I'm trying to use service for a background music.
package com.example.neotavraham;
import android.app.Service;
import android.content.Intent;
import android.media.MediaPlayer;
import android.os.IBinder;
import android.util.Log;
public class PlayMusicService extends Service implements MediaPlayer.OnPreparedListener {
public static final String ACTION_PLAY = "com.example.neotavraham.PLAY";
MediaPlayer mMediaPlayer = null;
#Override
public int onStartCommand(Intent intent, int flags, int startId) {
if (intent.getAction().equals(ACTION_PLAY)) {
mMediaPlayer = MediaPlayer.create(this, R.raw.yedid_nefesh);
mMediaPlayer.setOnPreparedListener(this);
mMediaPlayer.prepareAsync(); // prepare async to not block main thread
}
return flags;
}
#Override
public void onPrepared(MediaPlayer mp) {
mp.start();
}
#Override
public IBinder onBind(Intent intent) {
return null;
}
}
I call it from the MainActivity with the line: startService(new Intent(PlayMusicService.ACTION_PLAY));
and of course I added an intent-filter
<intent-filter>
<action android:name="com.example.neotavraham.PLAY"/>
</intent-filter>
I was looking for a fine solution in the internet but couldn't find one...what should I do?
Please call the service from intent and set the action of that intent like this:
Intent i = new Intent(this,PlayMusicService.class);
i.setAction("com.example.neotavraham.PLAY");
startService(i);
This code will work.
Background service for start media player
package com.example.neotavraham;
import android.app.Service;
import android.content.Intent;
import android.media.MediaPlayer;
import android.os.IBinder;
import android.util.Log;
public class PlayMusicService extends Service {
public static final String ACTION_PLAY = "com.example.neotavraham.PLAY";
MediaPlayer mMediaPlayer = null;
#Override
public int onStartCommand(Intent intent, int flags, int startId) {
if (intent.getAction().equals(ACTION_PLAY)) {
mMediaPlayer = MediaPlayer.create(this, R.raw.idil);
mMediaPlayer.setLooping(true); // Set looping
mMediaPlayer.setVolume(100,100);
mMediaPlayer.start();
}
return flags;
}
#Override
public IBinder onBind(Intent intent) {
return null;
}
#Override
public void onDestroy() {
mMediaPlayer.stop();
mMediaPlayer.release();
}
}
Thanks
In your activity do the following:
Intent i = new Intent(this,PlayMusicService.class);
i.putExtra("action","com.example.neotavraham.PLAY");
startService(i);
In your service do the following:
package com.example.neotavraham;
import android.app.Service;
import android.content.Intent;
import android.media.MediaPlayer;
import android.os.IBinder;
import android.util.Log;
public class PlayMusicService extends Service {
public static final String ACTION_PLAY = "com.example.neotavraham.PLAY";
MediaPlayer mMediaPlayer = null;
#Override
public int onStartCommand(Intent intent, int flags, int startId) {
if (intent.getStringExtra("action").equals(ACTION_PLAY)) {
mMediaPlayer = MediaPlayer.create(this, R.raw.yedid_nefesh);
mMediaPlayer = MediaPlayer.create(this, R.raw.idil);
mMediaPlayer.setLooping(true); // Set looping
mMediaPlayer.setVolume(100,100);
mMediaPlayer.start();
}
return flags;
}
#Override
public IBinder onBind(Intent intent) {
return null;
}
#Override
public void onDestroy() {
mMediaPlayer.stop();
mMediaPlayer.release();
}
}
In your manifiest do the following:
<service
android:name="com.example.neotavraham.PlayMusicService"
/>
This is the perfect code for your app. Hope this will work finally....

I'm trying to make a simple musicPlayer that works on Android device.To make Background-play come true, I'm using Service class.
What I want to do is below:
1.User launches app and taps start button
2.Music starts and Notification that notes the Music is playing appears
3.User taps home button and the app's UI disappears
4.Music doesn't stop
5.User tap Notification
6.UI appears with disabled start button and enabled stop button ← I'm in trouble
With My Code, UI appears. But it is not the UI which user made to disappear. How do I describe...It is new-ed UI.
So when user taps stop button,of course music doesn't stop. The Service is different one.
I want music to stop.
Is there any way to show the first created UI? the original UI?
If there's no way to show first created UI,how can I reach to first running service?
Thank you for browsing.

I have other activities and I want the music to be heard when my application is opened, but when it goes to background, I don't want music to continue playing. I tried with BaseActivityClass and have read a lot, but still no solution. Please help, thank you in advance.
When you are done using MediaPlayer you need to release it with the release() method. I guess the onDestroy() method of you Service is a good place for that:
public class BackgroundMusic extends Service {
private static final String TAG = null;
public MediaPlayer player;
public IBinder onBind(Intent arg0) {
return null;
}
#Override
public void onCreate() {
super.onCreate();
player = MediaPlayer.create(this, R.raw.background);
player.setLooping(true); // Set looping
player.setVolume(100,100);
}
public int onStartCommand(Intent intent, int flags, int startId) {
player.start();
return START_STICKY;
}
public int onDestroy() {
player.release();
}
}
I have created a Service in my android application which starts running on BOOT_COMPLETE. I want to run my Service non-stop (run always), and for that I have used while(true) inside onStartCommand() method. So is this fine to use while(true) or there is any other better way to run a service always in background?
This is code of my Service:
package com.example.abc.project1;
import android.app.Service;
import android.content.Intent;
import android.os.IBinder;
import org.json.*;
import java.io.*;
import java.net.*;
import java.util.*;
public class HelloService extends Service {
private static final String TAG = "HelloService";
private boolean isRunning = false;
#Override
public IBinder onBind(Intent arg0) {
return null;
}
#Override
public void onCreate() {
super.onCreate();
isRunning = true;
}
#Override
public int onStartCommand(Intent intent, int flags, int startId) {
new Thread(new Runnable() {
#Override
public void run() {
while(true) {
/*non-stop work to be done in background always*/
}
}
}).start();
return Service.START_STICKY;
}
#Override
public void onDestroy() {
isRunning = false;
}
}
I have not tried this myself but if you change receiver to service it should work.
m using service to play a audio file in background.

My PreviewServices is working fine,
in My Activity i want to show a message when my song will complete.
m using this code for this purpose.
PreviewServices preview=new PreviewServices();
MusicScreen.this.preview.player.setOnCompletionListener(new OnCompletionListener() {
public void onCompletion(MediaPlayer mp) {
// TODO Auto-generated method stub
Log.d("song is complete","song complete");
}
});
I dont know Y its throws Null Pointer Exception in this line
MusicScreen.this.preview.player.setOnCompletionListener(new OnCompletionListener()
please suggest me where is problem.
thanks in advance.

I'm sure you'll get more responses if your code is displayed properly. Every line of code needs to have four spaces or a tab at the start of it. Try editing to fix it.
A simple thing you can do is break up the line like this (where you specify appropriate classes for x, y and z):
x = MusicScreen.this
y = x.preview
z = y.player
z.setOnCompletionListener(ETC.
Then you can see where it breaks down. Other than that, I don't understand your program so I can't help...
