Install and run your apps faster than with a physical device and simulate different configurations and features, including ARCore, Google's platform for building augmented reality experiences. Powered by Gradle, Android Studio's build system allows you to customize your build to generate multiple build variants for different devices from a single project. The built-in profiling tools provide realtime statistics for your app's CPU, memory, and network activity.

Identify performance bottlenecks by recording method traces, inspecting the heap and allocations, and see incoming and outgoing network payloads.
