    <p>Could someone show me or teach me how I can download 5 or more mp3 in a file and playing them in my app. I've searched about it but all of people how has asked this, nothing explained it well. I don't want to download only one mp3, but multiple mp3s in a file.here is main.java </p> <pre><code>public class StreamingMp3Player extends Activity implements OnClickListener, OnTouchListener, OnCompletionListener, OnBufferingUpdateListener{ private ImageButton buttonPlayPause; private SeekBar seekBarProgress; public EditText editTextSongURL; private MediaPlayer mediaPlayer; private int mediaFileLengthInMilliseconds; // this value contains the song duration in milliseconds. Look at getDuration() method in MediaPlayer class private final Handler handler = new Handler(); /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); initView(); } /** This method initialise all the views in project*/ private void initView() { buttonPlayPause = (ImageButton)findViewById(R.id.ButtonTestPlayPause); buttonPlayPause.setOnClickListener(this); seekBarProgress = (SeekBar)findViewById(R.id.SeekBarTestPlay); seekBarProgress.setMax(99); // It means 100% .0-99 seekBarProgress.setOnTouchListener(this); editTextSongURL = (EditText)findViewById(R.id.EditTextSongURL); editTextSongURL.setText(R.string.testsong_20_sec); mediaPlayer = new MediaPlayer(); mediaPlayer.setOnBufferingUpdateListener(this); mediaPlayer.setOnCompletionListener(this); } /** Method which updates the SeekBar primary progress by current song playing position*/ private void primarySeekBarProgressUpdater() { seekBarProgress.setProgress((int)(((float)mediaPlayer.getCurrentPosition()/mediaFileLengthInMilliseconds)*100)); // This math construction give a percentage of "was playing"/"song length" if (mediaPlayer.isPlaying()) { Runnable notification = new Runnable() { public void run() { primarySeekBarProgressUpdater(); } }; handler.postDelayed(notification,1000); } } @Override public void onClick(View v) { if(v.getId() == R.id.ButtonTestPlayPause){ /** ImageButton onClick event handler. Method which start/pause mediaplayer playing */ try { mediaPlayer.setDataSource(editTextSongURL.getText().toString()); // setup song from http://www.hrupin.com/wp-content/uploads/mp3/testsong_20_sec.mp3 URL to mediaplayer data source mediaPlayer.prepare(); // you must call this method after setup the datasource in setDataSource method. After calling prepare() the instance of MediaPlayer starts load data from URL to internal buffer. } catch (Exception e) { e.printStackTrace(); } mediaFileLengthInMilliseconds = mediaPlayer.getDuration(); // gets the song length in milliseconds from URL if(!mediaPlayer.isPlaying()){ mediaPlayer.start(); buttonPlayPause.setImageResource(R.drawable.button_pause); }else { mediaPlayer.pause(); buttonPlayPause.setImageResource(R.drawable.button_play); } primarySeekBarProgressUpdater(); } } @Override public boolean onTouch(View v, MotionEvent event) { if(v.getId() == R.id.SeekBarTestPlay){ /** Seekbar onTouch event handler. Method which seeks MediaPlayer to seekBar primary progress position*/ if(mediaPlayer.isPlaying()){ SeekBar sb = (SeekBar)v; int playPositionInMillisecconds = (mediaFileLengthInMilliseconds / 100) * sb.getProgress(); mediaPlayer.seekTo(playPositionInMillisecconds); } } return false; } @Override public void onCompletion(MediaPlayer mp) { /** MediaPlayer onCompletion event handler. Method which calls then song playing is complete*/ buttonPlayPause.setImageResource(R.drawable.button_play); } @Override public void onBufferingUpdate(MediaPlayer mp, int percent) { /** Method which updates the SeekBar secondary progress by current song loading from URL position*/ seekBarProgress.setSecondaryProgress(percent); } </code></pre>

    1. COWhat technology is your app written in? And what have you already done? Because I'm quite sure MP3 players are readily available in most technologies.

    2. CO@FrankvanPuffelen not in Java :) You'll need to use 3rd party libraries to support MP3 playback. See http://en.wikipedia.org/wiki/Java_Media_Framework#Alternatives For the downloading part, use `URLConnection` to get an InputStream.

    3. CO@LukasKnuth I'd call certain third party libraries readily available. ;-) But indeed, it depends on the technology. May I suggest that you convert your comment into an answer?
