How to put media controller button on notification bar?

Question

I am creating a music player application. I want to show the media controller on notification bar while my application is running in background. It looks like Google player.

How to do this?

Here is the example above done correctly to the new API

In your main, when you want to start a notification instantiate the class:

NotificationPanel nPanel = new NotificationPanel(MyActivity); 

And when you want to cancel notification: (as it is an onGoing notification)

nPanel.notificationCancel();     

Then create the class for the notification caller:

public class NotificationPanel {  private Context parent; private NotificationManager nManager; private NotificationCompat.Builder nBuilder; private RemoteViews remoteView;  public NotificationPanel(Context parent) {     // TODO Auto-generated constructor stub     this.parent = parent;     nBuilder = new NotificationCompat.Builder(parent)     .setContentTitle("Parking Meter")     .setSmallIcon(R.drawable.ic_launcher)     .setOngoing(true);      remoteView = new RemoteViews(parent.getPackageName(), R.layout.notificationview);      //set the button listeners     setListeners(remoteView);     nBuilder.setContent(remoteView);      nManager = (NotificationManager) parent.getSystemService(Context.NOTIFICATION_SERVICE);     nManager.notify(2, nBuilder.build()); }  public void setListeners(RemoteViews view){     //listener 1     Intent volume = new Intent(parent,NotificationReturnSlot.class);     volume.putExtra("DO", "volume");     PendingIntent btn1 = PendingIntent.getActivity(parent, 0, volume, 0);     view.setOnClickPendingIntent(R.id.btn1, btn1);      //listener 2     Intent stop = new Intent(parent, NotificationReturnSlot.class);     stop.putExtra("DO", "stop");     PendingIntent btn2 = PendingIntent.getActivity(parent, 1, stop, 0);     view.setOnClickPendingIntent(R.id.btn2, btn2); }  public void notificationCancel() {     nManager.cancel(2); } }     

Then add the return class that accept the pending intent:

public class NotificationReturnSlot extends Activity {  @Override protected void onCreate(Bundle savedInstanceState) {     // TODO Auto-generated method stub     super.onCreate(savedInstanceState);     String action = (String) getIntent().getExtras().get("DO");     if (action.equals("volume")) {         Log.i("NotificationReturnSlot", "volume");         //Your code      } else if (action.equals("stopNotification")) {          //Your code         Log.i("NotificationReturnSlot", "stopNotification");      }      finish();     } } 

Then you need to make a XML file for the button. This is a simple one:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="horizontal" >  <Button     android:id="@+id/btn1"     android:layout_width="wrap_content"     android:layout_height="wrap_content"     android:layout_margin="10dp"     android:text="volume" />  <Button     android:id="@+id/btn2"     android:layout_width="wrap_content"     android:layout_height="wrap_content"     android:layout_margin="10dp"     android:text="Stop" />  <TextView     android:id="@+id/message"     android:layout_width="wrap_content"     android:layout_height="wrap_content"     android:layout_toRightOf="@+id/msglbl" /> 

Last and not least, the Manifest file:

   <activity android:name=".NotificationReturnSlot"         android:launchMode="singleTask"         android:taskAffinity=""         android:excludeFromRecents="true"/>
