How the Emulator Works
The Android Emulator simulates various Android devices on your computer so that you can test your application on a variety of devices and Android API levels without the need for actual physical devices.
How the Emulator Works
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 Google Play Store, and much more.
