I have to create android apps for my final project. I want to create a network tracer to trace internet flow. I've create the coding in JCreator and I've transfer it to Eclipse but it can't work. I don't know how to fix it. can anyone help me? this is my coding. package com.muo.network; import java.net.*; import java.io.*; import java.util.*; public abstract class Network{ public static void main(String[] args)throws IOException { BufferedReader stdin=new BufferedReader(new InputStreamReader(System.in)); String str; int bil; System.out.print(\n\t\t\t***NETWORK TRACER*** ); System.out.print(\n Welcome to Android Network Tracer! ); System.out.print(\n\n\n); System.out.print(\n\t\t ========\t ============== ); System.out.print(\n\t\t |1. ping |\t |2. traceroute| ); System.out.print(\n\t\t ========\t ============== ); System.out.print(\n\n); str=stdin.readLine(); bil=Integer.parseInt(str); { if(bil==1) { System.out.println(ping\n); String ip=args[0]; String pingResult = ; String pingCmd = ping + ip; System.out.print(\n\t\t You have entered: ); System.out.print(\n\t\t ===================== ); System.out.print(\n\t\t\t +ip+ ); System.out.print(\n\t\t ===================== ); System.out.print(\n); try { Runtime r = Runtime.getRuntime(); Process p = r.exec(pingCmd); BufferedReader in = new BufferedReader(new InputStreamReader(p.getInputStream())); String inputLine; while ((inputLine = in.readLine()) != null) { System.out.println(inputLine); pingResult += inputLine; } in.close(); } catch (IOException e) { System.out.println(e); } } else if(bil==2) { System.out.println(traceroute\n); String trace=args[0]; String tracertResult = ; String tracertCmd = tracert + trace; System.out.print(\n\t\t You have entered: ); System.out.print(\n\t\t ===================== ); System.out.print(\n\t\t\t +trace+ ); System.out.print(\n\t\t ===================== ); System.out.print(\n); try { Runtime r1 = Runtime.getRuntime(); Process p1 = r1.exec(tracertCmd); BufferedReader in = new BufferedReader(new InputStreamReader(p1.getInputStream())); String inputLine; while ((inputLine = in.readLine()) != null) { System.out.println(inputLine); tracertResult += inputLine; } in.close(); } catch (IOException e) { System.out.println(e); } } else { System.out.println(invalid); System.exit(0); } } } } thanks.. n sorry for my bad English.

Are you adding this to a buzztouch project or a custom project? If you're adding it to a custom project (not using buzztouch to build the app) you'll have a hard time getting help on this forum. This forum is mostly used by people working with apps they created using the online control panel here, at buzztouch.com. This also means that the majority of them don't have a deep enough understanding of the java programming language to guide you along.

oh. sorry.. but I couldn't understand buzztouch to build the app. thanxs
