The view drawing cache was largely produced obsolete Using the introduction of hardware-accelerated rendering in API eleven. With components-acceleration, intermediate cache levels are mostly unwanted and can certainly bring about a net loss in effectiveness as a result of the expense of generating and updating the layer. Within the uncommon conditions where by caching layers are helpful, including for alpha animations, setLayerType(int, android.graphics.Paint) handles this with hardware rendering.

Application layers really should be avoided if the impacted view tree updates normally. Each and every update would require to re-render the computer software layer, which can perhaps be gradual (specifically when components acceleration is turned on Because the layer must be uploaded into get more info a hardware texture after every single update.)
