Outrageous number of similar questions exist here, sadly none did help me.
I am trying to play 3 Audio files simultaneously, one is .wav , the other is .3gp and the other is .mp3 . Since the size exceeds more than 1MB , I cannot use Android SoundPool here. So far, everything works well without any error. Here is my code :
MediaPlayer mp = new MediaPlayer();
MediaPlayer songPlayer = new MediaPlayer();
MediaPlayer voicePlayer = new MediaPlayer();
private String song,voice,text;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_time__date);
String temp;
SharedPreferences preferences1 = getSharedPreferences("musicList", MODE_PRIVATE);
song = preferences1.getString("MUSICONE", "");
SharedPreferences preferences2 = getSharedPreferences("recordList",MODE_PRIVATE);
temp = preferences2.getString("VOICEONE","");
voice = Environment.getExternalStorageDirectory()+"/myAppCache2/"+temp;
SharedPreferences preferences3 = getSharedPreferences("TextList",MODE_PRIVATE);
temp=preferences3.getString("ALARMONE","");
text=Environment.getExternalStorageDirectory()+"/myAppCache/"+temp;
try {
mp.setDataSource(text);
mp.prepare();
mp.setLooping(true);
songPlayer.setDataSource(song);
songPlayer.prepare();
songPlayer.setLooping(true);
voicePlayer.setDataSource(voice);
voicePlayer.prepare();
voicePlayer.setLooping(true);
}
catch (IllegalArgumentException e) {
e.printStackTrace();
} catch (SecurityException e) {
e.printStackTrace();
} catch (IllegalStateException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
mp.start();
songPlayer.start();
voicePlayer.start();
}
Now, my query is how do I add a delay to one ore more Audio files, Say If I want to add a delay of 5000 for voicePlayer before it loops again?

You could remove setLooping and use an OnCompletionListener instead. When you get the onCompletion callback, use postDelayed to post a Runnable that starts the player again.
I create a MediaPlayer like in the appended code. Everything works fine, but I've one problem: whenever an alarm is played and I'm connected to headphones, the sound is played on the phone and in the headphones. I would like the phone to be quiet in such a situation.
Actually, if I use the same function to create another music player to play music and set the stream type to AudioManager.STREAM_MUSIC, everything works fine.
I'm getting this behaviour on an android 4.4.4 phone and I know, that this code worked as expected on my old phone... With android 4.3 I think...
int streamVolume = ((AudioManager) getApplicationContext().getSystemService(Context.AUDIO_SERVICE)).getStreamVolume(AudioManager.STREAM_ALARM);
if (streamVolume != 0)
{
mAlarmPlayer = createMediaPlayerIfNeeded(mAlarmPlayer, true, true, false);
try
{
mAlarmPlayer.setDataSource(this, Uri.parse(sound));
mAlarmPlayer.setAudioStreamType(AudioManager.STREAM_ALARM);
mAlarmPlayer.setVolume(streamVolume, streamVolume);
mAlarmPlayer.prepareAsync();
}
catch (IOException e)
{
Log.e("MusicService", "IOException playing alarm: " + e.getMessage());
e.printStackTrace();
}
}
And here is the create function:
private MediaPlayer createMediaPlayerIfNeeded(MediaPlayer player, boolean setListenerOnPrepared, boolean setListenerOnCompletion, boolean setListenerOnError)
{
if (player == null)
{
player = new MediaPlayer();
player.setWakeMode(getApplicationContext(), PowerManager.PARTIAL_WAKE_LOCK);
if (setListenerOnPrepared)
player.setOnPreparedListener(this);
if (setListenerOnCompletion)
player.setOnCompletionListener(this);
if (setListenerOnError)
player.setOnErrorListener(this);
}
else
player.reset();
return player;
}
I use MediaPlayer for playing a single MP3 song from network. Data source is the file downloaded from network. This files comes in chuncks.
Let's assume we have following playing state.
Song duration: 4:00
Current chunck loaded in player: 1:00
Let's say I want to skip some part of a song and seek forward. I do it with MediaPlayer.seekTo() method. If I seek to position (1:40) it is not performed correctly, seek bar goes at start position (00:00) and the playerr stops.
public static void seekTo(int progress) {
try {
MediaPlayer mp = new MediaPlayer();
mp.setDataSource(sFilePath);
mp.prepare();
int offset = (progress * mp.getDuration()) / 100;
if (sCompleted)
return;
sLastSeek = offset;
if (offset > sMediaPlayer.getDuration()) {
sMediaPlayer.reset();
sMediaPlayer.setDataSource(sFilePath);
sMediaPlayer.prepareAsync();
} else {
sMediaPlayer.seekTo(offset);
}
} catch (Exception ex) {
ex.printStackTrace();
}
}
My media player is in a service object of it's own. Here's the create code.
public void onCreate() {
Toast.makeText(this, "My Service Created", Toast.LENGTH_LONG).show();
Log.d(TAG, "onCreate");
player = new MediaPlayer();
try {
player.setDataSource(path);
player.prepare();
} catch (Exception e) {
}
player.setLooping(false); // Set looping
}
It is streaming from online. However, it's pretty choppy 3 minutes later. I want to double buffer this to help remove that. Any ideas on how I should do this?
