Android - will users trust embedded webview for twitter authorization?

Will users trust if I use an embedded webview to authorize my app with twitter? I could obviously be providing a fake page to catch their login. Or do they expect me to launch a browser so they can see the url etc? If I do that, is there any way to automatically return to my app when finished? How do other apps handle this? Expecting the user to press the back button after they're done开发者_运维技巧 isn't very graceful, as the oauth process involves about 3 page redirects in my case.

Users seem to trust an embedded webview, especially if you place it in a "pop-up" dialog. We have done that in some of our apps (http://larvalabs.com). Once authorized, it is possible to get a callback to automatically return to your app, sparing the user the hassle. See for example this approach:
