title: NotificationCompat in Android gingerbread doesn't work
body: <p>I used to read <a href="https://stackoverflow.com/questions/20032249/is-setcontentintentpendingintent-required-in-notificationcompat-builder">this topic about NotificationCompat</a> and I know that the contentIntent is required on Gingerbread and below. However, I'm working in android Gingerbread and I don't want to add PendingIntent. What should I do to have the correct notification?<br/> 
  Thanks for your help </p>
  
  <pre><code>NotificationCompat.Builder builder = new NotificationCompat.Builder(this);
      builder.setAutoCancel(true);
      builder.setContentTitle("Basic notification");
      builder.setContentText(content);
      builder.setSmallIcon(R.drawable.ic_launcher);
  
      Notification notification = builder.build();
      try {
          NotificationManager manager = (NotificationManager) this
                  .getSystemService(NOTIFICATION_SERVICE);
  
          manager.notify(8, notification);
      } catch (Exception e) {
          Log.i("Exception", e.getMessage()); 
      }
  </code></pre>
  
  <p><b> Exception : contentIntent required: pkg=com.example.notificationtutorial id=8 notification=Notification(vibrate=null,sound=null,defaults=0x0,flags=0x10)</b></p>
