Android Media Player crash when changing datasource - android

I`m using a service to play the music in the background. the user have a list of songs that he can listen online or downloading them and listen offline.
the problem appears when the user is in offline mode. if he downloads a song he can play it with no problems, but if he skip to the next one(not downloaded) and there is not internet, it does not work as expected and this is not a problem. the problem appears when the user skip to previous one which is downloaded, this time its not playing
private void initMediaPlayer() {

how to stop Mediaplayer

I am having 3 tones. I am calling playmusic() function to play 2 of these tones on imageview toggle. when i click on imageview for first time tone1 starts playing. when i click 2nd time on the same imageview tone2 starts playing, but tone1 is not stopped.
my requiremet is , when i click on imageview for -
(1st time - tone1 should start playing).
(2nd time - tone1 should stop playing and tone2 should start playing)
(3rd time - tone2 should stop playing and tone1 should start playing again)
and so on....
String file=null;
int x=0;
public void playMusic(int i) {
x=i;
if(i==1){
file = R.raw.tone1;
}else if(i==2){
file = R.raw.tone2;
}else{
file = R.raw.tone3;
}
mediaPlayer = new MediaPlayer();
mediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
AssetFileDescriptor assetFileDescriptor =
Main2Activity.this.getResources().openRawResourceFd(file);
if(assetFileDescriptor == null) return;
try {
mediaPlayer.setDataSource(
assetFileDescriptor.getFileDescriptor(),
assetFileDescriptor.getStartOffset(),
assetFileDescriptor.getLength()
);
assetFileDescriptor.close();
mediaPlayer.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
#Override
public void onCompletion(MediaPlayer mediaPlayer) {
if(mediaPlayer != null){
mediaPlayer.release();
mediaPlayer = null;
}
}
});
mediaPlayer.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
#Override
public void onPrepared(final MediaPlayer mediaPlayer) {
mediaPlayer.start();
}
});
mediaPlayer.prepareAsync();
} catch (IllegalArgumentException e) {
// HelpFunctions.showLog("ERROR = " + e);
} catch (IllegalStateException e) {
// HelpFunctions.showLog("ERROR = " + e);
} catch (IOException e) {
// HelpFunctions.showLog("ERROR = " + e);
}
}
I did a small modification on your logic and added mediaplayer.reset(). Here is the solution link
public class MainActivity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
final ImageView player = findViewById(R.id.play);
player.setOnClickListener(new View.OnClickListener() {
#Override public void onClick(View v) {
playMusic(1);
}
});
mediaPlayer = new MediaPlayer();
}
int file = 0;
MediaPlayer mediaPlayer;
int x = 0;
public void playMusic(int i) {
x = x + i;
if (x == 1) {
file = R.raw.tone1;
}
else if (x == 2) {
file = R.raw.tone2;
} else {
x = 0;
file = R.raw.tone3;
}
mediaPlayer.reset();
mediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
AssetFileDescriptor assetFileDescriptor =
MainActivity.this.getResources().openRawResourceFd(file);
if (assetFileDescriptor == null) return;
try {
mediaPlayer.setDataSource(
assetFileDescriptor.getFileDescriptor(),
assetFileDescriptor.getStartOffset(),
assetFileDescriptor.getLength()
);
assetFileDescriptor.close();
mediaPlayer.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
#Override
public void onCompletion(MediaPlayer mediaPlayer) {
if (mediaPlayer != null) {
mediaPlayer.release();
}
}
});
mediaPlayer.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
#Override
public void onPrepared(final MediaPlayer mediaPlayer) {
mediaPlayer.start();
}
});
mediaPlayer.prepareAsync();
} catch (IllegalArgumentException e) {
// HelpFunctions.showLog("ERROR = " + e);
} catch (IllegalStateException e) {
// HelpFunctions.showLog("ERROR = " + e);
} catch (IOException e) {
// HelpFunctions.showLog("ERROR = " + e);
}
}
}
when i click 2nd time on the same imageview tone2 starts playing, but tone1 is not stopped.
If that's the only issue, try putting the following line before you call mediaPlayer = new MediaPlayer();:
if (mediaPlayer != null && mediaPlayer.isPlaying()) mediaPlayer.stop();

