same proxy setup fails on Fiddler but works with MitmProxy

[Zhen]

I want to setup proxy for a c++ application for android.

Here is my setup:

adb reverse tcp:8888 tcp:8866

adb shell settings put global http_proxy localhost:8888

And then in my own app, point my c++ libccurl to use localhost:8888 as proxy and give it the fiddler pem.

Now, my problem is that this setup doesn't work on fiddler.

However, the same exact setup works with Mitmproxy. where it points to 8080 on host and using the pem from mitmproxy.

Does anyone have any idea why this might be the case?


Thanks

Hello Zhen,

Is there a specific reason you are using ADB reverse to explicitly map a port and to set the proxy? Usually, you should be able to set an Android proxy through the Android proxy settings (on the testing device or emulator) as explained here:
