Media Player loading media again and again

I am making a chat application and I have implemented the feature for sending audio messages.But here I find one thing which I don't want it to happen.It is that whenever my adapter gets updated,The media player starts loading again. In this way there will be an issue for if someone is listening to an audio and the user at other end sends a message ,the media player stops and it loads again.Here is the code of my adapter.
final MediaPlayer mediaPlayer;
mediaPlayer = new MediaPlayer();
mediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
handler = new Handler();
try {
mediaPlayer.setOnCompletionListener(mediaPlayer1 -> {
mediaPlayer1.stop();
binding.audioSeekbar.setProgress(0);
});
if (mediaPlayer.isPlaying()){
mediaPlayer.stop();
mediaPlayer.release();
}
mediaPlayer.setDataSource(finalUrlToLoad[1]);
mediaPlayer.setVolume(1f, 1f);
mediaPlayer.prepareAsync();
mediaPlayer.setOnPreparedListener(mediaPlayer1 -> {
int totalDuration = mediaPlayer1.getDuration();
binding.totalDurationAudio.setText(createTimeLabel(totalDuration));
binding.loadingAudio.setVisibility(GONE);
binding.playPauseAudio.setVisibility(VISIBLE);
});
} catch (IOException e) {e.printStackTrace();}
binding.playPauseAudio.setOnClickListener(view -> {
if (mediaPlayer.isPlaying()){
handler.removeCallbacks(runnable);
mediaPlayer.pause();
binding.playPauseAudio.setImageResource(R.drawable.pause_to_play);
Drawable drawable = binding.playPauseAudio.getDrawable();
if( drawable instanceof AnimatedVectorDrawable) {
AnimatedVectorDrawable animation = (AnimatedVectorDrawable) drawable;
animation.start();
}
}else {
mediaPlayer.seekTo(binding.audioSeekbar.getProgress());
mediaPlayer.start();
handler.post(runnable);
binding.playPauseAudio.setImageResource(R.drawable.play_to_pause);
Drawable drawable = binding.playPauseAudio.getDrawable();
if( drawable instanceof AnimatedVectorDrawable) {
AnimatedVectorDrawable animation = (AnimatedVectorDrawable) drawable;
animation.start();
}
}
});
runnable = () -> {
int totalTime = mediaPlayer.getDuration();
binding.audioSeekbar.setMax(totalTime);
int currentPosition = mediaPlayer.getCurrentPosition();
binding.audioSeekbar.setProgress(currentPosition);
binding.totalDurationAudio.setText(createTimeLabel(totalTime));
Log.d("time", String.valueOf(currentPosition));
handler.postDelayed(runnable,1000);
};
binding.audioSeekbar.setOnSeekBarChangeListener(new SeekBar.OnSeekBarChangeListener() {
#Override
public void onProgressChanged(SeekBar seekBar, int i, boolean b) {
if (b){
mediaPlayer.seekTo(i);
seekBar.setProgress(i);
}
}
#Override
public void onStartTrackingTouch(SeekBar seekBar) {
}
#Override
public void onStopTrackingTouch(SeekBar seekBar) {
}
});
mediaPlayer.setOnBufferingUpdateListener((mediaPlayer1, i) -> binding.audioSeekbar.setSecondaryProgress(i));
Here finalurltoload[1] is the url for the audio.
Now what do I need to do in order to prevent loading it again and again.
I will be really grateful to who answer this question.
Thanks😊.

It's hard to tell from this code but I assume this is all set in your onBind event? If so, then this means every time RecyclerView creates a new holder and binds it, the associated media will be prepped and loaded, and whichever is the 'last holder to have been called with onBind, "wins" (and is what MediaPlayer will be loaded with). Since by default RecyclerView typically creates multiple holders up front, you are seeing your MediaPlayer being "loaded" multiple times.
You probably just don't want to do the initialization of each audio message in the onBind. Instead, just use the onBind event to initialize state variables (duration, progress, etc.) to some default value, hide them and bind the specific audio Uri. Then when the user takes some action like tapping on the holder, you unhide an indeterminate progress bar while the initialization takes place, and in the onPrepared() event unhide the state information (duration, progress, seekbar, etc.), and finally hide the indeterminate progress bar and start the audio.
I assume you are also sending over the sound file as part of your messaging app (i.e. not storing it on the web somewhere in a central location?), and this file gets stored in an app-specific storage location? If so, you don't need to worry about persisting the permission to that URI, but if that isn't the case you will.

