In this Android tutorial, we’ll learn about the Android Virtual Device. It can also be written as AVD. We will go through what exactly an Android Virtual Device is and why and who uses it. Once we’re done with this, we’ll then see how we can set up an AVD. Without any further delay let us get started.
What is an Android Virtual Device?
The first question that comes in one’s mind would be, what is android virtual device? So, let us understand this. An Android Virtual Device is basically a device configuration. It is similar to Android Mobiles, Tablets, or any other Android device. The developers can test the applications that they have developed on AVDs. To understand in a simpler way an AVD is a software that imitates a real hardware android device. It has a hardware image, a storage system, applications, and other things just like a real device.
Why Android Virtual Device?
We need it during the development of an Android Project or Application. Since it provides a virtual representation of an application, it helps us to run our application on itself. It is required to ensure that our app works correctly. This is preferable over a real device because it eliminates the task of connecting a mobile device and installing the application again and again. It helps us test the app and its functions correctly and resolve malfunctions if any, immediately without much of a delay.
Who uses an Android Virtual Device?
Android Virtual Device is used mostly by the developers while they develop a new android application. They also use AVDs if they want to make changes in their existing application and check them effectively and immediately. So yes, basically Android Virtual Machine is mostly used by the Developers. To use AVDs, you can use emulators and configure it or create a new AVD. We will see in this article how you can create or use an AVD.

Characteristics of Android Virtual Device
Android Virtual Devices have the characteristics the same as our normal smart devices. Let us see some characteristics of Android Virtual Devices as follows:
