I implemented everything I've found here, but my service is not starting yet.
What I need to do is to start playing a radio station when the user clicks on a button, and only stop it when he clicks it again. I don't want the radio to be stopped if the application get closed.
When I test the code I'm sending, nothing happens.
Manifest:
<service
android:name=".RadioService"
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:exported="false"
>
</service>
Service Code:
package com.po.portelaonline.service;
import android.app.Service;
import android.content.Intent;
import android.os.IBinder;
public class RadioService extends Service {
Player player;
#Override
public int onStartCommand(Intent intent, int flags, int startId) {
player.start();
return Service.START_NOT_STICKY;
}
#Override
public void onCreate(){
player = new Player();
}
#Override
public IBinder onBind(Intent arg0) {
// TODO Auto-generated method stub
return null;
}
#Override
public void onDestroy(){
player.stopThread();
}
}
Player class code:
package com.po.portelaonline.service;
import android.media.MediaPlayer;
import android.media.MediaPlayer.OnPreparedListener;
import com.po.portelaonline.classes.Util;
class Player extends Thread {
volatile boolean running = true;
#Override
public void run() {
MediaPlayer player = new MediaPlayer();
try {
player.setDataSource(Util.getRadioUrl());
player.setOnPreparedListener(oplPlayer);
player.prepareAsync();
while (running) {
Player.sleep(500);
}
player.release();
player = null;
} catch (Exception e) {
e.printStackTrace();
}
}
public void stopThread() {
running = false;
}
OnPreparedListener oplPlayer = new OnPreparedListener() {
#Override
public void onPrepared(MediaPlayer mp) {
mp.start();
}
};
}
And I'm calling this way:
Intent i = new Intent(getApplicationContext(), RadioService.class);
if(getApplicationContext().startService(i) == null){
findViewById(R.id.btnPlayStop).setBackgroundDrawable(getApplicationContext().getResources().getDrawable(R.drawable.stop));
}else{
getApplicationContext().stopService(i);
findViewById(R.id.btnPlayStop).setBackgroundDrawable(getApplicationContext().getResources().getDrawable(R.drawable.play));
}
Try this code for service class.
You don't need to create MediaPlayer object in separate thread. player.prepareAsync(); is already asynchronous.
EDIT:
The path to the RadioService class into the AndroidManifest.xml should be absolute: android:name="com.po.portelaonline.service.RadioService"
public class RadioService extends Service implements OnPreparedListener, OnErrorListener{
MediaPlayer mPlayer;
#Override
public int onStartCommand(Intent intent, int flags, int startId) {
startPlayer();
return Service.START_NOT_STICKY;
}
#Override
public void onCreate(){
initMediaPlayer();
}
private void initMediaPlayer () {
mPlayer = new MediaPlayer();
mPlayer.setOnPreparedListener(this);
mPlayer.setOnErrorListener(this);
mPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
mPlayer.setWakeMode(getApplicationContext(),
PowerManager.PARTIAL_WAKE_LOCK);
}
private void startPlayer(){
player.setDataSource(Util.getRadioUrl());
player.prepareAsync();
}
#Override
public IBinder onBind(Intent arg0) {
// TODO Auto-generated method stub
return null;
}
#Override
public void onDestroy(){
mPlayer.release();
}
#Override
public void onPrepared (MediaPlayer mp) {
mp.start();
}
#Override
public boolean onError (MediaPlayer mp, int what, int extra) {
Log.e("RadioService OnError", "what="+what+" extra="+extra);
return false;
}
}
i guess it should be
if(getApplicationContext().startService(i) != null)
instead of if(getApplicationContext().startService(i) == null)
You are immediately stopping the service after you start it.

