How can I make the music stop?

So I made a media Player that works fine but I have one big problem, after pressing play, if I close the activity or app, the music continues to play, if I click again, the music plays on the other one, and I don't know how to fix it. I just want the music to stop after closing the activity or app without any problem.
Here is the full code:
public class m1 extends AppCompatActivity {
ImageView backm1, replay, forward, btPlay, btPause;
TextView playerPosition, playerDuration;
CircularSeekBar seekBar;
MediaPlayer mediaPlayer;
Handler handler = new Handler();
Runnable runnable;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_m1);
backm1 = (ImageView) findViewById(R.id.backm1);
backm1.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
m1.super.onBackPressed();
}
});
playerPosition = findViewById(R.id.playerPosition);
playerDuration = findViewById(R.id.playerDuration);
replay = findViewById(R.id.replay);
forward = findViewById(R.id.forward);
seekBar = findViewById(R.id.seekBar);
btPause = findViewById(R.id.btPause);

mediaPlayer = MediaPlayer.create(this,R.raw.ding_dong);
runnable = new Runnable() {
#Override
public void run() {
seekBar.setProgress(mediaPlayer.getCurrentPosition());
handler.postDelayed(this,500);
}
};
int duration = mediaPlayer.getDuration();
String sDuration = convertFormat(duration);
playerDuration.setText(sDuration);
btPlay.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
btPlay.setVisibility(View.GONE);
btPause.setVisibility(View.VISIBLE);
mediaPlayer.start();
seekBar.setMax(mediaPlayer.getDuration());
handler.postDelayed(runnable, 0);
}
});
btPause.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
btPause.setVisibility(View.GONE);
btPlay.setVisibility(View.VISIBLE);
mediaPlayer.pause();
handler.removeCallbacks(runnable);
}
});
forward.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
int currentPosition = mediaPlayer.getCurrentPosition();
int duration = mediaPlayer.getDuration();
if(mediaPlayer.isPlaying() && duration != currentPosition){
currentPosition = currentPosition + 10000;
playerPosition.setText(convertFormat(currentPosition));
mediaPlayer.seekTo(currentPosition);
}
}
});
replay.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
int currentPosition = mediaPlayer.getCurrentPosition();
if (mediaPlayer.isPlaying() && currentPosition > 10000){
currentPosition = currentPosition - 10000;
playerPosition.setText(convertFormat(currentPosition));
mediaPlayer.seekTo(currentPosition);
}
}
});
seekBar.setOnSeekBarChangeListener(new CircularSeekBar.OnCircularSeekBarChangeListener() {
#Override
public void onProgressChanged(CircularSeekBar circularSeekBar, float v, boolean b) {
if (b) {
mediaPlayer.seekTo((int) v);
}
playerPosition.setText(convertFormat(mediaPlayer.getCurrentPosition()));
}
#Override
public void onStopTrackingTouch(CircularSeekBar circularSeekBar) {
}
#Override
public void onStartTrackingTouch(CircularSeekBar circularSeekBar) {
}
});
mediaPlayer.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
#Override
public void onCompletion(MediaPlayer mp) {
btPause.setVisibility((View.GONE));
btPlay.setVisibility(View.VISIBLE);
mediaPlayer.seekTo(0);
}
});
}
#SuppressLint("DefaultLocale")
private String convertFormat(int duration) {
return String.format("%02d:%02d"
,TimeUnit.MILLISECONDS.toMinutes(duration)

}
#Override
protected void onDestroy() {
super.onDestroy();
if(mediaPlayer !=null){
mediaPlayer.stop();
mediaPlayer.release();
}
}
}
I added onDestroy but I think in a wrong way and this error came out:
2021-03-08 10:13:40.843 419-4716/? E/AudioSystem: invalid attributes { Content type: AUDIO_CONTENT_TYPE_UNKNOWN Usage: AUDIO_USAGE_UNKNOWN Source: -1 Flags: 0x800 Tags: } when converting to stream

Process: com.example.diligent, PID: 28868
java.lang.IllegalStateException
at android.media.MediaPlayer.getCurrentPosition(Native Method)
I added this:
private void stopPlayer() {
if (mediaPlayer != null) {
mediaPlayer.release();
mediaPlayer = null;
Toast.makeText(this, "MediaPlayer released", Toast.LENGTH_SHORT).show();
}
}
#Override
protected void onStop() {
super.onStop();
stopPlayer();
}
And the following error:
java.lang.NullPointerException: Attempt to invoke virtual method 'int android.media.MediaPlayer.getCurrentPosition()' on a null object reference
Any other suggestions are welcome.
Thank you in advance.

