I'm trying to integrate Facebook SDK in my android app. I downloaded facebook-android-sdk-4.5.1 and followed the steps in the developer guide. As I'm trying to run the sample HelloFacebookSample placed in the samples folder of the SDK, I'm getting the following error:

I'm trying Android 2.2. Is this an issue? Or anything I missed? Can someone guide me please.

  • Have you tried on different devices (OS versions)? maybe using genymotion? if this is always reproducible then you might have an issue with your IDE and/or environment – ifaour Sep 09 '15 at 13:06

The Facebook SDK requires a minimum Android API version 15 (Android 4.0.3, or ICE CREAM SANDWICH).

  • What is wrong with my answer? It's factual and even backed up by a reference which confirms this fact. – IanS Jun 20 '16 at 13:21
  • Nothing is wrong with your answer. Probably someone was just lazy enough to read carefully the question and see that OP uses Android 2.2 (API level 8), while FB SDK **requires** API 15 as it was pointed by you. – Volo Sep 21 '16 at 10:25

Yes, since FB 4.5.1 SDK required API 9 to run (that is Android 2.3). You can check it here: https://web.archive.org/web/20150821025823/https://developers.facebook.com/docs/android

Requires Android API 9.

It can't be run on previous Android versions since it uses new API methods/fields (in your case exception is caused by accessing the Locale.ROOT constant which was added only in API 9).

Starting from version 4.6.0 FB SDK started to require API 15: https://developers.facebook.com/docs/android/upgrading-4.x
