Question

Problem : Can’t receive a file sent to my android app via XMPP and OpenFire Server. I can successfully send a file though. The asmack jar I am using is asmack-jse-buddycloud-2010.12.11.jar

Code :

    connConfig = new ConnectionConfiguration("beta.myCompany.co.uk", 5222);
    connConfig.setSASLAuthenticationEnabled(true);
    try {
        connect("username", "password");
    } catch (Exception e) {
        e.printStackTrace();
    }

    ServiceDiscoveryManager sdm = ServiceDiscoveryManager.getInstanceFor(connection);
    if(sdm == null)
        sdm = new ServiceDiscoveryManager(connection);

    fileTransferManager = new FileTransferManager(connection);
    FileTransferNegotiator.setServiceEnabled(connection, true);

fileTransferManager.addFileTransferListener(new FileTransferListener() {
    @Override
    public void fileTransferRequest(FileTransferRequest request) {
        IncomingFileTransfer transfer = request.accept();
        try {
            FileOutputStream fos = openFileOutput(request.getFileName(), Context.MODE_PRIVATE);
            InputStream stream = transfer.recieveFile();//THIS FAILS!
            fos.write(IOUtils.toByteArray(stream));
            fos.close();    
        } catch (Exception e) {
            e.printStackTrace();
        }
}

Error (If file is sent via Spark) :

Error in execution: — caused by:
java.util.concurrent.ExecutionException: No response from file
transfer initiator:

Error (If file is sent via Adium) :

java.util.concurrent.ExecutionException: Could not establish socket

Error (If file is sent via another instance of my app) :

Error in execution: — caused by:
java.util.concurrent.ExecutionException: — caused by: No response

My logs: (When attempting to receive file from Spark)

It appears that I am SENDING this error! (Not receiving it). Why would this be?

Answer 1

Use

transfer.receiveFile(myLocalFile);

instead of

InputStream stream = transfer.receive();

You are blocking the PacketReader thread. The first method will spawn it’s own thread to read the specific packets that make up the parts of the file being transferred. If you use the second method you have to spawn a thread of your own to do the actual file reading and writing.
