In the application I am currently writing, a user is able to select an entry from the database and play the contents of that entry: an entry is made up of a number of sound files (without a limit). In my application, I return the URI locations of the sound files of an entry (which have been stored in my database) in a List. The code is as follows:
public void audioPlayer() {
// set up MediaPlayer
MediaPlayer mp = new MediaPlayer();
DatabaseHandler db = new DatabaseHandler(this);
Entry retrieveEntry = new Entry();
retrieveEntry = db.getEntry();
List<String> path = retrieveEntry.getAudioUri();
path.size();
System.out.println("PATH SIZE: " +path.size());
System.out.println("FILEZ: " + path);
Iterator<String> i = path.iterator();
String myAudio;
int count = 0;
while (i.hasNext()) {
System.out.println(count);
myAudio = i.next();
System.out.println("MY AUDIO: " + myAudio);
MediaPlayer player = MediaPlayer.create(this, Uri.parse(myAudio));
player.start();
player.stop();
player = MediaPlayer.create(this, Uri.parse(myAudio));
player.start();
count++;
}
}
My users require that there be user input for playing a file - is there a way to play the first file, then wait for the user to press the button, then play the second file, then wait for the user to press the button, etc.? At the moment, when the play button is pressed, all of the sound files that have been returned get played at the same time, rather than one after the other.
Thanks in advance for any help provided!
You can use this class to play a playlist. This will start one audio, when that audio finishes, it will start playing next audio till the end of the list. If you want to play the playlist in looping i.e start first audio after reaching end, then pass isLooping=true in startPlayingPlaylist(list,looping)
AudioPlayer player = new AudioPlayer();
player.startPlayingPlaylist(list, false);
Class
public class AudioPlayer{
MediaPlayer player = null;
ArrayList<String> playlist = null;
int position = 0;
public AudioPlayer() {
super();
// TODO Auto-generated constructor stub
}
public void startPlayingPlaylist(ArrayList<String> list, boolean looping){
playlist = list;
if(player!=null){
player.release();
}
if(playlist!=null && playlist.size()>0){
player = MediaPlayer.create(LMApplicaton.getInstance(),Uri.parse(playlist.get(position)));
player.setWakeMode(LMApplicaton.getInstance(), PowerManager.PARTIAL_WAKE_LOCK);
player.setLooping(looping);
player.start();
// Set onCompletion listener
player.setOnCompletionListener(new OnCompletionListener() {
#Override
public void onCompletion(MediaPlayer mp) {
position = position+1;
if(position<playlist.size()){
try {
player.reset();
player.setDataSource(playlist.get(position));
player.prepareAsync();
} catch (IllegalArgumentException e) {
e.printStackTrace();
} catch (IllegalStateException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
} else if(player.isLooping()==true){
position = position%playlist.size();
try {
player.reset();
player.setDataSource(playlist.get(position));
player.prepareAsync();
} catch (IllegalArgumentException e) {
e.printStackTrace();
} catch (IllegalStateException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}
else if(player.isLooping()==false){
player.release();
player = null;
}
}
});
player.setOnPreparedListener(new OnPreparedListener() {
#Override
public void onPrepared(MediaPlayer mp) {
player.start();
}
});
}
}
public void pause(){
if(player!=null && player.isPlaying()){
player.pause();
}
}
public void play(){
if(player!=null && player.isPlaying()==false){
player.start();
}
}
public boolean isPlaying(){
return player.isPlaying();
}
public void release(){
if(player!=null){
player.release();
}
}
}
Edit:
The class below receives a list of audios, then plays first Audio. It plays next audio when user calls startNextAudio() You can use any one of these according to your requirements
public class AudioPlayer{
MediaPlayer player = null;
ArrayList playlist = null;
int position = 0;
public AudioPlayer() {
super();
// TODO Auto-generated constructor stub
}
public void startPlayingPlaylist(ArrayList<String> list){
playlist = list;
if(player!=null){
player.release();
}
if(playlist!=null && playlist.size()>0){
player = MediaPlayer.create(LMApplicaton.getInstance(),Uri.parse(playlist.get(position)));
player.setWakeMode(LMApplicaton.getInstance(), PowerManager.PARTIAL_WAKE_LOCK);
player.start();
// Set onCompletion listener
player.setOnPreparedListener(new OnPreparedListener() {
#Override
public void onPrepared(MediaPlayer mp) {
player.start();
}
});
}
}
public void startNextAudio(){
position = position+1;
if(position<playlist.size()){
try {
player.reset();
player.setDataSource(playlist.get(position));
player.prepareAsync();
} catch (IllegalArgumentException e) {
e.printStackTrace();
} catch (IllegalStateException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
} else if(player.isLooping()==true){
position = position%playlist.size();
try {
player.reset();
player.setDataSource(playlist.get(position));
player.prepareAsync();
} catch (IllegalArgumentException e) {
e.printStackTrace();
} catch (IllegalStateException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}else{
Log.i("AudioPlayer","Playlist reached at the end");
}
}
public void pause(){
if(player!=null && player.isPlaying()){
player.pause();
}
}
public void play(){
if(player!=null && player.isPlaying()==false){
player.start();
}
}
public boolean isPlaying(){
return player.isPlaying();
}
public void release(){
if(player!=null){
player.release();
}
}
}
One approach would be to implement the MediaPlayer.OnCompletionListener interface. This gives you the MediaPlayer.onCompletion() callback method which you could use like so:
#Override
public void onCompletion(MediaPlayer mp) {
if (i.hasNext) {
// ...hand mp the next file
// ...show the user the 'play next' button
}
}
Note you also will need to call the MediaPlayer.setOnCompletionListener() method in your setup.

