Have you ever thought on how much bandwidth have a feature phone? Why the software runs better on gingerbread? Sincerely I'm not satisfied with the performance I get on CPU neither because I can do better with other OS. Talking about CPU performance the software runs far better on Galaxy Note (Gingerbread 1280x800) than on Galaxy Nexus (ICS 1280x720).

You know that that was only an example, in real life drawLine can't be replaced with drawLines at least not always. > Again, the problem is that a GPU performs very differently from a CPU. > Batching rendering operations is one of the best optimizations you can > do when running on the GPU. > > > In any case on the android documentation (API Level 11) I finded that > > drawLines() doesn't support antialiasing: > >http://developer.android.com/guide/topics/graphics/hardware-accel.html > > why do you call this a bug? > > This documentation is out of date.

Are you really asking to drop Level 11 support or double the code to draw some lines? -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
