I have made a racing game, and need update the dash board frequently, e.g: the current speed of player, the current ranking of player, the current score of player, the current time of race and so on.
I use Android-GUI for this now, it works fine for static views, but slowly for views which update frequently. After measuring, the updating of GUI was one of the bottlenecks. I have controlled the rate of updating, but the performance was also not good enough.
