Open Source Java Software Development Software for Mobile Operating Systems

Symja - computer algebra language and Java symbolic math library. Moved to https://github.com/axkr/symja_android_library. The Android App can be found at: https://github.com/axkr/symja-example

ImageJ is a public domain Java image processing program inspired by NIH Image for the Macintosh. It runs, either as an online applet or as a downloadable application, on any computer with a Java 1.1 or later. HOME @ http://rsb.info.nih.gov/ij/

Android Auto Tester utilizes Android's monkey runner and hierarchy viewer to automatically traverses the hierarchy of an Android application's GUI and simulates user inputs from the host side, without accessing the application's source code.

Java library for parsing and evaluating math expressions. Javadoc is available at http://bracer.sourceforge.net/javadoc/ P.S. This library depends on Apache Commons Math, so don't forget to include commons-math-2.2.jar to your project.

CodeWhisk is an input method for Android that is designed to make programming code entry efficient (and fun!)

The Environment State Virtual Sensors for Android is a library that allows recognition of environmental scenarios in which an Android device can be found. The basic scenarios types are: Motion states, Noise states, Proximity state, ringer-mode state.

Create a sun, spin some asteroids around it, and watch them collide and form planets. An N-Point Gravity Simulator is a realistic simulation in which all points attract each other: even the smallest asteroid has its own gravitational field that can affect even a large sun far away from it. Can be reused as a library for making games. If used as library, license is GNU LGPLv3, otherwise it's GNU GPLv3.

J2ObjC is an open-source command-line tool from Google that translates Java source code to Objective-C for the iOS (iPhone/iPad) platform. This tool enables Java source to be part of an iOS application's build, as no editing of the generated files is necessary. The goal is to write an app's non-UI code (such as application logic and data models) in Java, which is then shared by web apps (using GWT), Android apps, and iOS apps. J2ObjC supports most Java language and runtime features required by client-side application developers, including exceptions, inner and anonymous classes, generic types, threads and reflection. JUnit test translation and execution is also supported. J2ObjC cannot convert Android binary applications. Developers must have source code for their Android app, which they either own or are licensed to use.

The Java Context Directory (JCD) is an information system to store and use contextual information. It enables a software developer to create context-aware applications and provides a client for mobile devices.

A lambda calculus interpreter for android.

Scalable Language API (SLAPI) The most comprehensive architecture for conversational natural-language applications including speech recognition/synthesis, semantics, & machine translation. Used on Android & other mobile app platforms.

Universal Tag Finder is a tool to query against html content in the file system. For developers it allows to find out relevant elements during the troubleshooting and validating periods. Does not need to bother on massive regex to find out elements.

Technological demo of OpenGL ES 2 for Android platform. It reads public NORAD satellite database and shows the satellite positions and altitude related to Earth in the form of beams (the height of the beam represents the relative altitude). NOTE: The project has been moved to GitHub: https://github.com/nuald/glSatellite-Demo The old one stays here just for the historical reasons. The 3D features present: - OpenGL ES 2; - rotating, multi-touch zooming and moving the globe; - stars on a fixed background; - each satellite is represented by a beam with a unique color; - identifying the corresponding satellite if a beam has been tapped (based on color picking method). Additionally to 3D features presented the application is: - using NDK with C++11 features compiled by LLVM clang; - mixing Java views with OpenGL views (Java is used for settings activity, information and ads panels); - using Android custom message queue to send asynchronous messages from Java to JNI

Cross-platform data acquisition and visualization software with an embedded HTTP-server, binary protocol parsing library, protocol emulation server, remote secure administration server, embedded Groovy scripting facilities and HMI (SCADA) visualization module.

A compiler to improve relation management between mobile users. This compiler will handle data islands for data transportation between a client mobile phone and a server node accesing a cellular network.
