fixed the issue. Will look into that further If the function you want to call is already in the Activity then you can do something like the code below and it will work -
The key is, in the Fragment you have a method called getActivity() which you can use to access methods in your activity.
code :
public interface ExternalInterface {
  public void gotoNext();

public MyActivity implments ExternalInterface {
 public void gotoNext(){
 //Do something here
 public MyFragment extends Fragment{

public void onCreateView(....){
 ((ExternalInterface )getActivity()).gotoNext();

this one helps. Instead of using "Add Web Reference" within Visual Studio, I used "Add Service Reference".
On the server side, I upgraded to .NET 3.5

With these it helps You need to implement it in your class not having an instance of it.
code :
public class MainActivity extends FragmentActivity implements InterfaceUpdateUISummary
new SelectDataSummary_Async(this).execute();
 updateUI = (InterfaceUpdateUISummary) activity;

it fixes the issue I'm working on a project where I have added an external reference. I have searched through this reference with the object explorer. I have found an interface with a function I would like to use. Now to implement an interface you will need a class which have all the functions of the interface. , You can do this with reflection:
code :
interface MyInterface { }

public static void Main()
    Assembly asm = Assembly.Load("externalAssembly");

    var interfaces = asm.GetTypes().Where(t => t.IsSubclassOf(typeof(MyInterface)));

    foreach (var i in interfaces)
        Console.WriteLine(String.Format("Found: {0}", i.Name));
Reference Fragment/AppCompatActivity from FragmentActivity

help you fix your problem You shouldn't try to get a reference to an Activity, this can cause memory leaks and can make code more fragile.
You should look into communication ways between Activities such as using a BroadcastReceiver or an EventBus.
code :
public class MainActivity extends AppCompatActivity{

    public void onMessageEvent(MessageEvent event) {
        // Show the message.
public class F2 extends FragmentActivity{

    // Sending "Hello from F2" to anyone listening.
    public void sendMessage() {
        MessageEvent event = new MessageEvent("Hello from F2");

Any of those help Don't worry about one tiny little vtable lookup, unless profiling indicates that it's a bottleneck. (Hint: it probably won't be.) How should the compiler know what the concrete return type of ConcreteFoo() is going to be? If Foo::Bar() is virtual, the compiler cannot create a static call to Foo.Bar() because Foo's type is unknown at compile time.
If you know the actual type of Foo, say Biz, you can do away with the reference:
