Open Source Android Interface Engines

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.

Designed for data-logging applications (weather, hydroponics, greenhouses, aquariums, home automation, power consumpion, solar or wind generators etc.), this solution can be useful also in alarms and burglar. Now you can develop MySQL and web enabled Arduino applications only working on Arduino and PHP. To keep ligth the Arduino Sketch, you can port all not realtime logic to PHP side. At the end your application will works on XQ+Arduino UNO even 24/7 with only 20 Watt AC power, and can be controlled by smartphone via WiFi or from Internet using some free dynamic IP. What more? Enjoy.
