Android Emulator

Android Emulator


Android Emulator is a virtual device used by the programmers to see the behavior and appearance of the APP. An emulator mimics the behavior of any actual Android device. The emulator is a prototype of an actual device and has almost all the functionalities of an actual device. The emulator can also have extended controls to record your App’s behavior.


An emulator is known as AVD or Android Virtual Device; however, there are several other emulators available (Free or Paid) also. These emulators may provide additional facilities. Genymotion and Blue stacks are examples of such emulators.

You can make calls; send SMS, use the internet and several other things with this emulator.
Android AVD is included by Android SDK. Android emulator can be configured with any form factor like a mobile device, Auto, Wearable device or Smart TV.

We can also deploy and test our app directly on the actual physical devices and most of the time it is the faster way to compile and test your app but you can’t keep each and every type of physical Android device with yourself, So emulator is a good option in such case. In some cases, the Android emulator runs faster than actual physical device deployment because of loading data faster.

As emulators are virtual machines basically so they need to consume your machine resources like RAM and processor, hence your machine tends to be slow. There is also instruction set conversion in between somewhere (Mobile devices generally have ARM instruction set). For this purpose, you can use accelerators. HAXM is an accelerator for Intel devices and it can boost the performance of your intel device considerably.
