Foreground Usage Example

Question

I am new to android. Can someone post a link or code for "an example of using an Android application with a notification". I googled but got no foreground example.

Answer 1

Create a Notification , possibly using Notification.Builder or NotificationCompat.Builder , and pass this value to startForeground() in the service:

 public class Downloader extends IntentService { private static int FOREGROUND_ID=1338; public Downloader() { super("Downloader"); } @Override public void onHandleIntent(Intent i) { startForeground(FOREGROUND_ID, buildForegroundNotification(filename)); // do useful work here stopForeground(true); } private Notification buildForegroundNotification(String filename) { NotificationCompat.Builder b=new NotificationCompat.Builder(this); b.setOngoing(true); b.setContentTitle(getString(R.string.downloading)) .setContentText(filename) .setSmallIcon(android.R.drawable.stat_sys_download) .setTicker(getString(R.string.downloading)); return(b.build()); } } 

(cropped service from this sample project )

Answer 2

The best example:

 @Override public int onStartCommand(Intent intent, int flags, int startId) { if (intent.getAction().equals(Constants.ACTION.STARTFOREGROUND_ACTION)) { Log.i(LOG_TAG, "Received Start Foreground Intent "); Intent notificationIntent = new Intent(this, MainActivity.class); notificationIntent.setAction(Constants.ACTION.MAIN_ACTION); notificationIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TASK); PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, notificationIntent, 0); Intent previousIntent = new Intent(this, ForegroundService.class); previousIntent.setAction(Constants.ACTION.PREV_ACTION); PendingIntent ppreviousIntent = PendingIntent.getService(this, 0, previousIntent, 0); Intent playIntent = new Intent(this, ForegroundService.class); playIntent.setAction(Constants.ACTION.PLAY_ACTION); PendingIntent pplayIntent = PendingIntent.getService(this, 0, playIntent, 0); Intent nextIntent = new Intent(this, ForegroundService.class); nextIntent.setAction(Constants.ACTION.NEXT_ACTION); PendingIntent pnextIntent = PendingIntent.getService(this, 0, nextIntent, 0); Bitmap icon = BitmapFactory.decodeResource(getResources(), R.drawable.truiton_short); Notification notification = new NotificationCompat.Builder(this) .setContentTitle("Truiton Music Player") .setTicker("Truiton Music Player") .setContentText("My Music") .setSmallIcon(R.drawable.ic_launcher) .setLargeIcon( Bitmap.createScaledBitmap(icon, 128, 128, false)) .setContentIntent(pendingIntent) .setOngoing(true) .addAction(android.R.drawable.ic_media_previous, "Previous", ppreviousIntent) .addAction(android.R.drawable.ic_media_play, "Play", pplayIntent) .addAction(android.R.drawable.ic_media_next, "Next", pnextIntent).build(); startForeground(Constants.NOTIFICATION_ID.FOREGROUND_SERVICE, notification); } else if (intent.getAction().equals(Constants.ACTION.PREV_ACTION)) { Log.i(LOG_TAG, "Clicked Previous"); } else if (intent.getAction().equals(Constants.ACTION.PLAY_ACTION)) { Log.i(LOG_TAG, "Clicked Play"); } else if (intent.getAction().equals(Constants.ACTION.NEXT_ACTION)) { Log.i(LOG_TAG, "Clicked Next"); } else if (intent.getAction().equals( Constants.ACTION.STOPFOREGROUND_ACTION)) { Log.i(LOG_TAG, "Received Stop Foreground Intent"); stopForeground(true); stopSelf(); } return START_STICKY; }
