I needed to add tapjoy to an android app so i wrapped thier sdk up for titanium; figured others could use it as well.
Tapjoy Advertiser SDK - Android - v9.0.1 for Appcelerator Titanium
var TiTapjoy = require('ti.tapjoy');
var status = TiTapjoy.requestTapjoyConnect('YOUR-APP-ID','YOUR-SECRET-KEY');
link to module to drop into your projects
https://github.com/n3wc/titapjoy/tree/master/dist/modules/android
iOS module coming soon(ish).
