Android 4.0 有很多新功能和改動,其中一項就是有關硬體加速(Hardware Acceleration)。
在 Android 3.0 推出時,已經在平板支援硬體加速。而在 Android 4.0會有進一步的改進。
With this new pipeline, all drawing operations performed by the UI toolkit are carried out using the GPU.
You’ll be happy to hear that Android 4.0, Ice Cream Sandwich, brings an improved version of the hardware-accelerated 2D rendering pipeline to phones, starting with Galaxy Nexus.
操作界面更流暢
在Android 4.0 以前,在 App 內要使用硬體加速,都要開發者在 App 內主動設定。而 Android 4.0 (API level 14) 都會預設開啟硬體加速。
In Android 4.0 (API level 14), hardware acceleration, for the first time, is on by default for all applications.
即是,所有以 Android 4.0 (API Level 14)開發的 Apps 都可以透過硬體加速提升表現,操作界面會更加流暢。
