Repeat sound every time a button is pushed - android

I'm testing Android sound implementation. I have an "imagenButton" and when I push it, a method "musica()" is called. Is really simple:
public void musica(View v) {
img = (ImageView) findViewById(R.id.Migrunido);
if(m.isPlaying()) {
m.stop();
}
else {
m.start();
}
}
It works, but want when I press the button, the sound repeats. I was reading a lot about threads and I have to prepare it before "stop()" but can't fix it.
I have to prepare my method? Or what is the problem?
Thanks


try
public static void playAudio(int id) {
mediaPlayer = MediaPlayer.create(context,id);
if (!mediaPlayer.isPlaying()) {
mediaPlayer.start();
mediaPlayer.setOnCompletionListener(new OnCompletionListener() {
#Override
public void onCompletion(MediaPlayer mp) {
mp.stop();
mp.release();
}
});
}else{
mediaPlayer.stop();
mediaPlayer.release();
}
}
if this doesn't work try mediaPlayer.prepare(); before you start.

Android Media player onClick issue

I'm using MediaPlayer for playing sounds onClick. Until the sound is finished the click event is not play the sound again. How can it play the sound again on click, when the sound is currently playing?
final MediaPlayer mistake = MediaPlayer.create(getActivity(), R.raw.mistake);
tv_mistake.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
mistake.start();
}
});

You must create a new MediaPlayer object to play the sound again like so.
tv_mistake.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if (mistake != null) {
mistake.release();
mistake = MediaPlayer.create(getActivity(), R.raw.mistake);
}
mistake.start();
}
});
You can read more about MediaPlayer in the following links.
Also a quite similar question
MediaPlayer, MediaPlayer Tutorial, MediaPlayer Tutorial From Google

Most of the errors in MediaPlayer comes due to improper handling of different states of its object.
You should release MediaPlayer object after completing playback or before calling start() again.
It is also recommended that once a MediaPlayer object is no longer being used, call release() immediately so that resources used by the internal player engine associated with the MediaPlayer object can be released immediately.
Create a MediaPlayer object as:
Mediaplayer mediaPlayer = null;
And call playMistakeSound() on button click:
tv_mistake.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
playMistakeSound()
}
});
Implement playMistakeSound() as:
void playMistakeSound() {
try {
// releases MediaPlayer object before calling create() again while previous is still playing
if (mediaPlayer != null){
mediaPlayer.reset();
mediaPlayer.release();
mediaPlayer = null;
}
mediaPlayer = MediaPlayer.create(getActivity() /*Context*/, R.raw.mistake);
// this will release MediaPlayer as soon as it completes
mediaPlayer.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
#Override
public void onCompletion(MediaPlayer mp) {
if (mp != null) {
mp.reset();
mp.release();
mediaPlayer = null;
}
}
});
mediaPlayer.start();
} catch (Exception e) {
// log exception and handle
e.printStackTrace();
}
}

Stopping media player before playing next audio

I am having a listview in my app. Each listview item has button which will play an audio from a url received from web service. But my problem is that if I click play button from the next item then both start playing together. I am having problem in this. I want only one to play at a time. Right now I am creating new Media player object everytime button is clicked, but I also tried creating a single global object but in this case it only plays first time and not after it. What is the possible solution of it.
finalHolder.iv_sound.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
try {
MediaPlayer mp = new MediaPlayer();
mp.setDataSource(birdsUrlList.get(position).getUrl_audio());
mp.prepare();
mp.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
#Override
public void onPrepared(MediaPlayer mp) {
mp.start();
}
});
mp.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
#Override
public void onCompletion(MediaPlayer mp) {
mp.release();
}
});
//startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse(birdsUrlList.get(position).getUrl_video())));
} catch (Exception e) {
e.printStackTrace();
}
}
});

Make the mp variable global and remove this:
mp.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
#Override
public void onCompletion(MediaPlayer mp) {
mp.release();
}
});
because if you take a look at this reference http://developer.android.com/reference/android/media/MediaPlayer.html#StateDiagram it says:
Once the MediaPlayer object is in the End state, it can no longer be
used and there is no way to bring it back to any other state.
And when you call mp.release(); the media player WILL go to that state.
Then make your onClickListener look something like this:
#Override
public void onClick(View v) {
try {
if (mp.isPlaying()) {
mp.stop();
mp.reset();
}
mp.setDataSource(birdsUrlList.get(position).getUrl_audio());
//... and so on
mp.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
#Override
public void onCompletion(MediaPlayer mp) {
mp.stop();
mp.reset();
}
});
The trick there is to make it back to Idle state so you can set the new data source and start playing again. It's all about the states...

