In case it helps anyone    I was having a lot of trouble with setting up notifications using the support package when testing against newer an older API s  I was able to get them to work on the newer device but would get an error testing on the old device  What finally got it working for me was to delete all the imports related to the notification functions  In particular the NotificationCompat and the TaskStackBuilder  It seems that while setting up my code in the beginning the imports where added from the newer build and not from the support package  Then when I wanted to implement these items later in eclipse  I wasn t prompted to import them again  Hope that makes sense  and that it helps someone else out

This is in API 11  so if you are developing for anything earlier than 3 0 you should continue to use the old API   Update  the NotificationCompat Builder class has been added to the Support Package so we can use this to support API level v4 and up   http   developer android com reference android support v4 app NotificationCompat Builder html

UPDATE android-N  march-2016   Please visit Notifications Updates link for more details    Direct Reply Bundled Notifications Custom Views      Android N also allows you to bundle similar notifications to appear as   a single notification  To make this possible  Android N uses the   existing NotificationCompat Builder setGroup   method  Users can   expand each of the notifications  and perform actions such as reply   and dismiss on each of the notifications  individually from the   notification shade       This is a pre-existing sample which shows a simple service that sends   notifications using NotificationCompat  Each unread conversation from   a user is sent as a distinct notification       This sample has been updated to take advantage of new notification   features available in Android N    sample code

I was having a problem building notifications  only developing for Android 4 0     This link showed me exactly what I was doing wrong and says the following   Required notification contents  A Notification object must contain the following   A small icon  set by setSmallIcon   A title  set by setContentTitle   Detail text  set by setContentText     Basically I was missing one of these  Just as a basis for troubleshooting with this  make sure you have all of these at the very least  Hopefully this will save someone else a headache

It works even in API 8 you can use this code    Notification n       new Notification R drawable yourownpicturehere  getString R string noticeMe    System currentTimeMillis      PendingIntent i PendingIntent getActivity this  0               new Intent this  NotifyActivity class                                  0   n setLatestEventInfo getApplicationContext    getString R string title   getString R string message   i   n number   count  n flags    Notification FLAG AUTO CANCEL  n flags    Notification DEFAULT SOUND  n flags    Notification DEFAULT VIBRATE  n ledARGB   0xff0000ff  n flags    Notification FLAG SHOW LIGHTS      Now invoke the Notification Service String notifService   Context NOTIFICATION SERVICE  NotificationManager mgr        NotificationManager  getSystemService notifService   mgr notify NOTIFICATION ID  n     Or I suggest to follow an excellent tutorial about this

Notification Builder is strictly for Android API Level 11 and above  Android 3 0 and up    Hence  if you are not targeting Honeycomb tablets  you should not be using the Notification Builder but rather follow older notification creation methods like the following example
