Android emulator not connecting to localhost api

I have a Xamarin app and localhost API. I'm trying to connect to the API from the app, but it could not be found. I edited my applicationhost.config file and I tried localhost, 10.0.2.2 and my IP address in the call, but it was not working.

So, how do I configure simple API access? (The API itself is working well)

There is a simple workaround to connect Emulator & Simulator to localhost API's which I am using.

Download third party software NgRok for Windows at any specific location of your PC. It just contains one executable file called ngrok.exe. Now execute your service on your preferred browser. Than follow below steps.

Open your ngrok location on command prompt
Open your service URL(take from your browser) with prefix: ngrok http --host-header=rewrite
Now go to your browser where you have execute your service open another tab & type localhost:4040 than press enter -->Go to status there you will find your public URL which you can use in your mobile application.

Note: Url structure should be like this public const string BaseUri = "https://8c56892f.ngrok.io/"; followed by / in last. Try not to append unnecessary /, in command prompt.

Benifits

By using this method you can debug services from one Visual Studio to another.
Your URL will be active until you close command prompt.
In browser or command prompt track your requests status like Ok, not found etc.

That 10.0.2.2 address is used for the Google emulators. For the Microsoft emulator you want to use 169.254.80.80. If that doesn't work then it must mean you have the firewall on and it's blocking the traffic. That can be solved by adding a new incoming rule for the program or port.
