Automatic next song makes seekbar and buttons crash - java

I'm new to Android programming. I followed a mediaplayer tutorial but I'm now trying to make it more advance, the only problem is thats not working as expected.
When the song is finished it should start playing the next song, but doesn't update my seekbar (only updates Max) and it makes my buttons crash my app. I tried many things but can't fix it myself. If i press the next button however (before music track ends) the buttons and seekbar work.
What I'm want is my seekbar to reset for the new song and go again, and i want my buttons to work after the onCompletion next song.
Here my code:
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_player);
btPlay = (ImageButton) findViewById(R.id.btPlay);
btNxt = (ImageButton) findViewById(R.id.btNxt);
btPv = (ImageButton) findViewById(R.id.btPv);
btPlay.setOnClickListener(this);
btNxt.setOnClickListener(this);
btPv.setOnClickListener(this);
sb = (SeekBar) findViewById(R.id.seekBar);
updateSeekBar = new Thread() {
#Override
public void run() {
int TotalDuration = mp.getDuration();
int currentPosition = 0;
while (currentPosition < TotalDuration) try {
sleep(500);
currentPosition = mp.getCurrentPosition();
sb.setProgress(currentPosition);
} catch (InterruptedException e) {
e.printStackTrace();
}
}
};
if (mp != null) {
mp.stop();
mp.release();
}
Intent i = getIntent();
Bundle b = i.getExtras();
mySongs = (ArrayList) b.getParcelableArrayList("songlist");
position = b.getInt("pos", 0);
u = Uri.parse(mySongs.get(position).toString());
mp = MediaPlayer.create(getApplicationContext(), u);
mp.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
#Override
public void onCompletion(MediaPlayer mp) {
try {
mp.stop();
mp.reset();
position = (position + 1) % mySongs.size();
u = Uri.parse(mySongs.get(position).toString());
mp = MediaPlayer.create(getApplicationContext(), u);
sb.setMax(mp.getDuration());
mp.start();
} catch (Exception e) {
e.printStackTrace();
}
}
});
mp.start();

}
});

For part one, implement an setOnCompletionListener as already answered here: Android Media player play the song x times
For repeating for for 1 hour, change the counter with the timer implementation:
// get current time in milliseconds + 1 hour
long tRef = System.currentTimeMillis() + 1 * 60 * 60 * 1000L;
// set listener
mp.setOnCompletionListener(new OnCompletionListener(){
#Override
public void onCompletion(MediaPlayer mediaPlayer) {
// current time
long tNow = System.currentTimeMillis();
if (tNow < tEnd) {
mediaPlayer.seekTo(0);
mediaPlayer.start();
}
}});
To trigger the looping again, you just need to set the tRef to a new value.
Side note: If you need both functionalities at the same time, then combine them into one listener as you cannot have two listeners on the same media player at the same time.
Alternative solution would be to set mp.setLooping() and make a timer task to turn it off, but I would not recommend it here, as it might require some lifecycle management.
Timer timerObj = new Timer();
TimerTask timerTaskObj = new TimerTask() {
public void run() {
if (mp != null) {
mp.setLooping(false)
}
}
};
timer.schedule(timerTaskObj, 0, 1 * 60 * 60 * 1000L);

