Grafika
Grafika test app
Welcome to Grafika, a dumping ground for Android graphics & media hacks. A collection of hacks exercising graphics features. An SDK app, developed for API 18 (Android 4.3). While some of the code may work with older versions of Android, some sporatic work is done to support them. Open source (Apache 2 license), copyright by Google. So you can use the code according to the terms of the license, A perpetual work-in-progress. It's updated whenever the need arises. To some extent, Grafika can be treated as a companion to the Android System-Level Graphics Architecture document. The doc explains the technology that the examples rely on, and uses some of Grafika's activities as examples. Features are added to Grafika as the need arises, often in response to developer complaints about correctness or performance problems in the platform. -

Creates small slices from your productive database and imports the data into your development and test environment (consistent and referentially intact). Improves database performance by removing and archiving obsolete data without violating integrity. The Data Browser lets you navigate through your database following the relationships (foreign key-based or user-defined) between tables. Generates SQL (topologically sorted), XML (hierarchically structured) and DbUnit datasets. A demo database is included with which you can get a first impression without any configuration effort. -

MaterialViewPager
A Material Design ViewPager easy to use library
The MaterialViewPager project is an Android library that simplifies building a “ViewPager + material-design header” interface: basically, you get a scrolling interface where pages are swipable and a header at the top — often with an image — that can animate (e.g. Ken Burns effect) or behave according to scroll, giving a polished “material-design + parallax / dynamic header” UI out of the box. It abstracts away the boilerplate associated with combining a ViewPager + PagerAdapter + header + toolbar + tabstrip — so instead of wiring all that manually, you drop in a single custom view in your layout and configure with XML attributes (header height, header image or logo, colors, fade, etc). The library supports customizing header appearance (static or animated), logos, toolbar behavior when you scroll, and integrates with Android’s view hierarchy (tabs, recycler views). -

MeGit
Standalone Git GUI based on EGit
Looking for a powerful, yet easy-to-use, fully open-source user interface for git? Well, there are plenty of options. One of our favorites is EGit. However, EGit is actually a plug-in for Eclipse rather than a standalone tool, such as GitKraken, etc. Nevertheless, even in projects where we actually use other editors or IDEs than Eclipse, we often found ourselves firing up an Eclipse IDE with EGit just to handle more complex git branch operations, for analysing the git history, and so on. This made us think, wouldn't EGit be a great git standalone tool if it would be... well, an actual standalone tool? That's exactly what MeGit is: a minimal standalone application that contains just enough to run EGit conveniently. Nice visualization of the git history making it easy to keep a good overview when analyzing, merging or rebasing branches, cherry-picking commits, changing the git history, etc. -

Official Android SDK for Stream Chat
Android Chat SDK ➜ Stream Chat API. UI component libraries for chat
This is the official Android SDK for Stream Chat, a service for building chat and messaging applications. This library includes both a low-level chat SDK and a set of reusable UI components. Most users start with the UI components and fall back to the lower-level API when they want to customize things. We're proud to say that we're the first Android Chat SDK that supports Jetpack Compose! We released our Compose UI Components one day after the official Jetpack Compose 1.0 release and our team members have been working hard on it since then. Now it's mature and stable enough for us to officially recommend it for all new applications and all modern chat implementations. If you're looking for something highly customizable and extremely performant, check out our Compose SDK. -

Phosphor (for Fabric)
A Fabric mod designed to improve the performance of Minecraft
Phosphor is a free and open-source Minecraft mod (under GNU GPLv3) aiming to save your CPU cycles and improve performance by optimizing one of Minecraft's most inefficient areas-- the lighting engine. It works on both the client and server and can be installed on servers without requiring clients to also have the mod. The mod is designed to be as minimal as possible in the changes it makes, and as such, does not modify the light model or interfaces of vanilla Minecraft. Because of this, Phosphor should be compatible with many Minecraft mods (so long as they do not make drastic changes to how the lighting engine works.) If you've ran into a compatibility problem, please open an issue. -

Piranha
A tool for refactoring code related to feature flag APIs
Feature flags are commonly used to enable gradual rollout or experiment with new features. In a few cases, even after the purpose of the flag is accomplished, the code pertaining to the feature flag is not removed. We refer to such flags as stale flags. The presence of code pertaining to stale flags can have the following drawbacks. Unnecessary code clutter increases the overall complexity w.r.t maintenance resulting in reduced developer productivity The flags can interfere with other experimental flags (e.g., due to nesting under a flag that is always false) Presence of unused code in the source as well as the binary. Stale flags can also cause bugs. Piranha is a tool to automatically refactor code related to stale flags. At a higher level, the input to the tool is the name of the flag and the expected behavior, after specifying a list of APIs related to flags in a properties file. -
