 ConstraintLayout performance comparison
-===============================
+=======================================
 
-This app is an example test set that compares how the different ViewGroups
-(ConstraintLayout vs traditional layouts) affects the UI performance.
+This repo has been migrated to [github.com/android/performance-samples][1]. Please check that repo for future updates. Thank you!
 
-Introduction
-------------
-
-This app runs the measure/layout passes with the layout using
-ConstraintLayout and using traditional layouts (RelativeLayout and LinearLayout),
-both of them result in the same appearance but how the UI components are built is 
-different.
-
-![LayoutCodelab-UI](/art/layout-codelab.png)
-
-While running the measure/layout passes, the performance of UI is measured 
-by using [Systrace](https://developer.android.com/studio/profile/systrace-commandline.html) and 
-[OnFrameMetricsAvailableListener](https://developer.android.com/reference/android/view/Window.OnFrameMetricsAvailableListener.html)
-
-Pre-requisites
---------------
-
-You need to know:
-- Review the XML file to know how each layout is built
-  - [Layout using ConstraintLayout](/app/src/main/res/layout/activity_constraintlayout.xml)
-  - [Layout using traditional layouts](/app/src/main/res/layout/activity_traditional.xml)
-
-How to run the tests
----------------
-
-1. Download the code.
-2. Open the terminal at the downloaded directory.
-3. Run the following shell script `./run.sh <device_id>`
-  - The script is going to generate two html files as a result of running Systrace.
-    Each represents the performance result for the layout with ConstraintLayout and with
-    traditional.
-
-(Optional)
-- The app also logs the measurement result using OnFrameMetricsAvailableListener, but it isn't
-  exported to any external files. You can check those stats as well.
-
-Measurement result example
----------------
-Here is the example measurement result.
-
-![Comparison example](/art/constraint-performance-comparison-example.png)
-unit: ms, Time taken in measure and layout phases average of 100 frames
