It was the type of encoding from where I get the code.
The named character reference ' (the apostrophe, U+0027) was introduced in XML 1.0 but does not appear in HTML. Authors should therefore use ' instead of ' to work as expected in HTML 4 user agents.
I’m already take it off to test, and now I’m working just with the config.xml, like the plugin documentation says to do.
My app would work on emulation and device with Xcode, and ionic view, but not with ionic emulation or device run. Then I added
<allow-navigation href="*"/>
to config.xml and it worked on all these platforms. Allowing navigation everywhere was not recommended (for security reasons I don’t understand), so I was looking for something more specific and noticed ionic temporarily changed the content tag to
which works and presumably doesn’t have security issues.
A bit of downside is that either content element above keeps Xcode from running the app. Generally I prefer ionic for device and emulation testing, since it’s easy to see $log and some system messages (which I don’t see in Xcode, though maybe I need to be informed about how to better use Xcode). The Xcode console, however, displays messages the ionic doesn’t, which can be invaluable on rare occasions. If I’m missing a way to see the Xcode console messages in an ionic run, someone please enlighten me.
