Code to make a single MediaPlayer play more than one piece of sound in android studio

Being a novice coder, trying to code an app that plays a sound on buttonclick in a fragment; successfully did it but I want to add more small pieces of sounds to play one after another. How can I add those sounds(sound2, sound3, sound4, etc) after that 'R.raw.sound1'? Please guide..
buttonPlayAudioVar.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if(mp != null) {
if(mp.isPlaying()){
mp.stop();
mp.release();
}
}
mp = MediaPlayer.create(getActivity().getApplicationContext(), R.raw.sound1);
mp.start();
mp.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
public void onCompletion(MediaPlayer mediaPlayer) {
mp.release();
mp = null;
}
});
}
});

//you can add all the songs in a array
ArrayList<String> songsArray = new ArrayList<>();
int position = 0;
buttonPlayAudioVar.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
mediaPlayer(songsArray, position);
}
});
private void mediaPlayer(ArrayList<String> songsArray) {
if (mp != null) {
if (mp.isPlaying()) {
mp.stop();
mp.release();
}
}
if (position > songsArray.size() - 1) {
return;
}
try {
mp.setDataSource(songsArray.get(position));
position++;
mp.prepareAsync();
} catch (IOException e) {
e.printStackTrace();
}
mp.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
#Override
public void onPrepared(MediaPlayer mp) {
mp.start();
}
});
mp.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
public void onCompletion(MediaPlayer mediaPlayer) {
mp.release();
mp = null;
mediaPlayer(songsArray, position);
}
});
}

media player on completion not working, not able to print the log also.
My intention is to play the next song once the current song is completed, but i am not able to check the song is completed or not.
In the logcat, it is showing the below warning
W/MediaPlayer-JNI(16888): MediaPlayer finalized without being released.
not showing any error in the logcat......
What may be the issue?
Anything wrong with the MediaPlayer.onCreate?

setOnCompletionListener Always Work after Allocating Media Resources.
remove It From OnCreate Method And
add this listener to you Method PlaySong() after Preparing You Media Player..
It May Work.
public void playSong(){
imageName = (String) playBtn.getTag();
if(imageName.equals("play")) {
playBtn.setTag("stop");
//mediaPlayer = MediaPlayer.create(this, R.raw.chalisa);
Log.d(TAG,""+songPosition);
prepareMediaPlayer(songPosition);
seekBar.setMax(mediaPlayer.getDuration());
seekUpdation();
seekBar.setEnabled(true);
playBtn.setImageResource(R.drawable.stop);
}else{
playBtn.setImageResource(R.drawable.play);
playBtn.setTag("play");
mediaPlayer.pause();
mediaPlayer = null;
seekBar.setProgress(0);
seekBar.setEnabled(false);
subView.setText("");
}
myMediaPlayer.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
#Override
public void onCompletion(MediaPlayer mp) {
// do what ever you want
}
});
}
And Also This mediaPlayer = MediaPlayer.create(this, songsName[songPosition]); add Only Single time For Selected Song After Play do not create again..
then Again Create When You Are Doing Nextsong.

android set seekbar to initial and toggle play button to pause when music finish

i am designing a mediaplayer from scratch so what i am getting stuck in is that when the song finish to play i want to set seekbar to initial value
i know this can be done with
seekBar.setProgress(0)
but this don't work with me and i want the play button to switch back to pause button and if the user play song again than the song will be played normally
here is my code of media player and hope you tell me what is the logic and how to place it
public class MusicPlayerActivity extends AppCompatActivity implements Runnable,
SeekBar.OnSeekBarChangeListener {

SeekBar seekBar;
MediaPlayer mp = null;

You are not setting the listener : seekbar.setOnSeekBarChangeListener(this)

Add seekbar.setOnSeekBarChangeListener(this); in your onCreate otherwise the onProgressChanged() does not get called.
To reset progress bar look into the following approach:
Set OnCompletionListener on your media player instance. When the media file completes playing, your can carry out the required actions in OnCompletion(MediaPlayer mp) callback function.
Adding following code snippet before mp.start() should work for you.
mp.setOnCompletionListener(new OnCompletionListener() {
#Override
public void onCompletion(MediaPlayer mp) {
seekBar.setProgress(0); // sets seekbar to initial position.
toggleViews();//implement this function to toggle your play/pause button
}
});

Android is hanging when I press button to play music in second time

I used these codes from this reference. They want to click on button to play music and then click again to stop playing. (in their comment they said it was worked for them but hanging for me)
It is work just for first time. I mean for first click the music is playing. for second click the music is stop but for third click the phone emulator show this error:
unfortunately your program has stopped.
This is my code:
public MediaPlayer mp;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Button btn=(Button) findViewById(R.id.btnRain);
//mp = MediaPlayer.create(this, R.raw.rain);
mp = MediaPlayer.create(MainActivity.this, R.raw.rain);
btn.setOnClickListener(new View.OnClickListener() {
#Override
//MediaPlayer mp = MediaPlayer.create(getApplicationContext(), R.raw.soundFileName);
// mp.start();
public void onClick(View v) {
if (mp.isPlaying()) {
mp.stop();
mp.release();
}
else {
mp.start();
}
}
});
}