android recyclerview viewholder Mediaplayer handling taps problem

I am playing audio files(MP3) by clicking on Item view, and the previous file stop automatically but the problem is that after tapping 3rd item of recyclerview the 1st one does not play sound on its click and the same problem happened on some other clicks of the list. I have added full Adapter class
public class RingToneAdapter extends RecyclerView.Adapter<RingToneAdapter.RingToneViewHolder> {
//removed declared varaible for the sake of post to edit
static final int[] resID = {R.raw.a48, R.raw.funny_hen};
public RingToneAdapter(Context rcntx, List<RingTone_Items> ringtonelist) {
this.rcntx = rcntx;
this.ringtonelist = ringtonelist;
}
#NonNull
#Override
public RingToneViewHolder onCreateViewHolder(#NonNull ViewGroup viewGroup, int i) {
view = LayoutInflater.from(rcntx).inflate(R.layout.ringtone_values, viewGroup, false);
RingToneViewHolder ringToneViewHolder = new RingToneViewHolder(view);
return ringToneViewHolder;
}
//playing sounds on recycler view
#Override
public void onBindViewHolder(#NonNull final RingToneViewHolder ringToneViewHolder, final int i) {
final RingTone_Items ringTone_items = ringtonelist.get(i);
ringToneViewHolder.rtv.setText(ringTone_items.getRintonetv());
if (mSelectedItem == i) {
ringToneViewHolder.iconplay.setImageResource(R.drawable.ic_pause_black_24dp);
} else {
ringToneViewHolder.iconplay.setImageResource(R.drawable.ic_play_arrow_black_24dp);
}
ringToneViewHolder.itemView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if (mp != null && mp.isPlaying()) {
mp.stop();
mp.reset();
mp = null;
ringToneViewHolder.iconplay.setImageResource(R.drawable.ic_play_arrow_black_24dp);
}
//Intent it = new Intent(rcntx, ViewPager_Data.class);
Intent it = new Intent(rcntx, AndroidViewPagerExample.class);
it.putExtra("POS",i);
it.putExtra("name",ringTone_items.getRintonetv());
rcntx.startActivity(it);
}
});
ringToneViewHolder.iconplay.setOnClickListener(new View.OnClickListener() {
#Override

if (mSelectedItem == i) {
mSelectedItem = -1;
oldpossssssss = i;
} else {
mSelectedItem = i;
}
notifyDataSetChanged();
if (mp != null && mp.isPlaying()) {
mp.stop();
mp.reset();
mp = null;
if (oldpossssssss == i) {
} else {
mp = new MediaPlayer();
mp = MediaPlayer.create(rcntx, resID[i]);
mp.start();
}
} else {
mp = new MediaPlayer();
mp = MediaPlayer.create(rcntx, resID[i]);
mp.start();
}
}
});
}
#Override
public int getItemCount() {
return ringtonelist.size();
}
class RingToneViewHolder extends RecyclerView.ViewHolder {
private TextView rtv, hello, close;
private ImageView iconplay;
public RingToneViewHolder(#NonNull View itemView) {
super(itemView);
rtv = itemView.findViewById(R.id.ringtitle);
iconplay = itemView.findViewById(R.id.playicon);
}
}
How can I manage this smoothly according to click the play media file accordingly. Where is I am doing wrong please help me Thanks.
I would suggest you to use singletone media player in your viewHolders. Firstly, using multiple prepared mediaPlayers are not very memory efficient. Secondly, it will allow you to resolve problems with played sound on the background because one mediaPlayer will play only one audio at a time.
ringToneViewHolder.itemView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if (mp != null && mp.isPlaying()) {
mp.stop();
mp.reset();
mp.release();
mp = null;
ringToneViewHolder.iconplay.setImageResource(R.drawable.ic_play_arrow_black_24dp);
}
//Intent it = new Intent(rcntx, ViewPager_Data.class);
Intent it = new Intent(rcntx, AndroidViewPagerExample.class);
it.putExtra("POS",i);
it.putExtra("name",ringTone_items.getRintonetv());
rcntx.startActivity(it);
}
});
ringToneViewHolder.iconplay.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if (mSelectedItem == i) {
oldpossssssss = i;
} else {
mSelectedItem = i;
}
notifyDataSetChanged();
if (oldpossssssss == i) {
if(mp != null){
if(mp.mp.isPlaying()){
mp.pause();
} else{
mp.start();
}
}
} else {
createMediaPlayer(i)
}
}
});
Use this method when you create MediaPlayer
private void createMediaPlayer(int i)
{
if (mp!=null)
{
if(mp.isPlaying())
{
mp.stop();
mp.reset();
mp.release();
mp=null;
}
}
mp = new MediaPlayer();
mp = MediaPlayer.create(rcntx, resID[i]);
mp.start();
}
May be its work.

Mediaplayer action buttons next,previous, repeat and shuffle

For some reason, the repeat and shuffle buttons are not doing anything.
The buttons previous and next work perfectly.
In my app I am communicating with my service through broadcasts.
mediaPlayer is a public static in my service class and I am importing it in other activity.
public static MediaPlayer mediaPlayer = new MediaPlayer(); (In Service.class)
Activity
This is the code for the buttons
if (mediaPlayer != null) {
if (mediaPlayer.isPlaying()) {
mBtnPlayPause.setImageResource(R.drawable.ic_action_pause_white);
tvSongListSize.setText((songIndex + 1) + "/" + songList.size());
updateProgressBar();

mBtnShuffle.setImageResource(R.drawable.ic_shuffle_on);
isRepeat = false;

