Customising notifications for Android

The default notification color is defined in android/build/res/values/notification-color.xml. You can change it at your desire. The color string format is #RRGGBB.

In order to change default notification icon you should make this new files:

android/build/res/mipmap/notification_icon.png            Size 192x192
android/build/res/mipmap-hdpi-v4/notification_icon.png    Size 72x72
android/build/res/mipmap-mdpi-v4/notification_icon.png    Size 48x48
android/build/res/mipmap-xhdpi-v4/notification_icon.png   Size 96x96
android/build/res/mipmap-xxhdpi-v4/notification_icon.png  Size 144x144
android/build/res/mipmap-xxxhdpi-v4/notification_icon.png Size 192x192

Notification icons should be b/w with alpha channel. They will be tinted with color which we discuss above.

Use push notifications for iOS

1. check if notifications is_inited, it means that application requested permissions from user.
2. call init if app didn’t requested it yet.
3. catch signal enabled or check method is_enabled. It will return false if user didn’t grant you permission.
4. get device token (get_device_token) for push notifications or catch signal device_token_received
5. send your device token to the server side.

That’s all. Sending notifications processed by your server, receiving notifications processed by OS.

Troubleshooting

If the notification doesn't appear, make sure you're not trying to display it while your game is in the foreground. In iOS, apps can only show notifications if they are in the background. This implies that you must use interval > 0.
