Software caused connection abort when transferring File from java to android

[Amit Shef]

I'm making a program which transfers a file. In the process of this method, I'm getting the written error:

"Connection reset by peer: socket write error" and "Software caused connection abort"

The file's size which I'm transferring is 96MB.

(clientSocket is SSLSocket)

Client:

Activity_1 Class:

clientSocket = (SSLSocket) sslContext.getSocketFactory().createSocket();
                    clientSocket.connect(...);
            clientSocket.setEnabledCipherSuites(clientSocket.getSupportedCipherSuites());
                    clientSocket.startHandshake();

Activity_2 Class:

SSLSocket clientSocket = Activity_1.clientSocket;
 
final DataInputStream dis = new DataInputStream(clientSocket.getInputStream());
                int n = 0;
 
final byte[] buf = new byte[8192];
 
 
     fos = new new FileOutputStream....
 
                while ((n = dis.read(buf)) != -1) {
                                counter += n;
 
                                fos.write(buf, 0, n);
 
                                runOnUiThread(new Runnable() {
 
                                    @Override
                                    public void run() {
                                         ...
                                    }
 
                                });
                            }
 
 
            if (counter >= file_size) {
                            System.out.println("CLOSED");
 
                            fos.flush();
                            fos.close();
                            clientSocket.close();
 
  }

Error on Client:

Caused by: android.system.ErrnoException: recvfrom failed: ETIMEDOUT (Connection timed out)

What could cause this problem to occur?

Thanks in advanced.

This looks like your Android client is timing out.

You can find the timeout setting for our Socket using the getSoTimeout() method and compare that to how long your download is taking.

Thanks for replying.


My socket has already a timeout for his connection (7 seconds), but it still does not help.

[Dave Tolls]

How quickly does this timeout then?

Have you timed it (via logging possibly) from the opening of the connection in Activity_1 to the time out exception?

I set the Timeout at the beginning before I'm connecting to the socket.

For example:

socket.setSoTimeout(7000);
socket.connect(...);

I'm sorry for this inconvenience, but I don't know how to check how quickly will it timeout.
