Android 15 Beta 3 Features: Android 15 Beta 3 has arrived, marking a major milestone in the development of Google’s mobile operating system. The platform has reached stability, meaning that developers can start finalizing their apps for compatibility with Android 15. This article explores the key features and improvements in Android 15 Beta 3, focusing on enhanced security, UI toolkit advancements, AI integration, and the latest AndroidX releases.
Enhanced Security: Passkeys and Beyond
Android 15 Beta 3 introduces passkeys, a passwordless authentication method that enhances security and user convenience. Passkeys leverage biometric authentication, such as facial recognition, fingerprint scanning, or the device’s screen lock, to enable seamless sign-ins to apps. This eliminates the need for remembering complex passwords, reducing the risk of phishing attacks and improving the overall user experience.
Additionally, Android 15 Beta 3 deprecates the web settings database-enabled getter and setter for Web SQL within a WebView. This move aligns with the recommendations of the World Wide Web Consortium and encourages developers to adopt modern web-storage API technologies like IndexedDB, which are more efficient and reliable.
Jetpack Compose: Revolutionizing UI Development
Jetpack Compose, Android’s modern UI toolkit, is proving to be a game-changer for developers. A recent case study highlighted how Max, a leading company, achieved a 30% faster UI implementation by using Jetpack Compose. The framework’s declarative nature, reusable components, and live previews streamline the development process, leading to increased productivity and reduced time-to-market.
| Jetpack Compose Benefits | Description |
| Declarative UI | Describe UI elements and their behavior using Kotlin code. |
| Reusable Components | Build modular UI components that can be easily reused throughout the app. |
| Live Previews | See real-time updates to the UI as you make changes to the code. |
| Simplified State Management | Manage UI state efficiently with built-in state handling mechanisms. |
Google AI Studio: Empowering Developers with AI
Google AI Studio is pushing the boundaries of Android development by integrating artificial intelligence (AI) into the workflow. Recent experiments have demonstrated the potential of AI to transform designs into functional code, fix UI issues, and even add new features based on developer prompts. This opens up exciting possibilities for automating repetitive tasks and accelerating development cycles.

Android Developers Backstage podcast featured an insightful interview with Kathy from Google’s AI Developer Assistance team, where they discussed the integration of Gemini, a powerful AI model, into Android Studio. Gemini’s ability to fine-tune itself for Android development, retrieve information from the internet, and leverage real-time data makes it a valuable asset for developers.
| Google AI Studio Capabilities | Description |
| Design-to-Code Conversion | Generate code from design mockups. |
| UI Issue Fixing | Automatically identify and fix UI issues. |
| Feature Suggestions | Provide intelligent suggestions for new features based on user input. |
| Code Generation | Generate code snippets and templates. |
AndroidX: Stable Releases and Library Updates
AndroidX, the collection of Android support libraries, has seen several stable releases, bringing new features and improvements to various components.
| AndroidX Library | Version | Key Features |
| Glance | 1.1 | Unit testing support, new UI components for home-screen widgets. |
| Fragment | 1.8 | Android Fragment API for embedding fragments in Compose. |
| Lifecycle | 2.8.2 | Fixes for “local Lifecycle owner not present” error with Compose. |
| Core-ktx | 1.6 | Kotlin extensions for Android core components. |
| Espresso | 3.6 | UI testing framework. |
| Camera | 1.3.4 | CameraX library for camera app development. |
Conclusion
Android 15 Beta 3 showcases Google’s commitment to innovation and user-centric design. The introduction of passkeys, advancements in Jetpack Compose, the integration of AI tools, and the stable releases of AndroidX libraries demonstrate the ongoing efforts to enhance security, streamline development, and improve the overall Android experience. As Android 15 moves closer to its final release, developers can look forward to a more powerful, secure, and efficient platform for building the next generation of mobile apps.
