Android Intents, how to pass and receive an InetAddress?

I have the following line of code

intent.putExtra("connectionAddress", connectionManager.connectionAddress);

connectionAddress is in fact an InetAddress. I cannot figure out the appropriate method to 'get..' this. I suspect I need to cast it to another type and back again? In which case what would be the best approach?

I need to ensure I still have the information needed to create a DatagramSocket in the next activity.

Solution

  • You need to get the address from the intent as a serializable extra, then cast it back to InetAddress.

    InetAddress address = (InetAddress)intent.getSerializableExtra("connectionAddress");
