I am trying to send files over my android app with smack library 4.1.1, though i am having some errors to do so. The thing is that i don't know why it just sends the files to a device but after that it doesn't let me to send to others and others can't send to others either, for example the first time i opened a listener with one device, that device could and can still send files just to one device (the first that it sent) but the one that receives can not, the file seems to arrive but with 0 data or maybe it doesn't arrive and just when arrives something causes error i am not sure but after a while i don't know if the connection or something breaks and i can send files with any other device but not with another, just one. and the others gets this error:
I also test it with spark and i can receive files perfectly from spark even though when i send a file to spark it shows error on spark also.

it is really wierd, i dont really know what i am doing wrong. look at my code
SEND FILE:
public static void sendFile(String Username, String filePathAndName, AbstractXMPPConnection connection){
Log.e("FILENAMEing file", "to " + Environment.getExternalStorageDirectory() + File.separator + Example.DB_FOLDER + File.separator + "myText.jpg");
Log.e("FILENAMEing file", "to " + Username);
FileTransferManager manager = FileTransferManager.getInstanceFor(connection);
OutgoingFileTransfer transfer = manager.createOutgoingFileTransfer(Username + Example.DOMAIN + "/" + Example.APP_NAME);
try {
transfer.sendFile(new File(filePathAndName), "This is a Test!");
} catch (SmackException e) {
e.printStackTrace();
}
}
RECEIVING FILES:
public static void setFileTransferListener(AbstractXMPPConnection connection){
FileTransferManager manager = FileTransferManager.getInstanceFor(connection);
// Create the listener
manager.addFileTransferListener(new FileTransferListener() {
@Override
public void fileTransferRequest(FileTransferRequest request) {
IncomingFileTransfer transfer = request.accept();
try {
File file = new File(Environment.getExternalStorageDirectory() + File.separator + Example.DB_FOLDER + File.separator + "myFile22.jpg");
transfer.recieveFile(file);
} catch (SmackException | IOException e) {
e.printStackTrace();
}
}
});
}
I would love to read any answer or hint. I am stuck on this for 2 days D: i really need help :/.
The port is forwarded ofcures like i said it works with one device or the first deviced that open a listener first i think.
I hope this helps anyone, the api works fine even though we need to change some properties in our openfire server:
1. xmpp.proxy.enabled – true
2. xmpp.proxy.port – 7777 (7777 is the default but could be another)
3. xmpp.proxy.externalip – (host or ip)
At the time it is working very well, need to make more tests though, I am wrong please someone provide any other info to fix this.