I'm using the BackGroundSound service music, but when I press the homebutton or power button or exiting the app the music just doesn't stop, and I need it to stop, Anyone have any suggestions/ideas how to fix it? I used this guide https://www.simplifiedcoding.net/android-service-example/
public class Backgroundsoundservice extends Service {
private static final String TAG = null;
MediaPlayer player;
public IBinder onBind(Intent arg0) {
return null;
}
#Override
public void onCreate() {
super.onCreate();
player = MediaPlayer.create(this, R.raw.backgroundmusic01);
player.setLooping(true); // Set looping
player.setVolume(100,100);
}
#SuppressLint("WrongConstant")
public int onStartCommand(Intent intent, int flags, int startId) {
player.start();
return 1;
}
public void onStart(Intent intent, int startId) {
// TO DO
}
public IBinder onUnBind(Intent arg0) {
// TO DO Auto-generated method
return null;
}
public void onStop() {
player.stop();
}
public void onPause()
{
player.pause();
}
#Override
public void onDestroy() {
player.stop();
player.release();
}
#Override
public void onLowMemory() {
}
}
Try overriding onPause like this.
#Override
protected void onPause() {
super.onPause();
if (mediaPlayer != null){
mediaPlayser.stop();
if (isFinishing()){
mediaPlayer.stop();
mediaPlayer.release();
}
}
}
I created a game.I added some background music to the app and now I want to pause the music when the app is exited using home button and the song should resume when it is opened from the multitasking.
package tssll8.coloursmash;
import android.app.Service;
import android.content.Intent;
import android.media.MediaPlayer;
Import android.os.IBinder;
/**

public IBinder onBind(Intent arg0) {

}
#Override
public void onCreate() {
super.onCreate();

player.setLooping(true); // Set looping
player.setVolume(100,100);
}
public int onStartCommand(Intent intent, int flags, int startId) {
player.start();
return 1;
}
public void onStart(Intent intent, int startId) {

}
Mediaplayer has a pause() method: MediaPlayer#pause()
so you could call that in the on pause which gets triggered by pressing the home button, like so
public void onPause() {
player.pause();
}
and resume it in onResume like this:
public void onResume() {
player.play();
}
I have been working on a media player and tried to integrate a seek bar, I used a Bind service to code the MediaPlayer functions and called those function in my Activity using the reference of that bind service, I used a Handler to assist the runnable, However, my seekBar is unable to track the progress of playing media.
The code for tracking SeekBar is as follows:-
Runnable runnable=new Runnable() {
#Override
public void run() {
seekUpdate();
}
};
public void seekUpdate(){
seekBar.setProgress(service.currentPosition());
handler.postDelayed(runnable,1000);
}
#Override
public void onProgressChanged(SeekBar seekBar, int progress, boolean fromUser) {
service.seekTo(progress);
}
#Override
public void onStartTrackingTouch(SeekBar seekBar) {
}
#Override
public void onStopTrackingTouch(SeekBar seekBar) {
}
And the Code from my Bind Service Class(Where MediaPlayer functions have been integrated) is as follows:-
package com.daman.mediaplayer;
import android.app.Service;
import android.content.Intent;
import android.media.MediaPlayer;
import android.os.Binder;
import android.os.IBinder;
import android.support.annotation.IntDef;

mediaPlayer = new MediaPlayer();
songToPlay = intent.getStringExtra("keySong");
songPath=intent.getStringExtra("songpath");
try {
mediaPlayer.setDataSource(songPath);
//mediaPlayer.setDataSource(this, Uri.parse(url));
} catch (IOException e) {
e.printStackTrace();
}
try {
mediaPlayer.prepare();
} catch (IOException e) {
e.printStackTrace();
}
return ibRef;
}
#Override
public boolean onUnbind(Intent intent) {
return super.onUnbind(intent);
}
public void playMusic(){
mediaPlayer.start();
}
public void pauseMusic(){
mediaPlayer.pause();
}
public void stopMusic(){
mediaPlayer.stop();
mediaPlayer.release();
}
public int currentPosition(){

}
public void seekTo(int position){
mediaPlayer.seekTo(position);
}
class MyBinder extends Binder{
BindMusicService getServiceReference(){

}
}
}
When i play and pause the media the error that pops in android monitor is :-

