How to listen to httpUrlConnection in Android app from Fiddler

omercs edited this page Oct 3, 2014 · 1 revision
  1. Setup fiddler at your PC to listen to remote connections
  2. Get your ip for proxy from fiddler. See fiddler instructions for that.
  3. Configure your device or emulator for proxy setup for this ip and port
  4. Visit your proxy at the browser like: http://yourIpAdress:8888
  5. Click to install fiddler cert
  6. Verify that you can see this cert at Settings->Security->Trusted Credentials->click User tab
  7. Try to visit some pages at the browser(at your device or emulator). You should see them at Fiddler now.
  8. When you run apps, they may use HttpsUrlconnection. It will not show up at the Fiddler. You need to do one more trick in Fiddler:
    1. In Fiddler click "Rules->Customize Rules"
    2. In opened script and find function OnBeforeResponse In the function body add following code: if (oSession.oRequest["User-Agent"].indexOf("Dalvik") > -1 && oSession.HTTPMethodIs("CONNECT")) {
      oSession.oResponse.headers["Connection"] = "Keep-Alive";
      }
