As a workaround you could launch your android device browser from a Processing app then enter your username and password when prompted. It takes very little code and does work.
import android.content.Intent;
import android.net.Uri;
void setup() {
fullScreen();
Intent intent = new Intent(Intent.ACTION_VIEW).setData(Uri.parse("http://xxx.xxx.xxx.xxx:yyyyy/stw-cgi/video.cgi?msubmenu=stream&action=view&Profile=10"));
startActivity(intent);
}