I did a small simulation of background music play on Android, but it doesnt work... there's the code:
[my activity, in onCreate]
Intent music = new Intent(this, MusicService.class);
startService(music);
[and there's the class MusicService]
public class MusicService extends Service implements MediaPlayer.OnErrorListener {
private final IBinder mBinder = new ServiceBinder();
MediaPlayer mPlayer;
private int length = 0;
public class ServiceBinder extends Binder {
MusicService getService()
{
return MusicService.this;
}
}
#Override
public IBinder onBind(Intent arg0){
return mBinder;
}
#Override
public void onCreate () {
super.onCreate();
mPlayer = MediaPlayer.create(this, R.raw.song1);
mPlayer.setOnErrorListener(this);
if(mPlayer!= null)
{
mPlayer.setLooping(true);
mPlayer.setVolume(100,100);
}
mPlayer.setOnErrorListener(new OnErrorListener() {
public boolean onError(MediaPlayer mp, int what, int extra){
onError(mPlayer, what, extra);
return true;
}
});
}
#Override
public int onStartCommand (Intent intent, int flags, int startId)
{
mPlayer.start();
return START_STICKY;
}
public void pauseMusic()
{
if(mPlayer.isPlaying())
{
mPlayer.pause();
length=mPlayer.getCurrentPosition();
}
}
public void resumeMusic()
{
if(mPlayer.isPlaying()==false)
{
mPlayer.seekTo(length);
mPlayer.start();
}
}
public void stopMusic()
{
mPlayer.stop();
mPlayer.release();
mPlayer = null;
}
#Override
public void onDestroy ()
{
super.onDestroy();
if(mPlayer != null)
{
try{
mPlayer.stop();
mPlayer.release();
}
finally {
mPlayer = null;
}
}
}
public boolean onError(MediaPlayer mp, int what, int extra) {
Toast.makeText(this, "music player failed", Toast.LENGTH_SHORT).show();
if(mPlayer != null)
{
try{
mPlayer.stop();
mPlayer.release();
}
finally {
mPlayer = null;
}
}
return false;
}
}
I can't hear any song in the emulator. I did complete the Manifest file like this:
<service
android:name="MusicService"
android:enabled="true">
</service>
Is there something else to add to the Manifest, is there a problem with my code or with my emulator?
Thank you!
I am shearing my code on background music play on Android. It will be solve your problem.
I head created two classes first one is MainActivity and second one is MyService.
MainActivity code is
public class MainActivity extends Activity implements OnClickListener {
private static final String TAG = "MainActivity";
Button play, stop;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
play = (Button) findViewById(R.id.play);
stop = (Button) findViewById(R.id.stop);
play.setOnClickListener(this);
stop.setOnClickListener(this);
}
#Override
public void onClick(View src) {
switch (src.getId()) {
case R.id.play:
Log.d(TAG, "onClick: starting srvice");
startService(new Intent(this, MyService.class));
break;
case R.id.stop:
Log.d(TAG, "onClick: stopping srvice");
stopService(new Intent(this, MyService.class));
break;
}
}
}
Now the MyService code is
public class MyService extends Service {
private static final String TAG = "MyService";
MediaPlayer player;
#Override
public IBinder onBind(Intent intent) {
return null;
}
#Override
public void onCreate() {
Toast.makeText(this, "My Service Created", Toast.LENGTH_LONG).show();
Log.d(TAG, "onCreate");
player = MediaPlayer.create(this, R.raw.braincandy);
player.setLooping(false); // Set looping
}
#Override
public void onDestroy() {
Toast.makeText(this, "My Service Stopped", Toast.LENGTH_LONG).show();
Log.d(TAG, "onDestroy");
player.stop();
}
#Override
public void onStart(Intent intent, int startid) {
Toast.makeText(this, "My Service Started", Toast.LENGTH_LONG).show();
Log.d(TAG, "onStart");
player.start();
}
}
U have to create a "raw" folder in your "res" folder than paste your music file in that raw folder.
I'm creating a mediaplayer service to play a media file from internet, like this:
public class MyService extends Service{
private static final String TAG = "MyService";
MediaPlayer mediaPlayer;
#Override
public IBinder onBind(Intent intent) {
return null;
}
#Override
public void onCreate() {
Toast.makeText(this, "My Service Created", Toast.LENGTH_LONG).show();
Log.d(TAG, "onCreate");
mediaPlayer = new MediaPlayer();
mediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
}
#Override
public void onDestroy() {
