It means were using the right amount of code needed to draw this page. Most of the time, you probably want to compare the values before and after a change to your layout. The colored sections visualize the stages and their relative times. The level of difficulty depend on your personal experience. To demonstrate how doing too much work on the UI thread slows down your app, slow down drawing by putting the app to sleep: If your app is only swapping backgrounds, the impact from this change may not be significant for the user. For the draw pass, subtract the value under DrawStart from the value under SyncQueued. Ut elit tellus, luctus nec ullamcorper mattis, pulvinar dapibus leo. This developer option allowed you to force HWUI to use Skia and its hardware-accelerated OpenGL backend as the GPU renderer for the UI framework.

What's the difference between a power rail and a signal line? For example, having many draw operations, especially in cases where The colors in each bar represent the different stages in rendering the frame. As a refresher, watch the Invalidation, Layouts, and Performance video for an overview of the Android rendering pipeline. To get the time for the measure and layout pass, take the value under the PerformTraversalsStart column and subtract it from the value under the DrawStart column. Some views Profiling tools like Traceview or These are the nanosecond timestamps for each of the phases in the rendering of a frame (up to the last 120 frames). The feedback from customers has been overwhelmingly positive. What it does is it shows how much time does it take to render each frame compared to a benchmark of 16ms per second . .
