Hacker Scripts
Based on a true story
Hacker Scripts is a cheeky collection of small automation scripts and language ports collected under the tagline “Based on a true story.” The repository gathers playful utilities (originally shell and Ruby scripts) that automate short, real-world tasks — for example, sending a quick “late at work” text when SSH sessions are active, firing off an automated “I’m sick / working from home” email on certain mornings, or even talking to a networked coffee machine to start brewing at precisely the right moment. The README explains the origin story and highlights several canonical scripts and provides usage notes such as required environment variables and cron examples for scheduling. Contributors have provided implementations and ports in many languages and folders (shell, Ruby, Python, Node, Perl, PowerShell, Go, Java, etc.), and the project explicitly welcomes pull requests that add additional language implementations. -

LeakCanary
A memory leak detection library for Android
LeakCanary is a reliable memory leak detection library for Android. It effectively detects leaks and narrows down the cause of each leak through its in-depth knowledge of the internals of the Android Framework. This helps developers avoid and dramatically reduce OutOfMemoryError (OOM) crashes. A memory leak is a programming error that can cause an OutOfMemoryError crash. It’s often caused by bugs related to the lifecycle of objects, and can occur fairly often in Android applications. LeakCanary helps to find and fix those leaks during development so you never have to experience another OOM crash. -

Image Picker Library for Android
Image Picker for Android, Pick an image from Gallery
Easy to use and configurable library to Pick an image from the Gallery or Capture an image using a Camera. It also allows to Crop and Compress the Image based on Aspect Ratio, Resolution, and Image Size. Almost 90% of the apps that I have developed have an Image upload feature. Along with the image selection, Sometimes I needed a crop feature for my profile image for that I've used uCrop. Most of the time I need to compress the image as the image captured from the camera is more than 5-10 MBs and sometimes we have a requirement to upload images with specific resolution/size, in that case, image compression is the way to go option. To simplify the image pick/capture option I have created the ImagePicker library. I hope it will be useful to all. -

Anko
An Android application development library
Anko is a Kotlin library which makes Android application development faster and easier. It makes your code clean and easy to read, and lets you forget about rough edges of the Android SDK for Java. Anko was born as a type-safe DSL for building Android layouts. It not only allowed creating layouts in a type-safe way, but it made the layouts more adaptable, dynamic, reusable, and also performant, as there was no need for expensive layout inflation. Anko consists of several parts that make up the complete framework, which are: Anko Commons: a lightweight library full of helpers for intents, dialogs, logging and so on. Anko Layouts: a fast and type-safe way to write dynamic Android layouts. Anko SQLite: a query DSL and parser collection for Android SQLite. Anko Coroutines: utilities based on the kotlinx.coroutines library. -

Android Developer Roadmap
The Android Developer Roadmap offers comprehensive learning paths
Android Developer Roadmap suggests learning paths to understanding Android development. The Android Developer Roadmap is designed to give you a comprehensive understanding of the current Android ecosystem and provides suggested learning paths along the way to help you grasp the concepts. Each node indicates concepts of Android systems, Android SDK, and generally used libraries. It would be helpful to refer to the Android Developers Reference or GitHub for the specific terminologies. In addition, you don't need to learn everything from this roadmap. So we recommend only reading the sections that would be helpful to you. -

GraphQL Java Tools
A schema-first tool for graphql-java inspired by graphql-tools for JS
This library allows you to use the GraphQL schema language to build your graphql-java schema. Inspired by graphql-tools, it parses the given GraphQL schema and allows you to BYOO (bring your own object) to fill in the implementations. GraphQL Java Tools works extremely well if you already have domain POJOs that hold your data (e.g. for RPC, ORM, REST, etc) by allowing you to map these magically to GraphQL objects. GraphQL Java Tools aims for seamless integration with Java, but works for any JVM language. Try it with Kotlin. -

KMP NativeCoroutines
Library to use Kotlin Coroutines from Swift code in KMP apps
A library to use Kotlin Coroutines from Swift code in KMP apps. Both KMP and Kotlin Coroutines are amazing, but together they have some limitations. The most important limitation is cancellation support. Kotlin suspend functions are exposed to Swift as functions with a completion handler. This allows you to easily use them from your Swift code, but it doesn't support cancellation. Besides cancellation support, ObjC doesn't support generics on protocols. The library consists of a Kotlin and Swift part which you'll need to add to your project. -

kotlinx.coroutines
Library support for Kotlin coroutines
Library support for Kotlin coroutines with multiplatform support. Kotlin, as a language, provides only minimal low-level APIs in its standard library to enable various other libraries to utilize coroutines. Unlike many other languages with similar capabilities, async and await are not keywords in Kotlin and are not even part of its standard library. Moreover, Kotlin's concept of suspending function provides a safer and less error-prone abstraction for asynchronous operations than futures and promises. kotlinx.coroutines is a rich library for coroutines developed by JetBrains. It contains a number of high-level coroutine-enabled primitives that this guide covers, including launch, async and others. Coroutines can be thought of as light-weight threads, but there is a number of important differences that make their real-life usage very different from threads. -
