Its entirely up to you.\n\n## Customising the appearance of a Push Notification\n\nTo customise the appearance or content of a notification, implement as many `NotificationCompat.Extender`s as you like, and add them to Sailthru Mobile's `NotificationConfig`.\n\nNote that if any extenders are added, they will by default override Carnival’s notification extender. If you’d like us to still do our default notification extension, you can manually re-extend using `CarnivalNotificationExtender`\n\nFor example, if we wanted to change the title of push notifications with the custom field `special_price`, we could implement the following `NotificationCompat.Extender`:\n[block:code]\n{\n  \"codes\": [\n    {\n      \"code\": \"class SaleNotificationExtender implements NotificationCompat.Extender {\\n    \\n  :::at:::Override\\n  public NotificationCompat.Builder extend(NotificationCompat.Builder builder) {\\n    Bundle bundle = builder.getExtras();\\n    Context context = builder.mContext;\\n    if(bundle.containsKey(\\\"special_price\\\")) {\\n      builder.setContentTitle(\\\"SALE\\\")\\n        .setContentText(bundle.getString(\\\"alert\\\"));\\n    } else {\\n      return builder.extend(new CarnivalNotificationExtender());\\n    }\\n\\n    return builder;\\n  }\\n}\",\n      \"language\": \"java\"\n    }\n  ]\n}\n[/block]\nThen add it to our `NotificationConfig`:\n[block:code]\n{\n  \"codes\": [\n    {\n      \"code\": \" public class MyApplication extends Application {\\n   @Override\\n   public void onCreate() {\\n     super.onCreate();\\n\\n     Carnival.startEngine(getApplicationContext(), \\\"your sdk key\\\");\\n\\n     NotificationConfig notificationConfig = new NotificationConfig();\\n     notificationConfig.addNotificationExtender(new SaleNotificationExtender());\\n     Carnival.setNotificationConfig(notificationConfig);\\n   }\\n }\",\n      \"language\": \"java\"\n    }\n  ]\n}\n[/block]\n\n[block:callout]\n{\n  \"type\": \"success\",\n  \"body\": \"Having access to the `NotificationCompat.Builder` means you can change pretty much whatever you like about the style and content of the notification. Check out the official [Android Notification documentation](http://developer.android.com/guide/topics/ui/notifiers/notifications.html).\"\n}\n[/block]\n\n[block:callout]\n{\n  \"type\": \"danger\",\n  \"body\": \"Please don't set a `PendingIntent` using `setContentIntent` directly, as it's defined by Sailthru Mobile so we can track opens properly. If you want to change the `Intent` to be executed when a notification is tapped, check the next section.\"\n}\n[/block]\n## Customising the action to be executed when a notification is tapped\n\nTo direct users to an activity of your choosing, you can implement a `ContentIntentBuilder` and set it using `NotificationConfig`.\n[block:callout]\n{\n  \"type\": \"warning\",\n  \"body\": \"Note that this `ContentIntentBuilder` will not be called when the notitication has a deep-link attached.\"\n}\n[/block]\nTo extend the previous example, if we wanted to direct users to some activity `SaleActivity` when a notification has the custom field `special_price` defined we could create a new class implementing `ContentIntentBuilder`:\n[block:code]\n{\n  \"codes\": [\n    {\n      \"code\": \"import com.carnival.sdk.ContentIntentBuilder;\\n    \\npublic class SaleContentIntentBuilder implements ContentIntentBuilder {\\n  @Nullable\\n  @Override\\n  public PendingIntent build(Context context, Bundle bundle) {\\n    if(bundle.containsKey(\\\"special_price\\\")) {\\n      Intent intent = new Intent(context, SaleActivity.class);\\n      return PendingIntent.getActivity(context, 12345, intent, PendingIntent.FLAG_UPDATE_CURRENT);\\n    }\\n\\n    // return null to keep the default behavior\\n    return null;\\n  }\\n}\",\n      \"language\": \"java\"\n    }\n  ]\n}\n[/block]\nThen, like last time, add an instance to `NotificationConfig`:\n[block:code]\n{\n  \"codes\": [\n    {\n      \"code\": \"public class MyApplication extends Application {\\n  @Override\\n  public void onCreate() {\\n    super.onCreate();\\n\\n    Carnival.startEngine(getApplicationContext(), \\\"your sdk key\\\");\\n\\n    NotificationConfig notificationConfig = new NotificationConfig();\\n    notificationConfig.addNotificationExtender(new SaleNotificationExtender());\\n    notificationConfig.setContentIntentBuilder(new SaleContentIntentBuilder());\\n    Carnival.setNotificationConfig(notificationConfig);\\n  }\\n}\",\n      \"language\": \"java\"\n    }\n  ]\n}\n[/block]\n## Listening to Received Notifications or Tapped Notifications\n\nIt's easy to listen on when a notification was received, and when a user has tapped the notification.