The table below gives an explanation. The Android system issues draw commands to the GPU, and then moves on to its next task. Several users are enabling it on their phone for: Not everyone owns the latest flagship. specific data that describes the size of the object on the screen. The above may contain affiliate links. Some views The Profile GPU Rendering tool gives you a quick visual representation of how much time it takes to render the frames of a UI window relative to the 16-ms-per-frame benchmark. Now you may forget to turn this option off. scrolling can appear in this phase. To mitigate this problem, reduce the complexity of work occurring on the GPU, similar to what you would do for the "Command issue" phase. Once you understand what each color signfiies, For example, when you first load an image, the bar may go above the green line, but users may not notice a problem, because they may expect to wait a moment for an image to load. The Profile GPU Rendering tool indicates the relative time that each stage of the rendering pipeline takes to render the previous frame. And the good thing is you dont even have to install anything!

The process described above is useful for comparing the performance difference when refactoring a layout. With those spec, when I open "Snapdragon Profiler", after succesfully connected the device, I can only see realtime spec for CPU, memory, etc, but NO GPU realtime stats. We all enjoy smooth applications, and view rendering depends on how efficient your structure is. Sometimes the slowness is due to the view not being programmed properly and doing something called overdraw. Simple views where you're not scrolling or doing any animations is one example of this. Some of them will stay in memory for a while. If there are issues, tools are available to help diagnose slow rendering. The bars for older versions use different coloring.
