How to proper setup for xamarin development as c# developper?

Issue

I'm facing a serious issue and don't know how to fix it, i'm a c# developper but i'm new to mobile development using xamarin in visual studio, i've dowloaded the xamarin with all the installation package, then i went throught all the step to creating a xamarin form, i've downloaded all the android sdk down to Nougat version (7) But when to trying to run the app, it shows errors. I looked all over the internet but i got no correct answer. So if someone know a solution to this problem, please help me with this.

Solution

You could check the path of the directory. And test with removing the none english character to rebuild and debug the application on the device.
