I reproduced the very same error by importing the latest version of the Wikitude plugin in an AppBuilder project and building it for Android. Googling a bit, I found this issue
in the Wikitude plugin's repo. It seems like the latest version is only compatible with Cordova 4.0, which is coming in AppBuilder later this month. However, as a temporary workaround, you can download Wikitude v4.1.0-3.0.1
, which is compatible with Cordova 3.7.
I hope this helps.
