Yesterday, I did Career Guidance in ICT that Organized by Sri Lanka Foundation Institute. I did session ‘Developing Simple Mobile Applications’.

I briefed about Mobile application development

“Mobile application development is the process by which applications are developed for small low-power handheld devices such as personal digital assistants, enterprise digital assistants or mobile phones. These applications are either pre-installed on phones during manufacture, or downloaded by customers from app stores and other mobile software distribution platforms.”

This was the path for the session on that day

• › J2me Hello world (Demo)
