+CanvasExample - Solution code
+=============================
+
+Draw on your device screen using your finger.
+
+Introduction
+------------
+
+This app uses a custom view to implement drawing on a canvas in response
+to touch events. All drawing happens on the UI thread by overriding the
+custom view's onDraw() method. You can use this technique when drawing
+always takes less time than a screen refresh cycle on all target devices.
+
+Pre-requisites
+--------------
+
+You need to know:
+- How to open, build, and run apps with Android Studio.
+- How to extract string resources and use string resources in the code.
+- How to create a custom view that handles touch or click events.
+- Basic understanding of the activity lifecycle.
+
+Getting Started
+---------------
+
+1. Download and run the app.
