Material DateTime Picker
Pick a date or time on Android in style
Material DateTime Picker tries to offer you the date and time pickers as shown in the Material Design spec, with an easy themable API. The library uses the code from the Android frameworks as a base and tweaked it to be as close as possible to Material Design example. (Android 4.0 was supported until 3.6.4). The easiest way to add the Material DateTime Picker library to your project is by adding it as a dependency to your build.gradle. You may also add the library as an Android Library to your project. All the library files live in library. The library also uses some Java 8 features, which Android Studio will need to transpile. The library follows the same API as other pickers in the Android framework. The library contains 2 layout versions for each picker. Version 1 is the original layout. It is based on the layout google used in the kitkat and early material design era. And version 2 is based on the guidelines google posted when launching android marshmallow. -

PiracyChecker
An Android library that prevents your app from being pirated
An Android library that prevents your app from being pirated / cracked using Google Play Licensing (LVL), APK signature protection and more. API 14+ required. This library applies some techniques to help protect your app's users and attempt to thwart reverse engineers and attackers. BUT, this isn't guaranteed to stop your app from getting pirated. There is no such thing as 100% security, and a determined and skilled attacker with enough time, could remove these checks from the code. The real objective here is to raise the bar out of reach of opportunist and automatic attackers. Google Play offers a licensing service that lets you enforce licensing policies for applications that you publish on Google Play. With Google Play Licensing, your application can query Google Play to obtain the licensing status for the current user. Any application that you publish through Google Play can use the Google Play Licensing service. No special account or registration is needed. -

We are actively working towards a re-release to the Play Store, and this app will be the spiritual successor to the original GitHub app. We're shooting for an initial re-release just to get the app out there. There have been a significant number of changes since the app was last updated, with many functional and design changes that we need to make sure are good to go. Much of the UI has already been touched up with elements of Material Design, but we have a long ways to go. Android has changed a lot since this was actively developed, and it's time we take advantage of those changes. -
