Android 5.0 provides a faster, smoother and more powerful computing experience.

Android now runs exclusively on the new ART runtime, built from the ground up to support a mix of ahead-of-time (AOT), just-in-time (JIT), and interpreted code. It’s truly cross-platform and is supported on ARM, x86, and MIPS architectures. It is also fully 64-bit compatible.

Android now runs exclusively on the new ART runtime, built from the ground up to support a mix of ahead-of-time (AOT), just-in-time (JIT), and interpreted code. It’s supported on ARM, x86, and MIPS architectures and is fully 64-bit compatible.

ART improves app performance and responsiveness. Efficient garbage collection reduces the number and duration of pauses for GC events, which fit comfortably within the v-sync window so your app doesn’t skip frames. ART also dynamically moves memory to optimize performance for foreground uses.

Android 5.0 introduces platform support for 64-bit architectures—used by the Nexus 9's NVIDIA Tegra K1. Optimizations provide larger address space and improved performance for certain compute workloads. Apps written in the Java language run as 64-bit apps automatically—no modifications are needed. If your app uses native code, we’ve extended the NDK to support new ABIs for ARM v8, and x86-64, and MIPS-64.

Continuing the focus on smoother performance, Android 5.0 offers improved A/V sync. The audio and graphics pipelines have been instrumented for more accurate timestamps, enabling +video apps and games to display smooth synchronized content.

Enhanced Camera & Video

-

Android 5.0 introduces all new camera APIs that let you capture raw formats such as YUV and Bayer RAW, and control parameters such as exposure time, ISO sensitivity, and frame duration on a per-frame basis. The new fully-synchronized camera pipeline allows you to capture uncompressed 8 megapixel YUV images at 30 FPS on supported devices.

Along with images, you can also capture metadata like noise models and optical information from the camera.

A new dumpsys batterystats command generates battery usage statistics that you can use to understand system-wide power use and understand the impact of your app on the device battery. You can look at a history of power events, approximate power use per UID and system component, and more.

Battery Historian is a new tool to convert the statistics from dumpsys batterystats into a visualization for battery-related debugging. You can find it at https://github.com/google/battery-historian.
