I’ll introduce how to test Deep Link and Custom URL Scheme for Android and iOS apps in a development environment.

Background Knowledge

• Defining a Custom URL Scheme for Your App | Apple Developer Documentation

How to Test Deep Link and Custom URL Scheme

      example://action?id=yoW4Sei3
    
  

Python: Start SimpleHTTPServer Web Server

cd ~/Documents/url_scheme/
python -m SimpleHTTPServer 8000

Start ngrok

Start ngrok specifying Port 8000 as follows:

That’s all from the Gemba, where we want to test Deep Link and Custom URL Scheme for Android and iOS apps in the development environment.
