I am making a android simple media player for playing a audio files and facing a problem with it.
I want to stop Chronometer and media player
When the current Duration of playing file == total duration of file..?
Here is my demo code.
private void playAudio() {
mediaPlayer = new MediaPlayer();
try {
mediaPlayer.setDataSource(outputFile);
} catch (IOException e) {
e.printStackTrace();
}
try {
mediaPlayer.prepare();
} catch (IOException e) {
e.printStackTrace();
}
mChronometer.setBase(SystemClock.elapsedRealtime());
mChronometer.start();
mediaPlayer.start();
long totalDuration = mediaPlayer.getDuration();
Log.i("MediaPlayer", String.valueOf(totalDuration));
}
here is another code added from answer .
i add the listrner
mediaPlayer.setOnCompletionListener(CompletionListener);
MediaPlayer.OnCompletionListener CompletionListener = new MediaPlayer.OnCompletionListener() {
#Override
public void onCompletion(MediaPlayer mp) {
long totalDuration = mp.getDuration();
}
};
Use onCompletionListener to check when media player has reached end of the media file.
mPlayer.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
public void onCompletion(MediaPlayer mp) {
// do your task
}
});

Media Player
I'm trying to play notification sound even if silent mode is on
Uri uri = Uri.parse(alarmSound);
notification.setSound(uri);
AudioManager mobileMode = (AudioManager) context.getSystemService(Context.AUDIO_SERVICE);
int previousNotificationVolume = mobileMode.getStreamVolume(AudioManager.STREAM_NOTIFICATION);
if (ignoreSilent) {
mobileMode.setStreamVolume(AudioManager.STREAM_NOTIFICATION, mobileMode.getStreamMaxVolume(AudioManager.STREAM_NOTIFICATION), 0);
}
NotificationManager manager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
manager.notify(UNIQUE_ID, n);
try {
// to delay make a space to finish play sound before return back to original stat.
Thread.sleep(2000);
} catch(InterruptedException ex) {
Thread.currentThread().interrupt();
}
mobileMode.setStreamVolume(AudioManager.STREAM_NOTIFICATION, previousNotificationVolume, 0);
This should be option that user enable or disable, I'm trying the code above but the things not going well, the sound heard "sometimes" and the phone return to the Vibration mode instead of silent, I want to handle lollipop case:
In Silent mode , timed or indefinitely.
In priority mode, timed or indefinitely.
In another world, I want something to save full stat and return it as it was.
Or, since I know how to play sound with media player, way to get the stat of phone, and if it is silent, make sound playing as a media, with max sound of media, the following how I can play sound with MediaPlayer :
public static void playSound(Context context, Uri alert) {
MediaPlayer mMediaPlayer = new MediaPlayer();
try {
mMediaPlayer.setDataSource(context, alert);
final AudioManager audioManager = (AudioManager) context
.getSystemService(Context.AUDIO_SERVICE);
if (audioManager.getStreamVolume(AudioManager.STREAM_ALARM) != 0) {
mMediaPlayer.setAudioStreamType(AudioManager.STREAM_ALARM);
mMediaPlayer.prepare();
mMediaPlayer.start();
}
} catch (IOException e) {
Log.e(TAG, e.getMessage());
}
}
And then like this (but I want to know if phone in silent or vibration or priority mode) :
if (ignoreSilent) {
CoreServices.playSound(context, uri);
} else {
// else just follow normal behavior
notification.setSound(uri);
}
Finally, I prefer to solve by switching status, at least I will know how android deal things in this part, and working with API 14+.
public void playSound(){
final MediaPlayer mMediaPlayer;
Uri notification = null;
try {
notification = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
mMediaPlayer = new MediaPlayer();
mMediaPlayer.setDataSource(getApplicationContext(), notification);
// mMediaPlayer = MediaPlayer.create(ctx, notification);
final AudioManager audioManager = (AudioManager) getApplicationContext().getSystemService(Context.AUDIO_SERVICE);
mMediaPlayer.setAudioStreamType(AudioManager.STREAM_ALARM);
try {
mMediaPlayer.prepare();
} catch (IOException e) {
e.printStackTrace();
}
// mMediaPlayer.start();
mMediaPlayer.setLooping(false);
mMediaPlayer.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
public void onPrepared(MediaPlayer arg0) {
/* if (mMediaPlayer != null) {
mMediaPlayer.stop();
}*/
mMediaPlayer.seekTo(0);
mMediaPlayer.start();
}
});
mMediaPlayer.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
#Override
public void onCompletion(MediaPlayer mp) {
}
});
}catch (Exception e){
e.printStackTrace();
}
}
I am making an app that uses sound effects. I would like to know how i can detect when a sound has finished playing and trigger an event .
