Android Studio- Media Player doesn't play sound On Genymotion? - android

I am trying to build a small app which plays a sound when we click on the button. But I am not able to play the sound. Don't know what the problem is. Please help me on this. Below is the code.
public class MainActivity extends AppCompatActivity {
private Button button;
private MediaPlayer mediaPlayer;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mediaPlayer = new MediaPlayer();
mediaPlayer = MediaPlayer.create(getApplicationContext(),R.raw.song);
button = (Button)findViewById(R.id.mediaButtonId);
button.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
mediaPlayer.start();
}
});
}
}
Note:-Sorry guys,I thought that the problem is with my code but the app is running perfectly fine on my phone,so its the problem with my genymotion emulator.Can anyone please suggest me the solution for this.By the way,I am using Mac OSX.


The MediaPlayer has its own lifecycle. You can't just create the instance and then start to play. First you have to prepare it and then play it.
You can prepare your mediaplayer either sync or asynchronously.
Something along the lines of:
MediaPlayer mediaPlayer= new MediaPlayer();
mediaPlayer=MediaPlayer.create(getApplicationContext(),R.raw.song);
mediaPlayer.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
#Override
public void onPrepared(MediaPlayer mediaPlayer) {
mediaPlayer.start();
}
});
mediaPlayer.prepareAsync();
Or, if you want to do it synchronously
MediaPlayer mediaPlayer= new MediaPlayer();
mediaPlayer=MediaPlayer.create(getApplicationContext(),R.raw.song);
try {
mediaPlayer.prepare();
} catch (IOException e){
}
mediaPlayer.start();
Just make sure you prepare it before you play it.
Media Player lifecycle: https://developer.android.com/reference/android/media/MediaPlayer.html


You need to make sure the media player is ready before you can play it, so you set the onPreparedListener to handle this for you, like so:
MediaPlayer mp = new MediaPlayer();
mp = MediaPlayer.create(getApplicationContext(),R.raw.song);
mp.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
#Override
public void onPrepared(MediaPlayer mediaPlayer) {
mp.start();
}
});
button = (Button)findViewById(R.id.mediaButtonId);
button.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
mp.prepareAsync();
}
});
There will be a slight delay from when you press the button to the sound playing this way. Another way to do it could be to disable the button until the media player has prepared and then in the onclick of the button you could just call mp.start(); when the button has been enabled.

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...

Media Player start stop start

I am making a new android sound application. I made a clickable button to play sound when I click on it. But I also want it to stop playing sound when I click for the second time. That part works fine now here is the problem, when I click again on button to play sound again, it doesn't play it, Media player is completely stopped. I was looking on forums but I can't seem to find an answer that could help me.
Here is my Activity:
MediaPlayer mpButtonClick1;
MediaPlayer mpButtonClick2;
#Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.prvi);
final MediaPlayer mpButtonClick1 = MediaPlayer.create(this, R.raw.spalshm);
final MediaPlayer mpButtonClick2 = MediaPlayer.create(this, R.raw.splashs);
Button dugme = (Button) findViewById(R.id.dugme);
dugme.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if (mpButtonClick1.isPlaying()) {
mpButtonClick1.stop();
mpButtonClick1.reset();
}
else {
mpButtonClick1.start();
}
}
});
When I try to write mpButtonClick1.prepare(); I get error Unhandled Exception Type IOE exception

Try to use pause instead of stop.
Reason: if you pause the MediaPlayer, then you can resume it later. However, if you use stop, almost any other method won't work and you will have to prepare the MediaPlayer again (or create a new one).
More info: here and here
PS: don't forget to release the memory when you finish using the resources.

Try this:
You should use only one mediaplayer object
public class PlayaudioActivity extends Activity {
private MediaPlayer mp;
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Button b = (Button) findViewById(R.id.button1);
Button b2 = (Button) findViewById(R.id.button2);
final TextView t = (TextView) findViewById(R.id.textView1);
b.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
stopPlaying();
mp = MediaPlayer.create(PlayaudioActivity.this, R.raw.far);
mp.start();
}
});
b2.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
stopPlaying();
mp = MediaPlayer.create(PlayaudioActivity.this, R.raw.beet);
mp.start();
}
});
}
private void stopPlaying() {
if (mp != null) {
mp.stop();
mp.release();
mp = null;
}
}
}

