Android internet call pickup

Question

I want to create an application that intercepts an HttpPost call to a website, logs all the header information. There will be a Java application on the computer that uses adc logcat to identify the header information, make a call, and then send the result as data in the intent of the translation, to then use it on the device.

I understand how to do this using adb so that it only works with my applications (using alternatives to standard connection libraries), but I don’t know which classes / methods to rewrite / extend so that they appear as an Internet connection, allowing it to work with any application.

my intention is to end up with something similar to setting up internet pass on htc devices, working perfectly on raspberry pi.

perhaps by doing this, creating a “fake” Wi-Fi connection in the wifi manager and using it.
