Today I found a short description on wikipedia about how many technologies are in mobile application development area.
http://en.wikipedia.org/wiki/Mobile_application_development You can choose your programming language that you prefer to use, and you will find which mobile platform you can address with it.
The Codename One technology uses the java language and enables Java Developers to build true native applications for all mobile/tablet platforms. Sounds quite interesting and it is. However, for the J2ME enabled phones, personally I prefer to use the j2me language and environment with the Netbeans IDE.
Codename One declares that you have just 5 easy steps for app development:
- downloading the codename one plugin for free (eclipse or netbeans)
- write your code in java
- you have a designer for the GUI
- and you have an embedded simulator to test your app
- Generate a native mobile application for the desired device, sending to the build server, your code to be build. (you can do this from your IDE)
