hi i get the above error when a user inputs a username and password in my system on the second attempt.
here is the following code: the username and password is retrieved from two textfields and stores has Strings. The username and password than gets sent back to a server and later the server will send some data telling the user that the password is incorrect or correct.
When a user logs in succesfuly at the first attempt it works but on the 2nd attempt, the program gives me a out of memory error.
Code:public String login(String user, String pass) { String response = " "; try { String coin_cmd = "99" + "\n"+"\0"; String coin_val = "0.1" + "\n"+"\0"; String cmd1 = "100" +"\n"+"\0"; String cmd2 = "101"+"\n"+"\0"; String p = pass + "\n"+"\0"; String u = user + "\n"+"\0"; os.write(u.getBytes()); os.flush(); os.write(p.getBytes()); os.flush(); line1[0] = getResponse(); String bad = "BADLOGIN"; String status = line1[0].substring(12,20); if(status.equals(bad)) { response = bad; } else { os.write(coin_cmd.getBytes()); //get default coin value os.flush(); os.write(coin_val.getBytes()); os.flush(); os.write(cmd1.getBytes()); os.flush(); os.write(cmd2.getBytes()); os.flush(); for(int i=1;i<4;i++) { line1[i] = getResponse(); } //send balance response = line1[0]; line = response; } } catch(Exception e) { e.printStackTrace(); } //reset it for(int c=0; c<6 ;c++) { line1[c] = " "; } return response; }
Below is the canvas code. Note that p and u are the password and username data gathered from the text field
Code:line = root.login(u,p); String bad = "BADLOGIN"; if(line.equals(bad)) { Alert in = new Alert ("Error"); in.setString("Username or password is invalid"); in.setTimeout (3000); Display.getDisplay(root).setCurrent(in, this); line = ""; line1 = ""; line2 = ""; } else { //display error message Alert in = new Alert ("Logged In"); in.setString("You have succesfuly logged into the system"); in.setTimeout (3000); Display.getDisplay(root).setCurrent(in, this); loggedIn = true; logged = "Log out"; //line = ""; line1 = ""; line2 = ""; }
