I am working in a gallery of images that include an audio of how the things that the user is viewing on the screen are pronounced, which is executed with a button also included in the screen.
The following code works, but sometimes the audio is cut before it finishes reproducing, the problem with this is that I am not receiving any error log.
View.OnClickListener eventoPlay = (v) → {
#Override
public void onClick(View v) {
btnPlaySound.setClickable(false);
try{
Uri myUri = Uri.parse(urlroot + urlAudio); //global variables by current image
final MediaPlayer mediaPlayer = new MediaPlayer();
mediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
mediaPlayer.setDataSource(getApplicationContext(), myUri);
mediaPlayer.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
#Override
public void onPrepared(MediaPlayer mp) {
mediaPlayer.start();
}
});
mediaPlayer.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
#Override
public void onCompletion(MediaPlayer mp) {
mp.release();
btnPlaySound.setClickable(true);
}
});
mediaPlayer.setOnErrorListener(new MediaPlayer.OnErrorListener() {
#Override
public boolean onError(MediaPlayer mp, int what, int extra) {
btnPlaySound.setClickable(true);
Log.e("Error in media player", String.valueOf(what));
Log.e("Error in media player", String.valueOf(extra));
return false;
}
});
mediaPlayer.prepareAsync();
}catch (Exception e){
e.printStackTrace();
btnPlaySound.setClickable(true);
}
}
};
btnPlaySound.setOnClickListener(eventoPlay);
btnPlaySound.performClick();
These are the scenarios that I have debugged:
-setOnPreparedListener() call naturally, always (the audio starts playing always).
-setOnCompletionListener() call only if the audio was finished playing (if the audio was not cut).
-setOnErrorListener() It never call, regardless of whether the audio is cut.
-catch This block is never executed either, regardless of whether the audio is cut.
I tested in devices like Samsung tab S3, Samsgung tab E, Samsung tab A, Alcatel A3, Xiaomi MiA2, Swissmobility.
In the most powerful devices happens less frequently. but I want this failure never to occur.
Tnks.
You may want to ensure btnPlaySound.setClickable(true) is being called on the UI thread. It could be causing an error. Also the media player may be getting garbage collected before finishing keep a (strong) reference to the MediaPlayer to prevent garbage collection.
Try this to test if it being garbage collected:
View.OnClickListener eventoPlay = (v) → {
#Override
public void onClick(View v) {
btnPlaySound.setClickable(false);
try{
Uri myUri = Uri.parse(urlroot + urlAudio); //global variables by current image
// KEEP A STRONG REFERENCE
mediaPlayer = new MediaPlayer();
mediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
mediaPlayer.setDataSource(getApplicationContext(), myUri);
mediaPlayer.setLooping(false);
mediaPlayer.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
#Override
public void onPrepared(MediaPlayer mp) {
mp.start();
}
});
mediaPlayer.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
#Override
public void onCompletion(MediaPlayer mp) {
mp.release();
btnPlaySound.setClickable(true);
}
});
mediaPlayer.setOnErrorListener(new MediaPlayer.OnErrorListener() {
#Override
public boolean onError(MediaPlayer mp, int what, int extra) {
mp.release();
btnPlaySound.setClickable(true);
Log.e("Error in media player", String.valueOf(what));
Log.e("Error in media player", String.valueOf(extra));
return false;
}
});
mediaPlayer.prepareAsync();
}catch (Exception e){
e.printStackTrace();
btnPlaySound.setClickable(true);
}
}
};
btnPlaySound.setOnClickListener(eventoPlay);
btnPlaySound.performClick();
for recording file output, I use MediaPlayer.
usually, When I button clicked, start media file.
but, sometime not sound play.
/MediaPlayer: mediaplayer went away with unhandled events
W/MediaPlayer-JNI: MediaPlayer finalized without being released
at first I think before the voice file is finished, when clicked button occur this problem.
but even if I press the button repeatedly, sometime not sound play.
source.
player = new MediaPlayer();
player.reset();
player.setAudioStreamType(AudioManager.STREAM_MUSIC);
try {
player.reset();
AssetFileDescriptor assetFileDescriptor =
getApplicationContext().getResource().openRawResourceFd(R.raw.sound);
player.setDataSource(assetFileDescriptor.getFileDescriptor(),
assetFileDescriptor.getStartOffset(), assetFileDescriptor.getLength());
player.prepare();
player.start();
} catch (Exception e) {
e.printStackTrace();
}
player.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
#Override
public void onCompletion(MediaPlayer mediaPlayer) {
if (player != null) {
player.stop();
player.release();
}
}
});
How to fix sometimes not sound play when i button clicked?
thanks.
There's no reason to call MediaPlayer.release() if it will be used again, as calling reset() will release all the memory & codecs that are in use.
init:
player = new MediaPlayer();
player.setAudioStreamType(AudioManager.STREAM_MUSIC);
player.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
#Override
public void onCompletion(MediaPlayer mediaPlayer) {
mediaPlayer.reset();
}
});
Handling button clicks:
void onButtonClicked() {
player.reset();
AssetFileDescriptor assetFileDescriptor =
getApplicationContext().getResource().openRawResourceFd(R.raw.sound);
player.setDataSource(assetFileDescriptor.getFileDescriptor(),
assetFileDescriptor.getStartOffset(), assetFileDescriptor.getLength());
player.prepare();
player.start();
}
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
Here is my code:
private void scanningSoundStart() {
scanningMediaPlayer = MediaPlayer.create(this, R.raw.scanning);
scanningMediaPlayer.setOnPreparedListener(new OnPreparedListener() {
#Override
public void onPrepared(MediaPlayer mp) {
}
});
scanningMediaPlayer.setOnVideoSizeChangedListener(new OnVideoSizeChangedListener() {
#Override
public void onVideoSizeChanged(MediaPlayer mp,int width, int height) {
}
});
scanningMediaPlayer.start();
}
private void scanningSoundStop() {
if (scanningMediaPlayer.isPlaying()) {
scanningMediaPlayer.stop();
//scanningMediaPlayer.release();
}
}
I'm trying to play an mp3 file from my raw folder.
The first function which is used for playing the audio file.
And the second function is used for stopping the playing audio.
I get the following error when I repeatedly playing or stopping the audio.
Error : MediaPlayer(10576): error (-19, 0)
I know that my entire approach of handling mediaplayer is wrong.
Please help me to correct this error.
And if possible suggest me how to handle mediaplayer class efficiently.
Try the following code to play audio file.
public void audioPlayer(String path, String fileName){
//set up MediaPlayer
MediaPlayer mp = new MediaPlayer();
try {
mp.setDataSource(path+"/"+fileName);
mp.prepare();
mp.start();
} catch (Exception e) {
e.printStackTrace();
}
}
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();
