weird android mediaplayer error - Error (-38,0)? - android

I m having a weird error! A few minutes ago there were no errors then I cleaned up the project and suddenly an error! I recently removed an error : FATAL EXCEPTION: main; Error receiving broadcast Intent ! by commenting
//seekIntent.putExtra("song_ended", "1");
//sendBroadcast(seekIntent);
in myPlayService();
Error :

The problem seems to be that you call reset() before calling isPlaying() here:
mp.reset();
if (!mp.isPlaying()) {
according the MediaPlayer documentation after calling reset() the MediaPlayer will move into its uninitialized "idle" state. Then calling isPlaying() on an uninitialized state MediaPlayer will then throw an IllegalStateException.
==> After resetting the Mediaplayer you will need to initialize / prepare it again before you can start it again

please help me in fixing this issues..
Thank you in advance..
In your onStop() of your activity stop and release the media player.
Place the below code in your onStop():
#Override
public void onStop() {
super.onStop();
if(media != null){
media.stop(); //Stops playback after playback has been stopped or paused
media.release(); //Releases resources associated with this MediaPlayer object
media = null;
}
if(mediaPlayer!= null){
mediaPlayer.stop();
mediaPlayer.release();
mediaPlayer= null;
}
}
This is the proper way to stop media player.
Hope it helps:)

Trying to create simple audio player app in android using android studio, but its not working.

Main portions of code :
// This is event handler for buttonClick event
void buttonClick(){
if (buttonPlayStop.getText() == getString(R.string.play_str)) {
buttonPlayStop.setText(getString(R.string.pause_str));
try{
mediaPlayer.start();
startPlayProgressUpdater();
}catch (IllegalStateException e) {
if(mediaPlayer.isPlaying()) {
mediaPlayer.pause();
}
mediaPlayer.pause();
mediaPlayer.seekTo(0);
}
}else {
buttonPlayStop.setText(getString(R.string.play_str));
mediaPlayer.pause();
}
These where the errors, pause called in state 8 error (-38, 0) Error (-38,0) start called in state 0 error (-38, 0) Error (-38,0) and the song is not playing.
Media Player has its own life-cycle when you are calling its functions make sure that you are in correct state of the media player
Best method to do is make a media player service and bind to that service in your activity and maintain all media player methods in that service.
http://examples.javacodegeeks.com/android/android-mediaplayer-example/
add these in your player activity
public MusicService musicSrv ;
private boolean musicBound=false;
private ArrayList<Song> songList;
inside oncreate
songList = new ArrayList<Song>();
getSongList();
add this in your actitivity
#Override
protected void onStart() {
super.onStart();
if(playIntent==null){
playIntent = new Intent(this, MusicService.class);
this.bindService(playIntent, musicConnection, Context.BIND_AUTO_CREATE);
this.startService(playIntent);
}
}
private ServiceConnection musicConnection = new ServiceConnection(){
#Override
public void onServiceConnected(ComponentName name, IBinder service) {
MusicService.MusicBinder binder = (MusicService.MusicBinder)service;
//get service
musicSrv = binder.getService();
//pass list
musicSrv.setList(songList);
musicBound = true;
songTitleLabel.setText(""+musicSrv.getSongTitle());
}
#Override
public void onServiceDisconnected(ComponentName name) {
musicBound = false;
}
};
public void getSongList(){
ContentResolver musicResolver = getContentResolver();
Uri musicUri = android.provider.MediaStore.Audio.Media.EXTERNAL_CONTENT_URI;
Cursor musicCursor = musicResolver.query(musicUri, null, null, null, null);
if(musicCursor!=null && musicCursor.moveToFirst()){
int titleColumn = musicCursor.getColumnIndex
(android.provider.MediaStore.Audio.Media.TITLE);
int idColumn = musicCursor.getColumnIndex
(android.provider.MediaStore.Audio.Media._ID);
int artistColumn = musicCursor.getColumnIndex
(android.provider.MediaStore.Audio.Media.ARTIST);
do {
long thisId = musicCursor.getLong(idColumn);
String thisTitle = musicCursor.getString(titleColumn);
String thisArtist = musicCursor.getString(artistColumn);
songList.add(new Song(thisId, thisTitle, thisArtist));
}
while (musicCursor.moveToNext());
}
}
add list in to your activity and in list item click
if(musicSrv.isPlaying()){
if(musicSrv.status()!=null){
musicSrv.pauseSong();
btnPlay.setImageResource(R.drawable.btn_play);
}
}else{
if(musicSrv.status()!=null){
musicSrv.restartSong();
btnPlay.setImageResource(R.drawable.btn_pause);
}
}
add this as a service in your app

