## Overview

This repository is a collection of Android learning notes and reference material, not an executable application. The principal workflow is for a learner to start at the root index and open a topic-specific guide or quick reference. The graph preserves the major documented branches and groups related material by subject; the source excerpts show a custom-view example, but not runtime connections between the documents. Links shown are those explicitly listed in the root README.

Main entry points: [`README.md`](https://github.com/gcssloop/androidnote/blob/master/README.md) (Topic Index), [`CustomView/Base/[01]CoordinateSystem.md`](https://github.com/gcssloop/androidnote/blob/master/CustomView/Base/%5B01%5DCoordinateSystem.md) (View Basics), [`CustomView/Advance/[02]Canvas_BasicGraphics.md`](https://github.com/gcssloop/androidnote/blob/master/CustomView/Advance/%5B02%5DCanvas_BasicGraphics.md) (Drawing Topics), [`CustomView/Advance/[12]Dispatch-TouchEvent-Theory.md`](https://github.com/gcssloop/androidnote/blob/master/CustomView/Advance/%5B12%5DDispatch-TouchEvent-Theory.md) (Touch Topics)
