If you have disabled OneSignal’s default notification open behavior, please see the section below to ensure your custom handling meets the requirements. For apps using the default OneSignal notification setup, no additional changes are required after updating the SDK. The OneSignal-Android-SDK 4.5.0 has been optimized to show the user visual feedback even faster. How to Migrate Away From a Notification Trampoline Providing prompt user feedback is therefore important to capture audience engagement in addition to creating a positive UX. To complicate this experience further, notifications disappear immediately after they're opened, so the user will not be given another opportunity to launch the app.

For your users, this additional computing time translates to an unresponsive notification, which can negatively impact their app experience and hurt brand perception. How does a notification trampoline affect UX?Ī notification trampoline introduces a delay that can range from well under a second to many seconds or more if the background work is intensive or requires a network call to finish.

This intermediary thread often takes additional time to compute before the intended app Activity is displayed to the user. Some apps use a "notification trampoline" technique to call a background Service or Broadcast when a notification is tapped before launching an app Activity. One significant notification change associated with Android 12 is that notification trampolines have been disallowed. With the release of Android 12 this week, we wanted to revisit these notification changes and share how we've adapted our Android SDK to optimize performance and compliance. We shared our thoughts and perspectives on Mobile Push in Android 12 earlier this year when the Beta was released and initial features were announced.
