capture just browser or non-browser traffic

In fiddler for windows I can select if I capture just browser traffic, other traffic, or both. It would be great to have this in fiddler everwhere as well. (does it even capture non-browser traffic yet? If not obviously that would be needed first).

Hello Bjørn Hansen,

Fiddler works as an HTTPS proxy and will capture any traffic directed through that proxy, encrypted through the Fiddler root certificate. While this is valid for mobile browser traffic, it is not the case with Android applications. The thing is that Android applications (except the mobile browsers) are configured not to trust any user-installed CAs (certificate authorities), which means that, by default, most Android applications won't trust the Fiddler CA.

You can change the security configuration of an Android application through its codebase (if you have access to it). That means you will be able to capture its traffic in development mode only, as you will need to rebuild the application for the change to take effect.

Learn more on how to capture Android application traffic with Fiddler Everywhere in the following documentation section: https://docs.telerik.com/fiddler-everywhere/traffic/configure-android#inspecting-android-application-traffic

I have experienced capturing Android App traffic using Fiddler, some of HTTP traffic not found.

But using Wireshark the no-show hostnames appeared back to the HTTP row.

I think Fiddler wouldn't mainly support capturing traffic via browser, the non-browser functions might not support, is that right?

That's would be very good addition indeed.

To answer your question - yes, Fiddler will capture all HTTP/S traffic (that include all non-browser traffic) that is sent to it.
