whether or not the POST was successful, but I seem to be retrieving it as a string!
HttpEntity responseEntity = response.getEntity();
char[] buffer = new char[(int)responseEntity.getContentLength()];
InputStream stream = responseEntity.getContent();
InputStreamReader reader = new InputStreamReader(stream);
reader.read(buffer);
stream.close();
JSONObject jsonResponse = new JSONObject(new String(buffer));
String ServiceResponse = jsonResponse.getString("putCommuniqueResult");
Log.d("WebInvoke", "Saving : " + ServiceResponse);
Is this ok? It works but I’m not sure if its right!
Cheers,
Mike.

let's say this url makes your service shows it's output
http://google.com/wcfsvc/service.svc/showuserdata/11949
public boolean isWSTrue() {
String data = connectGET("google.com",
"wcfsvc", "service.svc",
"showuserdata/11949", null);
if(null != data && data.length() >0)
return data.toLowerCase().contains("true");
throw new Exception("failed to get webservice data");
}
Note: that within this case you do not actually need to parse the JSON or XML if only checking for boolean then you know if you found true it's true if found anything else it's false.
if you need to get data using XML or JSON you can refer to this answer https://stackoverflow.com/a/3812146/435706
I'm having a big issue with a static HTTPS connection method. Every second request fails and HttpsUrlConnection.getResponseCode() returns -1. So every second call works well, returning data as expected.
It's the method of a static class I'm using in different corners of my application. I would guess there is anything I don't clean up correctly when the method returns the first time and that whatever causes a problem might get destroyed through a second call of the method. But I'm having a hard time finding any clues.
I'm currently using this class to talk to hosts with invalid SSL certificates. Not going to use this in the final version of the app, but right now I need to save money. ;)
