Cannot change orientation (always portrait)

Something happened in my app that I cannot change orientation anymore.
I cannot trace when it became to happen, but last things I did were upgrading cordova and installing phonegap-googlemaps plugin.

I have followed cordova documentation and set this in my config.xml:
<preference name="Orientation" value="default" />
but nothing changed after cordova clean and ionic build android

Can somebody give me a clue ?
