73.10 Implementing the playAudio() method

The playAudio() method will simply create a new MediaPlayer instance, assign the audio file located on the SD card as the data source and then prepare and start the playback:

public void playAudio (View view) throws IOException

{

       playButton.setEnabled(false);

       recordButton.setEnabled(false);

       stopButton.setEnabled(true);

 

       mediaPlayer = new MediaPlayer();

       mediaPlayer.setDataSource(audioFilePath);

       mediaPlayer.prepare();

       mediaPlayer.start();

}
