Facebook SDK causing errors in my android project

Question

I'm trying to implement a Facebook login button to my Android application. I imported the SDK to my IDE (eclipse) but when I add the Facebook reference to my project errors show. I'm using navigator drawer and volley lib in my project and that's where I have errors .

what I have to do to fix this error?

Answer 1

This is actually easy to fix.

1. Right click on the Facebook-SDK project in eclipse
2. Go to Java build path
3. Under "Order and Export" Deselect (ie Uncheck) Android Private Libraries
4. Simultaneously clean and build both your project and the Facebook-SDK project