I'm using the following code to play music when an user selects a song from the listview.
if (mMediaPlayer.isPlaying()) {
mMediaPlayer.reset();
try {
mMediaPlayer.setDataSource(MainActivity.localTrackList.get(MainActivity.currentOffset).getPath());
} catch (IOException e) {
e.printStackTrace();
}
mMediaPlayer.prepareAsync();
} else {
mMediaPlayer = new MediaPlayer();
try {
mMediaPlayer.setDataSource(MainActivity.localTrackList.get(MainActivity.currentOffset).getPath());
} catch (IOException e) {
e.printStackTrace();
}
mMediaPlayer.prepareAsync();
}
mMediaPlayer.reset(); is calling the onCompletionListener. In my oncompletionListener, I'm playing the next song and hence instead of playing the selected song, it plays the next song in the listview. Is there by any ways I can prevent calling onCompletionListener and play only the song that's selected from listview?
You could do something like this.
boolean isMediaPlayerReset = false;
MediaPlayer mMediaPlayer = null;
//on list item click
if(mMediaPlayer.isPlaying()){
isMediaPlayerReset = true;
mMediaPlayer.reset();
try {
mMediaPlayer.setDataSource("/path");
} catch (IOException e) {
e.printStackTrace();
}
mMediaPlayer.prepareAsync();
}
mMediaPlayer.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
#Override
public void onCompletion(MediaPlayer mp) {
if(isMediaPlayerReset){
isMediaPlayerReset = false;
return;
}
//play next song
}
});
I have searched and researched stackoverflow and google but can't find any answer to MY question. I've found other question and answers but that were related to sounds saved in the app but I'm creating an app which gets data from Parse server, so it gets mp3 files and display these in listview and than when an item is clicked it plays that track. But here comes the problem: When you play a sound and click on another one, the first just doesn't stop and the second starts to play.
I have tried with the following code but it's just not working.
Here's my code:
play.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
final MediaPlayer mediaPlayer = new MediaPlayer();
final MediaPlayer scndmediaPlayer = new MediaPlayer();
mediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
scndmediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
if (mediaPlayer.isPlaying()) {
Toast.makeText(getContext(), "First is playing", Toast.LENGTH_SHORT).show();
try {
mediaPlayer.stop();
scndmediaPlayer.setDataSource(audioFileURL);
scndmediaPlayer.prepare();
scndmediaPlayer.start();
//soundtoolbar.setTitle(name);
} catch (IllegalArgumentException e1) {
e1.printStackTrace();
} catch (SecurityException e1) {
e1.printStackTrace();
} catch (IllegalStateException e1) {
e1.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
} else {
try {
if (scndmediaPlayer.isPlaying()){
scndmediaPlayer.stop();
}
Toast.makeText(getContext(), "First is starting", Toast.LENGTH_SHORT).show();
mediaPlayer.setDataSource(audioFileURL);
mediaPlayer.prepare();
mediaPlayer.start();
soundtoolbar.setTitle(name);
} catch (IllegalArgumentException e1) {
e1.printStackTrace();
} catch (SecurityException e1) {
e1.printStackTrace();
} catch (IllegalStateException e1) {
e1.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}
playPause.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if (mediaPlayer.isPlaying() || scndmediaPlayer.isPlaying()) {
mediaPlayer.pause();
scndmediaPlayer.pause();
playPause.setBackground(getContext().getDrawable(R.drawable.ic_play_arrow_white_24dp));
} else {
mediaPlayer.start();
scndmediaPlayer.start();
playPause.setBackground(getContext().getDrawable(R.drawable.ic_pause_white_24dp));
}
}
});
}
});
I've created 2 mediaplayers with the code above and when user clicks the play button it first checks if any of the player is running.
I'm trying to achieve the following: When user clicks the play button it checks if the (1st) mediaPlayer is running or not. If it's running, it has just to stop it and launch (2nd) scndmediaPlayer or viceversa... if second is playing it stops that and launch first one. so it will create a loop: 1st is playing? User clicks another button stop first. Launch second. User clicks another button. First is playing? No. Second is playing? Yes. Stop the second and launch the first.
But can't find where is the problem in my code.
Please help me with this. I'm trying to resolve it from 2 days but I'm unable...
Thanks :)
EDIT: I tried using one MediaPlayer and do the following: Check if mediaplayer is playing! No it isn't playing. Start it. User clicks the button again and it stops the mediaplayer and start it with new audioFileUrl. BUT. MediaPlayer is forgetting that it's playing. Seems like it just starts the track and than forget and to check if it's true i set a Toast: when mediaplayer isn't playing the toast shows and it's showing every time I click a track in the list which means it forget that it has a track which is playing...
EDIT 2: I managed to do the following: It plays the track. User clicks another track. It stops the mediaplayer but doesn't play the new track. User click once again. It plays the new track. User clicks the new track and the app crashes...

