Integracja Facebook w aplikacji Android

Question

Czy istnieje api na Facebook do integracji z Androidem?

Mam wymóg publikowania zdjęć na Facebooku za pomocą aplikacji na Androida.

Proszę podać linki lub sugestie dotyczące tego ..

Answer 1

Jeśli miały czas do Google „Android SDK Facebooku” wy mieliście już natychmiast znaleźć oficjalny Android Facebook SDK: http://github.com/facebook/facebook-android-sdk

po użyciu go w projekcie mogę powiedzieć, że jest trochę szorstko wokół krawędzi, ponieważ nowe elementy oparte na API oAuth/Graph są dość młode, ale działa to dobrze z niewielkim szczypaniem.
