Optimize and debug Android app

EUROPE-BASED, PLEASE!

We have an app running a Java communication layer with networked hardware, a Java web socket server, a Java HTML server, and a HTML browser with HTML / Javascript pages, all bundled into one app. This works, but it needs thorough testing and many little things need fixing. Once that is done, if we are happy with the cooperation, further functional things need to be added, and the app needs to be ported to iOS, Windows and OSX. This project is about getting the Android app finished ONLY, everything else will follow in later projects after this is ifnished.

Skills: Android, Java, Javascript, Mobile App Development, Software Architecture
