It has just one issue that it plays multiple songs if selected, rest everything works fine

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

AndroidStudio MediaPlayer methods pause() and stop() doesnt work correctly

I'm working in a music player that download a File from firebase and init media player with this LOCALFILE. I've trying to STREAM_AUDIO with Media Player, but couldn't make pause() work properly with online streaming. Now,
pause/player button only call start() and doesn't pause(); stop() reinit audio immediately. How do I fix that?
Public class PerformanceActivity extends Activity {
private ImageButton playerPerf, stopPerf;
protected MediaPlayer mMediaPlayer;
protected ProgressDialog progressDialog;
private static String url = "https://firebasestorage.go....";
private File ARQUIVO_AUDIO;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_perfomance2);
playerPerf = findViewById(R.id.perfPlayId);
stopPerf = findViewById(R.id.perfStopId);
try {
executarProgressDialog();
FirebaseStorage storage = FirebaseStorage.getInstance();
// Create a storage reference from our app
StorageReference storageRef = storage.getReferenceFromUrl(url);
final File localFile = File.createTempFile("audios", ".mp3");
Log.e("MEDIAPLAYER", "localfile criado com sucesso");
storageRef.getFile(localFile).addOnSuccessListener(new OnSuccessListener<FileDownloadTask.TaskSnapshot>() {
#Override
public void onSuccess(FileDownloadTask.TaskSnapshot taskSnapshot) {
try {
mMediaPlayer = new MediaPlayer();
mMediaPlayer.setDataSource(localFile.toString());
Log.e("MEDIAPLAYER","Media player instanciado");
mMediaPlayer.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
#Override
public void onPrepared(MediaPlayer mp) {
}
});
mMediaPlayer.prepareAsync();
} catch (IOException e) {
Log.e("MEDIAPLAYER",e.toString());
}
}
}).addOnFailureListener(new OnFailureListener() {
#Override
public void onFailure(#NonNull Exception e) {
Toast.makeText(PerfomanceActivity2.this, "ooops falha no download", Toast.LENGTH_LONG).show();
// progressDialog.dismiss();
Log.e("MEDIAPLAYER ERROR", e.toString());
}
});
} catch (IOException e) {
e.printStackTrace();
}
progressDialog.dismiss();
// Botao play/pause que executa o streaming
playerPerf.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if (mMediaPlayer!=null) {
if (mMediaPlayer.isPlaying()) {
mMediaPlayer.pause();
Log.e("MEDIAPLAYER", "metodo pause chamado");
}
if (!mMediaPlayer.isPlaying()) {
mMediaPlayer.start();
Log.e("MEDIAPLAYER", "start chamado");
}
}
}
});
// Pause o STREAMING e reinicializa o MediaPlayer
stopPerf.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
try {
if (mMediaPlayer != null) {
mMediaPlayer.stop();
mMediaPlayer.prepare();
}
} catch (Exception e) {
Log.e("Audio erro", e.toString());
}
}
});
}
//libera espaço da memória quando a Activity é destruida
#Override
public void onDestroy() {
if (mMediaPlayer != null) {
mMediaPlayer.stop();
mMediaPlayer.release();
mMediaPlayer = null;
if (progressDialog != null) {
progressDialog.cancel();
}
}
super.onDestroy();
}
//Metodo que executa um ProgressDialog durante o download do audio
void executarProgressDialog() {
try {
progressDialog = new ProgressDialog(PerfomanceActivity2.this);
progressDialog.setMessage("Moluscos trabalhando...");
progressDialog.setProgressStyle(ProgressDialog.STYLE_SPINNER);
progressDialog.setTitle("Preparando meditação");
progressDialog.setCancelable(false);
progressDialog.show();
} catch (Exception e) {
Log.e("ProgressDialog Error", "Erro ao inicializar ProgressDialog");
}
}
}

There is an obvious logic problem in playerPerf.OnClickListener.
if (mMediaPlayer!=null) {
if (mMediaPlayer.isPlaying()) {
mMediaPlayer.pause();
Log.e("MEDIAPLAYER", "metodo pause chamado");
}
if (!mMediaPlayer.isPlaying()) { // <= always true because you pause it if not.
mMediaPlayer.start();
Log.e("MEDIAPLAYER", "start chamado");
}
}
The state mMediaPlayer.isPlaying wasn't separate correctly, which caused => if isPlaying then pauses it, directly considering if !isPlaying is always paused. So it always starts it no matter whether it was playing or not.
=> To solve it:
Just add a else instead of considering mMediaPlayer.isPlaying() twice.
if (mMediaPlayer!=null) {
if (mMediaPlayer.isPlaying()) {
mMediaPlayer.pause();
Log.e("MEDIAPLAYER", "metodo pause chamado");
} else { //<= change it to else
//if (!mMediaPlayer.isPlaying()) { // <= remove the second if
mMediaPlayer.start();
Log.e("MEDIAPLAYER", "start chamado");
}
}

Android MediaPlayer change live stream's URL

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
public void surfaceCreated(SurfaceHolder holder) {
player.setDisplay(holder);
}
#Override
public void onPrepared(MediaPlayer mp) {
controller.setMediaPlayer(this);
controller.setAnchorView((FrameLayout) findViewById(R.id.videoSurfaceContainer));
player.start();
}
}

Solved my problem by recreating player instance every time
public void PlayStream(String URL) {
releaseMP();
try {
player = new MediaPlayer();
player.setDisplay(videoHolder);
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();
}
}
private void releaseMP() {
if (player != null) {
try {
player.release();
player = null;
} catch (Exception e) {
e.printStackTrace();
}
}
}
#Override
protected void onDestroy() {
super.onDestroy();
releaseMP();
}
#Override
public void surfaceCreated(SurfaceHolder holder) {

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

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.
private MediaPlayer player;

}
});
}

}
boolean isPlaying = true;
private void startPlaying() {
