I'm trying to integrate the Facebook SDK with my Android project with Eclipse.But as we know the latest Facebook SDK is in .aar form and it is supposed to be used in Android Studio.But for some reason i have to continue working with Eclipse.
I tried to extract the .jar file and the res folder and drop them into my project directly,but then my project was full of errors,like classed couldn't be found and such.
So here is one error that appeared when i tried to add a LoginButton to my activity_main.xml
<com.facebook.login.widget.LoginButton
android:id="@+id/login_button"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal"
android:layout_marginTop="30dp"
android:layout_marginBottom="30dp" />
