This directory contains a simple Android app that is meant to help in doing

controlled startup performance experiments.



This app is structured as a number of activities that each are useful for a

different aspect of startup testing.



# Activities



## EmptyActivity



This is the simplest possible Android activity. Starting this exercises only the

system parts of startup without any app-specific behavior.



    adb shell am start -n com.android.startop.test/.EmptyActivity



## LayoutInflation



This activity inflates a reasonably complex layout to see the impact of layout

inflation. The layout is supported by the viewcompiler, so this can be used for

testing precompiled layout performance.



The activity adds an `inflate#activity_main` slice to atrace around the time

spent in view inflation to make it easier to focus on the time spent in view

inflation.



    adb shell am start -n com.android.startop.test/.LayoutInflation
