| A basic app showing how to display events in the system's notification bar using |
| the NotificationCompat API. |
| NotificationCompat API is used for compatibility with older devices, running Android |
| 1.6 (Donut) (API level 4) or newer. |

| <intro> |
| <![CDATA[ |
| The [Notification API][1] allows the app developers to display a message outside |
| of your application's normal UI. |
| |
| The class [Notification][2] was added in the Android 3.0 (API level 11), but this |
| sample refers to the [NotificationCompat][3] class (part of the [support library][4]), |
| which offers the same functionality for Android 1.6 (API level 4) or newer. |
| |
| A Notificaiton can be created using Notification.Builder object. |
| At bare minimum, a Builder object must include the following: |
| - A small icon, set by [setSmallIcon()][5] |
| - A title, set by [setContentTitle()][6] |
| - Detail text, set by [setContentText()][7] |
| |
| in the code snippet, it looks like following. |
| ```java |
| NotificationCompat.Builder builder = new NotificationCompat.Builder(this); |
| builder.setSmallIcon(R.drawable.ic_stat_notification); |
| builder.setContentTitle("BasicNotifications Sample"); |
| builder.setContentText("Time to learn about notifications!"); |
| ``` |
| |
| To issue the notification, call notify() method in the [NotificationManager][8]. |
| The code snippet will immediately display the notification icon in the |
| notification bar. |
| |
| ```java |
| NotificationManager notificationManager = (NotificationManager) getSystemService( |
| NOTIFICATION_SERVICE); |
| notificationManager.notify(NOTIFICATION_ID, builder.build()); |
| ``` |
