Installation

There are 2 ways to install the Notification Scheduler plugin into your project:

• search for and select the Android Notification Scheduler plugin in Godot Editor
• click Download button
• on the installation dialog...
  • keep Change Install Folder setting pointing to your project's root directory
  • keep Ignore asset root checkbox checked
  • click Install button
• enable the plugin via the Plugins tab of Project->Project Settings... menu, in the Godot Editor

Installing manually

Steps:

• download release archive from Github
• unzip the release archive
• copy to your Godot project's root directory
• enable the plugin via the Plugins tab of Project->Project Settings... menu, in the Godot Editor

Notification icon

Copy your notification icon to your Godot 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

Generating notification icons using Android Studio

Steps:

• Open your Godot project's android/build directory in Android Studio
• Wait for it to fully load
• Right click on res folder and select New -> Image Asset from the context menu
• On the Asset Studio wizard
  • Set Icon type to Notification Icons
  • Enter a the name of your notification icon (ie. ic_my_notification)
  • Configure your icon
  • Click Next button
  • Click Finish button to confirm
• The following new directories should have been created under your Godot project's android/build/res directory:
  • drawable-anydpi
  • drawable-xxhdpi
  • drawable-xhdpi
  • drawable-hdpi
  • drawable-mdpi
• Make sure you use the name you specified for your icons when initializing notifications:
  • my_notification_data.set_small_icon_name("<your_notification_icon_name_here>")

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)
