I've been thinking about this, why would you use java on a phone? Sure it's easy to program and communication is simple but it makes little sense for mobile 200 Hz processors. The java language requires a virtual machine, that takes up resources like a mad man. Even Java on the PC (Think Processing and such) requires a ton of system resources to operate smoothly. C++ perform flawlessly no matter what. I'm just curious as to why use Java and reduce performance when you can develop apps in C++ faster and also be assured that your app will run smooth under any condition. Also the majority of cell phones use ARM processors anyway so C is the language of choice.
