I am having a problem with MediaPlayer class' setOnCompletionListener Method. in my project I have a button, which text is Play, and when I press on it, player starts playing and it's text is changed to Pause. I want to change button's text to Play again once the track has finished playing. I used this code, which doesn't work for me.
//in onCreate() method:
player = MediaPlayer.create(getApplicationContext(), tracks[0]);
player.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
#Override
public void onCompletion(MediaPlayer mp) {
trackBtn.setText("Play");
}
});
Here is how I have it, if you have any more question please let me know:
player.setOnCompletionListener(this);
IntroClip.execute(player);
}
#Override
public void onCompletion(MediaPlayer mp){
trackBtn.setText("Play");
}

I have yet to find an answer to this.
I have a local file (R.raw.Bob); and I am trying to use MediaPlayer to play the file.
Sometimes it plays, sometimes it does not. I have another file which plays seemingly fine every time.
My activity flow is like this: In onCreate I do the following:
MediaPlayer mBackground = MediaPlayer.create(MainAct.this, R.raw.background);
mBackground.start(); // Works as expected.
Now in a different part of the activity I have the following:
MediaPlayer mBob= MediaPlayer.create(MainActivity.this, R.raw.Bob);
mBob.start();
And nothing occurs. I have used Log.i() and the execution goes through the relevant code but the file does not start.
Why does MediaPlayer sometimes work and sometimes does not, and is there a more reliable way of playing sound files?
Try this to start:
MediaPlayer mBob = MediaPlayer.create(MainActivity.this, R.raw.Bob);
mBob.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
#Override
public void onPrepared(final MediaPlayer mp) {
mp.start();
}
});
and this to stop:
mBob.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
#Override
public void onCompletion(MediaPlayer mp) {
mp.stop();
}
});
In an Android app I am using MediaPlayer to play sound files.
This is just for personal use and will not be published.
I have several references to the sound files:
MediaPlayer dooropen = MediaPlayer.create(MainActivity.this, R.raw.dooropen);
MediaPlayer doorclose = MediaPlayer.create(MainActivity.this, R.raw.doorclose);
//...
For example the length of the dooropen sound clip is 2 seconds so after I play it I sleep for 2.5 seconds and then play the doorclose sound clip, like so
dooropen.start();
try{ Thread.sleep(2500); }catch(InterruptedException e){ }
doorclose.start();
The issue I am having is some of my sound files are not playing in the order I have them in.
There does not seem to be any reason why certain sound files do not play, because if I play them at the top of my onCreate() procedure they all play, it is only when I try and play them in a certain order.
You should implement the setOnCompletionListener() of the mediaplayer to get a callback when playback has completed and then load another audio file that needs to start playing.
See MediaPlayer Documentation about the mediaplayer state.
Yes you can use MediaPlayer along with oncompletionListener or you may try reseting the mediaplayer after one audio is completed. example code here. You may also use session id to keep track of which file was playing and which to start now.
mPlayer = new MediaPlayer();
//set other attributes here
mPlayer.setAudioSessionId(1);
mPlayer.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
#Override
public void onCompletion(MediaPlayer mp) {
//check which audio session was playing and set new datasource and session
mPlayer.reset();
//set other data source here and different session id
}
});
Hope it solves your problem.
If you want to play sound in order, try this:
mp1.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
#Override
public void onCompletion(MediaPlayer mp) {
mp2.start();
}
});
mp2.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
#Override
public void onCompletion(MediaPlayer mp) {
mp3.start();
}
});
mp3.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
#Override
public void onCompletion(MediaPlayer mp) {
mp1.start();
}
});
I am working on a application in which i have to play a horn sound and i am having a sound clip of it. Now i want to play this sound file in a loop but i am getting a second lag once its repeat the same file. I am using media player class to play the sound.
Please let me know how i can remove this lag to play a sound file without a lag.
final MediaPlayer mp_horn1 = MediaPlayer.create(this, R.raw.horn_wf);
mp_start.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
#Override
public void onPrepared(MediaPlayer mp) {
mp_start.start();
}
});
Hey use this code for play sound in loop.
final MediaPlayer mp_horn1 = MediaPlayer.create(this, R.raw.horn_wf);
mp_start.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
#Override
public void onPrepared(MediaPlayer mp) {
mp_horn1..setLooping(true);
mp_start.start();
}
});
You have to use this - .setLooping(true);
Hope this will work. All the best.
In Adnroid, at first i declare the mediaplayer by
MediaPlayer mpl;
next I have this in the onCreate method
mp = new MediaPlayer();
mp = MediaPlayer.create(this, R.raw.hit );
mp.setVolume(1, 1);
and a function that's supposed to play a sound when called
public void click()
{
mp.start();
}
yet the problem is that if the user calls this function multiple times, before it has stopped playing the last sound, it will die and stop playing any sounds, before the app is reset.
Any ideas how to fix that?
Thanks!
edit - found a solution:
mp.setOnCompletionListener(new OnCompletionListener() {
public void onCompletion(MediaPlayer mp) {
mpl.release();
}
});
public void click()
{
if( ! mp.isPlaying() ) {
mp.start();
}//if
}//met
you can disable the button.
or you can stop current playing and star
new in onClick()
I am trying to play a looping Ogg file, I tried enabling setLooping(true) but that had no effect so I tried onCompletionListener and that's not working either, could someone clarify what I am doing wrong?
musicPlayer = MediaPlayer.create(mContext, R.raw.overworld);
musicPlayer.setVolume(musicVolume, musicVolume);
// musicPlayer.setLooping(true);
musicPlayer.setOnCompletionListener(new OnCompletionListener() {
#Override
public void onCompletion(MediaPlayer mp) {
musicPlayer.stop();
musicPlayer.seekTo(0);
musicPlayer.start();
Log.d("Sound Manager", "Song Completed");
}
});
Following is my play function,
public void playSong(int id) {
try {
stopSong();
musicPlayer = MediaPlayer.create(mContext, id);
musicPlayer.start();
} catch(Exception e) {
// Ignored
}
}
It's known that MediaPlayer is having problems with ogg files.
You could preferrably switch to another file format.
The other thing is, I would go on trying with setLooping(boolean) as it's most likely using the same scheme and its much more clearly.
Calling seekTo() if the MediaPlayer Object is stopped causes the MediaPlayer to be in an invalid state. You can call pause() instead but I wouldn't call any of these method, why not just seeking? I would guess if you remove the musicPlayer.stop() it will work.
remove ....
musicPlayer.stop();
from
onCompletion(MediaPlayer mp)
onCompletionListener() is not called if your MediaPlayer is set to looping, BUT if you don't have it set to looping, you can always just use a completion listener like so
#Override
public void onCompletion(MediaPlayer mp) {
if(!mp.isPlaying()) {
mp.start();
}
mp.seekTo(0);
}
You also shouldn't call stop() because that stops playback completely, and it doesn't make sense to seek in a video/song that you are not playing.
