Key Developer Features
Sign in with Google+
Allow users to easily and securely sign in to your app using their Google+ credentials. This allows you to know who they are on Google+ and to build a more personalized experience in your app. Add sign in.
Share to Google+
Display a Share dialog that lets your users share rich content from your app, including text, photos, URL attachments, and location, into the Google+ stream. Add sharing with Google+.
Recommend content
Add a native +1 button so users can recommend content from your app. When users +1, they can also share content with their circles. These endorsements can give your app more credibility and help it grow faster. Add the +1 button.