}
and these in your manifest
service android:name=".Services.MusicService"
inside application tag
use theses permissions
<uses-permission android:name="android.permission.WAKE_LOCK" />
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.READ_PHONE_STATE" />
hope this will work for you !

Passing data to a service in Android

I'm trying to create a Service that will play a music in the background in Android.
But I get an NPE while the service is starting.
Could anyone tell me what I'm doing wrong?

Can anyone tell me what I'm doing wrong?
First, that's not an NPE (null pointer exception).
Second, you are calling your playMedia method entirely too often. Considering that it calls MediaPlayer.prepare, it doesn't make sense in several of the places I see it being called. In particular, you are calling it in the onPrepared callback. The MediaPlayer's state machine is giving you an IllegalStateException because you can't call prepare from the prepared state. You should also not call prepare from the onCompletion callback. The MediaPlayer has a strict state machine and you should probably pay more attention to it.

I have 2 activities. I need to play one background music to all the activities.I want play and stop song from main activity

you need a Service which is independent to the activity to play the song
public class SongService extends Service {
MediaPlayer mm;
#Override
public IBinder onBind(Intent intent) {
// TODO Auto-generated method stub
return null;
}
#Override
public void onCreate() {
// TODO Auto-generated method stub
super.onCreate();
mm = MediaPlayer.create(this, R.raw.mainmenu2);
mm.setLooping(true);
}
#Override
public void onDestroy() {
// TODO Auto-generated method stub
super.onDestroy();
mm.stop();
}
#Override
public void onStart(Intent intent, int startId) {
// TODO Auto-generated method stub
super.onStart(intent, startId);
mm.start();
}
}
then add this whenever you want to play the song in the service.
startService(new Intent(this, SongService.class));
and to finish it add this:
stopService(new Intent(MainMenu.this,SongService.class));
So when you press the button start the service, and whenever you press the stop button stop it. this is how you can play songs through activities.
First you have to create a raw folder in res folder and paste the song you want to play there.
MainActivity,java======
protected void onCreate(){
MediaPlayer backgroundSong;
backgroundSong = MediaPlayer.create(MainActivity.this, R.raw.your_song_name);
backgroundSong.start();}
#Override
protected void stopSong() {
// TODO Auto-generated method stub
backgroundSong.release();
}
OtherActivity.java
protected void onPause(){
MainActivity ma = new MainActivity();
ma.stopSong();
}

First issue:
In the thread "run" method, in the while condition you are saying:
(currentPosition<total)
this way "currentPosition" value will never reach "total" value and your progressbar won't go, you should use "less than or equal":
(currentPosition<=total)
so code will be:
public void run() {
int currentPosition= 0;
int total = mp.getDuration();
while (mp!=null && mp.isPlaying() && currentPosition<=total) {
try {
Thread.sleep(1000);
currentPosition= mp.getCurrentPosition();
} catch (InterruptedException e) {
return;
} catch (Exception e) {
return;
}
progressBar.setProgress(currentPosition);
}
}
Second issue:
You can change the ImageButton using "mp.setOnCompletionListener(this)" like this:
mp.setOnCompletionListener(new OnCompletionListener() {
public void onCompletion(MediaPlayer mp) {
pauseicon.setImageResource(R.drawable.playicon);
}
});
Set it while initializing the mediaplayer, before mp.start()
