I am following the below documentation in order to view the traffic from an Android device. However, my traffic is not being captured in Fiddler and when I have the manual proxy settings enabled then my device appears to block any traffic. Could you help please? Are there any other instructions that I can follow?

Thanks. 

I'm using Fiddler Classic and android Emulator - MEmu. I have installed some android application there.

Of course I have installed fiddler certificates on my host and on android also i moved them to the system folder, I set up fiddler proxy in the Wi-Fi settings and everything works fine, I can receive all https traffic but somehow in this application when I'm trying to log-in the application logs in but in the fiddler I don't have any activity, it is just empty at this moment. Same thing when I enter wrong password the application says me "Wrong password" which means it sends request to the server somehow but fiddler doesn't have any requests when I press the button "Log in".

How is this possible? Can application bypass proxy that set up in the wi-fi connection settings in the android somehow? Or how is it possible even it theory?

I also tried android firewall with block all connections option on, when I Log in in the application with this firewall that blocks everything - I have error in the application and in the blocked list I can see requests like IP address and some urls, so why I can't see this requests in the fiddler?

 

Hello
I am Using Fiddler and Nox Player.

How Do i Fix that?
I already tried 
To Reset and re install the cert but didnt work.
any other solutions?

 

I am trying to capture traffic using Fiddler from an Android app running on an emulator (I am using MuMu).  I got most of what I was trying to accomplish. I added the required cert to Android and I can see most http/https traffic fine.

 

The issue I am facing is that I cannot see requests from the app that go to http://127.0.0.1:26284. I understand that the localhost for the Android emulator is different than my machine which is running Fiddler. I did some searching and found info on Android networking (https://developer.android.com/studio/run/emulator-networking) and 10.0.0.2 but I am not sure how to use that info or if it is even relevant to my issue.

 

For what I do have working, I set the proxy in the emulator to my actual machine's address (the one running Fiddler) and set it to bypass the proxy for 127.0.0.1 (otherwise the app wouldn't work as the calls to localhost would fail).

 

My goal is to be able to see the request/responses on the emulators localhost. Is it possible via Fiddler?  Maybe adding some redirects or something like that, just so I can see the request/response? Or any other way at all? I do not have access to change the calls in the app that go to 127.0.0.1.

 

Please let me know if there is any additional info that I can give that may help. This is my first time working with emulators and proxies.
