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.

Music Player Seekbar using Android Studio

I was working in a very simple music player with a seek bar.
I could make it working but I got a problem with playing music, it doesn't work correctly every second - it backwards a while, then remain again like it's a buggy.
Here's full code:
private MediaPlayer mediaPlayer;
private Button button;
private TextView textView;
private SeekBar seek;
private Handler mHandler = new Handler();
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
button = (Button)findViewById(R.id.button);
textView = (TextView)findViewById(R.id.text);
seek = (SeekBar)findViewById(R.id.seek);
mediaPlayer = new MediaPlayer();
mediaPlayer = MediaPlayer.create(getApplicationContext(),R.raw.threedays);
MainActivity.this.runOnUiThread(new Runnable() {
#Override
public void run() {
if(mediaPlayer != null){
int mCurrentPosition = mediaPlayer.getCurrentPosition() / 1000;
seek.setProgress(mCurrentPosition);
}
mHandler.postDelayed(this, 1000);
}
});
seek.setOnSeekBarChangeListener(new SeekBar.OnSeekBarChangeListener() {
#Override
public void onProgressChanged(SeekBar seekBar, int progress, boolean fromUser) {
seekBar.setMax(mediaPlayer.getDuration() / 1000);
textView.setText(progress + "/" + seekBar.getMax());
mediaPlayer.seekTo(progress*1000);
}
#Override
public void onStartTrackingTouch(SeekBar seekBar) {
}
#Override
public void onStopTrackingTouch(SeekBar seekBar) {
}
});
mediaPlayer.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
#Override
public void onCompletion(MediaPlayer mp) {
pause();
}
});
button.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if (mediaPlayer.isPlaying()) {
pause();
} else {
start();
}
}
});
}
public void start(){
if(mediaPlayer!=null) {
mediaPlayer.start();
button.setText("Pause");
}
}
public void pause(){
if(mediaPlayer!=null) {
mediaPlayer.pause();
button.setText("Play");
}
}
#Override
protected void onDestroy() {
if(mediaPlayer!=null && mediaPlayer.isPlaying()) {
mediaPlayer.pause();
mediaPlayer.release();
mediaPlayer = null;
}
super.onDestroy();
}

Try this code on seek.setOnSeekBarChangeListener
#Override
public void onProgressChanged(SeekBar seekBar, int progress, boolean fromUser)
{
seekBar.setMax(mediaPlayer.getDuration() / 1000);
textView.setText(progress + "/" + seekBar.getMax());
if(fromUser)
{
mediaPlayer.seekTo(progress*1000);
}
}

Android custom alert dialog mediaplayer seekbar

In my alart dialog i want play mp3 from SDcard and update seekbar. its working fine with tha following code. But Seekbar Ontouchlistener not work, Like forward rewind mp3.
May maiin Activity:
public class MainActivity extends Activity {
private MediaPlayer mediaPlayer = new MediaPlayer();
SeekBar seekBarProgress;
ImageButton buttonPlayPause;
private int mediaFileLengthInMilliseconds;
private final Handler handler = new Handler();
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Button button = (Button) findViewById(R.id.button);
button.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View arg0) {
final Dialog dialog = new Dialog(MainActivity.this);
dialog.setContentView(R.layout.popup_ringtones);
dialog.setTitle("Title...");
buttonPlayPause = (ImageButton) dialog.findViewById(R.id.play);
seekBarProgress = (SeekBar) dialog.findViewById(R.id.SeekBarTestPlay);
seekBarProgress.setProgress(0);
seekBarProgress.setMax(100);
dialog.setOnDismissListener(new DialogInterface.OnDismissListener() {
#Override
public void onDismiss(DialogInterface dialog) {
mediaPlayer.pause();
}
});
buttonPlayPause.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
try {
if (mediaPlayer.isPlaying()) {
mediaPlayer.stop();
mediaPlayer.release();
mediaPlayer = new MediaPlayer();
}
AssetFileDescriptor descriptor = getAssets().openFd("a.mp3");
mediaPlayer.setDataSource(descriptor.getFileDescriptor(), descriptor.getStartOffset(), descriptor.getLength());
descriptor.close();
mediaPlayer.prepare();
mediaPlayer.setVolume(1f, 1f);
mediaPlayer.setLooping(true);
mediaPlayer.start();
primarySeekBarProgressUpdater();
} catch (Exception e) {
e.printStackTrace();
}
mediaFileLengthInMilliseconds = mediaPlayer.getDuration();
}
});
dialog.show();
}
});
}
private void primarySeekBarProgressUpdater() {
seekBarProgress.setProgress((int)(((float)mediaPlayer.getCurrentPosition()/mediaFileLengthInMilliseconds)*100)); // This math construction give a percentage of "was playing"/"song length"
if (mediaPlayer.isPlaying()) {
Runnable notification = new Runnable() {
public void run() {
primarySeekBarProgressUpdater();
}
};
handler.postDelayed(notification,1000);
}
}
}
I want ontouch seekbar update song, How can i implement?

