rendering stay organized with collections save and categorize content based on your preferences ui rendering is the act of generating a frame from your app and displaying it on the screen to help ensure that a user s interaction with your app is smooth your app must render frames in under 16ms to achieve 60 frames per second fps if your app suffers from slow ui rendering then the system is forced to skip frames and the user perceives stuttering in your app this is called jank note for information on how to diagnose and resolve this issue see slow rendering android vitals metrics to help improve app quality android automatically monitors your app for jank and frozen frames and displays the information in the android vitals dashboard for information about how the data is collected see monitor your app s technical quality with android vitals slow frames ui frames that take longer than 16ms to render frozen frames ui frames that take longer than 700ms to render this is a problem because your app appears to be stuck and is unresponsive to user input for almost a full second while the frame is rendering during app startup or while transitioning to a different screen it s normal for the initial frame to take longer than 16ms to draw because your app must inflate views lay out the screen and perform the initial draw all from scratch that s why android tracks frozen frames separately from slow rendering no frames in your app should ever take longer than 700ms to render note the android vitals dashboard and android system keep track of render time and frozen frame statistics for apps that use the view based ui toolkit where the user visible portion of the app is drawn from canvas or the view hierarchy if your app doesn t use the view based ui toolkit as is the case for apps that are built with vulkan unity unreal or opengl then render time and frozen frame statistics aren t available in the android vitals dashboard to determine if your device is logging
