Hi,
I've been trying to test whether Admob banner ads are working via testing my app on an android device. No ads are displaying so it looks as though they aren't loading. So far I've tried exporting unsigned release APK, which gives me the error message "App not installed" when I try to load and open it on my phone, and debug APK, which works but doesn't display ads.
This is the code I've been using:
I'm new to this so there could be any number of things I'm doing wrong. Any advice would be really appreciated.
