My application can send http calls to and get data from my backend server just fine when tested with ionic serve. But when I build and run it on an android device it instead gives the error
EXCEPTION: Response with status: 0 for URL: null
I don’t think this is a CORS error, as my backend is set up to allow for that, and because other posts seem to imply CORS issues are not supposed to happen on device, only in serve. Any idea why this might be happening just on device and not in serve, and how i might fix it?
