i've solved this issue ,my mistake was imports
import org.greenrobot.eventbus.EventBus;
import org.greenrobot.eventbus.Subscribe;
When I come back after click the back button and I try to play music I have error 'java.lang.IllegalStateException' - but why..? I noticed that others method like player.isPlaying() or player.reset() didn't work too. If somebody had already this problem - please help. Nice day :)

guys i know that passing realm object to another activity is really hard. Anyway i try to do this by service so:
1) MainActivity to job, make realm object and put it safe by use setter in service,
2) service is just like a holder or connection bridge between two activities,
3) in second activity a try to get realm object from service,
Of course i have nullPointerException in get line.
I know that somebody say: hello sqlite is better but i try to understand how realm lib and service can cooperate.
Thats my codes:

I just want to start player when application start automatically without any click. but it display unfortunately stopped with null object reference of Media player. I had never work with service also with music player.
Null pointer exception throws because music service object returns null so.
Finally solved as per #vladMatvienko answer thanks for your support man.
private ServiceConnection musicConnection = new ServiceConnection() {
#Override
public void onServiceConnected(ComponentName name, IBinder service) {
MusicService.MusicBinder binder = (MusicService.MusicBinder) service;
musicSrv = binder.getService();
musicSrv.setList(songList);
musicBound = true;
songPicked();
}
#Override
public void onServiceDisconnected(ComponentName name) {
musicBound = false;
}
};
I am using Sinch and Parse for my instant messaging system integrated in our application, and I have two concerns.
1) For some reason, I am receiving the following error when the messaging activity is displayed: The message client did not start". Furthermore, the message does not seem to go through in Sinch and not reflected visually in the application.
Below is the activity code (when the user clicks on the "quick chat" button, it takes them to the messaging activity page.
Below is the activity code for the messaging activity
public class MessagingActivity extends Activity implements ServiceConnection, MessageClientListener {
private String recipientId;
private Button sendButton;

messageBody = messageBodyField.getText().toString();
if (messageBody.isEmpty()) {
Toast.makeText(this, "Please enter a message", Toast.LENGTH_LONG).show();
return;
}
//Here is where you will actually send the message throught Sinch
messageService.sendMessage(recipientId, messageBody);
messageBodyField.setText("");

I have verified that the APP_KEY, the APP_SECRET and ENVIRONMENT matches what was recorded on Sinch.
I have tried this both on the emulator, and on a physical device.
Thanks in advance

2) Limit: I would like to set a limit, where a only 25 messages would be available between a particular party.
Thanks in advance, and if you need any clarification, let me know.
Update 3
When user clicks on this button, he is taking to the MessagingActivity with the person he has been matched to based upon the below criteria
final Button ibutton = (Button) this.findViewById(R.id.btnQuickChat);
idrinks.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
openConversation();
}
private void openConversation() {
// TODO Auto-generated method stub

query.whereNotEqualTo("objectId", ParseUser.getCurrentUser()
.getObjectId());
query.setLimit(1);
query.findInBackground(new FindCallback<ParseUser>() {
public void done(List<ParseUser> user, ParseException e) {
if (e == null) {
Intent intent = new Intent(getApplicationContext(), MessagingActivity.class);
intent.putExtra("RECIPIENT_ID", user.get(0).getObjectId());
startActivity(intent);
} else {
Toast.makeText(getApplicationContext(),

I wrote the tutorial you're following, and actually just updated it yesterday to fix your first problem. Check out http://tutorial.sinch.com/android-messaging-tutorial/#show-spinner to see the updates. Instead of showing a toast message when the service is not started, the new version will show a progress dialog (loading spinner) until the service has either started or failed to start.
Could you clarify your second question?
Just declare your service in manifest. I had the same problem and it solved it.