Unable to stop mediaplayer

I've two radio buttons in a radiogroup and on selection of one radio button it will start music and stop the other sound and on selection of other it will start the next song and stop the previous song. The problem is I'm unable to stop the music. The song keeps on playing in the background. I'm using dialog box to show radio buttons and getting the input from user on button'c click.
The length of each song is greater than 3 minutes.
I've searched the internet and tried multiples solution but no solution is working. Below is the code I've used:
btnDone.setOnClickListener(view.onClickListener)
{
#Override
public void onClick(View view)
{
boolean checked = radioButton1.isChecked();
boolean checked1 = radioButton2.isChecked();
MediaPlayer mediaPlayer = MediaPlayer.create(this,R.raw.song1);
MediaPlayer mediaPlayer2 = MediaPlayer.create(this,R.raw.song2);
if(checked && !checked1)
{
mediaPlayer.start();
}else if(checked1 && !checked)
{
try{
if(mediaPlayer !=null)
{
if(mediaPlayer.isPlaying())
{mediaPlayer.stop;
mediaPlayer.release;
mediaPlayer = null;
}
}
}
catch(Exception e)
{e.printStackTrace(); }
}
}
}
IMO your else if(checked1 && !checked1) condition not working properly so try else if(checked1 && !checked) try below code
btnDone.setOnClickListener(view.onClickListener)
{
#Override
public void onClick(View view)
{
boolean checked = radioButton1.isChecked();
boolean checked1 = radioButton2.isChecked();
MediaPlayer mediaPlayer = MediaPlayer.create(this,R.raw.song1);
MediaPlayer mediaPlayer2 = MediaPlayer.create(this,R.raw.song2);
if(checked && !checked1)
{
mediaPlayer.start();
}else if(checked1 && !checked) //change here
{
try{
if(mediaPlayer !=null)
{
if(mediaPlayer.isPlaying())
{mediaPlayer.stop(); // also change here
mediaPlayer.release(); //change here
mediaPlayer = null;
}
}
}
catch(Exception e)
{e.printStackTrace(); }
}
}
}

Playing just one sound android

i'm developing a little quizz app and i would like to play sound depending on if the user answers the question correctly or not.
I've got many sound files in "assets/".
What I would like to do is to play just one of these sounds.
I've been able to play the sound, but not only one, both sound (correct and incorrect) are played one after the other.
How can i play just one?
Here's my source:
public void audioPlayer(){
//set up MediaPlayer
mp = new MediaPlayer();
try {
String mp3File = "correct.mp3";
AssetManager assetMan = getAssets();
FileInputStream mp3Stream = assetMan.openFd(mp3File).createInputStream();
mp.setDataSource(mp3Stream.getFD());
mp.prepare();
mp.start();
} catch (Exception e) {
e.printStackTrace();
}
}
Put your sound files i.e fail and applause in raw folder and use the following code :
private AssetFileDescriptor sPlaySoundDescriptor = null;
private AssetFileDescriptor sFailSoundDescriptor = null;
private MediaPlayer mp = null;
public static final int FAIL_SOUND = 1;
public static final int APPLAUSE_SOUND = 2;
public void audioPlayer(int soundType){
//set up MediaPlayer
mp = new MediaPlayer();
AssetFileDescriptor soundFileDescriptor = null;
try {
if (sFailSoundDescriptor == null) {
sFailSoundDescriptor = context.getResources().
openRawResourceFd(R.raw.fail);
}
if (sApplauseSoundDescriptor == null) {
sApplauseSoundDescriptor = context.getResources().
openRawResourceFd(R.raw.applause);
}
switch (soundType) {
case FAIL_SOUND:
soundFileDescriptor = sFailSoundDescriptor;
break;
case APPLAUSE_SOUND:
soundFileDescriptor = sApplauseSoundDescriptor;
break;
}
mp.reset();
mp.setDataSource(soundFileDescriptor.getFileDescriptor(),
soundFileDescriptor.getStartOffset(),
soundFileDescriptor.getDeclaredLength());
mp.prepare();
mp.setOnPreparedListener(new OnPreparedListener() {
#Override
public void onPrepared(MediaPlayer player) {
player.seekTo(0);
player.start();
}
});
} catch (Exception e) {
e.printStackTrace();
}
}

