Answer 1

It's looking for your ConnectPlugin class to be in the org.apache.cordova.facebook namespace. Check either what you have set for the package at the top of your ConnectPlugin.java file or under the org.apache.cordova.facebook namespace is there any file named ConnectPlugin.java.

The moto is that you have to kept a file under the org.apache.cordova.facebook namespace and name should be ConnectPlugin.java
