We can add sounds on various events like on item click ,button click etc. For playing sounds we use MediaPlayer object.
MediaPlayer class can be used to control playback of audio/video files and streams in the application.
1.For local resource.
Firstly to store the sound file we create a sub folder raw in the res folder. Then put your sound file in the raw folder.
The following code depicts how click sound is played when button is pressed. In this code sound is played on button click and stopped on another button click.
MediaPlayer mp;
mp = MediaPlayer.create(this, R.raw.click);//click sound is fetched from raw folder
public void onClick(View v)
{
// actions taken when Buttons are clicked
switch (v.getId())
{
case R.id.playBtn_id: // play click sound
mp.start();//Starts or resumes playback
//put your code here
break;
case R.id.stopBtn_id: // play click sound
mp.stop();//Stops a playback
//put your code here
break;
}
}
Similarly we can add sound in app anywhere we wish. We can explicitly start and stop a sound using mp.start() and mp.stop() .If we explicitly do not stop a sound file than it play till its completion.
2.Playing from a remote URL via HTTP streaming
This code shows you how you play audio from remote url :
String url = “http://……..”; // your URL here
MediaPlayer mediaPlayer = new MediaPlayer();
//setting audio stream type
mediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
mediaPlayer.setDataSource(url);//setting url as data source
mediaPlayer.prepare(); // for buffering
mediaPlayer.start();//starts playing
Hence, these are the two ways of playing sound using local and remote resources.
