Facebook integration in Android app

Question

Is there any api for facebook to integrate into android?

I had a requirement to post images to facebook via the Android app.

Please provide links or suggestions regarding this.

Answer 1

If you spent time on Google's “Android Facebook SDK”, you would immediately find the official Android Android SDK: http://github.com/facebook/facebook-android-sdk

Using it in the project, I can say that it is a little rough around the edges, since the new material based on the oAuth / Graph API is quite young, but it works well with a little tweaking.
