Android : How to Send a string over wi-fi without using printwriter?

The program here shows passing a string using wi-fi. I need a solution which does not require print writer or a simple solution which helps me send two different strings while toggling the buttons
switch3.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
if (switch3.isChecked()) {
messsage = "S";
Log.d("On", "Button On" + messsage);
new Thread(new Runnable() {
public void run() {
// TODO Auto-generated method stub
try {
// client = new
// Socket(etIP.getText().toString(), port);
client = new Socket("192.168.4.1", 100);
printwriter = new PrintWriter(client
.getOutputStream(), true);
printwriter.write(messsage);
printwriter.flush();
//printwriter.close();
client.close();
} catch (UnknownHostException e) {
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}).start();
} else {
messsage = "T";
Log.d("off", "Button off " + messsage);// etMsg.getText().toString();
// etMsg.setText("");
// port = Integer.parseInt(etPort.getText().toString());
new Thread(new Runnable() {
public void run() {
// TODO Auto-generated method stub
try {
// client = new
// Socket(etIP.getText().toString(), port);
//client = new Socket("192.168.4.1", 100);
printwriter = new PrintWriter(client
.getOutputStream(), true);
printwriter.write(messsage);
printwriter.flush();
//printwriter.close();
client.close();
} catch (UnknownHostException e) {
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}).start();
}
}
});

You can send data by this way ->
try {
Socket socket = new Socket(DESTINATION_ADDRESS, DESTINATION_PORT);
// Exmp : Socket socket = new Socket("192.168.0.101", 80);
OutputStream outToServer = socket.getOutputStream();
DataOutputStream out = new DataOutputStream(outToServer);
out.writeUTF(SEND_STRING);
// Exmp : out.writeUTF("TEST");
socket.close();
} catch (Exception e) {
e.printStackTrace();
}

How to send file between device using xmpp while chat

Thanks for paying attention over the question...
I am making a XMPP chat application with the help of ejabbered and asmack_4.1 library.
I have installed a PSI client for windows to chat with the android device.
I am able to perform text chat between devices.
I am also able to send file from device to PSI client and PSI client to android device.
But the problem is to send files device to device.
I am using below code to send and receive files :
File send :
public void fileTransfer(String filenameWithPath, Bitmap thumbnail, String userId) {
// FileTransferManager manager = new FileTransferManager(connection);
FileTransferManager manager = FileTransferManager.getInstanceFor(connection);
// OutgoingFileTransfer transfer = manager.createOutgoingFileTransfer("usre2#myHost/Smack");
OutgoingFileTransfer transfer = manager.createOutgoingFileTransfer(userId + "/Admin"); // "/Good" depends on server
// OutgoingFileTransfer transfer = manager.createOutgoingFileTransfer(userId + "/Directors-iMac");
File file = new File(filenameWithPath);
try {
transfer.sendFile(file, "test_file");
} catch (SmackException e) {
e.printStackTrace();
}
while (!transfer.isDone()) {
if (transfer.getStatus().equals(FileTransfer.Status.error)) {
System.out.println("ERROR!!! " + transfer.getError());
} else if (transfer.getStatus().equals(FileTransfer.Status.cancelled)
|| transfer.getStatus().equals(FileTransfer.Status.refused)) {
System.out.println("Cancelled!!! " + transfer.getError());
}
try {
Thread.sleep(1000L);
} catch (InterruptedException e) {
e.printStackTrace();
}
}
if (transfer.getStatus().equals(FileTransfer.Status.refused) || transfer.getStatus().equals(FileTransfer.Status.error)
|| transfer.getStatus().equals(FileTransfer.Status.cancelled)) {
System.out.println("refused cancelled error " + transfer.getError());
} else {
System.out.println("Success");
}
}
File Receiving :
public void fileReciever(AbstractXMPPConnection connection) {
//**************************************
// Create the file transfer manager
final FileTransferManager managerListner = FileTransferManager.getInstanceFor(connection);
// FileTransferNegotiator.setServiceEnabled(connection, true);
FileTransferNegotiator negotiator = FileTransferNegotiator.getInstanceFor(connection);
Log.i("File transfere manager", "created");
// Create the listener
managerListner
.addFileTransferListener(new FileTransferListener() {
#Override
public void fileTransferRequest(FileTransferRequest request) {
Log.i("Recieve File", "new file transfere request new file transfere request new file transfere request");
Log.i("file request", "from" + request.getRequestor());
IncomingFileTransfer transfer = request.accept();
Log.i(RECIEVE_FILE_ALERT_DIALOG, "accepted");
try {
transfer.recieveFile(new File("/sdcard/" + request.getFileName()));
while (!transfer.isDone() || (transfer.getProgress() < 1)) {
Log.i(RECIEVE_FILE_ALERT_DIALOG, "still receiving : " + (transfer.getProgress()) + " status " + transfer.getStatus());
if (transfer.getStatus().equals(FileTransfer.Status.error)) {
// Log.i("Error file",
// transfer.getError().getMessage());
Log.i("Recieve File",
"cancelling still receiving : "
+ (transfer.getProgress())
+ " status "
+ transfer.getStatus());
transfer.cancel();
break;
}
}
} /*catch (XMPPException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}*/ catch (SmackException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}
});
//**************************************
}
Note : In fileTransfer() method, I am using below line:
OutgoingFileTransfer transfer = manager.createOutgoingFileTransfer(userId + "/Admin"); // "/Good" depends on server
I am able to send files from Android device to PSI desktop application and vice versa but i am not able to transfer files between android devices.

