The Care and Feeding of the Android GPU

bonch writes "Charles Ying argues that Android's UX architecture has serious technical issues because, unlike the iPhone and Windows 7, Android composites the interface in software to retain compatibility with lower-class devices. Additionally, Android runs Java bytecode during animation, and garbage collection blocks the drawing system. Google engineers dismiss the desire for hardware-accelerated compositing and cite more powerful hardware and an avoidance of temporary objects as a solution to the collection pauses, but Ying argues that will just lead to [a lower] average battery life compared to devices like the iPhone."
