What is an Android studio emulator?

edit

An Android Studio emulator is a feature in the Android Studio development tool that allows developers to test their applications on a virtual Android device without needing a physical device. The emulator creates a virtual environment that mimics the hardware and software specifications of an Android device, enabling developers to run and test their applications on multiple configurations and versions of Android. It provides a convenient way to test the app's functionality, performance, and user interface without needing to purchase or borrow a physical device.
