# android-lockpattern



- Version: [`12.0.0`](version-info.md) _(December 23rd, 2016)_

    + _Starting from `8.0.0`, the library uses [Semantic Versioning 2.0.0]_

- License: [Apache License v2.0](LICENSE)

- Project page: 

- Demo: 

- For developers: [Wiki], [API documentation].



---



## Features



- Requires: Android 2.1+ (API 7+)

- Supported IDE: Android Studio

- _No run-time dependencies_

- _Designed with developers in mind._ You can pick up a stranger and weird library like this one, then use it right away without worrying about

  it invading your own [preferences][SharedPreferences], or breaking your app's resource names (or other libraries' resource names). Short

  answer: it uses a UUID for its preference file name, and a CRC-32 string to prefix its resource names (see [FAQs]).

- Designed for both _phones and tablets_

- Stealth mode (invisible pattern)

- Many built-in themes:

    + Dark/Light

    + Light with dark action bar (available from API 7+, but only works from API 14+)

    + Dark/Light dialogs

    + Dark/Light `DialogWhenLarge` (available from API 7+, but only works from API 11+)

- Ability to generate and let the user verify CAPTCHA pattern



In short, you can use this library in your closed source/commercial apps with or without our knowledge. Hope you enjoy it  `:-)`
