Android behavior

The Android OS differs between an locked and unlocked device.

Locked

The app will only be launched instantly, when your device is in standby.

Unlocked

If your device is not in standby, you will get a default heads up notification with the defined title, text and actionButtons. When you click on it, the app will launch.

HINT
To identify if the app has been launched instantly or by clicking the heads up notification, you can check the property 'isNotificationActive' in the response data of your 'launch' listener. This is true on instant launch.

HINT: Android 14 and above
Starting with Android 14, the full screen intent permission must be granted manually by the user after each update, if the app does not provide calling and alarm functionalities.

FullScreenNotification.addListener('launch', (data) => {
    ...
});

...

await FullScreenNotification.cancelNotification();

Inside the data of the launch event, you can have the following data:

fullScreenId	string	Identifier of the triggering request
isNotificationActive	boolean	Is the notification still active
