Open Source Java Design Software

GmsCore fork designed for ReVanced with Material You design, along with some improvements and features.

A comprehensive, community-maintained collection of design pattern implementations in Java, offering well-documented, educational examples to help developers understand and apply common architectural solutions. All designs should be as simple as possible. You should start with KISS, YAGNI, and Do The Simplest Thing That Could Possibly Work principles. Complexity and patterns should only be introduced when they are needed for practical extensibility. The design patterns are now available as an e-book. Design patterns can speed up the development process by providing tested, proven development paradigms.

The Android Image Slider project is an Android UI component/library that provides a convenient, customizable image slider (carousel) for mobile apps. Instead of building a custom slider from scratch, developers can drop in this library’s slider view into their layout and configure it via XML or code to display a series of images — from local drawables, files, or remote URLs — with smooth transitions, animations, and optional indicators. This significantly simplifies development of galleries, onboarding screens, advertisement banners, or any UI requiring swipable images in Android apps. The library supports various slide animations (transitions), auto-sliding, and event listeners (e.g., click events on slides), giving developers flexibility around how the slider behaves. For mobile apps where image-heavy UI is common (e.g. e-commerce, portfolios, media galleries), AndroidImageSlider offers a ready-made, tested component that saves time and ensures consistency.

Lottie is a wonderful library for Android, iOS, Web, and Windows that works by parsing Adobe After Effects animations that have been exported as json with Bodymovin, and then rendering these natively on mobile and on the web! Now you can have beautiful animations without engineers having to recreate everything by hand. Building animations by hand is time consuming, and other animation alternatives like Gifs and Png sequences don’t offer the same flexibility and varied features that Lottie offers. With Lottie, you can achieve exquisite animations exactly how you want, with no additional engineering effort whatsoever. Take a look at the many beautiful animation possibilities available to you on http://airbnb.io/lottie/

Shimmer is an Android library that provides an easy way to add a shimmer effect to any view in your Android app. It is useful as an unobtrusive loading indicator that was originally developed for Facebook Home. Shimmer for Android is implemented as a layout, which means that you can simply nest any view inside a ShimmerFrameLayout tag, and call to start the animation from your code. That's all that is required. The layout will use the values you specify either on the tag (using custom attributes) or programmatically in your code, and generate an animation on the fly. See the API reference for further details. Note that you cannot use the custom attributes on the tag if you use the Jar file. You can instead download the AAR file and reference that locally in your project. You can use the included Gradle wrapper to build the Shimmer library and sample application locally as well.

Structorizer is a little tool which you can use to create Nassi-Schneiderman Diagrams (NSD). Stuctorizer is written in Java and free for any use. The code has been moved to Github: https://github.com/fesch/Structorizer.Desktop

Application simplifies the development and management of VHDL projects. The project is displayed in a well-arranged tree structure depending on the hierarchy of entities. It also helps to maintain projects in a consistent state. Other features include automatic generation of VHDL testbenches and structures based on user-defined templates. The NetBeans platform is used as a basis for the implementation.

BIRT is an open source technology platform used to create data visualizations and reports that can be embedded into rich client and web applications. Developers who use BIRT Designer are able to access information from multiple data sources easily and quickly in order to create reports and applications with stunning data visualizations. Actuate now provides a free report server, BIRT iHub F-Type, to deploy BIRT content so developers don't have to build their own infrastructure. With a flexible Open Data Access framework, developers can write custom data drivers to access data from any source, including Big Data sources like Apache Hadoop, Cassandra, and MongoDB, along with all traditional relational databases, Flat Files, XML data streams, and data stored in proprietary systems. Built for embedding, BIRT includes APIs for data access, chart generation, output formats, content execution, and integration within larger applications.

ConceptBase.cc is a multi-user deductive and object-oriented database system for metamodeling and method engineering. Includes a graphical client that builds upon the logic-based features of the ConceptBase.cc server. The data model is O-Telos. ConceptBase.cc can represent information at the data level (example data, traces of process executions etc.), the class level (schemas, process definitions etc.), the metaclass level (constructs of modeling languages), the meta-metaclass level (constructs for defining modeling languages), and so forth. ConceptBase.cc is developed by the ConceptBase Team at University of Skövde (HIS). ConceptBase.cc supports Linux, Mac OS X and Windows. ConceptBase.cc is free software distributed under a FreeBSD-style license.
