How to find the IP Address of HTC Incredible on a CDMA Network

Question

How can I find the IP address of the an HTC incredible connected to Verizon's network? My other question - do I have to make any changes to my App to run it on a cellular network? Till now the App was running on a Nexus One connected to a local Wi-Fi network.

Thanks.

Answer 1

Through mobile network, to check your IP run the command below:

ifconfig rmnet0

or application like 'Android Status' can be handy. Get it from the market.

Answer 2

1. To get IP address info look at this example. Might need a tweak for your CDMA.

2. You need not modify anything to get it working on Mobile n/w

Answer 3

You can use NetworkInterface.getNetworkInterfaces();, then addresses = intf.getInetAddresses(); to enumerate all the IP addresses on all the interfaces. You're looking for an address associated with a PDP.

That should work. I'm currently looking for a neater way.

Answer 4

To get the internal IP Address you can use the following snippet of code:

Enumeration<NetworkInterface> networkInterfaces = NetworkInterface.getNetworkInterfaces();

while (networkInterfaces.hasMoreElements()) {
  NetworkInterface networkInterface = networkInterfaces.nextElement();
  Enumeration<InetAddress> inetAddresses = networkInterface.getInetAddresses();

  while (inetAddresses.hasMoreElements()) {
    InetAddress inetAddress = inetAddresses.nextElement();

    byte[] address = inetAddress.getAddress();
  }
}

Note: This will return the private network IP Address. If you want the public IP Address you will need to use STUN (try jSTUN).

Hope that helps!
