I'm working on a project in which I have to load 6 different sounds in one activity and play all sound on button click.The sound file are not so big,but the problem is that maybe they will be more.So my question is which is the fastest way to load sound files in a single activity.For test purposes I used res/raw folder to store the sound files and tried with two different method to play the files,but the result did not satisfied me.Here is the two different types of code :
Method 1:
Button first = (Button) findViewById(R.id.one);
Button second = (Button) findViewById(R.id.two);
first.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
MediaPlayer mp = MediaPlayer.create(SoundFXActivity.this, R.raw.drumtwo);
mp.start();
mp.setOnCompletionListener(new OnCompletionListener() {
#Override
public void onCompletion(MediaPlayer mp) {
// TODO Auto-generated method stub
mp.release();
}
});
}
});
second.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
MediaPlayer mp = MediaPlayer.create(SoundFXActivity.this, R.raw.drumone);
mp.start();
mp.setOnCompletionListener(new OnCompletionListener() {
#Override
public void onCompletion(MediaPlayer mp) {
// TODO Auto-generated method stub
mp.release();
}
});
}
});
Method 2:
private SoundPool spool;
private int soundID,soundID2;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
this.setVolumeControlStream(AudioManager.STREAM_MUSIC);
spool = new SoundPool(10, AudioManager.STREAM_MUSIC, 0);
soundID = spool.load(this, R.raw.drumone, 1);
soundID2 = spool.load(this, R.raw.drumtwo, 1);
Button three = (Button) findViewById(R.id.three);
three.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Sound();
}
});
}
public void Sound(){
AudioManager audioManager = (AudioManager) getSystemService(AUDIO_SERVICE);
float volume = (float) audioManager.getStreamVolume(AudioManager.STREAM_MUSIC);
spool.play(soundID, volume, volume, 1, 0, 1f);
};
But the problem is that the both methods are slow..I need to find a way a faster way to play the sounds..but now there is like almost a second after I click the button to play the sound.
Can you give me some advice how to play the sounda faster.Should I load them into a cache when the application starts or save them in database or somewhere else (I don't think database is a good option as a matter of fact,but I want to hear some suggestions).Or maybe load them from assets folder,but I think it still going to be slow.
So any ideas or suggestions?
Thanks in advance!
You could create the media players in your onCreate and then the buttons will just make them play. That would be the easiest solution, I would say.
Alternatively, depending on how important it is to you and how much work you want to do, you could consider using JetPlayer:
here's android development page for media:
http://developer.android.com/guide/topics/media/index.html
The page on the JetPlayer class:
http://developer.android.com/reference/android/media/JetPlayer.html
and the page on creating the JET files:
http://developer.android.com/guide/topics/media/jet/jetcreator_manual.html
If you implemented this it would likely work best but would definitely be the most work.
JetPlayer basically lets you have one audio file (i think it's a MIDI file) with multiple tracks that you mute and unmute as you please. I have no personal experience with it and have just read the docs some, but it seems like it would be very useful for any situation with more than one sound.
Edit: Also, it's worth mentioning this mailing list and in case the link ever changes this google search in case anyone is interested in android audio topics.
If you want to have the less delay you must use OpenSL in c++, From jelly bean is the faster sound player
SoundPool is working fine, you can see an example with the Hexiano project. However, you must preload the sounds into SoundPool, because it takes a lot of time to decode the file and store them in-memory before being able to use them. But once the sounds are loaded, there's no noticeable delay between key press and sound output.

When I touch sound play sound but when I touch another it stop play this sound. I need to sound don't stop playing.
public void onClick(View v) {
mSoundManager.playSound(1);
}
});
Button SoundButton2 = (Button)findViewById(R.id.sound2);
SoundButton2.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
mSoundManager.playSound(2);
}
});
Button SoundButton3 = (Button)findViewById(R.id.sound3);
SoundButton3.setOnClickListener(new OnClickListener() {`enter code here`
public void onClick(View v) {
mSoundManager.playSound(3);
Your code in my comment shows that you have initialized your sound pool with 1 as the value for maxStreams. If you set this value to the maximum amount of sounds you want to be able to play at the same time, it should work.
You have mSoundPool = new SoundPool(1, AudioManager.STREAM_MUSIC, 0);
If you change that to mSoundPool = new SoundPool(5, AudioManager.STREAM_MUSIC, 0);
You will be able to play 5 sounds at once.
