Make sure you have latest preview installed on your PC.

Before running the code, do nuget package addition in visual studio. Create a nuget.config file to the root of your project and add the following feed(s) with these commands:

7. Battery Charge Indicator Sample Application for Android

Hi
I have created a MAUI project in VS 2022 preview, which is working fine initially with emulator, but now Emulator is not showing. When I create Xamarin project Emulator is showing and application is running on that Emulator.

Please help me to resolve this issue as it occurs developing application

What I have tried:

1. I had delete/renamed
   Copy Code
   C:\Users\username\AppData\Local\Xamarin
   C:\Users\username\AppData\Local\Microsoft\VisualStudio\17.0_e17a11fb\ComponentModelCache

2. I had repair VS 2022 preview

3. I had reinstall MAUI

Sorry for the late replay.

I have created the above using VS 2019 Preview. I'm not sure whether VS 2022 Preview is stable for xamarin devs. I need to check on this and will revert u.