You have to implement setOnSeekBarChangeListener on your seekbar like this
playerSeekbar.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 (fromUser) {
mMediaPlayer.seekTo(progress);
updateTime();
}
}
});

sound doesn't stop when the user press back key

I'm newbie in android programming. I have the following code with a mediaplayer. when the user presses the back key or goes to another activity the sound won't stop.
what's the problem? I have the onDestory method but my problem exists!
public class Elementary1Activity extends Activity implements Runnable, OnClickListener, OnSeekBarChangeListener{
private SeekBar seekBar;
private ImageButton startMedia;
private ImageButton pauseMedia;
private MediaPlayer mp;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.elementary1);
AudioControl();
}
public void AudioControl(){
seekBar = (SeekBar) findViewById(R.id.seekBarnew2);
startMedia = (ImageButton) findViewById(R.id.playbuttonnew2);
pauseMedia = (ImageButton) findViewById(R.id.pausebuttonnew2);
seekBar.setOnSeekBarChangeListener(this);
startMedia.setOnClickListener(this);
pauseMedia.setOnClickListener(this);
}
public void run() {
int currentPosition= 0;
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) {
pauseMedia.setVisibility(View.VISIBLE);
seekBar.setVisibility(View.VISIBLE);
startMedia.setVisibility(View.INVISIBLE);
if (v.equals(startMedia)) {
if (mp != null && mp.isPlaying()) return;
if(seekBar.getProgress() > 0) {
mp.start();
return;
}
mp = MediaPlayer.create(Elementary1Activity.this, R.raw.e1);
mp.start();
seekBar.setProgress(0);
seekBar.setMax(mp.getDuration());
new Thread(this).start();
}
if (v.equals(pauseMedia) && mp!=null) {
mp.pause();
pauseMedia.setVisibility(View.INVISIBLE);
startMedia.setVisibility(View.VISIBLE);
}
}
#Override
public void onDestroy() {
super.onStop();
mp= MediaPlayer.create(Elementary1Activity.this,R.raw.e1);
if(mp.isPlaying())
{
mp.stop();
mp.release();
finish();
}
}
public void onStartTrackingTouch(SeekBar seekBar) {
}
public void onStopTrackingTouch(SeekBar seekBar) {
}
public void onProgressChanged(SeekBar seekBar, int progress,
boolean fromUser) {
if(fromUser) mp.seekTo(progress);
}
}

I'd use onPause() event in your Elementary1Activity to manage the music pausing.
Something like:
#Override
public void onPause() {
super.onPause();
if (mp!=null) {
mp.pause();
}
}

You can do two things. If you want that MediaPlayer stop when you push back button and you want to close the app the best option is:
#Override
public void onDestroy(){
if(mp != null){
if(mp.isPlaying()){
mp.stop
}
mp.release();
}
super.onDestroy();
}
And if you want to make that MediaPlayer stop when you change of activity:
#Override
public void onPause(){
if (mp != null && mp.isPlaying()){
mp.pause();
}
}
Apart of that, don't create a new MediaPlayer when you want to close your app.

SeekBar with android 2.3.3 Mediaplayer! How can i add seekbar in my project?

I want to add a SeekBar to control my mediaplayer process, but i do not know how to add code.Please help me, and give some example in my project code!
package lamTo.OSDC_Project;
public class OSDC_Mini_ProjectActivity extends Activity implements MediaPlayer.OnCompletionListener {
private ImageButton play,pause,stop;
private MediaPlayer mp;
private SeekBar seekbar;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
play = (ImageButton)findViewById(R.id.play);
pause = (ImageButton)findViewById(R.id.pause);
stop = (ImageButton)findViewById(R.id.stop);
play.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) {
play();
}
});
pause.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) {
pause();
}
});
stop.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) {
stop();
}
});
setup();
}
#Override
public void onDestroy() {
super.onDestroy();
if (stop.isEnabled()) {
mp.stop();
}
}
public void onCompletion(MediaPlayer mp) {
stop();
}
private void play() {
mp.start();
play.setEnabled(false);
pause.setEnabled(true);
stop.setEnabled(true);
}
private void stop() {
mp.stop();
pause.setEnabled(false);
stop.setEnabled(false);
try {
mp.prepare();
mp.seekTo(0);
play.setEnabled(true);
}
catch (Throwable t) {
error(t);
}
}
private void pause() {
mp.pause();
play.setEnabled(true);
pause.setEnabled(false);
stop.setEnabled(true);
}
private void loadClip() {
try {
mp=MediaPlayer.create(this, R.raw.bigbang);
mp.setOnCompletionListener(this);
}
catch (Throwable t) {
error(t);
}
}
private void setup() {
loadClip();
play.setEnabled(true);
pause.setEnabled(false);
stop.setEnabled(false);
}
private void error(Throwable t) {
AlertDialog.Builder builder=new AlertDialog.Builder(this);
builder
.setTitle("Error!")
.setMessage(t.toString())
.setPositiveButton("Yes", null)
.show();
}
}

In your design layout, add this
<SeekBar
android:id="#+id/SeekBar01"
android:layout_height="wrap_content"
android:layout_width="fill_parent"
/>
In your onCreate() add this
seekBar = (SeekBar) findViewById(R.id.SeekBar01);
seekBar.setMax(mPlayer.getDuration());
seekBar.setOnSeekBarChangeListener(new OnSeekBarChangeListener() {
public void onStopTrackingTouch(SeekBar seekBar) {
// TODO Auto-generated method stub
}
public void onStartTrackingTouch(SeekBar seekBar) {
// TODO Auto-generated method stub
}
public void onProgressChanged(SeekBar seekBar, int progress,
boolean fromUser) {
seekChange(seekBar, progress, fromUser);
}
});
}
// This makes the seekbar follow the music
public void startPlayProgressUpdater() {
seekBar.setProgress(mPlayer.getCurrentPosition());
if (mPlayer.isPlaying()) {
Runnable notification = new Runnable() {
public void run() {
startPlayProgressUpdater();
}
};
handler.postDelayed(notification,1000);
}else{
mPlayer.pause();
buttonPlayStop.setText(getString(R.string.play_str));
seekBar.setProgress(0);
}
}
// This is event handler thumb moving event
private void seekChange(SeekBar seekBar, int progress,
boolean fromUser){
mPlayer.seekTo(progress);
}
