Tuenti is a social network (as facebook) but only used in Spain.
I've made a little app to acces to his web mobile version that allows me to search contacts, and direct access to some sections.
Tuenti doesn't have public API, so I must use a WebView to show the content.
You can find the simple code here: http://github.com/agonzalezro/tuenti
* Preferences view to setup your tuenti account.
* Ajax to show counters at messages and wall posts.
* If you are writting in a input of the page and use the sym key, the app open the filter.
