Problem deploying solution of android project on Visual Studio 2017


I have to work on an android application using visual studio. So I started by writing a simple "Hello World" application to print on the console.

It gives the following error.
1>------ Build started: Project: RestSharp.Android.Sample, Configuration: Debug Any CPU ------

========== Deploy: 0 succeeded, 1 failed, 0 skipped ==========

After looking for "Cannot find AVD system path. Please define ANDROID_SDK_ROOT" on Google, I thought I may have to set up an environment variable. So I added thid to the Path list in System Environmental Variable "C:\Users\soume\.android\avd". However, the error has not changed.

Please suggest what is wrong and how to fix this issue.

Thanks in advance.

Have you created new virtual device before you run the app?

1- Start your Android Studio.

2- Create a New Project to be able to create or delete virtual devices.

3- Delete any virtual devices if found.

4- and create virtual device via AVD manager

AVD ManagerI am using Visual Studio Community Edition 2017 on Windows 10 Home Edition. I have opened the Android Virtual Device Manager and see 4 devices listed here. Do I delete all four of them?