setNextMediaPlayer not working

I am trying to find out how to use the android's MediaPlayer method setNextMediaPlayer which should smoothly transition from one player (song) to another. But do not know how to use the method since there is a lack of documentation.
This is what i do and it does not work:
final MediaPlayer mp1 = new MediaPlayer();
final MediaPlayer mp2 = new MediaPlayer();
try {
mp1.setDataSource("http://song1.MP3");
mp2.setDataSource("http://song2.mp3");
mp1.prepareAsync();
mp1.setOnPreparedListener(new OnPreparedListener() {
#Override
public void onPrepared(MediaPlayer mp) {
mp1.start();
}
});
mp1.setNextMediaPlayer(mp2);
mp1.setOnCompletionListener(new OnCompletionListener() {
#Override
public void onCompletion(MediaPlayer mp) {
mp2.prepareAsync();
mp2.setOnPreparedListener(new OnPreparedListener() {
#Override
public void onPrepared(MediaPlayer mp) {
mp2.start();
}
});
}
});
} catch (IllegalArgumentException e) {}
So the first song plays. But after it finishes the second does not start.

Got it to work.
mp1.setDataSource(song1);
mp1.prepareAsync();
mp1.setOnPreparedListener(new OnPreparedListener() {
#Override
public void onPrepared(MediaPlayer mp) {
mp1.start();
}
});
//mp1.start();
//mp1.seekTo(1000*100);
mp2.setDataSource(song2);
mp2.prepare();
mp1.setNextMediaPlayer(mp2);
The only problem is that the second mediaplayer cannot be called as async (i.e. mp2.prepareAsync()). I do not know why, but if you try it like that it does not start, which is a bad thing :/.

MediaPlayer setNextMediaPlayer gives a lot of problem what i do is this:
in the onCompletion() reset() the mediaplayer, setDataSource() and prepareAsync().
Something like this
mp1.setDataSource("http://song1.MP3");
mp1.prepareAsync();
mp1.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
#Override
public void onPrepared(MediaPlayer mp) {
mp1.start();
}
});
mp1.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
#Override
public void onCompletion(MediaPlayer mp) {
mp1.reset();
//ADD FLAG FOR STOP
try {
mp1.setDataSource("http://song2.mp3");
} catch (IOException e) {
e.printStackTrace();
}
mp1.prepareAsync();
}
});
Then in the onCompletion you need some flag to check if the last song was played to stop, because the code as i posted will loop in the last song.

Android button click to play music, click again to stop sound

I have a button, when I click it plays music, how to do it, when I click second time, to stop the music?
Button two = (Button)this.findViewById(R.id.button2);
final MediaPlayer mp2 = MediaPlayer.create(this, R.raw.two);
two.setOnClickListener(new OnClickListener(){
public void onClick(View v) {
mp2.start();
}
});
Ok, this one works:
Button one = (Button)this.findViewById(R.id.button1);
final MediaPlayer mp1 = MediaPlayer.create(this, R.raw.n);
one.setOnClickListener(new OnClickListener(){
#Override
public void onClick(View v) {
if (mp1.isPlaying()) {
mp2.pause();
}
else {
mp2.start();
}
;
}});
The one with Pause above it works, but If I want to stop the music, it does not work.
Following not working:
#Override
public void onClick(View v) {
if (mp1.isPlaying()) {
mp2.stop();
}
else {
mp2.start();
}
;
}});
I get error: start called in state 0
error (-38, 0)

According to http://developer.android.com/reference/android/media/MediaPlayer.html, I suppose you could do something like this:
Button two = (Button)this.findViewById(R.id.button2);
final MediaPlayer mp2 = MediaPlayer.create(this, R.raw.two);
two.setOnClickListener(new OnClickListener(){
public void onClick(View v) {
// If the music is playing
if(mp2.isPlaying() == true)
// Pause the music player
mp2.pause();
// If it's not playing
else
// Resume the music player
mp2.start();
}
});
You can actually write just
if(mp2.isPlaying())
instead of
if(mp2.isPlaying() == true)
It's just for the sake of understanding what is going on.

