feat(Jakdojade) Add Disable ads patches

[TymekV]

Jakdojade is a popular Polish mobile app and website for planning public transportation routes in cities across Poland. This PR introduces patches to improve the user experience of the app.

• Package: com.citynav.jakdojade.pl.android
• Version Tested: 7.2.1

Ad removal strategy

This patch spoofs Jakdojade Premium in order to disable ads. Please note that Jakdojade Premium does not provide
any other client-side functionality beyond ad removal so spoofing it is the easiest way.

GMS Core

GMS Core is needed, beacuse Jakdojade uses Google Maps embeds, which break when the app is signed with a different keystore.

Status

• Disable Ads patch implemented and tested
• GMS Core support patch in progress

So it seems like maps works differnently, its not just gmscore support patch.. I think the maps sdk checks the cert inside the app, so if you find the relevant code and spoof the cert fingerprint (=signature) then it should work (without gmscore maybe?)

[TymekV]

I've fixed the issues. I'll research now how to deal with the maps problem.

[oSumAtrIX]

Got anywhere? Last i heard was that its merely necessary to spoof the signature thats passed to the maps sdk inside the app. If not, gmscore support patch would be needed.

I was trying to spoof the signature with no success. I'll check again if I'm mot missing any methods using Frida.
