  },
  "fullyDrawnTime": {
    object (Duration)
  }
}
Fields
initialDisplayTime

object (Duration)

The time from app start to the first displayed activity being drawn, as reported in Logcat. See https://developer.android.com/topic/performance/launch-time.html#time-initial
fullyDrawnTime

object (Duration)

Optional. The time from app start to reaching the developer-reported "fully drawn" time. This is only stored if the app includes a call to Activity.reportFullyDrawn(). See https://developer.android.com/topic/performance/launch-time.html#time-full

GraphicsStats

Graphics statistics for the App. The information is collected from 'adb shell dumpsys graphicsstats'. For more info see: https://developer.android.com/training/testing/performance.html Statistics will only be present for API 23+.
