Android : Capturing HTTP Requests with non-rooted android device

Solution 1:

You could install Charles - an HTTP proxy / HTTP monitor / Reverse Proxy that enables a developer to view all of the HTTP and SSL / HTTPS traffic between their machine and the Internet - on your PC or MAC.

Config steps:

• Let your phone and PC or MAC in a same LAN
• Launch Charles which you installed (default proxy port is 8888)
• Setup your phone's wifi configuration: set the ip of delegate to your PC or MAC's ip, port of delegate to 8888
• Lauch your app in your phone. And monitor http requests on Charles.

Solution 2:

There is many ways to do that but one of them is fiddler

Android Configuration
