集成Facebook Android SDK 4.4.0后，应用程序在FacebookSdk.SdkInitialize（）上崩溃了吗？

Question

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);

Answer 1

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); }