i tried this :
player = new MediaPlayer();
if (player != null) {
player.reset();
player.release();
}
player.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
#Override
public void onCompletion(MediaPlayer mediaPlayer) {
sonar.setBackgroundResource(R.drawable.sonar_off);
stopPlay();
}
});
if(state==1){
player = MediaPlayer.create(this, R.raw.sonar_slow);
}else if(state==2){
player = MediaPlayer.create(this, R.raw.sonar_medium);
}else if(state==3){
player = MediaPlayer.create(this, R.raw.sonar_fast);
}
try{
player.prepare();
} catch (IllegalStateException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
player.start();
You can set an OnCompleteListener() to the player object. The code for it is:
mPlayer.setOnCompletionListener(new OnCompletionListener() {
#Override
public void onCompletion(MediaPlayer mp)
{
"your code comes here"
}
});
Here the mPlayer is the object of the MediaPlayer which is currently running.
There are multiple ways to play sounds, assuming you use the MediaPlayer class you could register a MediaPlayer.OnCompletionListener
I have a simple mp service to play, pause, resume audio. All works fine.
But, last night I have decided to add a feature for user to route audio to ear-piece or speaker and have been battling with mp.setAudioStreamType().
Problem is that I can't change it while service connected and mp created. I don't want to terminate service and/or unbind and rebind as it would require a lot of refactoring
How do I supposed to change AudioStreamType while playing an audio?
Here is my code:
Player service:
public class PService extends Service {
private MediaPlayer mp = new MediaPlayer();
public static final String PLAYING_FINISHED_MSG = "1";
#Override
public void onCreate() {
super.onCreate();
}
#Override
public void onDestroy() {
mp.stop();
mp.release();
}
private void playSong(String file) {
try {
mp.reset();
mp.setDataSource(file);
mp.setAudioStreamType(MYAPP.getAudioStreamType());
mp.prepare();
mp.start();
mp.setOnCompletionListener(new OnCompletionListener() {
public void onCompletion(MediaPlayer arg0) {
Intent i = new Intent();
i.setAction(MDService.PLAYING_FINISHED_MSG);
sendBroadcast(i);
}
});
toggle route button onclick
currentlyPlayingFile = file;
currentlyPlayingPhone = phone;
lastDurationBeforePause = mpInterface.getCurrentPosition();
if(MYAPP.getAudioStreamType() == AudioManager.STREAM_MUSIC)
{
MYAPP.setAudioStreamType(AudioManager.STREAM_VOICE_CALL);
recording_player_route_button.setImageResource(R.drawable.route_off);
}
else{
MYAPP.setAudioStreamType(AudioManager.STREAM_MUSIC);
recording_player_route_button.setImageResource(R.drawable.route_on);
}
try {
mpInterface.playFile(file);
player_seekbar.setProgress(0);
player_seekbar.setMax(mpInterface.getDuration());
//seekto last millisecond after switching from/to sepaker
if(seekTo>0)
{
mpInterface.seekTo(seekTo);
}
isPauseButtonPressed = false;
handleSeekBarUpdate.postDelayed(handleSeekBarUpdateJob, 1);
} catch (RemoteException e) {
e.printStackTrace();
}
The MODIFY_AUDIO_SETTINGS permission is needed in the Manifest for this to work.
AudioManager am=(AudioManager)getSystemService(Context.AUDIO_SERVICE);
am.setMode(AudioManager.MODE_NORMAL);
MediaPlayer mp=new MediaPlayer();
Uri ringtoneUri=RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
try
{
mp.setDataSource(getApplicationContext(), ringtoneUri);
mp.setAudioStreamType(AudioManager.STREAM_NOTIFICATION);
mp.prepare();
mp.start();
}
catch(Exception e)
{
//exception caught in the end zone
}
I am currently trying to design a simple app that streams an internet radio station. I have the URL for the station and am setting up the Media Player like
MediaPlayer mediaPlayer = new MediaPlayer();
try {
mediaPlayer.setDataSource(URL);
} catch (IllegalArgumentException e) {
e.printStackTrace();
} catch (SecurityException e) {
e.printStackTrace();
} catch (IllegalStateException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
try {
mediaPlayer.prepare();
} catch (IllegalStateException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
mediaPlayer.start();
The program isn't crashing when emulated, but nothing is playing and I am get the following error:
start called in state 0
and right below it is
Error (-38,0)
Does anyone know what this means?
