PhoneGap Android Plugin: ContactView error

I'm using PhoneGap + jQuery Mobile for a new mobile app.

This plugin is used to call native contact view of Android so you don't have to inject contacts in HTML.

https://github.com/phonegap/phonegap-plugins/tree/master/Android/ContactView

I've followed the instructions properly but it doesn't work for me, whenever I try to run (after all the initialization routine) this JS on Android:

    window.plugins.contactView.show(
        function(contact) {
            cons开发者_JAVA技巧ole.log(contact);
        },
        function(fail) {
            console.log(fail);
        }
    );

It shows this error:

Error: Status=2 Message=Class not found

Can anyone help?

Note: I haven't used any PhoneGap plugin before.
