+OpenSocial Android client library -- friendlist demo
+
+friendlist is a simple sample application designed to introduce the
OpenSocial
+client library for Android. It includes a single Activity which first
prompts
+the user to choose one from a list of OpenSocial providers, then uses
three-
+legged OAuth to authenticate the user and fetch all friends from the
selected
+provider. The list of friends is rendered directly in the Android
application
+using the included View. The user can tap a name to see all information
+available for that friend.
+
+This is an Android application, and you will need to download the Android
SDK
+in order to build and run it:
+
+1. If you haven't already, download the latest Android SDK from
+ http://developer.android.com/sdk/index.html and unzip it.
+2. Open build.properties and update the sdk-location property to point to
the
+ location of your downloaded SDK.
+3. OPTIONAL: If necessary, open default.properties and update the SDK
target
+ from the default level.
+4. To run the application in the Android emulator, first launch the
emulator
+ (see http://developer.android.com/guide/developing/tools/emulator.html
if
+ you're new to Android), then open a new command line window, navigate to
+ the friendlist directory, and execute 'ant install' -- you should see
+ "OpenSocial Friend List" in the set of applications. From here, you can
+ invoke 'ant reinstall' to reinstall the application or 'ant uninstall'
to
+ remove it from the application set.
+
+
+- File contents:
+
+. AndroidManifest.xml:
+ Standard AndroidManifest which declares FriendListActivity and
+ OpenSocialChooserActivity and requests INTERNET permission.
+
+. build.properties:
+ Properties file for ant.
+
+. build.xml:
+ Build file for ant.
+
+. default.properties:
+ Specifies Android target level.
+
+. src/org/opensocial/android/demos/friendlist/FriendListActivity.java:
+ Subclass of OpenSocialActivity; displays a list of OpenSocial providers
to
+ select from, then fetches the user's friends once the user is
authenticated
+ to the selected provider.
+
+. src/org/opensocial/android/demos/friendlist/FriendListView.java:
+ Subclass of View; displays the user's friends.
