		WebSettings webSettings=webView.getSettings();
		webSettings.setJavaScriptEnabled(true);
		webView.loadUrl("https://instagram.com");
		webView.setWebViewClient(new MyWebViewClient());

		

		getActivity().setTitle("Instagram");
		return root;
	}
	private class MyWebViewClient extends WebViewClient {

		@Override
		public boolean shouldOverrideUrlLoading(WebView view, String url) {
			view.loadUrl(url);
			return true;
		}

		@Override

			super.onPageFinished(view, url);
		}
	}

}

You can initialize it in onCreate in Acivity and onCreateView in fragment

Below is code snippet

public class DcsAdmissonPortalFragment extends BaseFragment {
LinearLayout progressbar;

public DcsAdmissonPortalFragment() {
    // Required empty public constructor
}

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

}

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {
    View rootView = inflater.inflate(R.layout.fragment_dcsadmissionportal, container, false);
    progressbar=(LinearLayout) rootView.findViewById(R.id.progressbar_layout);
    progressbar.setVisibility(View.VISIBLE);
    WebView myWebView = (WebView) rootView.findViewById(R.id.webview);
    myWebView.loadUrl("http://csadmissions.gcu.edu.pk/");
    WebSettings webSettings = myWebView.getSettings();
    webSettings.setJavaScriptEnabled(true);
    myWebView.setWebViewClient(new MyWebViewClient());



    // Inflate the layout for this fragment
    return rootView;
}

@Override
public void onAttach(Activity activity) {
    super.onAttach(activity);
}

@Override
public void onDetach() {
    super.onDetach();
}

private class MyWebViewClient extends WebViewClient {

    @Override
    public boolean shouldOverrideUrlLoading(WebView view, String url) {
        view.loadUrl(url);
        return true;
    }

    @Override
    public void onPageFinished(WebView view, String url) {
        progressbar.setVisibility(View.GONE);
        super.onPageFinished(view, url);
    }
}

}

OnAttach method functionality in this code ?? in fragment i used this method to cast my interface variable into the calling activity variable..
just like
public void onAttach(Activity activity) {
myInterfaceVariable = (InterFace) activity;

}

then we can send values to activity from fragments by this
myInterfaceVariable.methodName(myValues);
