Android - Post Bitmap to Facebook

Question

I'm using this solution: How to post Bitmap to facebook using facebook sdk? to post a bitmap to Facebook but how do I modify this code to allow the user to sign in to Facebook if they are not already signed in when pressing the 'Share Photo' button? I don't want to get the user to sign in when the app launches - I only want them to sign in to Facebook when they click the Share button.

Thanks in advance!

Just check if there is no logged in person call the facebook login; else continue sharing.