I'd need to take a look at your sound manager class to have a better idea of what is wrong with it. However, it is perfectly possible.
Take a look at this:

I'm trying to create a simple soundboard for my 3 year old and have run into quite a dilema, I thought I had found the best possible way to code the soundboard but have run into an issue when the button is clicked nothing happens??
The code is clean, no indication of errors so I'm at my wits end.
Your help is very much appreciated.
public class Player extends Activity implements OnClickListener {
MediaPlayer mp;
#Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Button Button1 = (Button)findViewById(R.id.Button1);
Button1.setOnClickListener(this);
}
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
mp = MediaPlayer.create(this, R.raw.splashsound);
mp.start();
while (mp.isPlaying()){
};
mp.release();
}
};
You need to setup the AudioStream with the setAudioStreamType()
mp = MediaPlayer.create(this, R.raw.ursoundboardtrack);
mp.setAudioStreamType(AudioManager.USE_DEFAULT_STREAM_TYPE);
mp.prepare();
mp.start();
Have you made sure that your splashsound is in a .wav format ?
If it is'nt then this App will never work as it needs to be in a .wav format not a .mp3 or .wma or any other type of audio format it has to be in a .wav format.
If your splashsound is in another audio format but .wav then you will have to convert it to a .wav and import it back into your project and delete the old one and hopefully it should work :)
i have a button that plays a sound.
When i push the button multiple times, it plays the sound multiple times.
This is oke, i want this.
But when i click the stop button it must stop all sounds currently playing.
I used:
while (mediaPlayer.isPlaying()){mediaPlayer.stop();}
but it is not working, the sounds keep on playing. Can someone help me?
Here is my full code:
public class HelloSoundboard extends Activity {
MediaPlayer mediaPlayer;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Button item1 = (Button)findViewById(R.id.item1);
item1.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) {
mediaPlayer = MediaPlayer.create(getBaseContext(), R.raw.atyourservice);
mediaPlayer.start();
}
});
Button stop = (Button)findViewById(R.id.stop);
stop.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) {
while (mediaPlayer.isPlaying()){mediaPlayer.stop();}
// mediaPlayer.stop();
}
});
}
}
SoundPool is a much better alternative for this purpose. I would caution strongly against instantiating multiple MediaPlayer instances as most systems do not have the resources to generate many parallel active instances. You wil find on many device that hitting the button upwards of 5 times will cause a memory based crash.
As far as stopping all active streams, there is not baked-in function for this, but it's easy to accomplish in a manner to similar to your existing code. As a side note, there is an autoPause() method, which halts all streams, but it doesn't truly end their playback (as the method name insinuates). Here is a simple example to manage your audio streams:
//SoundPool initialization somewhere
SoundPool pool = new SoundPool(10, AudioManager.STREAM_MUSIC, 0);
//Load your sound effect into the pool
int soundId = pool.load(...); //There are several versions of this, pick which fits your sound
List<Integer> streams = new ArrayList<Integer>();
Button item1 = (Button)findViewById(R.id.item1);
item1.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) {
int streamId = pool.play(soundId, 1.0f, 1.0f, 1, 0, 1.0f);
streams.add(streamId);
}
});
Button stop = (Button)findViewById(R.id.stop);
stop.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) {
for (Integer stream : streams) {
pool.stop(stream);
}
streams.clear();
}
});
It is much more memory efficient to manage a list of streamID values than MediaPlayer instances, and your users will thank you. Also, note that it is safe to call SoundPool.stop() even if the streamID is no longer valid, so you don't need to check for existing playback.
HTH
I'm not sure about this, but I think is better if you use a SoundPool.
"SoundPool is designed for short clips which can be kept in memory decompressed for quick access, this is best suited for sound effects in apps or games".
"MediaPlayer is designed for longer sound files or streams, this is best suited for music files or larger files".
