How to play and pause audio in firebase recyclerview in android

I am developing an app in which I have to fetch audio from firebase. I am using firebase recycler view. I am getting a problem that when I click the first song it plays good, but when I click second item then the first song's play button does not change and seekbar of first and second song changes.
Here is the code.
holder.play_btn.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
String audioUrl3 = model.getMedia();
if (!isPlaying){
if (mPlayer!=null){
mPlayer.release();
}
Toast.makeText(mContext, "Loading....", Toast.LENGTH_SHORT).show();
isPlaying = true;
Uri uri = Uri.parse(audioUrl3);
mPlayer = new MediaPlayer();
mPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
mPlayer.reset();
try {
mPlayer.setDataSource(mContext,uri);
} catch (Exception e) {
e.printStackTrace();
Toast.makeText(mContext, "Error Occured", Toast.LENGTH_SHORT).show();
}
try{
mPlayer.prepareAsync();
}catch (Exception e){
Toast.makeText(mContext, "Error Occured", Toast.LENGTH_SHORT).show();
holder.play_btn.setImageDrawable(holder.play_btn.getContext().getResources().getDrawable(R.drawable.ic_play));
}
mPlayer.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
#Override
public void onPrepared(MediaPlayer mp) {
if(mPlayer.isPlaying()){
mPlayer.stop();
}
mPlayer.start();
holder.play_btn.setImageDrawable(holder.play_btn.getContext().getResources().getDrawable(R.drawable.ic_pause));
holder.seekBar.setMax(mPlayer.getDuration());
Toast.makeText(mContext, "Playing...", Toast.LENGTH_SHORT).show();
updateSeekBar(holder.seekBar);
}
});
mPlayer.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
#Override
public void onCompletion(MediaPlayer mp) {
holder.play_btn.setImageDrawable(holder.play_btn.getContext().getResources().getDrawable(R.drawable.ic_play));
isPlaying = false;
}
});
}
else {
isPlaying=false;
stopPlaying();
}
}
private void stopPlaying() {
mPlayer.release();
mPlayer=null;
holder.play_btn.setImageDrawable(holder.play_btn.getContext().getResources().getDrawable(R.drawable.ic_play));
}
});
}
private void updateSeekBar(final SeekBar seek) {
try{
int pos = mPlayer.getCurrentPosition();
seek.setProgress(pos);
}catch (Exception e){
}
runnable = new Runnable() {
#Override
public void run() {
updateSeekBar(seek);
}
};
handler.postDelayed(runnable, 1800);
}

Play audio from url one after other

I want to play/stream audio from url one after other automatically.
here what I have tried:
final String audioUrl[] = {"https://www.googleapis.com/storage/v1/b/ezconnectpoc/o/NV.wav?alt=media", "https://www.googleapis.com/storage/v1/b/ezconnectpoc/o/cqo.wav?alt=media"};
backtobackButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
try {
mediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
mediaPlayer.setDataSource(audioUrl[currentTrack]);
mediaPlayer.prepareAsync();
mediaPlayer.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
#Override
public void onPrepared(MediaPlayer mp) {
mediaPlayer.start();
}
});
mediaPlayer.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
#Override
public void onCompletion(MediaPlayer mp) {
try {
Log.d("Current track",currentTrack+"");
Log.d("audioUrl.length",audioUrl.length+"");
if (currentTrack < audioUrl.length) {
currentTrack++;
mediaPlayer.setDataSource(audioUrl[currentTrack]);
mediaPlayer.setOnCompletionListener(this);
mediaPlayer.start();
}
mediaPlayer.stop();
} catch (Exception e) {
e.printStackTrace();
}
}
});
} catch (Exception e) {
e.printStackTrace();
// make something
}
}
});
My first audio url gets played when I click on backtoback named button but failed to play second audio from url.

changed this part of code
mediaPlayer.reset();
mediaPlayer.setDataSource(audioUrl[currentTrack]);
mediaPlayer.prepareAsync();
mediaPlayer.setOnCompletionListener(this);
mediaPlayer.start();
currentTrack++;
and worked.

adding mutiple audio file in android

i'm adding multiple audio files using
try {
MediaPlayer mp = MediaPlayer.create(context, R.raw.play);
audioArr[0] = mp;
mp.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
#Override
public void onPrepared(MediaPlayer mp) {
mp.start();
}
});
mp.prepare();
} catch (Exception e) {
e.printStackTrace();
}
and releasing media in a function as
for (MediaPlayer media : audioList) {

if(media.isPlaying())
media.stop();
media.release();
media = null;
}
}
stil i'm not able to play multiple audio file in my application,first time playing with audio,so kindly guide

Try this :
void addSongs()
{
File songs = new File(sdPath); //sdPath is the path of your audio files
if(songs.listFiles(new SongFilter()).length > 0)
{
for(File file : songs.listFiles(new SongFilter()))
{
vector.add(file.getName());
}
arrayAdapter.setNotifyOnChange(true); //arrayAdapter Array Adapter
songList.setAdapter(arrayAdapter); //songList is a ListView
}
}
SongFilter Class like this :
class SongFilter implements FilenameFilter
{
public boolean accept(File dir, String filename)
{
return (filename.endsWith(".mp3"));
}
}

buttonSound.setOnCompletionListener(new OnCompletionListener() {
#Override
public void onCompletion(MediaPlayer mp) {
// play another sound here.do your stuff whatever you want to do
mp.stop();
}
});

public class AudioActivity extends Activity implements MediaPlayer.OnCompletionListener {
int [] songs;
MediaPlayer mediaPlayer;
int current_index = 0;
#Override
protected void onCreate(Bundle savedInstanceState) {##}
private void start(){
songs= new int[] {R.raw.s1,R.raw.s2,R.raw.s3,R.raw.s4};
mediaPlayer = MediaPlayer.create(this, songs[0]);
mediaPlayer.setOnCompletionListener(this);
mediaPlayer.start();
}
#Override
public void onCompletion(MediaPlayer mp) {
**// This is the completion listener registered with mediaplayer instance.**
playNextSong();
}
private void playNextSong()
{
current_index = (current_index +1)% songs.length;
AssetFileDescriptor afd = this.getResources().openRawResourceFd(songs[current_index]);
if(current_index!=0){
try
{
mediaPlayer.reset();
mediaPlayer.setDataSource(afd.getFileDescriptor(), afd.getStartOffset(), afd.getDeclaredLength());
mediaPlayer.prepare();
mediaPlayer.start();
afd.close();
}
catch (IllegalArgumentException e){}
catch (IllegalStateException e){}
catch (IOException e){}
}else{
mediaPlayer.stop();
}
}
}
