    copied!<p>It seems that when I use the accept method from the Socket class the whole program freezes up until data comes through. I've passed the socket to a thread and it doesn't freeze but I need the thread to return data back which I don't think it can do.</p> <p><strong>Code For getting useername</strong></p> <pre><code>public boolean checkUsername() { NetworkIO n = new NetworkIO(); // Grabs username from edittext field username = usernameEditText.getText().toString(); System.out.println(usernameEditText.getText().toString()); // queries databse for username try { resultFromServer = n.query("username", "select username FROM user_info WHERE MATCH (username) AGAINST ('" + username + "' IN NATURAL LANGUAGE MODE);"); } catch (IOException e) { e.printStackTrace(); } } </code></pre> <p><strong>Code for NetworkIO class</strong></p> <pre><code>public class NetworkIO extends Activity { Socket networkSocket = null; PrintWriter out = null; BufferedReader in = null; public String query(String request, String fieldRequested) throws IOException { // Tries to get connection try { networkSocket = new Socket("192.168.1.8", 9009); out = new PrintWriter(networkSocket.getOutputStream(), true); in = new BufferedReader(new InputStreamReader( networkSocket.getInputStream())); System.out.println("Hi from in made"); } catch (UnknownHostException e) { System.err.println("Unknown host"); System.exit(-1); } catch (IOException e) { System.err.println("IOException"); System.exit(-1); } //Sends Request out.println(request); out.println(fieldRequested); String resultFromServer = ""; //Waits for response and if its null exit while ((in.readLine()) != null) { resultFromServer += in.readLine(); } System.out.println(resultFromServer); //Close the connections out.close(); in.close(); networkSocket.close(); return resultFromServer; } } </code></pre> <p>Any criticism of my code will be much appreciated :)</p>
