Urban Airship: custom icon for default status bar notification

问题

Urban Airship recommends creating a custom notification with CustomPushNotificationBuilder if you want to make any modifications to the status bar notification, including trivially changing the icon.

Unfortunately, using a RemoteView for notifications carries many unwanted implications with it related to custom manufacturer and/or platform-specific skins, including text colors and references to private resources (for instance @*android:drawable/notify_panel_notification_icon_bg_tile on Honeycomb/ICS).

There must be a simple way to swap the icon without using RemoteView. How?

I found that by overriding BasicPushNotificationBuilder, I can set the icon quite trivially:

BasicPushNotificationBuilder nb = new BasicPushNotificationBuilder() {
    @Override
    public Notification buildNotification(String alert,
            Map<String, String> extras) {
        Notification notification = super.buildNotification(alert,
                extras);
        // The icon displayed in the status bar
        notification.icon = R.drawable.notification;
        // The icon displayed within the notification content
        notification.contentView.setImageViewResource(
                android.R.id.icon, R.drawable.notification);
        return notification;
    }
};
// Set the custom notification builder
PushManager.shared().setNotificationBuilder(nb);

I know this is an old question, but UrbanAirship get's updated quite often, so I decided to help others who might reach this page. As of version 6.0.1 there's no BasicNotificationBuilder no more. In order to customize your notification with icon and color and whatnot, you need to extend the NotifcationFactory class, and override the createNotification method.

Like shown in the example below:

public class MyNotificationFactory extends NotificationFactory {

public MyNotificationFactory(Context context){
    super(context);
}

@Override
public Notification createNotification(PushMessage pushMessage, int i) {
    NotificationCompat.Builder builder = new NotificationCompat.Builder(getContext())
            .setContentTitle(getContext().getResources().getString(R.string.app_name))
            .setContentText(pushMessage.getAlert())
            .setSmallIcon(R.drawable.your_icon_here)
            .setColor(getContext().getResources().getColor(R.color.your_color_here))
            .setAutoCancel(true);

    return builder.build();
}

@Override
public int getNextId(PushMessage pushMessage) {
    return NotificationIDGenerator.nextID();
}

}

At last you must set this as UrbanAirship's new notification factory in your application class or wherever you initialized UA:

UAirship.shared().getPushManager().setNotificationFactory(new MyNotificationFactory(getApplicationContext()));

We provide a lot of functionality in our default notification factory such as big styles (inbox, text, image), lollipop features (privacy, priority), and interactive notification buttons. If you are only trying to set the icon and maybe the accent color, I recommend the following:

    UAirship.takeOff(this, new UAirship.OnReadyCallback() {
        @Override
        public void onAirshipReady(UAirship airship) {
            // Perform any airship configurations here

            // Create a customized default notification factory
            DefaultNotificationFactory defaultNotificationFactory = new DefaultNotificationFactory(getApplicationContext());
            defaultNotificationFactory.setSmallIconId(R.drawable.ic_notification);
            defaultNotificationFactory.setColor(NotificationCompat.COLOR_DEFAULT);

            // Set it
            airship.getPushManager().setNotificationFactory(defaultNotificationFactory);
        }
    });