Have you looked at the android Double Buffer class?
I'm new to Android development and I have a question/problem.
I'm playing around with the MediaPlayer class to reproduce some sounds/music. I am playing raw resources (res/raw) and it looks kind of easy.
To play a raw resource, the MediaPlayer has to be initialized like this:
MediaPlayer mp = MediaPlayer.create(appContext, R.raw.song);
mp.start();
Until here there is no problem. The sound is played, and everything works fine. My problem appears when I want to add more options to my application. Specifically when I add the "Stop" button/option.
Basically, what I want to do is...when I press "Stop", the music stops. And when I press "Start", the song/sound starts over. (pretty basic!)
To stop the media player, you only have to call stop(). But to play the sound again, the media player has to be reseted and prepared.
mp.reset();
mp.setDataSource(params);
mp.prepare();
The problem is that the method setDataSource() only accepts as params a file path, Content Provider URI, streaming media URL path, or File Descriptor.
So, since this method doesn't accept a resource identifier, I don't know how to set the data source in order to call prepare(). In addition, I don't understand why you can't use a Resouce identifier to set the data source, but you can use a resource identifier when initializing the MediaPlayer.
I guess I'm missing something. I wonder if I am mixing concepts, and the method stop() doesn't have to be called in the "Stop" button. Any help?
Thanks in advance!!!
Here is what I did to load multiple resources with a single MediaPlayer:
/**
* Play a sample with the Android MediaPLayer.
*
* #param resid Resource ID if the sample to play.
*/
private void playSample(int resid)
{
AssetFileDescriptor afd = context.getResources().openRawResourceFd(resid);
try
{
mediaPlayer.reset();
mediaPlayer.setDataSource(afd.getFileDescriptor(), afd.getStartOffset(), afd.getDeclaredLength());
mediaPlayer.prepare();
mediaPlayer.start();
afd.close();
}
catch (IllegalArgumentException e)
{
Log.e(TAG, "Unable to play audio queue do to exception: " + e.getMessage(), e);
}
catch (IllegalStateException e)
{
Log.e(TAG, "Unable to play audio queue do to exception: " + e.getMessage(), e);
}
catch (IOException e)
{
Log.e(TAG, "Unable to play audio queue do to exception: " + e.getMessage(), e);
}
mediaPlay is a member variable that get created and released at other points in the class. This may not be the best way (I am new to Android myself), but it seems to work. Just note that the code will probably fall trough to the bottom of the method before the mediaPlayer is done playing. If you need to play a series of resources, you will still need to handle this case.
this is how MediaPlayer.create method works to open a raw file:
public static MediaPlayer create(Context context, int resid) {
try {
AssetFileDescriptor afd = context.getResources().openRawResourceFd(resid);
if (afd == null) return null;
MediaPlayer mp = new MediaPlayer();
mp.setDataSource(afd.getFileDescriptor(), afd.getStartOffset(), afd.getLength());
afd.close();
mp.prepare();
return mp;
} catch (IOException ex) {
Log.d(TAG, "create failed:", ex);
// fall through
} catch (IllegalArgumentException ex) {
Log.d(TAG, "create failed:", ex);
// fall through
} catch (SecurityException ex) {
Log.d(TAG, "create failed:", ex);
// fall through
}
return null;
}
Or, you could access the resource in this way:
mediaPlayer.setDataSource(context, Uri.parse("android.resource://com.package.name/raw/song"));
where com.package.name is the name of your application package
You can use
mp.pause();
mp.seekTo(0);
to stop music player.
Finally, the way it works for me:
public class MainStart extends Activity {
ImageButton buttonImage;
MediaPlayer mp;
Boolean playing = false;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
buttonImage = (ImageButton)findViewById(R.id.ButtonID);
buttonImage.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
if(playing){
mp.stop();
playing = false;
}else{
mp = MediaPlayer.create(getApplicationContext(), R.raw.sound_u_want);
mp.start();
playing = true;
}
}
});
}
}
MR. Rectangle, this message maybe too late for it, but I proudly write these codes to your idea: I have mp for mediaplayer and sescal9 is a button.
....
if(btnClicked.getId() == sescal9_ornek_muzik.getId())
{
mp.start();
mp.seekTo(380);
mp2.start();
mp2.seekTo(360);
mp3.start();
mp3.seekTo(340);
...
}
Recheck your passing parameters not null
Possible reasons
Context may be null
Your media file may be corrupted
