return 1;
}
public void onStart(Intent intent, int startId) {
// TODO
}

player.stop();
player.release();
}
#Override
public void onLowMemory() {
}
}
You should use a service and play the music.
http://developer.android.com/guide/components/services.html
Service runs in the background so even when you switch activities it still runs and you can play your music there.
You can start a service and then stop it when you need. Also you can bind the service to the activity. Look at the docs in the above link for more info.
Example :
https://thenewcircle.com/s/post/60/servicesdemo_using_android_services
import android.app.Service;
import android.content.Intent;
import android.media.MediaPlayer;
import android.os.IBinder;
import android.util.Log;
import android.widget.Toast;
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);
// song is res/raw/yourmusicfile.mp3
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();
}
}
Now just start the service and you can stop the service when you need. You can switch between activities and the service still runs playing the music.
Since the code i huge i uploaded to DropBox. Here's the sample i made

I have created a background service in android in java which plays music at the start of activity.
package com.sudarshan.tictactoenew;
import android.content.Intent;
import android.media.MediaPlayer;
import android.os.IBinder;
import android.app.Service;
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.c);
player.setLooping(true); // Set looping
player.setVolume(100,100);
}
public int onStartCommand(Intent intent, int flags, int startId) {
player.start();
return startId;
}
public void onStart(Intent intent, int startId) {
// TO DO
}
public IBinder onUnBind(Intent arg0) {
// TO DO Auto-generated method
return null;
}
public void onStop() {
}
public void onPause() {
}
#Override
public void onDestroy() {
player.stop();
player.release();
}
#Override
public void onLowMemory() {
}
}
//calling background service
Intent intent = new Intent(MenuPage.this, BackgroundSoundService.class);
startService(intent);
But this runs forever, I mean till the app is not closed.How do I stop this when I move to the next activity?I am calling background service in menupage activity
I am creating an app similar to other audio streaming apps. Is there a way to let a third party player stream music even though the screen of the mobile phone is locked or I am using other application?
You require to create the unbound service to play the media in background while other app may be opened or screen might be lock.
You can refer this for understanding in detail regarding use of services: https://developer.android.com/guide/components/services.html
Like this:
Create Intent first
Intent svc=new Intent(this, BackgroundSoundService.class);
startService(svc);
Create class for the service to run in the background:
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.idil);
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) {
// TO DO
}
public IBinder onUnBind(Intent arg0) {
// TO DO Auto-generated method
return null;
}
public void onStop() {
}
public void onPause() {
}
#Override
public void onDestroy() {
player.stop();
player.release();
}
#Override
public void onLowMemory() {
}
}
Do not forget to call service in manifest file
<service android:enabled="true" android:name=".BackgroundSoundService " />
Hope this helps you.
In my app there is a background music, for what I have a service. It works fine, but it "keeps playing" when either I close the app or turn off the screen.
Should I change something in onPause or onStop?
My code:
public class MyService extends Service {
private 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.id);
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) {
// TO DO
}
public IBinder onUnBind(Intent arg0) {
// TO DO Auto-generated method
return null;
}
protected void onStop() {
player.pause();
}
public void onPause() {
player.pause();
}
#Override
public void onDestroy() {
player.stop();
player.release();
}
#Override
public void onLowMemory() {
}
}
As screen turns off your activity becomes invisible which triggers onPause followed by onStop
Screen on, on the other hand, triggers onStart followed by onResume.
when ever you want to stop service use
stopService(new Intent(ActivityName.this, ServiceClassName.class));
Probably copies of the player are created somehow. Try to make MediaPlayer variable static and then try to deallocate it after pausing onPause(). Anyway it is weird, that you are creating MediaPlayer instance in service.
I've got a service which plays background music in all of my activities, but doesn't turn off while onPause or onStop. I want my music to turn off while apps close or screen turn off, doesnt matter in which activity usesr currently is.
The problem is this:
I have a service. In every activity I coded what to do onPause and onStop. It works fine, but service also stops when I switch to another activity.
Code:
public class MyService extends Service {
private 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.id);
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) {
// TO DO
}
public IBinder onUnBind(Intent arg0) {
// TO DO Auto-generated method
return null;
}
protected void onStop() {
player.pause();
}
public void onPause() {
player.pause();
}
#Override
public void onDestroy() {
player.stop();
player.release();
}
#Override
public void onLowMemory() {
}
}
You will have to stop the service in the onDestroy method of your main activity. Check this answer
I have an Android application that plays streamed audio from the Internet using the MediaPlayer class.
How do I let it continue to play the audio on the background when the
user hits the home button to run other applications?
While running other apps, I'd like it to continue to play the audio.
You have to use something called Android Services.
From the docs:
"A Service is an application component representing either an application's desire to perform a longer-running operation while not interacting with the user or to supply functionality for other applications to use."
Here's the excellent official guide to using services to get you started:
http://developer.android.com/guide/components/services.html
Here's a good tutorial on building an audio player:
http://www.androidhive.info/2012/03/android-building-audio-player-tutorial/
Here's a video tutorial for building a streaming music player:
http://www.youtube.com/watch?v=LKL-efbiIAM
You'll need to implement a Service in order to play media in the background without it being tied to the Activity that started playback. Have a look at this example.
The key is define Service.START_STICKY to continue playing in background:
public int onStartCommand(Intent intent, int flags, int startId) {
myMediaPlayer.start();
return Service.START_STICKY;
}
Service.START_STICKY : if this service's process is killed while it is
started the system will try to re-create the service.
This is an example of to do this:
import android.app.Service;
import android.content.Intent;
import android.media.MediaPlayer;
import android.os.IBinder;
import android.util.Log;
import android.widget.Toast;
/**
* Created by jorgesys.
*/
/* Add declaration of this service into the AndroidManifest.xml inside application tag*/
public class BackgroundSoundService extends Service {
private static final String TAG = "BackgroundSoundService";
MediaPlayer player;
public IBinder onBind(Intent arg0) {
Log.i(TAG, "onBind()" );
return null;
}
#Override
public void onCreate() {
super.onCreate();
player = MediaPlayer.create(this, R.raw.jorgesys_song);
player.setLooping(true); // Set looping
player.setVolume(100,100);
Toast.makeText(this, "Service started...", Toast.LENGTH_SHORT).show();
Log.i(TAG, "onCreate() , service started...");
}
public int onStartCommand(Intent intent, int flags, int startId) {
player.start();
return Service.START_STICKY;
}
public IBinder onUnBind(Intent arg0) {
Log.i(TAG, "onUnBind()");
return null;
}
public void onStop() {
Log.i(TAG, "onStop()");
}
public void onPause() {
Log.i(TAG, "onPause()");
}
#Override
public void onDestroy() {
player.stop();
player.release();
Toast.makeText(this, "Service stopped...", Toast.LENGTH_SHORT).show();
Log.i(TAG, "onCreate() , service stopped...");
}
#Override
public void onLowMemory() {
Log.i(TAG, "onLowMemory()");
}
}
Start service:
Intent myService = new Intent(MainActivity.this, BackgroundSoundService.class);
startService(myService);
Stop service:
Intent myService = new Intent(MainActivity.this, BackgroundSoundService.class);
stopService(myService);
Complete code of this example.
