Answer 1

you have to initialize facebook SDK before setContentView, so add following line right above the setContentView

FacebookSdk.sdkInitialize(getApplicationContext());

Answer 2

One solution is to add the path of the Facebook SDK to "project.properties" in your project.

Like:

android.library.reference.1=../libfacebook/facebook-android-sdk-3.0.1/facebook

Answer 3

Just initialize FacebookSdk.sdkInitialize(getApplicationContext()); in your Application class. Because Application class initializes even before your activities gets initialized.

do just like this :

public class ApplicationController extends Application{

@Override
public void onCreate() {
    super.onCreate();
    FacebookSdk.sdkInitialize(getApplicationContext());
}

}

Answer 4

I was getting this error because I set the content view BEFORE sdkInitialize. The getting started guide has a comment referring to this.

https://developers.facebook.com/docs/android/getting-started#androidstudio

@Override
 public void onCreate(Bundle savedInstanceState) {
     super.onCreate(savedInstanceState);
     FacebookSdk.sdkInitialize(getApplicationContext());
     // Initialize the SDK before executing any other operations,
     // especially, if you're using Facebook UI elements.
}

So my code now looks like this:

@Override
 public void onCreate(Bundle savedInstanceState) {
     super.onCreate(savedInstanceState);
     FacebookSdk.sdkInitialize(getApplicationContext());
     setContentView(R.layout.activity_main);
}

Answer 5

I had also same error and just by relacing android-support-v4.jar with android-support-v13.jar solved the problem.

Answer 6

If you add facebook library to your application at Properties->Android , you should delete facebook.jar in your facebooksdk path/bin/facebook.jar. It cause error when link in eclipse. Then you clean your facebook sdk and your application. I hope will work fine.
