I have a Google Plus page
Google Plus
https://plus.google.com/u/0/b/101839105638971401281/101839105638971401281/posts
and an Android application.
If the user has the Google+ app installed, you can do this:
startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse("https://plus.google.com/101839105638971401281/posts")));
Notice the syntax of the URI, and that it doesn't contain /b/id/.
/b/id/
