Hi there I have 2 classes in order to push a file into an android device.
My Server CLass:
public class FileServer {
public static void main (String [] args ) throws IOException {
// create socket
ServerSocket servsock = new ServerSocket(13267);
while (true) {
System.out.println("Waiting...");
Socket sock = servsock.accept();
System.out.println("Accepted connection : " + sock);
// sendfile
File myFile = new File ("C:\\Users\\Petrica\\Desktop\\zzz.txt");
byte [] mybytearray = new byte [(int)myFile.length()];
FileInputStream fis = new FileInputStream(myFile);
BufferedInputStream bis = new BufferedInputStream(fis);
bis.read(mybytearray,0,mybytearray.length);
OutputStream os = sock.getOutputStream();
System.out.println("Sending...");
os.write(mybytearray,0,mybytearray.length);
os.flush();
sock.close();
}
}
}
And my Client Class:
public class TCPClient extends AsyncTask{
#Override
protected Object doInBackground(Object... params) {
int filesize=6022386; // filesize temporary hardcoded
long start = System.currentTimeMillis();
int bytesRead;
int current = 0;
// localhost for testing
Socket sock = null;
try {
sock = new Socket("127.0.0.1",13267);
} catch (UnknownHostException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
} catch (IOException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}
System.out.println("Connecting...");
// receive file
try {
byte [] mybytearray = new byte [filesize];
InputStream is = sock.getInputStream();
FileOutputStream fos = new FileOutputStream("/mnt/sdcard/zzz.txt");
BufferedOutputStream bos = new BufferedOutputStream(fos);
bytesRead = is.read(mybytearray,0,mybytearray.length);
current = bytesRead;
// thanks to A. Cádiz for the bug fix
do {
bytesRead =
is.read(mybytearray, current, (mybytearray.length-current));
if(bytesRead >= 0) current += bytesRead;
} while(bytesRead > -1);
bos.write(mybytearray, 0 , current);
bos.flush();
long end = System.currentTimeMillis();
System.out.println(end-start);
bos.close();
sock.close();
// TODO Auto-generated method stub
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return null;
}
}
I get an error

super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);

Does anyone have an idea what should I do ??? In the future i would like to send 2 files :D .Thanks in advice .
You're really expected to be able to sort out your own NullPointerExceptions: at least I expect it, but when you get past that, your copy code is wrong. You are presently ignoring the count returned by read() and assuming it fills the buffer. It isn't guaranteed to do that. See the Javadoc.
while ((count = in.read(buffer)) > 0)
{
out.write(buffer, 0, count);
}
Use this at both ends, with any buffer size > 0, typically 8192.
I don't think your Socket is connecting, but its hard to tell. IN your log output, it says NullPointerException caused by doInBackground() line 33. You should check line 33 in your editor, and better yet, show us in your post which line is 33. I kind of have a feeling that you call Socket sock = null;, then you try and instantiate a new Socket in a try block, but that fails, so sock still == null, then you call a method on sock, and boom, NPE.
If you are running the Server on a computer, and the AsyncTask on an Android device, you won't be able to try and connect to localhost (127.0.0.1). You should instead try to connect to the internal network ip of your computer (something like 192.168.1.XXX), assuming both devices are on WiFi. If you are running an android emulator, then 127.0.0.1 refers back to the emulated device, and all emulator sessions run on an emulated router that you will have to configure for port forwarding before you can refer to the development machine, see here-->http://developer.android.com/tools/devices/emulator.html#emulatornetworking
As Andras Balazs Lajtha says, it looks like TCPClient isn't ever initialized/created during onCreate(), it is only declared. Since your logcat output shows errors from TCPClient though, I assume you have that code actually running.
In general, when you post a log output that refers to problems with a specific line of code, you should start there, and when you post, tell us or show us which line that is. And of course, if line 33 isn't related to a null Socket object, then I haven't been much help at all :)