Playing audio files one after another

I have a list of audio files like this,
int music_numbers[] = { R.raw.one, R.raw.two, R.raw.three, R.raw.four,
R.raw.five, R.raw.six, R.raw.seven, R.raw.eight, R.raw.nine };
I need to play this one by one - when i send 100 to this play_numbers method - i am intend to play digit wise..
I have done this - but i unable to do this one after another..
private void _play_numbers(final String i) {
// TODO Auto-generated method stub
mPlayer = MediaPlayer.create(PlayFileActivity.this, R.raw.payment);
mPlayer.start();
mPlayer.setOnCompletionListener(new OnCompletionListener() {
#Override
public void onCompletion(MediaPlayer mp) {
// TODO Auto-generated method stub
mPlayer.stop();
myDigit = i.charAt(1) + "";
_function_play_file(Integer.parseInt(myDigit));
}
});
}
in _function_play_file - i have this
void _function_play_file(int files) {
switch (files) {
case 0:
mPlayer = MediaPlayer.create(this, music_numbers[0]);
mPlayer.start();
case 1:
mPlayer = MediaPlayer.create(this, music_numbers[1]);
mPlayer.start();
case 2:
mPlayer = MediaPlayer.create(this, music_numbers[2]);
mPlayer.start();
case 3:
mPlayer = MediaPlayer.create(this, music_numbers[3]);
mPlayer.start();
case 4:
mPlayer = MediaPlayer.create(this, music_numbers[4]);
mPlayer.start();
case 5:
mPlayer = MediaPlayer.create(this, music_numbers[5]);
mPlayer.start();
case 6:
mPlayer = MediaPlayer.create(this, music_numbers[6]);
mPlayer.start();
case 7:
mPlayer = MediaPlayer.create(this, music_numbers[7]);
mPlayer.start();
case 8:
mPlayer = MediaPlayer.create(this, music_numbers[8]);
mPlayer.start();
case 9:
mPlayer = MediaPlayer.create(this, music_numbers[9]);
mPlayer.start();
case 10:
mPlayer = MediaPlayer.create(this, music_numbers[10]);
mPlayer.start();
}
}
You need to set an onCompletionListener to each and start the next one on completion.
mPlayer.setOnCompletionListener(new MediaPlayer.OnCompletionListener()
{
#Override
public void onCompletion(MediaPlayer mp)
{
// Code to start the next audio in the sequence
}
});
The best way to achieve this is to create a class that implements OnCompletionListener which handles the onCompletion and receives the next file to play. This way you can instantiate it nicely in your code.
Of course, don't forget your break; in the cases above.
Use a queue for holding the numbers to be played.
private void _play_numbers(final String i) {
// e.g '100': put '1', '0', '0' in a Queue after converting to digits
Queue queue = new LinkedList();
//Use the add method to add items.
myDigit = // remove next digit from queue..
_function_play_file(myDigit);
}
void _function_play_file(int files) {
switch(files) {
case 0:
mPlayer = MediaPlayer.create(PlayFileActivity.this, R.raw.payment);
mPlayer.setOnCompletionListener(completeListener );
mPlayer.start();
break;
.....
}
OnCompletionListener completeListener = new OnCompletionListener() {
#Override
public void onCompletion(MediaPlayer mp) {
mp.release();
myDigit = // remove next digit from queue..
if (myDigit != -1) // if queue is not empty..
_function_play_file(myDigit);
}
});
}
This code works for me,but i place the audio files in assets folder:
//define a variable to be used as index.
int audioindex = 0;
//Extract the files into an array
String[] files = null;
files = assetManager.list("audiofiles");
mp.setOnCompletionListener(new OnCompletionListener(){
// #Override
public void onCompletion(MediaPlayer arg0) {
// File has ended, play the next one.
FunctionPlayFile(files[audioindex]);
audioindex+=1; //increment the index to get the next audiofile
}
});
This is working code for playing songs in continue loop
public class MainActivity extends Activity
{
private int[] tracks = {R.raw.explosion,R.raw.pianothingy_one,R.raw.car_horn_x};
int mCompleted = 0;
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
MediaPlayer mp = MediaPlayer.create(this, tracks[0]);
mp.setOnCompletionListener(new OnCompletionListener()
{
#Override
public void onCompletion(MediaPlayer mp)
{
mCompleted++;
mp.reset();
if (mCompleted < tracks.length)
{
try
{
AssetFileDescriptor afd = getResources().openRawResourceFd(tracks[mCompleted]);
if (afd != null)
{
mp.setDataSource(afd.getFileDescriptor(), afd.getStartOffset(), afd.getLength());
afd.close();
mp.prepare();
mp.start();
}
}
catch (Exception ex)
{
ex.printStackTrace();
}
}
else if (mCompleted>=tracks.length)
{
mCompleted =0;
try
{
AssetFileDescriptor afd = getResources().openRawResourceFd(tracks[mCompleted]);
if (afd != null)
{
mp.setDataSource(afd.getFileDescriptor(), afd.getStartOffset(), afd.getLength());
afd.close();
mp.prepare();
mp.start();
}
}
catch (Exception ex)
{
ex.printStackTrace();
}
}
else
{
mCompleted=0;
mp.release();
mp = null;
}
}
});
mp.start();
use PlayMedia Like this
int[] soundIDs = {R.raw.yes, R.raw.eat};
PlayMedia playAudio = new PlayMedia(context,soundIDs);
playAudio.execute();
and define PlayMedia Class Like this
import android.content.Context;
import android.media.MediaPlayer;
import android.media.MediaPlayer.OnCompletionListener;
import android.os.AsyncTask;
import android.util.Log;
public class PlayMedia extends AsyncTask<Void, Void, Void> {
private static final String LOG_TAG = PlayMedia.class.getSimpleName();
Context context;
private MediaPlayer mediaPlayer;
int[] soundIDs;
int idx =1;
public PlayMedia(MediaPlayer mediaPlayer) {
this.mediaPlayer = mediaPlayer;
}
public PlayMedia(final Context context, final int[] soundIDs) {
this.context = context;
this.soundIDs=soundIDs;
mediaPlayer = MediaPlayer.create(context,soundIDs[0]);
setNextMediaForMediaPlayer(mediaPlayer);
}
public void setNextMediaForMediaPlayer(MediaPlayer player){
player.setOnCompletionListener(new OnCompletionListener() {
public void onCompletion(MediaPlayer mp) {
if(soundIDs.length>idx){
mp.release();
mp = MediaPlayer.create(context,soundIDs[idx]);
setNextMediaForMediaPlayer(mp);
mp.start();
idx+=1;
}
}
});
}
#Override
protected Void doInBackground(Void... params) {
try {
mediaPlayer.start();
} catch (IllegalArgumentException e) {
Log.e(LOG_TAG, "", e);
} catch (SecurityException e) {
Log.e(LOG_TAG, "", e);
} catch (IllegalStateException e) {
Log.e(LOG_TAG, "", e);
}
return null;
}
}
For me the issue was that I was calling mediaPlayer.prepare() without first calling mediaPlayer.reset().
All good now.
MediaPlayer mediaplayer = new MediaPlayer();
setSound(file );
try {
if(mediaplayer != null)
{
mediaplayer.stop();
mediaplayer.release();
}
mediaplayer.setDataSource(getResources().openRawResourceFd(file)
.getFileDescriptor());
mediaplayer.prepare();
mediaplayer = MediaPlayer.create(getBaseContext(), now);
mediaplayer.start();
mediaplayer.setLooping(false);
mediaplayer.setLooping(true); //sequence playing
} catch (NullPointerException e) {
e.printStackTrace();
}

