My Android application is connected to the server through a socket, which is encoded in node.js. When it remains in the foreground for 15 minutes, it will lose connection to the server. Below is the code that connects sockt to the server.
public void connect() { this.connectionStatus = CONNECT_STATUS_CONNECTING; Log.v(AppConstants.DEBUG_TAG, userId + " : Connecting to Server"); if (mThread != null && mThread.isAlive()) { return; } mThread = new Thread(new Runnable() { @Override public void run() { try { Log.v(AppConstants.DEBUG_TAG, userId + " : Thread Action Started"); String secret = createSecret(); int port = (mURI.getPort() != -1) ? mURI.getPort() : (mURI.getScheme().equals("wss") ? 443 : 80); String path = TextUtils.isEmpty(mURI.getPath()) ? "/" : mURI.getPath(); if (!TextUtils.isEmpty(mURI.getQuery())) { path += "?" + mURI.getQuery(); } String originScheme = mURI.getScheme().equals("wss") ? "https" : "http"; URI origin = new URI(originScheme, "//" + mURI.getHost(), null); SocketFactory factory = mURI.getScheme().equals("wss") ? getSSLSocketFactory() : SocketFactory.getDefault(); mSocket = factory.createSocket(mURI.getHost(), port); mSocket.setKeepAlive(true); PrintWriter out = new PrintWriter(mSocket.getOutputStream()); out.print("GET " + path + " HTTP/1.1\r\n"); out.print("Upgrade: websocket\r\n"); out.print("Connection: Upgrade\r\n"); out.print("Host: " + mURI.getHost() + "\r\n"); out.print("Origin: " + origin.toString() + "\r\n"); out.print("Sec-WebSocket-Key: " + secret + "\r\n"); out.print("Sec-WebSocket-Version: 13\r\n"); if (mExtraHeaders != null) { for (NameValuePair pair : mExtraHeaders) { out.print(String.format("%s: %s\r\n", pair.getName(), pair.getValue())); } } out.print("\r\n"); out.flush(); HybiParser.HappyDataInputStream stream = new HybiParser.HappyDataInputStream(mSocket.getInputStream()); // Read HTTP response status line. StatusLine statusLine = parseStatusLine(readLine(stream)); if (statusLine == null) { Log.v(AppConstants.DEBUG_TAG, "Received no reply from server."); throw new HttpException("Received no reply from server."); } else if (statusLine.getStatusCode() != HttpStatus.SC_SWITCHING_PROTOCOLS) { throw new HttpResponseException(statusLine.getStatusCode(), statusLine.getReasonPhrase()); } // Read HTTP response headers. String line; boolean validated = false; while (!TextUtils.isEmpty(line = readLine(stream))) { Header header = parseHeader(line); if (header.getName().equals("Sec-WebSocket-Accept")) { String expected = createSecretValidation(secret); String actual = header.getValue().trim(); if (!expected.equals(actual)) { Log.v(AppConstants.DEBUG_TAG, "Bad Sec-WebSocket-Accept header value."); throw new HttpException("Bad Sec-WebSocket-Accept header value."); } validated = true; } } if (!validated) { Log.v(AppConstants.DEBUG_TAG, "No Sec-WebSocket-Accept header."); throw new HttpException("No Sec-WebSocket-Accept header."); } onConnect(); Log.v(AppConstants.DEBUG_TAG, userId + " : Thread should be connected by now"); // Now decode websocket frames. mParser.start(stream); } catch (EOFException ex) { Log.d(AppConstants.DEBUG_TAG, "WebSocket EOF!", ex); onDisconnect(0, "EOF"); } catch (SSLException ex) { // Connection reset by peer Log.d(AppConstants.DEBUG_TAG, "Websocket SSL error!", ex); onDisconnect(0, "SSL"); } catch (Exception ex) { onError(ex); } } }); Log.v(AppConstants.DEBUG_TAG, userId + " : Thread about to be started"); mThread.start(); }
anu solution to this problem?
