+# Enable push notifications
 Push notifications let clients be notified for incoming messages and other operations occurring in a chat thread in situations where the mobile app isn't running in the foreground. Azure Communication Services supports a [list of events that you can subscribe to](../concepts/chat/concepts.md#push-notifications).
 > [!NOTE]
 > Chat push notifications are supported for Android SDK in versions starting from 1.1.0-beta.4 and 1.1.0. It is recommended that you use version 1.2.0 or newer, as older versions have a known issue with the registration renewal. Steps from 8 to 12 are only needed for versions equal to or greater than 1.2.0.
