Changing audio button from play to pause when clicked and vice versa

I want a play button in my app that when clicked plays the audio and changes to pause, and when the pause button is clicked the audio stops and the button changes to play again and so on. But the button is not working as expected. Please help. I'm adding my java code below.
public class surah extends AppCompatActivity {
MediaPlayer mp = new MediaPlayer();
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_surah);
mp=MediaPlayer.create(surah.this, R.raw.surahkahf);
final ImageView audio = (ImageView)findViewById(R.id.btn);
audio.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if(mp.isPlaying()){
mp.stop();
audio.setBackgroundResource(R.drawable.play);
try {
mp.prepare();
}catch (IllegalStateException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
else {
mp.start();
audio.setImageResource(R.drawable.pause);
}
}
});
}
}

Use audio.setImageResource(R.drawable.play) instead of audio.setBackgroundResource(R.drawable.play). Use mp.pause() instead of mp.stop();

First, as aborocz mentions in comments, you probably intend to pause playback instead of stop it, so the method you want to use is pause(). In that case you would not need to prepare the MediaPlayer again, and it will start from the same place it was paused when playback is resumed.
Second, the isPlaying() method is not particularly appropriate for this purpose. There are race conditions that prevent the desired behavior. From the Android MediaPlayer documentation:
Note that the transition from the Started state to the Paused state
and vice versa happens asynchronously in the player engine. It may
take some time before the state is updated in calls to isPlaying(),
and it can be a number of seconds in the case of streamed content.
Instead, store your own boolean value.
public class surah extends AppCompatActivity {
private MediaPlayer mp;
private boolean isMediaPlaying = false;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_surah);
mp = MediaPlayer.create(surah.this, R.raw.surahkahf);
final ImageView audio = (ImageView)findViewById(R.id.btn);
audio.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if (isMediaPlaying) {
mp.pause();
audio.setBackgroundResource(R.drawable.play);
isMediaPlaying = false;
} else {
mp.start();
audio.setImageResource(R.drawable.pause);
isMediaPlaying = true;
}
}
});
}
}

There is a Google sample project about playing music across different Android platforms, like Phone, Pad, Watch, Auto... It can keep music playing even app is exited. Take a deep look at here , and I think you will be inspired a lot.

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);
}
}

How to add soundButton(on&off) on a activity in android apps?

I Have created a branch activity .Now i wanted to add two button on that branch activity.
When i click on 'sound on' button then my beep sound on start and when i clicked on 'sound off' then my beep sound off. and also they hide simultaneously.
Thank's
MY Code on Activity
#Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.sound_layout);
soundBttnOn =(Button) findViewById(R.id.soundBttnOn);
soundBttnOn.setOnClickListener(
new OnClickListener(){
#Override
public void onClick(View v) {
startMediaPlayer();
}
}
);
soundBttnoff =(Button) findViewById(R.id.soundBttnOff);
soundBttnoff.setOnClickListener(
new OnClickListener(){
#Override
public void onClick(View v) {
stopMediaPlayer();
}
}
);
}
private void startMediaPlayer() {
mediaPlayer = MediaPlayer.create(SoundLayout.this,R.raw.keybutton5);
mediaPlayer.start();
}
private void stopMediaPlayer() {
if( mediaPlayer != null ) {
MediaPlayer mp = null;
mp.stop();
mp.release();
}
}
It showing no problem but it is not working too..:P..I am not able to implement sound.

You can do simple google search to find tons of samples for adding button. However for playing sound file check out the MediaPlayer class.
Button startBtn, stopBtn;
//get the reference of Button
....
final MediaPlayer mp = new MediaPlayer();
startBtn.onClickListener() {
public void onClick(View v) {
try {
mp.setDataSource(path+"/"+audio.mp3);
mp.prepare();
mp.start();
} catch (Exception e) {
e.printStackTrace();
}
}
};
stopBtn.onClickListener() {
public void onClick(View v) {
if(mp.isPlaying()) {
mp.stop();
//hide buttons
stopBtn.setVisibiltiy(View.GONE);
startBtn.setVisibility(View.GONE);
}
}
};
PS: For only on and off, you don't need two buttons, you could do with one button.
EDIT:
For single button, just use the playing state of Media player for deciding about the action to take on button click.
singleBtn.onClickListener() {
public void onClick(View v) {
try {
if(mp.isPlaying()) mp.stop();
else {
mp.setDataSource(path+"/"+audio.mp3);
mp.prepare();
mp.start();
}
} catch (Exception e) {
e.printStackTrace();
}
}
};

How to PLAY/STOP mediaplayer again?

I'm using a button "music" with 2 actions PLAY and STOP , when I click for the first time the music is played , then when I click again it's stopped. However when I click for the second time all actions PLAY/ STOP don't work .
public class Home extends Activity {
boolean isMediaOn=false;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
final ImageButton music=(ImageButton)findViewById(R.id.music);
final MediaPlayer sound=MediaPlayer.create(Accueil.this,R.raw.star);
music.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
// play
if(isMediaOn==false)
{
System.out.println("PLAY");
sound.start();
music.setImageResource(R.drawable.music);
isMediaOn=true;
}
// stop
else
{
System.out.println("STOP");
if(sound.isPlaying()){
sound.reset();
sound.stop();
}
music.setImageResource(R.drawable.no_music);
isMediaOn=false;
}
}
});
Here is a screenshot of my logcat :

You're only allowed to call stop() when the player is in state STARTED, PREPARED, PAUSED or PLAYBACK_COMPLETE. Your reset() call is putting it back into IDLE state, causing stop() to fail.

You probably want to use pause(), as in sound.pause();
The pause() method pauses playback and maintains all other player states (such as file that's being played, location in file, etc).

In http://developer.android.com/reference/android/media/MediaPlayer.html#stop it is clearly stated that
'Once in the Stopped state, playback cannot be started until prepare() or prepareAsync() are called to set the MediaPlayer object to the Prepared state again.'
public class Home extends Activity {
boolean isMediaOn=false;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
final ImageButton music=(ImageButton)findViewById(R.id.music);
final MediaPlayer sound=MediaPlayer.create(Accueil.this,R.raw.star);
music.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
// play
if(isMediaOn==false)
{
System.out.println("PLAY");
try {
sound.prepare();
} catch (Exception e) {
Log.d(Settings.debug, e.toString());
}
sound.start();
music.setImageResource(R.drawable.music);
isMediaOn=true;
}
// stop
else
{
System.out.println("STOP");
if(sound.isPlaying()){
sound.reset();
sound.stop();
}
music.setImageResource(R.drawable.no_music);
isMediaOn=false;
}
}
});

Try this, hope this helps you.
final ImageButton music=(ImageButton)findViewById(R.id.music);
final MediaPlayer sound=MediaPlayer.create(Accueil.this,R.raw.star);
music.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
if(sound.isPlaying()){
sound.stop();
music.setImageResource(R.drawable.no_music);
} else {
sound.start();
music.setImageResource(R.drawable.music);
}
});
