Open Source Java Compilers for Mobile Operating Systems

Some of Bytecode Viewer features are that it provides Java Decompiling with Six different decompilers (DJ-GUI/Core, Procyon, CFR, Fernflower, Krakatau, and JADX-Core). Bytecode Decompiling with CFIDE. Android APK integrated with Dex2Jar. Securely launch Java applications and insert hooks via EZ-Injection. Scan for malicious code with the Malicious Code Scanner plugin. Export as DEX, Jar, Class, Zip or Java Source File. Open Android APKs, Android DEX, Java Class Files and Java Jars. (WAR & JSP Support!). Extensively configurable, over 100+ settings! Works seamlessly with all Operating Systems. Integrates BCV into Windows by installing it, it'll associate all .class, .dex and .apk to open with BCV. You can view Jar & APK Resources with ease by APKTool.jar integration. It is 100% free and open sourced under GPL v3 CopyLeft.

A programming language AL-IV (ALFOUR) is a high-level imperative object oriented programming language with minimal introduction level, easy porting to any platform claiming a very high level of safety and stability, with a controllable level of code protection, high efficiency of an executable code, full independence from a target platform, minimal enter level.

Jump is a software development tool for Java on the PalmOS platform. It compiles Java classfiles to self-contained 68K assembly language programs for Pila.

An android client of CodePad.org & ideone.com CodePad.org is an oneline free multi-language compiler for developers. ideone provide non-free services for the same work. ideone is much more powerful Now the tool support C,C++,Java (for ideone), Bash (for ideone), R (for ideone), Python, Ruby, Perl, PHP

C-Lesh is a game programming language for 2D games - mainly arcade and platform games. When combined with the Super Mario World (SMW) engine you can create awesome 2D platform games like Super Mario World. This language evolved from a "clone" of TI-BASIC which I began developing when I was having memory (segmentation fault) bugs with C. C-Lesh lacks memory allocation and destruction. There is no need to use pointers and you can never get memory leaks or program crashes caused by memory leaks. As C-Lesh is somewhat primitive you may like it if you are into C. I'd say its a step up from C for 2D games. Everything is set - all you need is a sprite sheet and some programming knowledge.

Forth compiler for the Compiled Virtual Machine

The EMP language (Easy Mobile Programming) is an easy-to-use programming language for developing independent Symbian OS applications. The primary goal is to provide an easier alternative for the Symbian OS C++.

JNC means java native compiler. It take the java byte code file as input and translate it to C or ASM format then compile to native format such as elf or pe file. So your java program can run without JVM.

Jaune is a compiler and set of libraries that can be used to write programs in the Java language for small devices. Includes a basic set of class libraries, garbage collector, and set of examples that can be run on the Nintendo GameBoy

LucidEngine is a simple layer over MIDP compatible phones that will let you write simple and old fashioned games using a specific language. Every game you'll develop will basically work on all the devices (even not phones) LucidEngine as been ported.

The purpose of this project is to modify SmartEiffel to allow it to be used to create applications for mobile device platforms such as Symbian, BREW, and J2ME. Currently the codebase is based on SmartEiffel 1.0, but we are looking into moving over to Sma

RockScript is the world's smallest Java-based JavaScript interpreter, runs smoothly in any J2ME phones. The binary size of core engine including native objects/methods is less than 25K (obfuscated & JAR'ed). It can be integrated into any J2ME apps.

OS based on Agent based Security with a new type of split kernel and agents platform.

dxcut is a library for reading, editing, and writing dex and odex files which contain the class definition and Dalvik bytecode used by the Android operating system. This project includes a disassembler/decompiler, dex optimizer, and hooking utils.

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.
