Converting string to IP Address in java(android)

Question

When i convert string ("192.168.0.105") to InetAddress in java (android). I am getting "/192.168.0.105". An extra "/" is coming in InetAddress, which causes the socket not to be created.

How do i get rid of "/".

it would help if you posted the code that isn't quite doing what you want — Chris Stratton, May 17 '11 at 05:02
How do you convert? `InetAddress.getByName("192.168.0.105");` ? — Anders Lindahl, May 17 '11 at 05:05
InetAddress = serverIP=Inet4Address.getByName(ip); clientSocket = new Socket(serverIP , serverPort); — Mustehsan Ikram, May 17 '11 at 05:13

You can use getHostAddress() method of InetAddress to get host address without /.

And if you are using InetSocketAddress then use getAddress().getHostAddress() to get host ip without /.

InetAddress inetAddress = InetAddress.getByName("192.168.0.105");
System.out.println(inetAddress.getHostAddress());

InetSocketAddress address = new InetSocketAddress("192.168.0.105", 5555);
System.out.println(address.getAddress().getHostAddress());

my problem is that i need to open Socket after getting InetAddress – Mustehsan Ikram May 17 '11 at 05:18
@Mustehsan: in that case use java Socket to open and communicate through socket. Read this: http://download.oracle.com/javase/tutorial/networking/sockets/readingWriting.html and this: http://zerioh.tripod.com/ressources/sockets.html – Harry Joy May 17 '11 at 05:23
I am currently doing it. but my problem is that as InetAddress is wrong thus socket is not being created. – Mustehsan Ikram May 17 '11 at 05:59
I am getting following exception on socket creation java.net.SocketTimeoutException: Transport endpoint is not connected – Mustehsan Ikram May 17 '11 at 06:06
@Mustehsan: are you sure ip is reachable? – Harry Joy May 17 '11 at 06:27
make sure that ip is reachable and firewall has exception for that port no. i.e your allowed to connect to that port, so check firewall – Nirmal- thInk beYond May 17 '11 at 06:28