I've read a little about these state errors, but couldn't find anything that applies to my project.
You need to call mediaPlayer.start() in the onPrepared method by using a listener.
You are getting this error because you are calling mediaPlayer.start() before it has reached the prepared state.
Here is how you can do it :
mp.setDataSource(url);
mp.setOnPreparedListener(this);
mp.prepareAsync();
public void onPrepared(MediaPlayer player) {
player.start();
}
It seems like Error -38 means a state-exception (as the error-message indicates). For example if you call start(), before the song was ready, or when you call pause(), even if the song isn't playing at all.
To fix this issue check the state of the mediaPlayer before calling the methods. For example:
if(mediaPlayer.isPlaying()) {
mediaPlayer.pause();
}
Additionally, the MediaPlayer is sending event-messages. Even if you do not need the prepared-event (although it would be a good idea to not start the playback before this event was fired) you must set a callback-listener. This also holds true for the OnErrorListener, OnCompletionListener, OnPreparedListener and OnSeekCompletedListener (if you call the seek method).
Listeners can be attached simply by
mediaPlayer.setOnPreparedListener(new OnPreparedListener() {
#Override
public void onPrepared(MediaPlayer mp) {
// Do something. For example: playButton.setEnabled(true);
}
});
I got this error when I was trying to get the current position (MediaPlayer.getCurrentPosition()) of media player when it wasn't in the prepared stated. I got around this by Keeping track of its state and only calling the getCurrentPosition() method after onPreparedListener is called.
This is my code,tested and working fine:
package com.example.com.mak.mediaplayer;
import android.media.MediaPlayer;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.app.Activity;
public class MainActivity extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
final MediaPlayer mpp = MediaPlayer.create(this, R.raw.red); //mp3 file in res/raw folder
Button btnplay = (Button) findViewById(R.id.btnplay); //Play
btnplay.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View vone) {
mpp.start();
}
});
Button btnpause = (Button) findViewById(R.id.btnpause); //Pause
btnpause.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View vtwo) {
if (mpp.isPlaying()) {
mpp.pause();
mpp.seekTo(0);
}
}
});
}
}
I encountered the same issue few days ago. My audio MediaPlayer works fine on devices with high processing power, but for slow devices, the media player just did not play some time and from LogCat it had many complain about called in wrong state. So I resolved it by calling putting the call to start(), pause(),... in onPrepared() method of OnPreparedListener() as below:
mediaPlayer.prepare();
mediaPlayer.setOnPreparedListener(new OnPreparedListener() {
#Override
public void onPrepared(MediaPlayer mp) {
........
mediaPlayer.start();
....
songControlBtn.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
if (mediaPlayer.isPlaying()) {
mediaPlayer.pause();
} else {
mediaPlayer.start();
}
}
});
mediaPlayer.setOnCompletionListener(new OnCompletionListener() {
#Override
public void onCompletion(MediaPlayer mp) {
............
}
});
}
});
Also try to release any media player that you do not need any more. For example, if you do not want to play the audio or video on background then you should call mediaPlayer.release() in onPause().
i tested below code. working fine
public class test extends Activity implements OnErrorListener, OnPreparedListener {
private MediaPlayer player;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
player = new MediaPlayer();
player.setAudioStreamType(AudioManager.STREAM_MUSIC);
try {
player.setDataSource("http://www.hubharp.com/web_sound/BachGavotte.mp3");
player.setOnErrorListener(this);
player.setOnPreparedListener(this);
player.prepareAsync();
} catch (IllegalArgumentException e) {
e.printStackTrace();
} catch (IllegalStateException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}
#Override
public void onDestroy() {
super.onDestroy();
player.release();
player = null;
}
#Override
public void onPrepared(MediaPlayer play) {
play.start();
}
#Override
public boolean onError(MediaPlayer arg0, int arg1, int arg2) {
return false;
}
}
Some times file are encoded in a way that Android can't decode. Even some mp4 files can not be played. Please try a different file format (.3gp are played most of the time) and see..
You get this message in the logs, because you do something that is not allowed in the current state of your MediaPlayer instance.
Therefore you should always register an error handler to catch those things (as #tidbeck suggested).
