通知生成

    private static void generateNotification(Context context, String message) {
            int icon = R.drawable.ic_launcher;
    long when = System.currentTimeMillis();
            NotificationManager notificationManager = (NotificationManager)
                    context.getSystemService(Context.NOTIFICATION_SERVICE);
            Notification notification = new Notification(icon, message, when);

            String title = context.getString(R.string.app_name);

                Intent notificationIntent = new Intent(context, MainActivity.class);
                // set intent so it does not start a new activity
                notificationIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP |
                        Intent.FLAG_ACTIVITY_SINGLE_TOP);
                PendingIntent intent =
                        PendingIntent.getActivity(context, 0, notificationIntent, 0);
                notification.setLatestEventInfo(context, title, message, intent);
                notification.flags |= Notification.FLAG_AUTO_CANCEL;

                // Play default notification sound
                notification.defaults |= Notification.DEFAULT_SOUND;

                //notification.sound = Uri.parse("android.resource://" + context.getPackageName() + "your_sound_file_name.mp3");

                // Vibrate if vibrate is enabled
                notification.defaults |= Notification.DEFAULT_VIBRATE;
                notificationManager.notify(0, notification);      

            }

@Override
    protected void onMessage(Context context, Intent intent) {

        if(aController == null)
            aController = (Controller) getApplicationContext();

        Log.i(TAG, "Received message");
        String message = intent.getExtras().getString("price");

        aController.displayMessageOnScreen(context, message);
        // notifies user
        generateNotification(context, message);
    }

Controller 无效显示消息

       // Notifies UI to display a message.
       void displayMessageOnScreen(Context context, String message) {

            Intent intent = new Intent(Config.DISPLAY_MESSAGE_ACTION);
            intent.putExtra(Config.EXTRA_MESSAGE, message);

            // Send Broadcast to Broadcast receiver with message
            context.sendBroadcast(intent);

        }

它可以注释此 Controller 行。

@Override
    protected void onMessage(Context context, Intent intent) {

        /*if(aController == null)
            aController = (Controller) getApplicationContext();*/

        Log.i(TAG, "Received message");
        String message = intent.getExtras().getString("price");

       // aController.displayMessageOnScreen(context, message);
        // notifies user
        generateNotification(context, message);
    }
