I tracked the culprit down to the [email protected] cordova platform. It now requires the new cordova-plugin-whitelist plugin.
It can be installed with
cordova plugin add cordova-plugin-whitelist
or by adding
<plugin name="cordova-plugin-whitelist" spec="1" />
to config.xml, and then it is configured with
<allow-navigation href="https://stackoverflow.com/questions/30060534/*" />
in place of the old, <access origin="https://stackoverflow.com/questions/30060534/*" />
tag.
It’s a little annoying that the log doesn’t spit out the “whitelist rejection” error messages anymore when a problem like this comes up (that would have saved me a ton a time), but maybe that’ll come later.
