Notification icon

Copy your notification icon to your project's android/build/res directory.

Alternatively, you could use Android Studio's Image Asset Studio to generate your icon set.

Note: the notification icon resource should be of type drawable

Usage

Add a NotificationScheduler node to your scene and follow the following steps:

Register listeners for the following signals emitted from the NotificationScheduler node
- notification_opened - when user taps notification item
- permission_granted
- permission_denied
At startup, using the NotificationScheduler node to check that the application has permissions to post notifications:

	$NotificationScheduler.has_post_notifications_permission()

If the application doesn't have permissions to post notifications, then request permission using the NotificationScheduler node:

	$NotificationScheduler.request_post_notifications_permission()

permission_granted signal will be emitted when the application receives the permissions

On Android, apps that target Android 13 or higher can ask for notification permission as many times as they want until the user explicitly denies the permission twice. If the user targets Android 12 or lower, the app can ask for permission as many times as it wants until the user denies the permission once. If the user denies the permission twice, the app can't ask again unless the user reinstalls the app

After user has denied the request, you can ask to turn on notification permission manually and send them to App_Info screen using the NotificationScheduler node:(Best Practice: Don't promt users automatically, insted keep a button in settings to toggle notifications)

	$NotificationScheduler.open_app_info_settings()

Create a notification channel using the NotificationScheduler node:

	$NotificationScheduler.create_notification_channel(
		NotificationChannel.new()
			.set_id("my_channel_id")
			.set_name("My Channel Name")
			.set_description("My channel description")
			.set_importance(NotificationChannel.Importance.DEFAULT))

Build NotificationData object:

	var my_notification_data = NotificationData.new()
	my_notification_data.set_id(__notification_id).\
			set_channel_id("my_channel_id").\
			set_title("My Notification Title").\
			set_content("My notification content").\
			set_small_icon_name("ic_name_of_the_icon_that_you_generated").\
			set_delay(my_delay_in_seconds)

Schedule notification using the NotificationScheduler node:

	$NotificationScheduler.schedule(
			my_notification_data
		)

NotificationData's set_interval(interval_in_seconds) method can be used for scheduling repeating notifications.
NotificationData's set_deeplink(data) method can be used for delivering URI data along with the notification.
- The Deeplink Plugin can then be used to process the URI data.

Other Available Methods

cancel(notification_id)
get_notification_id() - alternative way to get the ID of the last opened notification.

Demo

Restore the following notification icons after Android Build Template is installed for the demo app.
- demo/android/build/res/drawable-anydpi-v24/ic_demo_notification.xml
- demo/android/build/res/drawable-hdpi/ic_demo_notification.png
- demo/android/build/res/drawable-mdpi/ic_demo_notification.png
- demo/android/build/res/drawable-xhdpi/ic_demo_notification.png
- demo/android/build/res/drawable-xxhdpi/ic_demo_notification.png

Troubleshooting

ADB logcat

adb logcat is one of the best tools for troubleshooting unexpected behavior

use $> adb logcat | grep 'godot' on Linux
- adb logcat *:W to see warnings and errors
- adb logcat *:E to see only errors
- adb logcat | grep 'godot|somethingElse' to filter using more than one string at the same time
use #> adb.exe logcat | select-string "godot" on powershell (Windows)
