I have a problem with changing URL of live stream in the MediaPlayer instance. When I tap on a ListView item for a first time, live streaming is started and video is displayed, but if I click on another object in the ListView, stream is not changed, the same stream continues to play which was executed at first time.
public class MainActivity extends AppCompatActivity implements SurfaceHolder.Callback, MediaPlayer.OnPreparedListener, VideoControllerView.MediaPlayerControl {
SurfaceView videoSurface;
MediaPlayer player;
VideoControllerView controller;
ArrayList<Channel> channels;
Channel clickedChannel;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
videoSurface = (SurfaceView) findViewById(R.id.videoSurface);
SurfaceHolder videoHolder = videoSurface.getHolder();
videoHolder.addCallback(this);
controller = new VideoControllerView(this);
player = new MediaPlayer();
channels = new ArrayList<Channel>();
CreateChannels();
ListView lvMain = (ListView) findViewById(R.id.lvMain);
CustomAdapter adapter = new CustomAdapter(this, channels);
lvMain.setAdapter(adapter);
lvMain.setOnItemClickListener(new AdapterView.OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
Log.d(LOG_TAG, "itemClick: position = " + position + ", id = "
+ id);
clickedChannel = channels.get(position);
}
}
}
PlayStream(clickedChannel.Streams[0].URL);
}
});
}
public void PlayStream(String URL) {
try {
player.setAudioStreamType(AudioManager.STREAM_MUSIC);
player.setDataSource(this, Uri.parse(URL));
player.setOnPreparedListener(this);
player.prepareAsync();
player.start();
} catch (IllegalArgumentException e) {
e.printStackTrace();
} catch (SecurityException e) {
e.printStackTrace();
} catch (IllegalStateException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}
// missed code
#Override
public boolean onTouchEvent(MotionEvent event) {
controller.show();
return false;
}
#Override

}
#Override

Solved my problem by recreating player instance every time

the issue is, I have checked whether media player is null or not, if not I have applied release() method but still when I select another song to play, it plays new song but it doesn't stop the previous one. While playing next or previous on click also works fine. so why it is not detecting that mediaplayer is playing.
here is java code.

so do suggest reason why this error is taking place, and it is playing two or multiple song simultaneously.
all you have to do is, just declare mediaplayer variable public static and when you start activity to play song just check for media player is null or not and then release it
My requirement is to change video inside video player with animation. When a person taps on "change" button the video in media player will get change with a new one and the old will end up with zoom in animation. I am able to implement this functionality with the help of texture view but I am getting one issue that there is a glitch while changing the video. is there any way I can make it more smooth?

textureView.setSurfaceTextureListener(this);
zoomAnimation = AnimationUtils.loadAnimation(VideoVieww.this, R.anim.zomm_out);
mButton = findViewById(R.id.change);
mButton.setOnClickListener(view -> {
if (mMediaPlayer.isPlaying()) {
mMediaPlayer.stop();
mMediaPlayer.release();
mMediaPlayer = null;
}
textureView.startAnimation(zoomAnimation);
try {
mMediaPlayer = new MediaPlayer();

e.printStackTrace();

}
#Override

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.

Please do try the code below and call the given method at the on create of your activity or at the onclick listener of your button. Remember to handle the stop and start button the imgV is an imageView for my button.

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) {

}
} else if(player.isLooping()==true){
position = position%playlist.size();
try {

} catch (IllegalArgumentException e) {

} catch (IllegalStateException e) {

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
}
