If your app requires exact alarms, make sure you handle cases where it no longer has the permission. However, we’re also giving users visibility over the apps that have this permission and letting them grant and revoke it from Special App Access Permissions in Settings. It’s a normal permission, so once you’ve declared it in your manifest, you’ll be automatically granted it at first startup. So in Android 12, we’re making some changes to give users more control.Īpps targeting Android 12 that want to use exact alarms will now need to request a new permission, SCHEDULE_EXACT_ALARM. These are convenient and reliable, but they can also cause battery drain, especially when overused. For cases where you need alarms with precise timing - for example alarm clocks and timers - you can use exact alarms instead. Android manages these alarms to minimize wakeups and battery impacts, such as through Doze and App Standby. In most cases, apps should use inexact alarms, which have the advantage of being battery-friendly. New permission for exact alarms - Alarms are an important way for apps to schedule work. The OS gives CallStyle notifications high visibility, such as bringing them to the top of the notifications shade. You can also attach a large avatar image, provide text, and set button color hints. Each type supports multiple actions, including default actions and custom actions that are specific to your app. You can use the template to create notifications for incoming, outgoing, and screened calls. If your app handles calls - such as a dialer app or chat app with video calling - you’ll want to try our new CallStyle template. In Android 12 we’re improving call notifications to give them more visibility and scannability, and improve their consistency with other notification components. New call notification template - Incoming and ongoing calls are important to users and they need to be easy to see and manage. To customize the experience, check out the new APIs and let us know what you think. We recommend testing your app with the new experience soon, especially if you’re already using a splash screen. There’s nothing you need to do to take advantage of the new experience - it’s enabled by default for all apps. For example, you can use new splashscreen APIs and resources to manage the splash screen window’s background color you can replace the static launcher icon with a custom icon or an animation you can set light mode or dark mode and you can control the timing to reveal the app in the exit animation. The new experience brings standard design elements to every app launch, but we’ve also made it customizable so apps can maintain their unique branding. We’ve added a new app launch animation for all apps from the point of launch, a splash screen showing the app icon, and a transition to the app itself. Improved app launch experience - In Android 12 we’re making app startup a more consistent and delightful experience. Today’s release includes new tools to help you deliver a polished experience and better performance for users.
