Social Cafe Android Sample App

Sample app for social cafe, counterpart to the web version: http://social-cafe.herokuapp.com/

Author: Vikas Gupta (www.facebook.com/vg)

Installing

1. If you can't wait to try out the Social Cafe, the SocialCafe.apk is included in the root folder. Install it on your handset or emulator. Note that Single Sign On requires the Facebook app which can either be installed from the Google Play store (latest version) or using the Facebook.apk (old version) provided in the Facebook SDK.

2. Building and installing the samples requires you to add the Facebook SDK. Follow instructions at https://developers.facebook.com/docs/mobile/android/build/

3. Open Eclipse and create 'Android Project from Existing Code'. Use fbsamples/android-social-cafe folder as the Rood Directory

4. Link the Facebook SDK as Library in the Android settings of the Project Properties. Remove the existing Facebook Library if any as it likely be failing depending on your Facebook SDK location.

5. Note that the Single Sign On would not work using the pre-defined APP_ID in the SocialCafeApplication.java. This is because SSO requires defining the keyhash for your debug keystore in the app settings. You can however, create or use an existing app and define the og actions and objects as described below. If you are not familiar with the Open Graph concepts or would like a refresher, please read https://developers.facebook.com/docs/opengraph/

   1. Use the existing app or create a new Facebook app id at https://developers.facebook.com/apps and define following objects and actions:

      action - 'order', object - 'beverage'. Keep the default settings.

      action - like (built-in).

   2. Host some sample beverage objects (aka URLs) at the domain connected with your app. Instructions here - https://developers.facebook.com/docs/opengraph/objects/. If you don't have a host server readily available, you can use Heroku to setup a domain and host your URLs. Instructions here - https://developers.facebook.com/blog/post/558/

   3. Create a keyhash using your debug keystore and add this to your app settings. Follow instructions here - https://developers.facebook.com/docs/mobile/android/build/#sig

   4. Use your app id as the APP_ID in in SocialCafeApplication.java

   5. In SocialCafeApplication.java:onCreate() method, change the Drinks objects to the ones you defined.

6. Save, build and run the project.
