[안드로이드 스튜디오] audio streaming 예제 1.1

이전 게시글(http://link2me.tistory.com/1391)에서 서버 파일 1개만 재생하는 걸 Spinner 기능을 이용하여 몇개 선택해서 듣어볼 수 있도록 수정해봤다.

스트리밍 기능이 동작되는 걸 확인할 수 있다.

파일을 테스트해보니 mp3, wav 파일은 스트리밍 재생이 되는데 flac, ape 파일은 재생을 못한다.

제어없이 바로 재생되는 것은  아래 메소드를 이용해도 된다.

public void StartMusic(String url) {         // HTTP스트리밍을 통한 원격의 URL에서 재생         try {             if(mediaPlayer!=null && mediaPlayer.isPlaying()){                 mediaPlayer.stop();                 mediaPlayer.reset();             }             mediaPlayer = new MediaPlayer();             mediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);             mediaPlayer.setDataSource(url);             mediaPlayer.prepareAsync();             mediaPlayer.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {                 @Override                 public void onPrepared(MediaPlayer mp) {                     mp.start();                 }             });         } catch (Exception e) {             Log.e("MusicPlayer", e.getMessage());         }     }

스트리밍이 잘 되는 걸 확인했으니, 서버 파일을 자동으로 인식해서 처리하는 걸 해봐야겠다.