Somebody please help...
i suggest you to checkout SoundPool . İt ll helps you. And one more , may be you ll put media urls to array or something like this.And use one mediaPlayer By the way, you ll avoid from two mediaPlayer and avoid from memory leak.

I have a problem when playing an mp3 in android, is something like a delay or a lag, ex:
if I have to reproduce the following: "Hello, how are you?", it only plays "how are you?" or says very low the "hello".
It happens in a ViewSonic V220 its a 22" tablet, in most of other devices, it works fine, but is in that one that seems to fail.
Its weird, becouse other apps(like youtube or media player) works fine.
This is my code, maybe i am doing something wrong:
public class SoundManager implements MediaPlayer.OnPreparedListener, MediaPlayer.OnCompletionListener {
private Parent mParent;
private MediaPlayer mediaPlayer;
String[] mp3_array;
int counter = 0;
public SoundManager(Parent parent) {
mParent = parent;
}
public void playSound(String[] url) throws IllegalArgumentException,
IllegalStateException, IOException {
mp3_array = url;
mediaPlayer = new MediaPlayer();
mediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
if (mediaPlayer.isPlaying()) {
mediaPlayer.reset();
}
mediaPlayer.setDataSource(url[0]);
mediaPlayer.setOnCompletionListener(this);
mediaPlayer.setOnPreparedListener(this);
mediaPlayer.prepareAsync();
}
public void stopMediaPlayer() {
if (mediaPlayer != null) {
mediaPlayer.release();
mediaPlayer = null;
mp3_array = null;
counter = 0;
}
}
#Override
public void onCompletion(MediaPlayer mp) {
try {
Integer c = counter;
if (mp3_array != null && counter + 1 < mp3_array.length) {
mp.reset();
mp.setOnCompletionListener(this);
mp.setOnPreparedListener(this);
counter += 1;
mp.setDataSource(mp3_array[counter]);
mediaPlayer.prepareAsync();
} else {
if (mParent != null)
mParent.invokeJs("playSoundEnded()");
mp.release();
mp = null;
mp3_array = null;
counter = 0;
}
} catch (IllegalArgumentException e) {
// TODO Auto-generated catch block

I am developing one application where i want to play live stream radio. I have an url using which i will stream the radio and play. I have a play button by clicking which i want to play the radio. For that, i have written some code which is not at all working. Here is my code:
mp = new MediaPlayer();
try {
mp.setOnPreparedListener(this);
Log.d("Testing", "start111");
mp.setAudioStreamType(AudioManager.STREAM_MUSIC);
String url="xxxxxx";
mp.setDataSource(url);
mp.prepareAsync();
} catch (IllegalArgumentException e) {
e.printStackTrace();
Log.d("Testing", "Exception ::: 1111 "+e.getMessage());
} catch (IllegalStateException e) {
Log.d("Testing", "Exception ::: 2222 "+e.getMessage());
e.printStackTrace();
} catch (IOException e) {
Log.d("Testing", "IOException ::: 3333 "+e.getMessage());
e.printStackTrace();
}
Can anyone please help me??
You can find good information regarding radio streaming.
Github radio streaming example
and also there is a question in SOF which can also be helpful
Stackoverflow radio streaming example
Hope it will help. thanks
Try this.

Memory is extremely limited on mobile devices, so you wouldn't want to load songs you're not going to play. So what you should do is find all of the audio files in that folder, and then choose one and THEN load and play it.
You just need to stop the current player and create a new instance.
MediaPlayer player = MediaPlayer.create(this, Uri.parse("Path/To/Media"));
player.start();
// change track
player.stop();
player = MediaPlayer.create(this, Uri.parse("New/Path/To/Media"));
player.start();
