Why doesn't Android's GUI use GPU acceleration?
The biggest turnoff I have had with Android is how choppy elements of the graphical user interface are. It really affects the snappiness of the device. These are things like the animation of pulling the app drawer out, or scrolling through a page. Even on the Droid scrolling through a webpage is choppy, laggy and slow.
What I do know is that the iPhone takes advantage of the GPU and OpenGL to accelerate all these things. That is why all the animations and scrolling on the iPhone are silky smooth. What has always puzzled me is why they built Android to not take advantage of hardware that are in most of its phones. The CPU can only do so much, so it makes sense to have the GPU do what it's best at.
I read something once about Skia, the 2D rendering engine for Android, only being able to use the CPU. But how far off, if ever, are we from seeing GPU integration into the actual GUI? I'm not talking about games, I am talking the OS itself.
