New Facebook API 3.0. and ActionBarSherlock compatibility

Question

I\'m reading facebook Android API 3.0 documents, and I do not understand what does session has to do with background activities. In all examples I\'m supposed to extend \"Facebo

Answer 1

You do not need to inherit from anything, if you don't provide an app_id through code, you must specify it in your application metadata (and in your strings.xml). See https://developers.facebook.com/docs/reference/android/3.0/Session#APPLICATION_ID_PROPERTY

In your AndroidManifest.xml, you need to add:

<application android:label="@string/app_name" ...>
  ... other activity stuff here ...
  <meta-data android:name="com.facebook.sdk.ApplicationId" android:value="@string/app_id"/>
</application>

And then add app_id as a string in your string.xml.

Answer 2

FacebookFragment is not public and is not intended for use by applications.

The samples do mostly use FacebookActivity though, and yes--you do not need to extend FacebookActivity. As you mention, SessionLoginSample demonstrates this, and if you are not using FacebookActivity you should handle Session serialization and override/forward onActivityResult as illustrated there.

That said, it sounds like the main issue you are hitting is around setting the applicationId. You can set applicationId in code or in meta-data.

In code:

To set it in code, define a String constant MY_APP_ID that contains your app id and replace the line:

session = new Session(this);

with:

session = new Session.Builder(this).setApplicationId(MY_APP_ID).build();

In metadata:

To set it in meta-data, add the following to your AndroidManifest.xml inside the application tag but outside of any activity tags:

<meta-data android:name="com.facebook.sdk.ApplicationId" android:value="@string/app_id"/>

Then, in values/strings.xml, add a value for app_id that has your app id:

<string name="app_id">1234567890</string>