}
}
});
mBtnPlayPause.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
try {
if (mediaPlayer != null) {

mediaPlayer.pause();
mBtnPlayPause.setImageResource(R.drawable.ic_action_play);
} else {
mediaPlayer.start();
mBtnPlayPause.setImageResource(R.drawable.ic_action_pause_white);

nextSong();
}
});
mBtnPrev.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {

}
});
Code in onCompletionListener
#Override
public void onCompletion(MediaPlayer mp) {
if (isRepeat){
//Store current songIndex in mSharedPreferences
StorageUtil storageUtil = new StorageUtil(getContext());
storageUtil.storeSongIndex(songIndex);
//Send media with BroadcastReceiver

tvSongListSize.setText((songIndex + 1) + "/" + songList.size());
//Store random songIndex in mSharedPreferences

//Send media with BroadcastReceiver

activeSong = songList.get(songIndex);
}else{
stopSelf();
}
stopSong();
mediaPlayer.reset();
if (mMediaSessionManager == null) {
try {
initMediaSession();
initMediaPlayer();
} catch (RemoteException e) {
e.printStackTrace();
stopSelf();
}
}
initMediaPlayer();
updateMetaData();
NotificationBuilder(PlaybackStatus.PLAYING);
}
};
The buttons mBtnShuffle and mBtnRepeat do not trigger onCompletion. They are just 2 ordinary buttons that you use to set the flags isShuffle and isRepeat.
onCompletion is triggered when a song has been completed.
So if you want something to happen when the 2 buttons are tapped you should put some code in their listeners.

progress bar for music player doesnt work and crashes

this is my code, i am almost certain the problem is with the while loop.
public void start(View view) {
int currentPosition = 0;
player = MediaPlayer.create(this, R.raw.sound);
player.start();
int total = player.getDuration();
progressBar.setProgress(0);
progressBar.setMax(player.getDuration());
while (player != null && currentPosition < total) {
// try {
// Thread.sleep(500);
currentPosition = player.getCurrentPosition();
// } catch (InterruptedException e) {
// return;
// } catch (Exception e) {
// return;
// }
progressBar.setProgress(currentPosition);
}
}
public void stop(View view) {
player.stop();
}
whether or not i have the sleep intervals my result is the same; the sound starts playing but i cant stop it, and the progress bar doesn't move.
i would appreciate some help
I used this code in my app for using seekBar with MediaPlayer. It implements Runnable to keep the seekBar updating as the music plays. Take a look at the code:

seekBar = (SeekBar) findViewById(R.id.seekBar1);
startMedia = (Button) findViewById(R.id.button1);
stopMedia = (Button) findViewById(R.id.button2);
startMedia.setOnClickListener(this);
stopMedia.setOnClickListener(this);
seekBar.setOnSeekBarChangeListener(this);
seekBar.setEnabled(false);
}
public void run() {
int currentPosition = mp.getCurrentPosition();
int total = mp.getDuration();
while (mp != null && currentPosition < total) {
try {
Thread.sleep(1000);
currentPosition = mp.getCurrentPosition();
} catch (InterruptedException e) {
return;
} catch (Exception e) {
return;
}
seekBar.setProgress(currentPosition);
}
}
public void onClick(View v) {
if (v.equals(startMedia)) {
if (mp == null) {
mp = MediaPlayer.create(getApplicationContext(), R.raw.song2);
seekBar.setEnabled(true);
}
if (mp.isPlaying()) {
mp.pause();
startMedia.setText("play");
} else {
mp.start();
startMedia.setText("pause");
seekBar.setMax(mp.getDuration());
new Thread(this).start();
}
}
if (v.equals(stopMedia) && mp != null) {
if (mp.isPlaying() || mp.getDuration() > 0) {
mp.stop();
mp = null;
startMedia.setText("play");
seekBar.setProgress(0);
}
}
}
public void onProgressChanged(SeekBar seekBar, int progress,
boolean fromUser) {
try {
if (mp.isPlaying() || mp != null) {
if (fromUser)
mp.seekTo(progress);
} else if (mp == null) {
Toast.makeText(getApplicationContext(), "Media is not running",
Toast.LENGTH_SHORT).show();
seekBar.setProgress(0);
}
} catch (Exception e) {

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

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
}
});
