In their own words
Android Emulator
Android Emulator simulates Android devices on a computer so developers can test applications across device types and Android API levels without a physical device. It comes with Android Studio and needs no separate installation. Predefined virtual-device profiles cover phones, tablets, Wear OS, Android Automotive OS, and Android TV. An Android Virtual Device sets the Android version and hardware characteristics, and has private storage for user data, SD card data, and cache. The emulator can simulate calls, text messages, locations, network speeds, rotation, hardware sensors, and Google Play Store access. It supports multiple instances, keyboard mapping, gamepads, and root access. The first launch may take about a minute; later launches can use a snapshot and start faster. Supported systems include 64-bit Windows 10 or newer, macOS 12 or newer, Linux, and ChromeOS. The recommended baseline is 16 GB RAM and 16 GB disk space, with higher requirements possible for newer API levels or larger virtual devices. Android Studio on ChromeOS deploys apps only to connected hardware devices.