Stop and release media resources on onDestroy of activity.
#Override
protected void onDestroy() {
super.onDestroy();
if(mediaPlayer !=null){
mediaPlayer.stop();
mediaPlayer.release();
}
}

MediaPlayer player; //MediaPlayer object
*Function to stop media Player *
private void stopPlayer() {
if (player != null) {
player.release();
player = null;
Toast.makeText(this, "MediaPlayer released", Toast.LENGTH_SHORT).show();
}
}
Call the function in onStop() callback
#Override
protected void onStop() {
super.onStop();
stopPlayer();
}

Here is my Recycler view adapter code
I want to post automatically data when data will add in recycler view

When you updating songNames in your adapter just match difference and post data for items which are new in the list

You need to make a method like this in your adapter.
void addItem(String songName){
datas.add(songName); // Add new Item into the data list in your Adapter.
notifyDataSetChanged();
}
And call this on the activity like this:
adapter.addItem(name);
Then, it will automatically changes.

You need separation of concerns.
Your RecyclerView and Adapter is part of your view component. It should not have any logic regarding network callbacks.
If you want to make a request when a new item is added, please check where you are adding the item to the list and calling notifyDatasetChanged(). Ideally, your app should make the network call there (or before adding the item to the list).
When you do this, the code would have the exact items that are being added so you would make an API call for that. Depending on bind method is not reliable as it gets called multiple times when user scrolls the list.

i want to reset the seekbar to start position once the music is played and button showing "play"

i want to reset the seekbar to start position once the music is played and button showing "play"...The problem with the code is that the seek bar stays at the end position after its done playing the music and button still shows "pause"...
Here's my code

MediaPlayer has got onCompletionListener(), you can use that. Your code with handlers is not too reliable, it would be better to refactor it.
mMediaPlayer.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
#Override
public void onCompletion(MediaPlayer mp) {
// do whatever you want
}
});

Why does the SeekBar not move when sound is played via MediaController (Android)?

I'm trying play an audio file with the mediacontroler in my android application. When playing audio the seekbar does not move.I looked mediacontroler function. But I could not find a function for updating seekbar.
please advice.
public class Show_subject_Activity extends Activity
implements MediaController.MediaPlayerControl, MediaPlayer.OnBufferingUpdateListener {
private RatingBar box_litner;

super.onCreate(savedInstanceState);
setContentView(R.layout.activity_show_subject);
box_litner = (RatingBar) findViewById(R.id.ratingBar1);
mController = (MediaController) findViewById(R.id.mediaController_voice);
mController.setAnchorView(null);
db_nabege.open();
cur = db_nabege.getSubject(Intent_values.id_subject);
voicefileName = getVoiceFileName();
db_nabege.close();
}
#Override
public void onResume() {
super.onResume();
mPlayer = new MediaPlayer();
// Set the audio data source
try {
mPlayer.setDataSource(this, getUriVoice());
mPlayer.prepare();
} catch (Exception e) {

}
// Set an image for the album cover

}
private Uri getUriVoice() {
File voiceFile = null;
try {

+ "audio" + File.separator + voicefileName);
} catch (Exception e) {
Log.d("log", e.toString());
}
Uri voiceUri = Uri.fromFile(voiceFile);
return voiceUri;
}
#Override

}
#Override

}
// MediaPlayerControl Methods
#Override

}
#Override

}
#Override

}
#Override

}
#Override

#Override

}
public boolean canSeekBackward() {
return true;
}
public boolean canSeekForward() {
return true;
}
#Override

}
}

You can update the seekbar yourself, e.g.:
final Handler mHandler = new Handler();
final Runnable mUpdateSeekbar = new Runnable() {
public void run() {
mSeekBar.setProgress(mMediaPlayer.getCurrentPosition());
mSeekBar.setMax(mMediaPlayer.getDuration());
mHandler.postDelayed(this, 1000);
}
};
Post the runnable in onResume and mHandler.removeCallbacks(mUpdateSeekbar) in onPause.

setOnTouchListener issue

I have added a timer to my game but by doing so i keep getting the error "The method setOnTouchListener(View.OnTouchListener) in the type View is not applicable for the arguments (scene5.MyCountDownTimer)" I can not seem to fix it. This might just be me making a simple mistake but any solutions would be great. The error is about halfway down my code, I have tagged it with //THIS IS MY PROBLEM AREA!! Cheers guys

Your problem is here:
public class scene5 extends Activity implements OnClickListener, OnTouchListener {
...
#Override
public boolean onTouch(View v, MotionEvent event) {
...
}
}
You have to implements also OnTouchListener.

Use
scene5.this
instead of this

the problem is iv.setOnTouchListener (this);
the this context you are passing belongs to the timer task, You need to use iv.setOnTouchListener (scene5.this);
Also, I think you need to find the ImageView reference in the onCreate itself. What you are doing currently ImageView iv = (ImageView) findViewById (R.id.image); won't work.