First extract the media player code into singleton class like AudioManager.
Add few method like setMediaUpdateListener that set a callback for seek duration. and togglePlayPause to play or pause the audio.
Passed the message id or any unique identifier to the audio manager while playing the video.
In Adapter class onBind Method.
First Compare the id and playing Id is same like AudioManager.getInstance().isPlaying(messageId);
If yes then set the seekUpdatelistner to the audio manager class.
also update the play/pause icon based on AudioManager.isPlaying() method.
3.if user play other message by clicking play button. call AudioManager.play(message) method.In which we release the previous message and play the new one.
If current message is not playing then reset the view on non-playing state.
If Auto play is enabled then you need to check if audioManager is free then only you can play the last message otherwise ignored.
Like a class who are managing the audio for you and store all the state.
class AudioManager {
public static AudioManager instance;
final MediaPlayer mediaPlayer;
private AudioListener audioListener;
private Uri currentPlaying;
public AudioManager getInstance() {
if (instance == null) {
instance = new AudioManager();
}
}
public void play(Uri dataUri) {
if (mediaPlayer != null && currentPlaying == null || currentPlaying.equals(dataUri)) {
if (!mediaPlayer.isPlaying) {
mediaPlayer.play();
}
return;
} else if (mediaPlayer != null) {
mediaPlayer.stop();
mediaPlayer.release();
}
mediaPlayer = new MediaPlayer();
mediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
handler = new Handler();
try {
mediaPlayer.setOnCompletionListener(mediaPlayer1 -> {
mediaPlayer1.stop();
sendProgress(0);
});
if (mediaPlayer.isPlaying()) {
mediaPlayer.stop();
mediaPlayer.release();
}
mediaPlayer.setDataSource(dataUri;
mediaPlayer.setVolume(1f, 1f);
mediaPlayer.prepareAsync();
mediaPlayer.setOnPreparedListener(mediaPlayer1 -> {
int totalDuration = mediaPlayer1.getDuration();
sendTotalDuration(totalDuration);
});
} catch (IOException e) {
e.printStackTrace();
}
}
public void pause() {
// update the pause code.
}
public void sendProgress(int progress) {
if (audioListener != null) {
audioListener.onProgress(progress);
}
}
public void sendTotalDuration(int duration) {
if (audioListener != null) {
audioListener.onTotalDuraration(duration);
}
}
public void AudioListener(AudioListener audioListener) {
this.audioListener = audioListener;
}
public interface AudioListener {
void onProgress(int progress);
void onTotalDuraration(int duration);
void onAudioPlayed();
void onAudioPaused():
}
}

My android App stop playing sound on button tap after some time

Hello there, i have just created a basic android app which plays different musics on button tap..
The app just worked fine for the first couple of seconds but when i just keep on tapping and tapping , at some point it stops playing the music and just crashed...
I am unable to figure out what the problem is ..Please help me make it work..
Thanks.
Here is my code :-
public class MainActivity extends AppCompatActivity {
MediaPlayer mediaPlayer;
public void PlayMusic(View view)
{
int ID = view.getId();
String NameID = view.getResources().getResourceEntryName(ID);
int sound= getResources().getIdentifier(NameID,"raw","com.example.pickachu.mypatatap");
mediaPlayer = MediaPlayer.create(this,sound);
mediaPlayer.start();
}
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
}

The sound is not playing after multiple taps because you must be getting IllegalStateException because you are not releasing the Mediaplayer object and Mediaplayer Lifecycles are not managed properly when you tap multiple times.
You can use setOnCompletionListener(MediaPlayer.OnCompletionListener listener) to release mediaPlayer after completion of sound as:
mediaPlayer = MediaPlayer.create(this,sound);
mediaPlayer.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
#Override
public void onCompletion(MediaPlayer mp) {
mp.reset();
mp.release();
mediaplayer = null;
}
});
mediaPlayer.start();

pass uri instead string
mediaPlayer= MediaPlayer.create(this, Uri.parse(Environment.getExternalStorageDirectory().getPath()+ "/Music/music.mp3"));
mediaPlayer.setLooping(true);
mpintro.start();

How can I download mp3 files and play them in my app?

