Introduction to Google Android Software Platform


Ron Fredericks writes: LectureMaker was on scene filming Marko Gargenta deliver his Introduction to Google’s Android Software Platform during the September 3′rd regular meeting of the Software Development Forum (SDForum) Mobile Internet Special Interest Group meeting. Peter Lam was the host representing the Software Development Forum for this meeting, while Peter’s co-host Joe Jasin was traveling. The site for the event was located at the Orrick Law Office in Menlo Park with very friendly facilitators and signage to help a new visitor like me easily locate the meeting within the three building complex.

Marko is an industry expert in Android, a technical and business trainer for Android and other open-source technologies, co-author of PHP and MySQL by Example published by Prentice Hall, leader of the San Francisco Android User Group, founder of a leading technical training company called Marakana, and more…

 The presentation covers both a business and developer perspective with several practical examples and live demonstrations.  See the list of quesitons and main topics represented as red navigation dots embedded in the video, as well as a time line near the end of this post.

Handset users:

  • Learn more about the growing Android software marketplace and what platform features to look for on your next smartphone
  • Learn about the three types of Android license that may ship with a phone
  • Learn what a “long click” is and how to use it to customize widgets on your phone

  • One of the few platforms that can run services in the background (multi-tasking apps)
  • Battery performance
  • Security
  • Internet
  • Networking
  • Web browsers based on WebKit
  • How developers emulate the on-phone camera and other on-board sensors
  • Developing an application with content, resources, and code
  • Easier access to GPS (global positioning services)
  • SQL database

Here is a time line for the video presentation

Have you noticed all those red naviagtion dots embedded into LectureMaker’s video player? These dots allow a viewer to quickly get a sense of what content is included in the video. “I hate to be asked to watch a video – especially a long video – with no idea of whether I should take the time to watch it or note” – Ron Fredericks, designer of LectureMaker’s video player.  With these navigation dots, the nature of “Watch my video” has really changed!
