Emulators | Role of emulators in Android Application Development

The Android Emulator simulates Android devices on your computer so that you can test your application on a variety of devices and Android API levels without needing to have each physical device.

The emulator provides almost all of the capabilities of a real Android device. You can simulate incoming phone calls and text messages, specify the location of the device, simulate different network speeds, simulate rotation and other hardware sensors, access the Google Play Store, and much more.

Testing your app on the emulator is in some ways faster and easier than doing so on a physical device. For example, you can transfer data faster to the emulator than to a device connected over USB.

The emulator comes with predefined configurations for various Android phones, tablets, Wear OS, and Android TV devices.
In short, An Android emulator is an Android Virtual Device (AVD) that represents a specific Android device. You can use an Android emulator as a target platform to run and test your Android applications on your PC. Using Android emulators is optional.

Launch the Android Emulator without first running an app

To start the emulator:
1. Open the AVD Manager.
2. Double-click an AVD or click Run

The Android Emulator loads.

While the emulator is running, you can run Android Studio projects and choose the
emulator as the target device. You can also drag one or more APKs onto the emulator to
install them, and then run them.