Toast.makeText(this, "My Service Stopped", Toast.LENGTH_LONG).show();
Log.d(TAG, "onDestroy");
mediaPlayer.stop();
}
#Override
public void onStart(Intent intent, int startid) {
Toast.makeText(this, "My Service Started", Toast.LENGTH_LONG).show();
Log.d(TAG, "onStart");
String rtsp;
Bundle re= intent.getExtras();
rtsp=re.getString("rtsp");
try {
mediaPlayer.setDataSource(rtsp);
mediaPlayer.prepare();
} catch (IllegalArgumentException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IllegalStateException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
mediaPlayer.start();
}
}
Now I want to get the seekbar from the activity like this:
SeekBar seekbar= (SeekBar)findviewbyid(R.id.seekbar);
But I can't :( Please help me how to do that!
EDIT
I found another way to solve my problem without using Bind service :)
Here it is:
In your service class, create a static method like this:
public static void setMainActivity(Player_Activity mainActivity)
{
MAIN_ACTIVITY=mainActivity;
}
Ofcourse, you must declare a static varible:
private static Player_Activity MAIN_ACTIVITY;
Next, in your activity, before you call the startService(), you must call this method to set the main activity to your service like this:
MyService.setMainActivity(Player_Activity.this);
Intent myservice= new Intent(this,MyService.class);
startService(myservice);
And finally you can do anything with your activity in your service like this:
final TextView tv_test=(TextView)MAIN_ACTIVITY.findViewById(R.id.textview);
That's all! Hope this help :)
Forgive me if I get some mistake about English ;), my English skill is not good :)
I know that it has been already answered. But I tried the below code which worked for me.May be useful for someone.
public class MediaPlayerService extends Service implements MediaPlayer.OnPreparedListener,MediaPlayer.OnCompletionListener{
String ExactPath;
int total,CurrentPosition;
MediaPlayer mp;
private final IBinder mBinder=new LocalBinder();
public class LocalBinder extends Binder {
MediaPlayerService getService(){
return MediaPlayerService.this;
}
}
#Override
public IBinder onBind(Intent intent) {
return mBinder;
}
#Override
public void onCreate() {
mp=new MediaPlayer();
mp.setAudioStreamType(AudioManager.STREAM_MUSIC);
mp.setOnPreparedListener(this);
}
#Override
public int onStartCommand(Intent intent, int flags, int startId) {
ExactPath=intent.getStringExtra("pos");
PrepareMediaPlayer();
if(!mp.isPlaying()){
mp.start();
}else{
mp.pause();
}
return START_STICKY;
}
public void PrepareMediaPlayer(){
try {
mp.setDataSource(ExactPath);
mp.prepareAsync();
} catch (IOException e) {
e.printStackTrace();
}catch (IllegalStateException e){ }
catch(IllegalFormatException e){ }
}
#Override
public void onPrepared(MediaPlayer mediaPlayer) {
mp.start();
}
#Override
public void onCompletion(MediaPlayer mediaPlayer) {
stopSelf();
}
public int seekBarGetCurrentPosition(){ //This method is created to get SongCurrentPosition from mediaplayer for seekbar
if(mp!=null&&mp.isPlaying()){
CurrentPosition=mp.getCurrentPosition();
}
return CurrentPosition;
}
#Override
public void onDestroy() {
if(mp.isPlaying()){
mp.stop();
}
mp.release();
}
}
Note:In service class I had issue in getting MediaPlayer duration. I am not getting correct result when my activity requests duration from service. So I have implemented a method which gets the duration right from the activity. Hope you can fix duration in service itself. But this code worked for me.
Then in your Activity, after onCreate() method.
/**The below method songDuration() is created as substitution for getMediaPlayerDuration() method
* if getMediaPlayerDuration() failed to get the duration from mediaPlayer via service this method
* helps to avoid returning zero or null value . Because it has been observed that service takes
* quite a long time to return a value, if it is called frequently with in a span of seconds say, pressing
* Next button continuously.
*/
public int songDuration(){
MediaMetadataRetriever mmr=new MediaMetadataRetriever();
mmr.setDataSource(path);
String Dur=mmr.extractMetadata(MediaMetadataRetriever.METADATA_KEY_DURATION);
Integer Duration=Integer.parseInt(Dur);
return Duration;
}
#Override

You are playing media in service so to communicate with service you have to bind activity with service.
