Simple MediaPlayer Sample

This sample demonstrates the use of MediaPlayer. Here are some important things this sample highlights:

  • Media playback position and duration are synchronized with a Seekbar in the UI.
  • If the user manually changes the Seekbar position the MediaPlayer playback position is adjusted accordingly.
  • State machine transitions for MediaPlayer are displayed in the UI.
  • MP3 files are loaded from the raw/res/ folder (no streaming over network).

The following articles describe what this sample does in detail:

  1. MediaPlayer introduction
  2. Buiding the app
  3. Synchronizing with the SeekBar
