Tested in Facebook. The portal needed to be multi tenant and support branding and configuration for different Retailers. Developers can use the Profile HWUI rendering option in testing. The Profile GPU Rendering tool indicates the relative time that each stage of the rendering pipeline takes to render the previous frame. See the trick below for how to paste CSV data into columns. the next task. The sections of the colored bars can indicate where in your app you might look for performance problems. We all enjoy smooth applications, and view rendering depends on how efficient your structure is. transfers the bitmap to GPU memory before the GPU can render it to the As a refresher, watch the Invalidation, Layouts, and Performance video for an overview of the Android rendering pipeline.