You could have a boolean check to see if it is started (and set the boolean to false) and if so stop the music, if not start it (and set the boolean to true). Something like:
public void onClick(View v)
{
if(musicPlaying == false)
{
mp2.start();
musicPlaying = true;
}
else
{
mp2.stop();
musicPlaying = false;
}
}

if(mp2.isPlaying()) {
mp2.pause();
} else {
mp2.start();
}

This is what I used to start and stop the music, you must prepare the MediaPlayer for playback. Note: this will start the music from where it stopped.Mediaplayer prepare() methodIf you are streaming music you should use prepareAsync ()
musicButton = (Button) findViewById(R.id.btn_dj_player);
musicButton.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
if (mp.isPlaying()) {//check if a song is already playing
mp.stop();
try {
mp.prepare();//get the mediaplayer reeady for playback
} catch (IllegalStateException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}else {
mp.start();
}
}
});

If you have only one sound and you want it to start or stop with only one button than this may help .
Button button_name = (Button)this.findViewById(R.id.Your_button_id_Here);
final MediaPlayer mp = MediaPlayer.create(this, R.raw.YOur_audio_File_name_here);
button_name.setOnClickListener(new OnClickListener(){
public void onClick(View v) {
if(mp.isPlaying())
{
mp.pause();
}
else
{
mp.start();
}
}
});

Have you tried using the seekTo() function?
Something like:
if (mp.isPlaying()) {
mp.stop();
mp.prepareAsync();
mp.seekTo(0);
} else {
mp.start();
}
}
I am just guessing here, but might be worth looking into. :-)

I accomplished this as follows:
I declared a boolean variable:
boolean isButtonClicked = false;
Then I set up an if else in a method like so:
initPlaySound()
{
if(isButtonClicked)
{
player.start();
} else{
player.stop();
}
Lastly I set up an onClick of the button within the method:
button.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
isButtonClicked = !isButtonClicked;
initPlaySound();
}
});
Basically, when the button is first clicked the boolean is set to the opposite of its' current state (false to true) and the code within the if executes. Once the button is clicked again the boolean is set to the opposite again (true to false) and the sound stops.

I solved this problem in a manual way. If sound is playing, i wrapped sound into beginning(seekTo(0)), then paused the sound. If sound is already paused, only seekTo(0) is called.
public void onClick(View v) {
if(mp.isPlaying()){
mp.seekTo(0);
mp.pause();
}
else{
mp.seekTo(0);
}
} ;

Add a global variable boolean flag=false;
if(flag==false)
{
mp=MediaPlayer.create(this, R.raw.abc);
mp.start();
playbutton.setText("Pause");
flag=true;
}
else if(mp.isPlaying()&&flag==true)
{
mp.pause();
playbutton.setText("Play");
flag=false;
}
This code will work if you want to use the same button as PLAY/PAUSE in your app. Hope this helps. Add this code in the button onClick() function which you are using to play or pause.

Releasing consumed memory after using MediaPlayer

I'm developing an application containing 100s of sound effects.
after playing some of the sounds the application force closes. I understood that the problem would be consuming all the available space of the memory. I tried using Release() method but after this method is called I'm not able to play the sound again.
I also tried using onDestroy() method to set the object of the mediaplayer to null but since these kind of objects must be final I can't do this.
What is your suggestion?
Here is my code:
final MediaPlayer mp1 = MediaPlayer.create(MainActivity.this, R.raw.a1);
btn1.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if (i[0] == false)
{
mp1.start();
Toast.makeText(getBaseContext(), "horn", Toast.LENGTH_SHORT).show();
b1.setBackgroundResource(R.drawable.stop_button);
i[0] = true;
}
else
{
mp1.pause();
mp1.seekTo(0);
b1.setBackgroundResource(R.drawable.horn);
i[0] = false;
}
}
});
mp1.setOnCompletionListener(new OnCompletionListener() {
#Override
public void onCompletion(MediaPlayer mp) {
b1.setBackgroundResource(R.drawable.horn);
}
});

Have you tried something like this?
You can call release() in OnDestroy() method.
#Override
public void onDestroy(){
super.onDestroy();
mp.release();
}
