Android Activities have a lifecycle and do not use a main() function.

If you want to start and stop the webserver as part of the Activity then you need call start and stop in onPause and onResume, ie

public class MyActivity extends Activity {

    private MyHTTPD mServer;

    @Override
    protected void onResume() {
        super.onResume();

       try {
            mServer = new MyHTTPD();
            mServer.start();
        } catch (IOException e) {
            e.printStackTrace();
            mServer = null;
        }


    @Override
    protected void onPause() {
        super.onPause();
        if(mServer != null) {
            mServer.stop();
            mServer = null;
        }
    }
}

An alternative is to implement the webserver as part of a Service.

In an app I'm working I have a requirement to keep the webserver running even if the user leaves the app. The only way to do this is to start and stop the webserver as part of a long-running Service that is not bound to the Activity. See Vogella's great tutorial on Android Services.