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
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);
}

You'll need to use 3rd party libraries to support MP3 playback, as it is not included in the standard library. See Wikipedia for a list of alternatives.
For the downloading part, use an URLConnection to get an InputStream on the file and write it to a FileOutputStream. This might help, too: Working unbuffered Streams

Muting a video in a VideoView

I'm playing a video (from youtube) using a VideoView, like this:
VideoView video = (ViewView) this.findViewById(R.id.youtube_video);
MediaController controllers = new MediaController(this);
controllers.setAnchorView(video);
video.setMediaController(controllers);
video.setVideoURI(videoUri);
video.start()
I would like to be able to mute the video, but so far the only thing I found is:
AudioManager audioManager = (AudioManager) this.getSystemService(Context.AUDIO_SERVICE);
audioManager.setStreamMute(AudioManager.STREAM_MUSIC, true);
Which works fine in that the video is muted, but the problem is that all of the streamed music is muted, and if there's another video (or audio) which I want to play it's also muted.
Is there a way to just target the specific stream to be muted?
Thanks.

After digging into every possible source of information I managed to find, I came up with the following solution and thought it might benefit others in the future:
public class Player extends VideoView implements OnPreparedListener, OnCompletionListener, OnErrorListener {
private MediaPlayer mediaPlayer;
public Player(Context context, AttributeSet attributes) {
super(context, attributes);
this.setOnPreparedListener(this);
this.setOnCompletionListener(this);
this.setOnErrorListener(this);
}
#Override
public void onPrepared(MediaPlayer mediaPlayer) {
this.mediaPlayer = mediaPlayer;
}
#Override
public boolean onError(MediaPlayer mediaPlayer, int what, int extra) { ... }
#Override
public void onCompletion(MediaPlayer mediaPlayer) { ... }
public void mute() {
this.setVolume(0);
}
public void unmute() {
this.setVolume(100);
}
private void setVolume(int amount) {
final int max = 100;
final double numerator = max - amount > 0 ? Math.log(max - amount) : 0;
final float volume = (float) (1 - (numerator / Math.log(max)));
this.mediaPlayer.setVolume(volume, volume);
}
}
It seems to working well for me, acting just like a VideoView with mute/unmute functionality.
It's possible to make the setVolume method public so that volume can be controlled outside of the scope of the class, but I just needed mute/unmute to be exposed.

put this code in oncreate() and also in onresume() for handle video view in better way...
VideoView videoview = (VideoView) findViewById(R.id.videoview);
videoview.setVideoPath(videopath);
videoview.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
#Override
public void onPrepared(MediaPlayer mp) {
mp.setVolume(0f, 0f);
mp.setLooping(true);
}
});
videoview.start();

If you are coding in kotlin, Just use this line of code
videoView.setOnPreparedListener { video->
video.setVolume(0f,0f)
}

I have a simpler method, by doing this you will have a mute/unmute button (this can be used for audio and videos);
//set global variable
//private Button mMuteButton;
//private static int aux = 0;
//private AudioManager mAudioManager;
//set the Mute button on clickListener
mMuteButton.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
mAudioManager = (AudioManager)getSystemService(Context.AUDIO_SERVICE);
if(aux % 2 == 0){
mAudioManager.setStreamVolume(AudioManager.STREAM_MUSIC, 100, 0);
aux++;
} else {
mAudioManager.setStreamVolume(AudioManager.STREAM_MUSIC, 0, 0);
aux++;
}
}
});
}

when video finished go back to activity

I have some videos using videoView. everything is running well, but when the video is finished nothing happens, the phone stay on dark screen waiting to pres play again or the blink back on the phone.
I want that when videos is finished, go back to the activity before. this is my code.
public class chapterone extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
this.setContentView(R.layout.videoplayer);
VideoView videoView =
(VideoView)this.findViewById(R.id.videoView);
MediaController mc = new MediaController(this);
videoView.setMediaController(mc);
videoView.setVideoURI(Uri.parse(
"http://video.com/episode/" +
"cotton1.mp4"));
/* videoView.setVideoPath(
Environment.getExternalStoragePublicDirectory(
Environment.DIRECTORY_MOVIES) +
"/movie.mp4");
*/
videoView.requestFocus();
videoView.start();
}
}
the URL is only an example.

videoView.setOnCompletionListener(completionListener);
OnCompletionListener completionListener=new OnCompletionListener() {
public void onCompletion(MediaPlayer mp) {
mp.stop();
chapterone.this.finish();
}
};

i hope can help i found this, but i am not sure if is correct uset it
videoView.setOnCompletionListener(new MediaPlayer.OnCompletionListener(){
#Override
public void onCompletion(MediaPlayer mp){
// invoke your activity here
Intent i = new Intent(chapterone.this, videoserie.class);
startActivity(i);
}
});
