Potential Android programmers face a very steep learning curve. Not only is the operating system different to those found on static devices but it changes constantly and rapidly.

This course guides the potential Android programmer through the Android programming maze by providing solid, real-world examples that build a complete understanding of the system.

Objectives

On successful completion of this course, participants will be able to:

  • Write and build apps for Android using Java in Android Studio
  • Deploy and run apps on the emulator and on real devices
  • Understand the major Android components
  • Access common hardware features like the camera
  • Interact with other useful components like the Contacts database
  • Perform unit tests and user-interface tests
  • Publish apps on Google Playstore

Audience

This course is aimed primarily at Java programmers who wish to create or maintain Android apps. Other members of the development team may also find it useful.

Prerequisites

Participants are expected to have a working knowledge of Java up to the level covered in the Java Programming course. Familiarity with Gradle is helpful but not essential. No knowledge of either Android or Android Studio is assumed.
