Android - Devoxx 2011 - Performance Usability keynote

A few things I learned on performance and usability for Android at the Devoxx Conference in 2011:

  1. Dont block the userthread - use Asynctask, Thread or Service instead
  2. Entertain the user while waiting. Show something spinning like a progressdialog, spinner, etc.
  3. Allow the user to cancel a heavy task
  4. Use a passive location provider instead or last known location vs. polling the location 
  5. Tool to measure performance - Traceview
