In brief, an Android emulator is a mobile emulator that gives us the perception of an Android device. The device can be any of those released to the market by the manufacturer such as Samsung Galaxy S22 or Google Pixel 7. As a tester, we run the emulator on a PC and install our application to test it. If it is a web application, then we explore it using a browser to check if an Android user will face any difficulty in operating the app or not.
