Mediaplayer.isPlaying always gets false

Question

I am currently working on a chat application. This has the function of sending voice notes. Sending and playing voice notes works great. But the problem is that when I play voice notes, the previous voice notes do not stop. Both are playing together.

here is my code for playing voice notes,

public static class MessageViewHolder extends RecyclerView.ViewHolder { private TextView messageTextView; private ImageView messageImageView; private TextView timeTextView; private LinearLayout textMessageLayout; private TextView messengerNameTextView; private CircleImageView messengerPhotoImageView; ImageView leftQuackImage, rightQuackImage; private LinearLayout voiceNotesLayout; private ImageView playImageView, stopImageView; private SeekBar progressSeekbar; private MediaPlayer mPlayer; double timeElapsed = 0, finalTime = 0; Handler durationHandler = new Handler(); Runnable updateSeekBarTime; boolean isPlaying; public MessageViewHolder(View itemView) { super(itemView); messageTextView = (TextView) itemView.findViewById(R.id.messageTextView); messageImageView = (ImageView) itemView.findViewById(R.id.messageImageView); timeTextView = (TextView) itemView.findViewById(R.id.timeTextView); textMessageLayout = (LinearLayout) itemView.findViewById(R.id.textMessageLayout); messengerNameTextView = (TextView) itemView.findViewById(R.id.messengerTextView); messengerPhotoImageView = (CircleImageView) itemView.findViewById(R.id.messengerImageView); leftQuackImage = (ImageView) itemView.findViewById(R.id.leftQuackImage); rightQuackImage = (ImageView) itemView.findViewById(R.id.rightQuackImage); voiceNotesLayout = (LinearLayout) itemView.findViewById(R.id.voiceNotesLayout); playImageView = (ImageView) itemView.findViewById(R.id.playImageView); stopImageView = (ImageView) itemView.findViewById(R.id.stopImageView); progressSeekbar = (SeekBar) itemView.findViewById(R.id.progressSeekbar); isPlaying = false; mPlayer = new MediaPlayer(); } public void setupAudioPlay(final long duration, final String url){ progressSeekbar.setMax((int) duration); progressSeekbar.setClickable(false); mPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC); try { mPlayer.setDataSource(url); mPlayer.prepareAsync(); } catch (IOException e) { e.printStackTrace(); }catch (IllegalStateException e){ e.printStackTrace(); } playImageView.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View view) { Log.e("Media player","isPlaying"+mPlayer.isPlaying()+isPlaying); if (mPlayer.isPlaying()) { mPlayer.stop(); mPlayer.release(); mPlayer = null; } if (!isPlaying) { isPlaying = true; mPlayer.start(); playImageView.setVisibility(View.GONE); stopImageView.setVisibility(View.VISIBLE); timeElapsed = mPlayer.getCurrentPosition(); progressSeekbar.setProgress((int) timeElapsed); durationHandler.postDelayed(updateSeekBarTime, 100); } else { isPlaying = false; mPlayer.pause(); } } }); stopImageView.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View view) { if (isPlaying) { if (stopPlaying()) { playImageView.setVisibility(View.VISIBLE); stopImageView.setVisibility(View.GONE); } } } }); mPlayer.setOnCompletionListener(new MediaPlayer.OnCompletionListener() { @Override public void onCompletion(MediaPlayer mp) { if (mp != null) { mPlayer.seekTo(0); isPlaying = false; progressSeekbar.setProgress(0); } playImageView.setVisibility(View.VISIBLE); stopImageView.setVisibility(View.GONE); } }); updateSeekBarTime = new Runnable() { public void run() { if (mPlayer != null) { if (mPlayer.isPlaying()) { timeElapsed = mPlayer.getCurrentPosition(); progressSeekbar.setProgress((int) timeElapsed); durationHandler.postDelayed(this, 100); } else { mPlayer.pause(); isPlaying = false; progressSeekbar.setProgress(0); playImageView.setVisibility(View.VISIBLE); stopImageView.setVisibility(View.GONE); } } } }; } private boolean stopPlaying() { mPlayer.pause(); mPlayer.seekTo(0); if (!mPlayer.isPlaying()) { return true; } return false; } } 

here mPlayer.isPlaying always gets false.

Please help me!

Answer 1

From the documentation :

When the pause () function call returns, the MediaPlayer object enters the Paused state. Please note that the transition from the Started state to the Paused state and vice versa occurs asynchronously in the player engine. It may take some time before the state is updated when isPlaying () is called, and this may be a few seconds in case of streaming content.

It could be here. The reasons why the sound does not stop and why isPlaying () returns true may vary. For example, multiple instances of MediaPlayer may exist in parallel, making mPlayer static preclude this possibility.

You can check the status of the audio system when necessary. In your case, whenever the play button is pressed, you must first check the condition below.

 AudioManager manager = (AudioManager)this.getSystemService(Context.AUDIO_SERVICE); if(manager.isMusicActive()) { // to do } 

To do the part, you must implement the main action, which:

 KeyEvent event = new KeyEvent(KeyEvent.ACTION_DOWN, KeyEvent.KEYCODE_MEDIA_PAUSE); audioManager.dispatchMediaKeyEvent(event); 

You can find all the documentation here.