\n\n* To listen for received notifications implement `NotificationReceivedListener` and add your listener using `Carnival.addNotificationReceivedListener`.\n* To listen for tapped notifications implement `NotificationTappedListener` and add your listener using `Carnival.addNotificationReceivedListener`.\n\nFor example, if we wanted to log when we got notifications with the custom field 'special_price' present, we could implement a received and a tapped listener:\n[block:code]\n{\n  \"codes\": [\n    {\n      \"code\": \"public class MyNotificationReceivedListener implements NotificationReceivedListener {\\n  private static final String TAG = \\\"NotificationLogger\\\";\\n  @Override\\n  public void onNotificationReceived(Context context, Bundle bundle) {\\n    if(bundle.containsKey(\\\"special_price\\\")) {\\n      Log.i(TAG, \\\"Sale Notification received\\\");\\n    }\\n  }\\n}\\n    \\npublic class MyNotificationTappedListener implements NotificationTappedListener {\\n  @Override\\n  public void onNotificationTapped(Context context, Bundle bundle) {\\n    if(bundle.containsKey(\\\"special_price\\\")) {\\n      Log.i(TAG, \\\"Sale Notification tapped! That's a good push!\\\");\\n    }\\n  }\\n}\",\n      \"language\": \"java\"\n    }\n  ]\n}\n[/block]\nThen add these to `Carnival`\n[block:code]\n{\n  \"codes\": [\n    {\n      \"code\": \"public class MyApplication extends Application {\\n    \\n  @Override\\n  public void onCreate() {\\n    super.onCreate();\\n\\n    Carnival.startEngine(getApplicationContext(), \\\"your sdk key\\\");\\n\\n    Carnival.addNotificationReceivedListener(new MyNotificationReceivedListener());\\n    Carnival.addNotificationTappedListener(new MyNotificationTappedListener());\\n  }\\n}\",\n      \"language\": \"java\"\n    }\n  ]\n}\n[/block]\n\n[block:callout]\n{\n  \"type\": \"info\",\n  \"body\": \"These listeners will be called for all notifications, including deep link notifications using `_u`.\"\n}\n[/block]\n## Silent Push Notifications\n\nImplement `NotificationSilencer` if you want to suppress any received notification from the user\n\n-  You can silence notifications from other providers\n-  or Receive a notification to start a special background service using a `NotificationReceivedListener`\n\n \nExample of usage to silence notifications when the custom key `silent` is present.\n[block:code]\n{\n  \"codes\": [\n    {\n      \"code\": \"class MyNotificationSilencer implements NotificationSilencer {\\n  @Override\\n  boolean isSilent(Context context, Bundle bundle) {\\n    return bundle.containsKey(\\\"silent\\\");\\n  }\\n}\",\n      \"language\": \"java\"\n    }\n  ]\n}\n[/block]\nAdd your implementation using `notificationConfig.setSilencer(NotificationSilencer)`\n[block:code]\n{\n  \"codes\": [\n    {\n      \"code\": \"public class MyApplication extends Application {\\n    \\n  @Override\\n  public void onCreate() {\\n    super.onCreate();\\n\\n    Carnival.startEngine(getApplicationContext(), \\\"your sdk key\\\");\\n    NotificationConfig notificationConfig = new NotificationConfig();\\n    notificationConfig.setSilencer(new MyNotificationSilencer());\\n    Carnival.setNotificationConfig(notificationConfig);\\n\\n  }\\n}\",\n      \"language\": \"java\"\n    }\n  ]\n}\n[/block]\n## Bundle Data\n\nOn all customisations available the Bundle will contain all data that was attached to the push and can be used in building your notification.\n[block:image]\n{\n  \"images\": [\n    {\n      \"image\": [\n        \"https://files.readme.io/258db45-image_16.png\",\n        \"image_16.png\",\n        570,\n        376,\n        \"#e4ecf3\"\n      ]\n    }\n  ]\n}\n[/block]\nThe above push notification would result in a bundle containing the following data:\n[block:code]\n{\n  \"codes\": [\n    {\n      \"code\": \"{\\n  \\\"alert\\\": \\\"<push message>\\\", \\n  \\\"badge\\\": \\\"5\\\", \\n  \\\"sound\\\": \\\"<sound name>\\\", \\n  \\\"<custom key>\\\": \\\"<custom value>\\\"\\n}\",\n      \"language\": \"json\"\n    }\n  ]\n}\n[/block]","excerpt":"Overriding Sailthru Mobile's default behaviour","slug":"android-custom-notification-handling","type":"basic","title":"Android: Notification Handling"}
