Android, Webkit and oAuth

Postby digitalspaghetti » Sat Jan 10, 2009 4:14 pm

Hi there,

I'm writing an android app for Brightkite and I would like to use their oAuth service to authorise the application.

I've successfully got the application to load up a webview to the site, however when I try log in, it instead invokes the browser on login and takes me to the mobile site.

Within my view, I have set the UA as a desktop browser, so if I can keep it within this it may work. Below are my two classes for the app, and any help would be appreciated.
