I have integrated the latest Facebook Android SDK 4.4.0 in my Xamarin Android app but it is crashing at this line: 

FacebookSdk.SdkInitialize (this.ApplicationContext);

Could you please let me know if this is a bug in the latest Facebook Android SDK 4.4.0?

I have even tried running the Sample given in the Facebook Android SDK 4.4.0 but it too is crashing at the same line: FacebookSdk.SdkInitialize (this.ApplicationContext);

FacebookSdk.SdkInitialize (this.ApplicationContext);

Initialize FacebookSdk in onCreate before inflecting layout.like,

@Override
 protected void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);

       //Initialize FacebookSdk here
       FacebookSdk.SdkInitialize (this.ApplicationContext);  
  
       setContentView(R.layout.activity_main);
}

  • I already called the FacebookSdk.SdkInitialize (this.ApplicationContext); before setContentView() but its still crashing. – Ingrid Cooper Jul 31 '15 at 11:21
