AND103 - Android "Internet" Network Programming (4 days)

Course Outline

This course concentrates on the internet programming aspects of developing Android mobile applications.

Topics covered include working with the HttpClient, external JARs, local and remote services as well as integrating media players and web based resources into applications. Notifications, location tracking and Google maps are also covered.

Course Objectives

The goals of this course are to explore the "networking" aspects of Android application development in greater depth than could be covered in a more general Android programming course.


The course assumes that attendees are already familiar with HTML, Javascript and Java programming as well as basic Android application development techniques.