android : use of media

I want to make application that gives me the list of audio files available in my SDCard and then i should be able to play that audio file from my application. And even pause resume audio playback etc. and function..
Any help on that?
You can see the below code for streaming audio from URL
private void playVideo() {
try {
final String path = "http://www.a1freesoundeffects.com/animals12557/catmeow.wav";
// If the path has not changed, just start the media player
if (path.equals(current) && mp != null) {
mp.start();
return;
}
current = path;
// Create a new media player and set the listeners
mp = new MediaPlayer();
mp.setDataSource(path);
mp.prepare();
mp.setAudioStreamType(AudioManager.STREAM_MUSIC);
} catch (Exception e) {
if (mp != null) {
mp.stop();
mp.release();
}
}
}
You can try this way.
class Mp3Filter implements FilenameFilter {
public boolean accept(File dir, String name) {
return (name.endsWith(".mp3"));
}

playerButton.setOnClickListener(this);
updateSongList();
//demoPlay();
} catch (NullPointerException e) {

}
}
public void updateSongList() {

setListAdapter(songList);
}
}
#Override

playSong(MEDIA_PATH + songs.get(position));
}

mp.reset();
mp.setDataSource(songPath);
mp.prepare();
mp.start();
// Setup listener so next song starts automatically
mp.setOnCompletionListener(new OnCompletionListener() {

nextSong();}
});
} catch(IOException e) {
Log.v(getString(R.string.app_name), e.getMessage());
}
}
private void nextSong() {
if (++currentPosition >= songs.size()) {
// Last song, just reset currentPosition
currentPosition = 0;
// playSong(MEDIA_PATH + songs.get(currentPosition));
} else {
// Play next song
playSong(MEDIA_PATH + songs.get(currentPosition));
}
}
private void demoPause(){
mp.pause();
playerButton.setText(R.string.play_label);

}
}
