Intercept traffic from android app

Question

I need to intercept requests from the mobile application to take advantage of its internal api. In the application there is a chat, I need to receive the information that the server periodically sends to the application. For this, I installed Genymotion with the Xposed + module to bypass SSLPinning and Fiddler as a proxy (tried also Charles). After that I see some of the traffic from the application (long-polling requests), but the events I need are not displayed, although the application still receives them and displays them.

Can I somehow intercept absolutely all traffic from the application and what should I do to do this? Thank you in advance)

Answer 1

1. On Fiddler side you have to enable in the settings Allow remote computers to connect .

2. You also need the IP address of your computer in your home network, eg 192.168.0.13

Now start the virtual device and configure the proxy (taken from Genymotion FAQ ):

How do I configure proxy settings in my virtual device? In your virtual device:

1. Click Menu > System settings.
2. In Wireless & Networks, select Wi-Fi.
3. Click WiredSSID and hold it down for two seconds.
4. Click Modify Network.
5. Check Show advanced options.
6. In Proxy settings, select Manual.
7. Enter the proxy settings ( the noted IP address of step 2 of your PC and port 8888 )
8. Click Save.
