WebViewExample.java

public class Insta extends Fragment {
	WebView webView;

	@Override
	public View onCreateView(LayoutInflater inflater, ViewGroup container,
			Bundle savedInstanceState) {
		View root = inflater.inflate(R.layout.activity_my_insta, container,
				false);
		webView=(WebView)root.findViewById(R.id.webView);
		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
		public void onPageFinished(WebView view, String url) {

			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);
