i'am trying to develop an app in android with 2 buttons. the first button must pause and restart the music if you state is on or off. but this code doesn't works, why?
public class MainActivity extends Activity {
MediaPlayer sound;
Boolean pulsado=false;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
this.setVolumeControlStream(AudioManager.STREAM_MUSIC);
sound=MediaPlayer.create(getBaseContext(),R.raw.gaitas);
sound.setLooping(true);
sound.start();
}
public void boton1(View v){
if(pulsado==false){
sound.stop();
pulsado=true;
}else{
sound.reset();
}
}
public void boton2(View v){
Intent i=new Intent(this,ActivityB.class);
startActivity(i);
}
Android documentation says about MediaPlayer.reset() -- 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().
For your purpose, you could use MediaPlayer.create(...) again to setDataSource to the MP and prepare it for playing.
if (pulsado == false) {
sound.stop();
sound.reset();
pulsado = true;
} else {
sound = MediaPlayer.create(getBaseContext(), R.raw.song);
sound.setLooping(true);
sound.start();
pulsado = false;
}
If you are looking for pausing the song, you could rather call sound.pause() and in else block simple sound.start() should be enough to resume the song.

I am creating a game, I want to play a background music for one activity only(For main menu of game), my code shown below, The problem is that the music plays more than one time, I want to play the same music also when activity Resumes.
public class Menu extends Activity {
MediaPlayer mp
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.menu);
mp = MediaPlayer.create(Menu.this, R.raw.adalante);
if(!mp.isPlaying()) {
mp.start();
}
public void play(View ButtonClicked) {
mp.stop();
mp.release();
//mp = MediaPlayer.create(Menu.this, R.raw.l);
//mp.start();
goToActivity(Game.class);
}
#Override
public void onResume() {
super.onResume(); // Always call the superclass method first
//coins
coin.setText(data.getString("coin"));
mp = MediaPlayer.create(Menu.this, R.raw.adalante);
if(!mp.isPlaying()) {
mp.start();
}
//mps.release();
}
In your onResume don't initialise MediaPlayer again and again. It creates new instance every time when you come to onResume. So add a check in onResume like this :
#Override
protected void onResume() {
super.onResume();
if (mp==null)
mp=MediaPlayer.create(MainActivity.this,R.raw.adalante);
if (!mp.isPlaying())
mp.start();
}
and additionally add this for prevention to play when activity goes to onPause
#Override
protected void onPause() {
super.onPause();
mp.pause();
}
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);
}
}
While pressing start button it starts playing the mp3 file, but it doesn't stop while pressing Stop button, I have been through few examples but couldn't find the exact solution
public Button play;
public Button stop;
MediaPlayer mp;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
play = (Button)findViewById(R.id.played);
stop = (Button)findViewById(R.id.stopped);
play.setOnClickListener(this);
stop.setOnClickListener(this);
}
public void onClick(View v) </br>
{
mp = MediaPlayer.create(this,R.raw.you);
if(v==play && !mp.isPlaying()){
mp.start();
}
//below part of code executes but doesn't stop the player
else if (v==stop){
mp.stop();
mp.release();
}
}
Do like this :
public void onClick(View v) {
switch (v.getId()) {
case R.id.played:
if(mp==null || !mp.isPlaying()){
mp = MediaPlayer.create(this,R.raw.you);
mp.start();
}
break;
case R.id.stopped:
if(mp!=null && mp.isPlaying()){
mp.stop();
mp.release();
}
break
default:
break;
}
}
mp = MediaPlayer.create(this,R.raw.you);
create returns a new instance every time you call it. So you are invoking stop() on an instance of mp different from the one upon you called start(). You should call create once, in the onCreate for instance
I am new to Android programming and i have a problem that i can not solve without your help...Please, give me a hand... ;-)
When i start playing my audio file, i can not stop it. Instead, I am quitting the application.
I play audio file with this code:
public class Word1Audio extends Activity {
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.word1video);
MediaPlayer mediaPlayer = MediaPlayer.create(this, R.raw.lige);
mediaPlayer.start();
}
}
HOWEVER, when i try to stop it when the back button is pressed by this piece of code
#Override
public void onBackPressed() {
// do something on back.
return;
}
my applications closes down and audio continues to play...
Do you have an idea why the application closes down? And how can i just stop the music and go back to the previous page...??
Thank you for your time and help... :-)
you could try
MediaPlayer mediaPlayer;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.word1video);
mediaPlayer = MediaPlayer.create(this, R.raw.lige);
mediaPlayer.start();
}
#Override
public void onBackPressed() {
if( mediaPlayer.isPlaying() ) {
mediaPlayer.stop();
}
super.onBackPressed();
}
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);
}
});
