Class RenderingMetrics

  • 
public final class RenderingMetrics

    Class aggregating raw frame metrics into more high level representation suitable for reporting and simpler to analyze

    • Constructor Detail

      • RenderingMetrics

        RenderingMetrics(Long totalFrames, Long slowFrames, Long frozenFrames, Long droppedFrames, Long totalFreezeTimeMs, Long foregroundTimeMs)

    • Method Detail

      • getTotalFrames

         final Long getTotalFrames()

        Total amount of frames rendered during the screen session

      • getSlowFrames

         final Long getSlowFrames()

        Amount of frames that take more that 16ms to render (considered as "slow")

      • getFrozenFrames

         final Long getFrozenFrames()

        Amount of frames that take more that 700ms to render (considered as "frozen")

      • getDroppedFrames

         final Long getDroppedFrames()

        Amount of "good" frames that potentially could be rendered, but were "dropped" due to rendering performance issues.

        For instance if we target 60fps, the "good" frame would be any frame rendered for less than 16ms. But when we see "slow" frame that take 48ms to render, it spend the same time to render as 3 "good" frames would spend. That means that due to performance issue the app has rendered 1 frame, but 2 potentially good frames were dropped

      • getTotalFreezeTimeMs

         final Long getTotalFreezeTimeMs()

        Total time of freezing the UI due to rendering of the slow frames per screen session. This metric accumulates all freeze durations during the screen session

      • getForegroundTimeMs

         final Long getForegroundTimeMs()

        Total time spent by user on current screen. Helpful as a supporting metrics, since sometimes increase in Total Freeze Time might be caused by longer interactions with the screen