Unable to receive file using asmack and XMPP

I'm working on file sharing using Asmack and XMPP. I am able to send file but not able to receive file on another device. I did so much of Research and Development, found so many ways tried all of them but haven't got success. Seems I am making any small mistake, tried a lot but haven't got solution for my problem. The code I used for sending file is:
d.findViewById(R.id.btnsendphoto).setOnClickListener(
new OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
if (!filepath.equals("")) {
configureProviderManager(connection);
FileTransferNegotiator.IBB_ONLY = true;
FileTransferNegotiator.setServiceEnabled(
connection, true);
mFileTransferManager = new FileTransferManager(
connection);
String to = connection.getRoster()
.getPresence("cac6ba9dc9c6ac67#pc")
.getFrom();
final OutgoingFileTransfer transfer = mFileTransferManager
.createOutgoingFileTransfer(to);
File file = new File(filepath);
try {
configureProviderManager(connection);
transfer.sendFile(file, "test_file");
} catch (XMPPException e) {
e.printStackTrace();
}
new AsyncTask<Void, Void, Void>() {
protected void onPreExecute() {
}
#Override
protected Void doInBackground(
Void... params) {
while (!transfer.isDone()) {
if (transfer.getStatus().equals(
"Error")) {
Log.d("file transfer",
"ERROR!!! "
+ transfer
.getError());
} else if (transfer.getStatus()
.equals("Cancelled")
|| transfer.getStatus()
.equals("Refused")) {
Log.d("file transfer",
"Cancelled!!! "
+ transfer
.getError());
}
try {
Thread.sleep(1000L);
} catch (InterruptedException e) {
e.printStackTrace();
}
}
return null;
};
protected void onPostExecute(Void result) {
if (transfer.getStatus().equals(
"Refused")
|| transfer.getStatus().equals(
"Error")
|| transfer.getStatus().equals(
"Cancelled")) {
Log.i("file transfer",
"refused cancelled error "
+ transfer
.getError());
} else {
Log.i("file transfer", "Success: "
+ transfer.getFileName());
messages.add("file sent");
setListAdapter();
}
};
}.execute();
}
d.dismiss();
}
});
I am able to send file. I got this message file sent on sending side, here configureProviderManager is this
and I have tried many ways that I got on Google but I would like to mention one of those here
First is:
public void ReceiveFile() {
System.out.println("in ReceiveFile");
Thread thread = new Thread() {
public void run() {
System.out.println("in Thread");
configureProviderManager(connection);
// Create the file transfer manager
final FileTransferManager managerListner = new FileTransferManager(
connection);
FileTransferNegotiator.setServiceEnabled(connection, true);
Log.i("File transfere manager", "created");
// Create the listener
managerListner
.addFileTransferListener(new FileTransferListener() {
public void fileTransferRequest(
final FileTransferRequest request) {
Log.i("Recieve File",
"new file transfere request");
Log.i("file request",
"from" + request.getRequestor());
IncomingFileTransfer transfer = request
.accept();
Log.i("Recieve File alert dialog", "accepted");
try {
transfer.recieveFile(new File("/sdcard/"
+ request.getFileName()));
while (!transfer.isDone()
|| (transfer.getProgress() < 1)) {
Thread.sleep(1000);
Log.i("Recieve File alert dialog",
"still receiving : "
+ (transfer
.getProgress())
+ " status "
+ transfer.getStatus());
if (transfer.getStatus().equals(
Status.error)) {
// Log.i("Error file",
// transfer.getError().getMessage());
Log.i("Recieve File alert dialog",
"cancelling still receiving : "
+ (transfer
.getProgress())
+ " status "
+ transfer
.getStatus());
transfer.cancel();
break;
}
}
} catch (XMPPException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
});
}
};
thread.start();
}
Debugging this code
I am not even getting this log new file transfer request. Kindly please tell what mistake I am making and how can I correct this.

