        MenuItem menuItem = menu.findItem(R.id.share);
          // Get the provider and hold onto it to set/change the share intent.
        ShareActionProvider shareActionProvider = (ShareActionProvider) menuItem.getActionProvider();

        shareActionProvider.setShareIntent(getDefaultShareIntent());
        return super.onCreateOptionsMenu(menu);
    }

Answer 1

Dovresti usare il ShareActionProvider da ABS, non il titolo.

android:actionProviderClass="com.actionbarsherlock.widget.ShareActionProvider"
