Wikitude

Hello.

I'm starting a application using android studio and wikitude but I get the message "Error:(23, 15) error: cannot find symbol method getLicenseKey(String)" when I generate the ArchitectView life-cycle events.

This is my code :

package com.example.garuda_diicc.appprueba7;

        import android.support.v7.app.AppCompatActivity;
        import android.os.Bundle;

        import com.wikitude.architect.ArchitectView;
        import com.wikitude.architect.StartupConfiguration;
        import java.io.IOException;
        public class PuntoInteres extends AppCompatActivity {

            protected ArchitectView architect;

            @Override
            protected void onCreate(Bundle savedInstanceState) {
                super.onCreate(savedInstanceState);
                setContentView(R.layout.punto_interes);
                this.architect = (ArchitectView)this.findViewById(R.id.vistarq);
                final StartupConfiguration config = new StartupConfiguration("");
                config.getLicenseKey("xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx");
                this.architect.onCreate(config);

    }

    @Override
    protected void onResume() {
        super.onResume();
        if (this.architect != null){
            this.architect.onResume();
        }

    }

    @Override
    protected void onPause() {
        super.onPause();
        if (this.architect != null){
            this.architect.onPause();
        }
    }

    @Override
    protected void onStop(){
        super.onStop();
    }

    @Override
    protected void onDestroy(){
        super.onDestroy();
        if (this.architect != null){
            this.architect.onDestroy();
        }
    }

    @Override
    protected void onPostCreate(Bundle savedInstanceState){
        super.onPostCreate(savedInstanceState);
        if (this.architect != null){
            this.architect.onPostCreate();
        }

        try{
            this.architect.load("");
        }
        catch (IOException e1){
            e1.printStackTrace();
        }
        super.onPostCreate(savedInstanceState);

    }
}
