public class FooActivity extends Activity implements Connectable, Disconnectable, Bindable {

    private Merlin merlin;
    private Button button;

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

        initMerlin();
        button = (Button) findViewById(R.id.button);
    }

    private void initMerlin() {
        merlin = new Merlin.Builder().withConnectableCallbacks().withDisconnectableCallbacks().withBindableCallbacks().build(this);
        merlin.registerConnectable(this);
        merlin.registerDisconnectable(this);
        merlin.registerBindable(this);
    }

    @Override
