How to create a notification with NotificationCompat.Builder?

Solution
The NotificationCompat.Builder is the most easy way to create `Notifications` on all Android versions. You can even use features that are available with Android 4.1. If your app runs on devices with Android >=4.1 the new features will be used, if run on Android <4.1 the notification will be an simple old notification.
To create a simple Notification just do (see Android API Guide on Notifications):
NotificationCompat.Builder mBuilder =
new NotificationCompat.Builder(this)
.setSmallIcon(R.drawable.notification_icon)
.setContentTitle("My notification")
.setContentText("Hello World!")
.setContentIntent(pendingIntent); //Required on Gingerbread and below
You have to set at least `smallIcon`, `contentTitle` and `contentText`. If you miss one the Notification will not show.
Beware: On Gingerbread and below you have to set the content intent, otherwise a `IllegalArgumentException` will be thrown.
To create an intent that does nothing, use:
final Intent emptyIntent = new Intent();
PendingIntent pendingIntent = PendingIntent.getActivity(ctx, NOT_USED, emptyIntent, PendingIntent.FLAG_UPDATE_CURRENT);
You can add sound through the builder, i.e. a sound from the RingtoneManager:
mBuilder.setSound(RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION))
The Notification is added to the bar through the NotificationManager:
NotificationManager notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.notify(mId, mBuilder.build());
Problem
I need to create a simple notification which will be shown in notification bar along with the sound and icon if possible? I also need it to be compatitible with Android 2.2, so i found that NotificationCompat.Builder works with all APIs above 4. If there's a better solution, feel free to mention it.
