I'm trying to load images from my backend into my android emulator.
I already implemented this solution: Xamarin Android issue connecting via HTTPS to site with self-signed certificate: "Trust anchor for certification path not found.". API JSON calls are working fine, just the images are not loading.
Accessing images in the emulator chrome browser is working.
My question is if anyone knows how to make loading images from local backend work?
Example code:
