I have some class for ssh support - it uses jsch internally. I use this class on main activity, this way:

public class MainActivity extends Activity
{

 SshSupport ssh = new SshSupport();

.....

 @Override
    protected void onCreate(Bundle savedInstanceState)
    {
        super.onCreate(savedInstanceState);



    //Handle events for ssh
    ssh.eventHandler = new ISshEvents()
    {


        @Override
        public void SshCommandExecuted(SshCommandsEnum commandType, String result)
        {

        }

      //other overrides here


    }

        //Ssh operations on gui item click 
        @Override
        public void onItemClick(AdapterView<?> arg0, View v, int position, long arg3)
        {

            if (ssh.IsConnected() == false)
            {
                try
                {

                    ssh.ConnectAsync(/*parameters*/);

                }
                catch (Exception e)
                {
                    e.printStackTrace();
                }
            }

            try
            {
                ssh.ExecuteCommandAsync(SshCommandsEnum.values()[position]);
            }
            catch (Exception e)
            {
                e.printStackTrace();
            }

        }
    });

}

It works very well. My application connects to ssh, performs all needed operation in background thread and results are reported to gui, via events as shown above. But nothing works after user change device orientation. It's clear for me - activity is re-created and all state is lost. Unfortunately, my SshSupport class object is lost as well.

It's pretty easy to store gui state for dynamically changed/added objects (using put/get serializable etc methods). But I have no idea how to prevent my ssh object, ssh connected session being lost.

Since my class is not serializable, I can't save it to bundle. Also, even if I make my SshSupport class serializable, jsch objects it uses still are not serializable.

So what is the best way to solve this?