At first, I advice you to take a look at the documentation for the MediaPlayer class and get an understanding of what that with states means. See: http://developer.android.com/reference/android/media/MediaPlayer.html#StateDiagram
Your mistake here could well be one of the common ones, the others wrote here, but in general, I would take a look at the documentation of what methods are valid to call in what state: http://developer.android.com/reference/android/media/MediaPlayer.html#Valid_and_Invalid_States
In my example it was the method mediaPlayer.CurrentPosition, that I called while the media player was in a state, where it was not allowed to call this property.
above the picture,you can get the right way.
I solved both the errors (-19,0) and (-38,0) , by creating a new object of MediaPlayer every time before playing and releasing it after that.
Before :
void play(int resourceID) {
if (getActivity() != null) {
//Using the same object - Problem persists
player = MediaPlayer.create(getActivity(), resourceID);
player.setAudioStreamType(AudioManager.STREAM_MUSIC);
player.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
#Override
public void onCompletion(MediaPlayer mp) {
player.release();
}
});
player.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
#Override
public void onPrepared(MediaPlayer mp) {
mp.start();
}
});
}
}
After:
void play(int resourceID) {
if (getActivity() != null) {
//Problem Solved
//Creating new MediaPlayer object every time and releasing it after completion
final MediaPlayer player = MediaPlayer.create(getActivity(), resourceID);
player.setAudioStreamType(AudioManager.STREAM_MUSIC);
player.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
#Override
public void onCompletion(MediaPlayer mp) {
player.release();
}
});
player.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
#Override
public void onPrepared(MediaPlayer mp) {
mp.start();
}
});
}
}
if(length>0)
{
mediaPlayer = new MediaPlayer();
Log.d("length",""+length);
try {
mediaPlayer.setDataSource(getApplication(),Uri.parse(uri));
} catch(IOException e) {
e.printStackTrace();
}
mediaPlayer.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
#Override
public void onPrepared(MediaPlayer mediaPlayer) {
mediaPlayer.seekTo(length);
mediaPlayer.start();
}
});
mediaPlayer.prepareAsync();
It was every much frustrated. So, I got solution which works for me.
try {
if (mediaPlayer != null) {
mediaPlayer.release();
mediaPlayer = null;
}
mediaPlayer = new MediaPlayer();
mediaPlayer.setDataSource(file.getAbsolutePath());
mediaPlayer.setAudioStreamType(AudioManager.STREAM_NOTIFICATION);
mediaPlayer.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
#Override
public void onPrepared(MediaPlayer mediaPlayer) {
mediaPlayer.start();
mediaPlayer.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
#Override
public void onCompletion(MediaPlayer mediaPlayer) {
mediaPlayer.stop();
mediaPlayer.release();
mediaPlayer = null;
}
});
}
});
mediaPlayer.prepare();
} catch (Exception e) {
e.printStackTrace();
}
For me this worked
mp.seekTo(0);
mp.start();
I also got this error i tried with onPreparedListener but still got this error. Finally i got the solution that error is my fault because i forgot the internet permission in Android Manifest xml. :)
<uses-permission android:name="android.permission.INTERNET" />
I used sample coding for mediaplayer. I used in StreamService.java
onCreate method
String url = "http://s17.myradiostream.com:11474/";
mediaPlayer = new MediaPlayer();
mediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
mediaPlayer.setDataSource(url);
mediaPlayer.prepare();
mp = new MediaPlayer();
AssetFileDescriptor afd = mContext.getAssets().openFd(fileName);
mp.reset();
mp.setDataSource(afd.getFileDescriptor(), afd.getStartOffset(), afd.getLength());
mp.prepare();
mp.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
public void onPrepared(MediaPlayer mp) {
mp.start();
}
});
mp.prepareAsync();
I have change setAudioStreamType to setAudioAttributes;
mediaPlayer.setAudioAttributes(AudioAttributes.Builder()
.setFlags(AudioAttributes.FLAG_AUDIBILITY_ENFORCED)
.setLegacyStreamType(AudioManager.STREAM_ALARM)
.setUsage(AudioAttributes.USAGE_ALARM)
.setContentType(AudioAttributes.CONTENT_TYPE_SONIFICATION)
.build());
I am new in android programming and i had same error as this one. so i simply redefined the mp.createmediaPlayer = MediaPlayer.create(getApplicationContext(), Settings.System.DEFAULT_RINGTONE_URI). It may not the true way to do it but it worked fined for me:
try {
mp = MediaPlayer.create(getApplicationContext(), Settings.System.DEFAULT_RINGTONE_URI);
} catch (Exception e) {
e.printStackTrace();
}
mp.start();
