New Delhi: Google has released the fourth beta of its upcoming Android 12 operating system that offers several new consumer-focused capabilities for the developers to work on, including Game Mode, AppSearch, new notification style for phone calls and others. The Game Mode allows developers to optimise gameplay by prioritizing characteristics, such as performance or battery life based on users settings or game specific configurations. Android 12 introduces AppSearch, a high-performance on-device search engine, as a system service. "AppSearch allows applications to index structured data and search over it with built-in full-text search capabilities," according to a Google update. Furthermore, AppSearch supports native search features, like highly-efficient indexing and retrieval, multi-language support and relevancy ranking.

"Android 12 introduces a new app launch animation for all apps that includes an into-app motion from the point of launch, a splash screen showing the app icon, and a transition to the app itself," Google said. Android 12 also adds the new notification style for phone calls. Using this template lets the app indicate the importance of active calls by displaying a prominent chip that shows the time of the call in the status bar; the user can tap this chip to return to their call. "In Android 12, you can now enrich your app's notification experience by providing animated images in notifications. Also, your app can now enable users to send image messages when they reply to messages from the notification shade," said Google.
