In this article, we will go through the improvements that Android12 brings for Exact alarms ⏰.
- To make sure that the effective usage of system resources, Android 12 requires the
“Alarms & reminders”special app access if apps that target Android 12 want to set exact alarms. - SCHEDULE_EXACT_ALARM permission needs to be added in the manifest to get this special app access.
- Exact alarms should only be used for user-facing features. Acceptable use cases
Users or the system can revoke the “Alarms & reminders” special app access. All future exact alarms are canceled when the “Alarms & reminders” special app access is revoked for your app.
- The system sends the
ACTION_SCHEDULE_EXACT_ALARM_PERMISSION_STATE_CHANGEDbroadcast to your app when the “Alarms & reminders” special app access is granted to your app. - It will be sent to both runtime receivers and manifest receivers.
- It will not be sent when the user revokes the permission.
