## Overview

GestureLockView is an Android gesture-pattern input library, accompanied by a small sample app. The main workflow is touch input on the configurable grid, pattern collection and minimum-length/password checks, then success or error callbacks; the sample validates a hard-coded pattern and opens a second screen on success. The excerpts show those callback and sample-screen links, but not all drawing and touch-handling details. The README documents configurable appearance, grid size, security mode, vibration, and listener behavior.

### Sample app

- [Sample screen](https://github.com/leondevlifelog/gesturelockview/blob/master/app/src/main/java/com/github/leondevlifelog/gesturelockviewsample/MainActivity.java): `app/src/main/java/com/github/leondevlifelog/gesturelockviewsample/MainActivity.java`
- [Result screen](https://github.com/leondevlifelog/gesturelockview/blob/master/app/src/main/java/com/github/leondevlifelog/gesturelockviewsample/SecondActivity.java): `app/src/main/java/com/github/leondevlifelog/gesturelockviewsample/SecondActivity.java`

### Other components

- **User**
- **Android vibrator**

- Gesture input → Sample screen: calls listener (evidence: `gesturelockview/src/main/java/com/github/leondevlifelog/gesturelockview/GestureLockView.java`)
- Sample screen → Gesture input: configures listener (evidence: `app/src/main/java/com/github/leondevlifelog/gesturelockviewsample/MainActivity.java`)
- Sample screen → Result screen: opens on success (evidence: `app/src/main/java/com/github/leondevlifelog/gesturelockviewsample/MainActivity.java`)
- Gesture input → Android vibrator: vibrates (evidence: `gesturelockview/src/main/java/com/github/leondevlifelog/gesturelockview/GestureLockView.java`)