Change your class with below code:
remove reset();.
init well all components:
MediaPlayer mpButtonClick1;
MediaPlayer mpButtonClick2;
#Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.prvi);
mpButtonClick1 = MediaPlayer.create(this, R.raw.spalshm);
mpButtonClick2 = MediaPlayer.create(this, R.raw.splashs);
Button dugme = (Button) findViewById(R.id.dugme);
dugme.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if (mpButtonClick1.isPlaying()) {
mpButtonClick1.stop();
}
else {
mpButtonClick1.start();
}
}
});

You're calling mpButtonClick1.reset() after mpButtonClick1.stop() - don't do that:
if (mpButtonClick1.isPlaying()) {
mpButtonClick1.stop();
mpButtonClick1.reset(); //<--------- calling reset(), remove this line
}
The docs for reset() say:
Resets the MediaPlayer to its uninitialized state. After calling this method, you will have to initialize it again by setting the data source and calling prepare().
Remove mpButtonClick1.reset() and it should work.
Keep in mind that MediaPlayer works as a state machine, which means that if you call methods in the wrong order, you'll get problems. Please read about MediaPlayer here and here.

Hey please use following
for stop -> media player
mp.seekTo(0);
mp.pause();
again for start just call
mp.start();

In my experience when I need to play multiple times and I may need to stop one play to start another play, (like in the case of multiple buttons), I just create another player, making sure that I release the resources for the previous one. To stop just use
mediaPlayer.stop();
But for play use something like this (adapt the logging to your specific needs) to create/recreate your player:
private boolean createMediaPlayer()
{
if (mediaPlayer!=null)
{
if(mediaPlayer.isPlaying())
{
mediaPlayer.stop();
mediaPlayer.reset();
mediaPlayer.release();
mediaPlayer=null;
}
}
mediaPlayer = new MediaPlayer();
mediaPlayer.setVolume(1f, 1f);
try
{
mediaPlayer.setAudioStreamType(Interop.PRIMARY_STREAM);
mediaPlayer.setDataSource(m_soundFile);
mediaPlayer.prepare();
return true;
// Interop.logDebug(TAG + "-loadAudio: SUCCESS" + m_soundFile);
} catch (Exception e)
{
Interop.logError(TAG + "-LoadAudio for Clic Sound: audioPlayer prepare failed for current file: " + m_soundFile);
Interop.logError(TAG + "-Exception: " , e);
return false;
}
}
and than use
if (createMediaPlayer())
mediaPlayer.start();
this will ensure proper release of the resources used by the media player.

A simple solution is to Use pause instead of stop and the seek to the beginning of the song.

I know that this question is quite old but recently while learning Android, I also got stuck at this point and found a very simple solution which I'd like to share with everyone.
Instead of trying to stop or reset the media, you can just seek back to the starting position.
mediaPlayer.seekTo(0);
For reference, I am also posting my code below:
public class MainActivity extends AppCompatActivity {
MediaPlayer mp;
public void play(View view) {
mp.start();
}
public void pause(View view) {
mp.pause();
}
public void stop(View view) {
// this seeks to the beginning of the file
mp.seekTo(0);
}
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mp = MediaPlayer.create(this, R.raw.sample_audio);
}
}

play the same sound in android without waiting for the previous to end

guys scenario is that suppose i click a button, the sound plays and within the duration of that track i again click the button and want to play it from the beginning. i tried with the following code, but no success.
code is :
public class SoundtestActivity extends Activity {
/** Called when the activity is first created. */
MediaPlayer mp;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
mp = MediaPlayer.create(this, R.raw.gun_shot);
Button click=(Button) findViewById(R.id.bt1);
click.setOnClickListener((new View.OnClickListener() {
#Override
public void onClick(View v) {
if(mp.isPlaying())
mp.reset();
mp.start();
}
}));
}
}

Try this code
mp.setOnCompletionListener(new OnCompletionListener() {
#Override
public void onCompletion(MediaPlayer mp) {
mp.release();
mp.start();
}
});
Or replace mp.start(); by mp.reset(); in this code

Best way and the easiest way is =
mp.setLooping(true);
And yes it does work, just simply add this line after mp.start() and nothinfg else is required

You just need to comment the following lines and shift your Media player instance in the button's listener method, bingo your done with multiple media players playing parallel to each other
Button click=(Button) findViewById(R.id.bt1);
click.setOnClickListener((new View.OnClickListener() {
#Override
public void onClick(View v) {
mp = MediaPlayer.create(this, R.raw.gun_shot); // ADD THIS LINE HERE
if(mp.isPlaying()){
mp.stop(); //ADDED TO STOP FIRST
mp.release(); //ADDED TO RELEASE RESOURCES
}
mp.start();
}
}));
