POReading data from a Socket in android
text
Body
copied!<p>I'm getting mad trying to read data from a socket. I tried all and all, I think that my code should work but didn't.</p> <p>My intention is to only run the following method on the onCreate. First I create a Thread to run all the things that are related to the network. Then, I create the scoket object and I read the inputstream of the socket. In this moment, in an infinit loop, I read the inputstream using readLine as explained saw on <a href="https://stackoverflow.com/a/2549222/1382141">this answer</a>. Finally, I do what I want with the data that came by the socket.</p> <p>I don't know how much data will be sended by the server. And it would be in json, but this doesn't matter.</p> <p>Here my code</p> <pre><code>public void receiveMsgs(){ new Thread(new Runnable(){ @Override public void run() { BufferedReader in = null; try { Log.d("NETWORK-RECEIVE", "Trying to connect to socket..."); Socket socket; InetAddress serverAddr = InetAddress.getByName(SERVER_IP); socket = new Socket(serverAddr, SERVERPORT); in = new BufferedReader(new InputStreamReader(socket.getInputStream())); if(socket.isConnected()){ Log.d("NETWORK-RECEIVE", "The connection have been stablished"); } } catch (IOException e) { e.printStackTrace(); Log.d("NETWORK-RECEIVE", "Something goes wrong: IOException"); } while(true){ String msg = null; try { StringBuilder total = new StringBuilder(); String line; while ((line = in.readLine()) != null) { total.append(line); } msg = total.toString(); Log.d("NETWORK-RECEIVE","Message readed!:"+msg); } catch (IOException e) { e.printStackTrace(); Log.d("NETWORK-RECEIVE", "Something goes wrong: IOException"); } if(msg == null){ Log.d("NETWORK-RECEIVE", "Message is null"); break; } else{ //Do what I want Log.d("NETWORK-RECEIVE", "something"); } } } }).start(); } </code></pre>
