android sdk instance could not be loaded. please check your internet connection

Android Emulator in Visual studio can not be loaded without internet connection. Any solution will be appreciated so i can use emulator in visual studio offline. enter image description here

I had the same problem, and I resolved changing the repository to Google Repository in Visual Studio SDK Manager.

For anyone having trouble with this and finding "Visual Studio SDK Manager" and to improve on the other answer (can't comment because I have no reputation):

Go to Tools > Android > Android SDK Manager and on the right bottom corner there's a gear, click on Repository and change it to Google.