You can use a list of MediaPlayers:
List<MediaPlayer> mps = new ArrayList<MediaPlayer>();
Button item1 = (Button)findViewById(R.id.item1);
item1.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) {
MediaPlayer mp = MediaPlayer.create(getBaseContext(), R.raw.atyourservice);
mp.start();
mps.add(mp);
}
});
Button stop = (Button)findViewById(R.id.stop);
stop.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) {
for (int i = mps.size() - 1; i >= 0; --i) { //changed ++i to --i
if (mps.get(i).isPlaying()) {
mps.get(i).stop();
}
mps.remove(i);
}
}
});
I am getting problems in playing audio(mp3) files this music files are like click sounds its residing at the raw folder, the problem is if there are many clicks at random intervals it throws an exception of nullPointer. It occurs anywhere when the click is done and anytime, is it related to the memory issue or MediaPlayer related problem, pls any suggestion will be appreceated.
Its simple media player object that i m calling, but its a games so on touch it plays the files, so in game i have many things to drag so i want a click sound at that time, sometime it works fine but when exceeds certain limit it throws null pointer exceptions. this is the code:
MediaPlayer mp= MediaPlayer.create(context,R.raw.soun1);
mp.start();
thats it:
just try this ::
MediaPlayer mp = new MediaPlayer();
mp= MediaPlayer.create(this,R.raw.soun1);
mp.start();
permission in manifest file:::
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"></uses-permission>
To play media player...we need two classes..
let us suppose mainactivity.java is our first file..
here we define two buttons - start_button & stop_button
mButton_start.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
Intent mIntent=new Intent(MainActivity.this,maservice.class);
startService(mIntent);
}
});
mButton_stop.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
Intent mIntent=new Intent(MainActivity.this,maservice.class);
stopService(mIntent);
}
});
maservice.java is our another java file. Here we define media player and also there should be 3 methods: onCreate(), onStart(), onDestroy().
Here is the code:
MediaPlayer mPlayer;
#Override
public void onCreate()
{
super.onCreate();
mPlayer=MediaPlayer.create(this, R.raw.kyun);
mPlayer.setLooping(true);
}
#Override
public void onStart(Intent miIntent, int startid)
{
super.onStart(miIntent, startid);
mPlayer.start();
}
#Override
public void onDestroy()
{
super.onDestroy();
mPlayer.stop();
}
We also have to define these java files in manifest file
mainactivity.java is defined under activity tag
but maservice.java is defined under service tag
I got my answer, its SoundPool, especially created when the concern of game like application where the sound files are used continuously, so here we should use SoundPool except of MediaPlayer.
The issue is with the MP3 encoding. I tried with the same code, few work and few don't. So please try with a different one if it shows up the same error next time.
How do I set up an audiofile to play when a user touches an image.
Where should I store the audio file and what code should I use to actually play the file?
I don't want to bring up the MediaPlayer interface or anything like that.
I was thinking of doing it like this:
foo = (ImageView)this.findViewById(R.id.foo);
foo.setOnClickListener(this);
public void onClick(View v) {
if (foo.isTouched()) {
playAudioFile();
}
}
Thanks
This won't create a bring up the MediaPlayer interface... it will just play the sound you want.
Button boton = (Button) findViewById(R.id.boton);
boton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
MediaPlayer mp = MediaPlayer.create(TestSonido.this, R.raw.slayer);
mp.start();
}
});
In this case, R.raw.slayer represents an audio file called slayer.mp3 that is stored in the res/raw/ folder and once you click the button the droid will rock you...
You can also achieve the same using SoundPool.
MediaPlayer first loads the whole sound data in memory then play, so it produces some lag when we switch among sounds frequently.
SoundPool is a better option with small size sound file and produces better result with .ogg media file.
SoundPool pl = new SoundPool(5, AudioManager.STREAM_MUSIC, 0);
// 5 indicates the maximum number of simultaneous streams for this SoundPool object
pl.setOnLoadCompleteListener(new OnLoadCompleteListener() {
#Override
public void onLoadComplete(SoundPool soundPool, int sampleId, int status) {
// The onLoadComplet method is called when a sound has completed loading.
soundPool.play(sampleId, 1f, 1f, 0, 0, 1);
// second and third parameters indicates left and right value (range = 0.0 to 1.0)
}
});
Button btn = findViewById(R.id.boton);
btn.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
int sound = pl.load(this, R.raw.sound_01, 0);
}
});
public void aud_play(View view) {
if (!mp.isPlaying()) { //If media player is not playing it.
mp = MediaPlayer.create(this, R.raw.audio_name);
mp.start();
} else {// Toast of Already playing ...
}
}
