Android on Tizen

Tizen 9.0 Features – Android on Tizen

Technical Overview
Android on Tizen (AoT) is an innovative technology that enables Android applications to run on the Tizen platform. With this solution, users can enjoy Android apps on Tizen devices without modification, providing a seamless experience across platforms.

Seamless User Experience
AoT integrates graphics, multimedia, connectivity, and app execution between the Tizen host and Android container, creating a unified environment that feels like a single OS to end users.

Broad Device Compatibility
To support diverse Tizen devices using different SoCs and kernel versions, the Android container was modularized. Hardware-dependent components were isolated, and kernel-specific features were implemented in userland to ensure compatibility with both v4 and v5 kernels.

Verified on Multiple Target Devices
AoT has been successfully deployed on devices such as Raspberry Pi 4 (RPI4), VIM3, and FHUB. These deployments have verified the core functionality and performance, showcasing the technology’s scalability and adaptability.

Optimized Graphics and Multimedia Performance
AoT allows direct GPU access and supports hardware codecs within the container to achieve high-performance graphics and multimedia processing, resulting in near-native rendering capabilities.

Integrated App Installation and Launch
Android application installation and launching are integrated with Tizen’s package manager and app launcher, enabling users to install and run Android apps without switching contexts or environments.

Memory Footprint Optimization
AoT applies various memory optimization techniques to reduce idle memory usage. Currently, the container uses approximately 328MB when idle — a significant improvement over the 500MB required in earlier VD AoT containers.

Ensured System Stability
To validate the reliability of AoT, Android CTS (Compatibility Test Suite) is utilized. Tailored CTS modules for Tizen achieved a high pass rate of about 99%, ensuring system robustness.
