Return back to the parent activity from subactivity

Question

My application supports twitter and needs to open browser for OAuth. When the user clicks the Share on Twitter button, the main activity will create another subactivity (TwitterActivity) to handle twitter authentication issues.

Here is a flow graph showing how activities are invoked currently. Main is short for MainActivity and Twit for TwitterActivity.

     startActivity()       OAuth intent           OAuth callback       finish()
Main ---------------> Twit ------------> Browser  --------------> Twit --------> Browser

As you may notice, after the TwitterActivity calls finish() to stop, it will now return back to MainActivity, but Browser instead. How can I make it return back to MainActivity? Many thanks

Answer 1

try setting the noHistory attribute for the Browser's activity to true in the Manifest.

Answer 2

You could consider switching to browserless xAuth authentication method. It provides much more user friendly experience http://apiwiki.twitter.com/Twitter-REST-API-Method:-oauth-access_token-for-xAuth.