Can I do?
You are attempting to show a dialog in a background thread. Only the main UI thread may show dialogs and touch the UI otherwise.
To post a Runnable to the main UI thread handler, you can use runOnUiThread() in an activity.
This is my code:
public void connect() {
// address is public variable
BluetoothDevice device = myBluetoothAdapter.getRemoteDevice(address);
try {
btSocket = createBluetoothSocket(device);
} catch (IOException e1) {
}
myBluetoothAdapter.cancelDiscovery();
// Establish the connection. This will block until it connects.
try {
btSocket.connect();
connesso = true;
} catch (IOException e) { //here I have exception
try {
btSocket.close();
connesso = false;
} catch (IOException e2) {}
}
if(connesso){
mConnectedThread = new ConnectedThread(btSocket);
mConnectedThread.start();
}
}
private BluetoothSocket createBluetoothSocket(BluetoothDevice device) throws IOException {
BluetoothSocket socket = null;
if (Build.VERSION.SDK_INT >= 10) {
try {
socket = device.createInsecureRfcommSocketToServiceRecord(MY_UUID);
Method m = device.getClass().getMethod("createInsecureRfcommSocket", new Class[] {int.class});
socket = (BluetoothSocket) m.invoke(device, Integer.valueOf(1));
} catch (Exception e) {
System.out.println(e);
}
}
return socket;
}
I have a problem when I try to connect my physical device to my server using sockets. On the server side it does not seem to accept any connection while on the client side the socket times out. Any ideas why this is happening?
I provide my code below
Server Code:
public void run()
{
// TODO Auto-generated method stub
try{
gamePending = false;
pid = 0;
while(pid < 2){
System.out.println("Hello from run loop on game");
Socket tempSocket = server.accept();
System.out.println("Client connected at " + tempSocket.getLocalPort());
PrintWriter tempWriter = new PrintWriter(new BufferedWriter (new OutputStreamWriter(tempSocket.getOutputStream())),true);
tempWriter.println("" + pid);
players[pid] = new Client(tempSocket, pid, this);
players[pid].start();
gamePending = true;
if(pid == 0){sendMsg(pid, "waiting for other player");}
pid++;
}
}
catch(Exception e){
System.out.println("There has been an Error. Game will be Terminated.");
}
//Start new game for the next two players...
new Game();
}
Client Side:
public void run() {
// Connects to the Server....
try {
socket = new Socket("192.168.1.116", 9090);
} catch (UnknownHostException e) {
// TODO Auto-generated catch block

} catch (IOException e) {

I can't be sure (because it does not appear in your code) but I think the server is not hosing on the same port (9090). That may be the main problem, but the server or client may also be blocked by a firewall (even if they run on the same machine).
I have a thread class when I start the thread and create the instance of thread class in the main class my app get crash. My main activity code for creating the thread is:
broadcast broadcastobject=new broadcast(messages);

public class broadcast extends Thread {

According to the logcat, the code is crashing at line 43 with a Null Pointer Exception, and I can't tell which line 43 is. However:
Have you checked that Environment.getExternalStorageDirectory().getAbsolutePath() is returning non null? It maybe that there is no external storage directory, or you don't have permission to know about it.
It is also worth reading the developer pages, http://developer.android.com/reference/android/os/Environment.html#getExternalStorageDirectory(), which note that you shouldn't write to that directory, which you seem to be doing.
I solved this problem by myself. There was error in static variable who was changing his value due to logical error in code.
I am writing an application that communicates using sockets. I have a server running on one android emulator on a computer, then i have 2 other clients running on android emulators on 2 other computers. I am trying to get the 2 clients to connect to the server.
This works when i run the server and clients on the same computer, but when i attempt to do this on the same wifi network and on separate computers it gives me the following error. The client and server code is posted below. A lot is stripped out just to show the important stuff. Also, after the server starts i telnet into the server and run these commands redir add tcp:5000:6000 (i have also tried without doing the redir but it still says the same thing). Then i start the clients and get the error. Thanks for the help!
Both the 5000 port and 6000 port are open on my router. And i have windows firewall disabled on the computer hosting the server.
