unable to Initialize AccountKit android studio. Initialization Error 501

Question

I wanted to create a simple app using AccountKit which shows "hello world" message upon successful login. "activity_main.xml" contains a simple "hello world" message. There were no errors in syntax but when i try to run this on my phone i am getting this error regarding account kit sdk initialization. I have clearly initialized the accountkit sdk in LoginActivity as given here . There is no function called initializeSdk() associated with AccountKit class. Please Help Me.

Answer 1

Create a new Class named as DemoApplication or any your prefer name that extends Application. Register this class in your Manifest file as shown in code below. then initialize the Fb Account kit in onCreate() on DemoApplication.java file

public class DemoApplication extends Application {

  @Override
  public void onCreate() {
       super.onCreate();
       AccountKit.initialize(getApplicationContext());
  } 
}

and there register this class in your Mainifest's Application element