asmack file sending: transfer status = null

I am using asmack 18-0.8.9.
below is my sending file method
public void send()
{
configureProviderManager(connection);
FileTransferNegotiator.setServiceEnabled(connection, true);
FileTransferManager manager = new FileTransferManager(connection);
OutgoingFileTransfer transfer = manager.createOutgoingFileTransfer("xxxxx#jabber.ccc.de/Smack");
File file = new File("/sdcard/DCIM/Camera/1385869353956.jpg");
try {
Log.d("file sending",file.getAbsolutePath()+" "+file.getName());
configureProviderManager(connection);
transfer.sendFile(file, "test_file");
} catch (XMPPException e) {
e.printStackTrace();
}
while(!transfer.isDone()) {
if(transfer.getStatus().equals(Status.error)) {
System.out.println("ERROR!!! " + transfer.getError());
} else if (transfer.getStatus().equals(Status.cancelled)
|| transfer.getStatus().equals(Status.refused)) {
System.out.println("Cancelled!!! " + transfer.getError());
}
try {
Thread.sleep(1000L);
} catch (InterruptedException e) {
e.printStackTrace();
}
}
if(transfer.getStatus().equals(Status.refused))
System.out.println("refused " + transfer.getError());
else if( transfer.getStatus().equals(Status.error))
System.out.println(" error " + transfer.getError());
else if(transfer.getStatus().equals(Status.cancelled))
System.out.println(" cancelled " + transfer.getError());
else
System.out.println("Success");
}
Below is my receiver part
FileTransferManager manager = new FileTransferManager(connection);
manager.addFileTransferListener(new FileTransferListener() {
public void fileTransferRequest(final FileTransferRequest request) {
new Thread(){
#Override
public void run() {
IncomingFileTransfer transfer = request.accept();
Log.d("receive","file name: "+transfer.getFileName());
File root = android.os.Environment.getExternalStorageDirectory();
File dir = new File (root.getAbsolutePath() + "/download");
dir.mkdirs();
File file = new File(dir+transfer.getFileName());
try {
transfer.recieveFile(file);
} catch (XMPPException e1) {
// TODO Auto-generated catch block
}
while(!transfer.isDone()) {
try{
Thread.sleep(1000L);
}catch (Exception e) {
Log.d("receive","thread sleep"+ e.getMessage());
}
if(transfer.getStatus().equals(Status.error)) {
Log.d("error","error status"+ transfer.getError() + "");
}
if(transfer.getException() != null) {
transfer.getException().printStackTrace();
}
}
};
}.start();
}
});
I can successfully receive file from other desktop clients like psi, pidgin. When I try to send file from my android app to other desktop client or my own app installed on other phone they do not receive any XMPP message. While when I send file from other desktop client to my android app I can see XMPP message and successfully receive message.
Below is my configureProviderManager method
public void configureProviderManager() {
ProviderManager.getInstance().addIQProvider("query","http://jabber.org/protocol/bytestreams", new BytestreamsProvider());
ProviderManager.getInstance().addIQProvider("query","http://jabber.org/protocol/disco#items", new DiscoverItemsProvider());
ProviderManager.getInstance().addIQProvider("query","http://jabber.org/protocol/disco#info", new DiscoverInfoProvider());
}

Sending Pictures like WhatsApp

I have made a chatting application. I want to add photo/file sharing concept in my application same as WhatsApp. I have made the app using Xmpp/Openfire and current now I am using this function for photo sharing, but it is not all reliable :
public void sendFile(final String path, final String receiver) {
Thread thread = new Thread() {
public void run() {
ServiceDiscoveryManager sdm = ServiceDiscoveryManager
.getInstanceFor(connection);
if (sdm == null)
sdm = new ServiceDiscoveryManager(connection);
sdm.addFeature("http://jabber.org/protocol/disco#info");
sdm.addFeature("jabber:iq:privacy");
// Create the file transfer manager
FileTransferManager manager = new FileTransferManager(
connection);
FileTransferNegotiator.setServiceEnabled(connection, true);
// Create the outgoing file transfer
OutgoingFileTransfer transfer = manager
.createOutgoingFileTransfer(receiver + "/Smack");
System.out.println("Receiver of the file is "+receiver+"/smack");
Log.i("transfere file", "outgoingfiletransfer is created");
try {
OutgoingFileTransfer.setResponseTimeout(30000);
transfer.sendFile(new File(path), "Description");
Log.i("transfere file", "sending file");
while (!transfer.isDone()) {
try {
Thread.sleep(1000);
Log.i("transfere file", "sending file status "
+ transfer.getStatus() + "progress: "
+ transfer.getProgress());
if (transfer.getStatus() == Status.error) {
Log.i("transfere file", "Errorrr isss: "
+ transfer.getError());
transfer.cancel();
break;
}
} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
} catch (XMPPException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
Log.i("transfere file", "sending file done");
}
};
thread.start();
}
I want to do it same as WhatsApp or any other good means. Please suggest a good solution
Thanks