In onCreate initialize mp as :
mp = new MediaPlayer();
The error is you are releasing the media player object mp, which destroys the object, call reset method instead of release.
if (mp.isPlaying())
{
mp.stop();
mp.reset();
}
else {
mp = MediaPlayer.create(LegalActivity.this, R.raw.free1);
mp.start();
}

use this below code for play and pause the music:
public MediaPlayer mp;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Button btn=(Button) findViewById(R.id.btnRain);
//mp = MediaPlayer.create(this, R.raw.rain);
mp = MediaPlayer.create(MainActivity.this, R.raw.rain);
btn.setOnClickListener(new View.OnClickListener() {
#Override
//MediaPlayer mp = MediaPlayer.create(getApplicationContext(), R.raw.soundFileName);
// mp.start();
public void onClick(View v) {
if (mp.isPlaying()) {
mp.pause();
}
else {
mp.start();
}
}
});
}

Android Media player seekbar play from stopped position

I am trying to play a song by using seek bar listener. But when I try to drag the progress bar then it is playing from beginning of the song. It need to play from that dragged position.
Here is my code:
public class MainActivity extends Activity {
private TextView prairText;
private AssetFileDescriptor descriptor;
private SeekBar seekBar;
private MediaPlayer mp = new MediaPlayer();
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
// Keep screen active
getWindow().addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);
findViewById(R.id.play_button).setVisibility(View.INVISIBLE);
findViewById(R.id.pauseButton).setVisibility(View.VISIBLE);
init();
// Play prayer
/*if (mp != null) {
mp.start();
}*/
seekBar.setOnSeekBarChangeListener(new OnSeekBarChangeListener() {
#Override
public void onStopTrackingTouch(SeekBar seekBar) {
}
#Override
public void onStartTrackingTouch(SeekBar seekBar) {
}
#Override
public void onProgressChanged(SeekBar seekBar, int progress, boolean fromUser) {
if (mp != null && fromUser) {
mp.seekTo(progress * 1000);
}
}
});
findViewById(R.id.play_button).setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
if (mp != null) {
mp.start();
final Handler mHandler = new Handler();
//Make sure you update Seekbar on UI thread
MainActivity.this.runOnUiThread(new Runnable() {
#Override
public void run() {
if(mp != null){
int mCurrentPosition = mp.getCurrentPosition() / 1000;
seekBar.setProgress(mCurrentPosition);
}
mHandler.postDelayed(this, 1000);
}
});
findViewById(R.id.play_button).setVisibility(View.INVISIBLE);
findViewById(R.id.pauseButton).setVisibility(View.VISIBLE);
}
}
});
findViewById(R.id.pauseButton).setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
if (mp != null) {
mp.pause();
findViewById(R.id.pauseButton).setVisibility(View.INVISIBLE);
findViewById(R.id.play_button).setVisibility(View.VISIBLE);
}
mp.pause();
}
});
findViewById(R.id.restart_button).setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
if (mp != null) {
mp.seekTo(0);
mp.start();
findViewById(R.id.play_button).setVisibility(View.INVISIBLE);
findViewById(R.id.pauseButton).setVisibility(View.VISIBLE);
}
}
});
private void init() {
prairText = (TextView) findViewById(R.id.prairText);
seekBar = (SeekBar) findViewById(R.id.seekBar1);
try {
descriptor = getAssets().openFd("mysong.mp3");
mp.setDataSource(descriptor.getFileDescriptor(), descriptor.getStartOffset(), descriptor.getLength());
descriptor.close();
mp.prepare();
} catch (Exception e) {
e.printStackTrace();
}
seekBar.setMax(mp.getDuration());
}
How to resolve this issue. Thanks in advance..

Here I did tricks:
Moved MediaPlayer instance to init() method
Changed this line
int mCurrentPosition = mMediaPlayer.getCurrentPosition() / 1000;
to:
int mCurrentPosition = mp.getCurrentPosition();
Changed this line
mp.seekTo(progress * 1000);
to:
mp.seekTo(progress);
Finally working Code will be:
public class MainActivity extends Activity {
private TextView prairText;
private AssetFileDescriptor descriptor;
private SeekBar seekBar;
private MediaPlayer mp;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);

findViewById(R.id.pauseButton).setVisibility(View.VISIBLE);
init();
// Play song
if (mp != null) {
mp.start();
}
final Handler mHandler = new Handler();
//Make sure you update Seek bar on UI thread
MainActivity.this.runOnUiThread(new Runnable() {
#Override
public void run() {
if(mp != null){
int mCurrentPosition = mp.getCurrentPosition();
seekBar.setProgress(mCurrentPosition);
}
mHandler.postDelayed(this, 1000);
}
});
seekBar.setOnSeekBarChangeListener(new OnSeekBarChangeListener() {
#Override

}
}
});

}
});
findViewById(R.id.restart_button).setOnClickListener(new OnClickListener() {
#Override

if (mp != null) {
mp.seekTo(0);
mp.start();
findViewById(R.id.play_button).setVisibility(View.INVISIBLE);
findViewById(R.id.pauseButton).setVisibility(View.VISIBLE);
}
}
});

descriptor.close();
mp.prepare();
} catch (Exception e) {
e.printStackTrace();
}
int duration = mp.getDuration();
seekBar.setMax(duration);
}
}
Note: Don't forget to put mysong.mp3 in assets folder
