Change the localization string in Facebook when you make the API calls:
Internationalization Facebook Connect
features are available many locales.
You can replace the en_US locale
specifed above with one of the
supported Facebook Locales. For
example, to load up the library and
trigger dialogs, popups and plugins to
be in Hindi (hi_IN), you can load the
library from this URL:
http://connect.facebook.net/hi_IN/all.js
So in the Android SDK change any calls to facebook to have the en_US Internationalization tag
If you want to match it to the phone's language then you will need to change the SDK to make a call to the Android system settings and replace the tag appropriately - http://developer.android.com/guide/topics/resources/localization.htmlt
