I was just wondering if it would be possible to make a fully featured Twitter Application with Titanium? An app like Twitter for iPhone or Osfoora..
yep, you sure can.
there actually is someone who has made one already, i'll have to look and get the link to his app.
i believe it's called "nigel", you can view a video of it here:
If anyone is wanting to make a full Twitter app, be sure to check out BirdHouse.
Cross-Platform Support & Up-to-Date: BirdHouse has been tested on Android with Linux and Mac as well as on iPhone, both using the latest Titanium Mobile SDK (1.6.2). It has been tested by others and is being maintained to fix any issues.
About: The script can send tweets, retrieve tweets, authenticate, "deauthenticate", and send custom API calls to Twitter. For sending tweets, a custom UI popup appears. It is designed to work similar to Titanium's Facebook module.
David Riccitelli's oauth-adapter doesn't work on Android, but some have forked it to work, such as Ketan Majmudar (go here for his code), I have tried other OAuth scripts as well, but I have been more successful with BirdHouse.
