I am working with android app for the web view. It loads the webpage but i cant make more actions on the page using my app. when I am choosing a hyperlink from the page it shows a popup"complete the action using chrome,opera etc.." how can I use this without such browsers..I nedd to browse web contents using my app. how it possible??
I used the code
webView = (WebView) findViewById(R.id.webView1);
webView.getSettings().setJavaScriptEnabled(true);
webView.loadUrl("http://www.google.com");
please help me since I am new to android and thank you.
wv.loadUrl(url);
wv.setWebViewClient(new MyWebViewClient());
Your WebViewCLient class would look like this:
class MyWebViewClient extends WebViewClient {
#Override
// show the web page in webview but not in web browser
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return true;
}
#Override
public void onPageFinished(WebView view, String url) {
super.onPageFinished(view, url);
webProg.setVisibility(View.GONE);
}
#Override
public void onPageStarted(WebView view, String url, Bitmap favicon) {
super.onPageStarted(view, url, favicon);
}
#Override
public void onLoadResource(WebView view, String url) {
super.onLoadResource(view, url);
}
}

Trying to load this website with WebView, but it just show a blank page.
I can open other website with no problem, but not the above website. Possible the web developer block it? The website is not owned by me.
guideView = (WebView) findViewById(R.id.guideView);
guideView.setWebViewClient(new myWebClient());
guideView.getSettings().setJavaScriptEnabled(true);
guideView.loadUrl("https://sapsnkra.moe.gov.my/ibubapa2/index.php");
}
public class myWebClient extends WebViewClient {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return false;
}
#Override
public void onPageStarted(WebView view, String url,
Bitmap favicon) {
super.onPageStarted(view, url, favicon);
}
#Override
public void onPageFinished(WebView view, String url) {
super.onPageFinished(view, url);
}
}
I tried to setWebChromeClient, but it do not work as well.
This link is apparently is blocked to access. I tried to access and dont work.
Make sure this .php is working to network access. As it is a .gov url there may be blocks.

oncreate
webView = (WebView) findViewById(R.id.webView1);
webView.setClickable(true);
webView.setFocusableInTouchMode(true);
webView.getSettings().setJavaScriptEnabled(true);
webView.setWebViewClient(new myWebClient());
if (Build.VERSION.SDK_INT < 8) {
...
} else {
webView.getSettings().setPluginState(WebSettings.PluginState.ON);
}
webView.loadUrl("www.example.com.");
WebViewClient
public class myWebClient extends WebViewClient {
#Override
public void onPageStarted(WebView view, String url, Bitmap favicon) {
super.onPageStarted(view, url, favicon);
}
public void onLoadResource (WebView view, String url) {
}
#Override
public void onReceivedError(WebView view, int errorCode, String description, String failingUrl) {
webView.loadUrl("file:///android_asset/myerrorpage.html");
}
public boolean shouldOverrideUrlLoading(WebView view, String url) {
// TODO Auto-generated method stub
progress.setVisibility(View.VISIBLE);
view.loadUrl(url);
return true;
}
#Override
public void onPageFinished(WebView view, String url) {
super.onPageFinished(view, url);
progress.setVisibility(View.GONE);
}
}
You must override your shouldOverrideUrlLoading() method in WebViewClient class and following code
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
if (Uri.parse(url).getHost().equals("www.example.com")) {
// This is my web site, so do not override; let my WebView load the page
return false;
}
// Otherwise, the link is not for a page on my site, so launch another Activity that handles URLs
Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(url));
startActivity(intent);
return true;
}
Go through the documentation for more information.
Use a if clause in your shouldOverrideUrlLoading method that returns false;
Example from Building web apps in web views
if (Uri.parse(url).getHost().equals("www.example.com")) {
// This is my web site, so do not override; let my WebView load the page
return false;
}
I am developing an app, in that I want to detect each time when a new url gets loaded in webview and then display that url in edittext.
I tried many solution and googled. But, not found significant solution which solves my purpose..
My Code is:
wv.getSettings().setJavaScriptEnabled(true);
wv.setWebViewClient(new WebViewClient()
{
public boolean shouldOverrideUrlLoading(WebView view, String url)
{
String url_new = wv.getUrl();
Log.v("","Webview URL: "+url_new);
edittext.setText("http://"+url_new);
return true;
}
});
Not even printing the Log Statement :(
Please Help..!!
Thanks in advance..!! :)
First off the code you're posting is returning true from shouldOverrideUrlLoading which means you've just prevented the webview from navigating to any location.
Second off, shouldOverrideUrlLoading will not get called for any urls you pass to the webview.loadUrl API. As suggested in one of the other answers, onPageStarted is the simplest API to use for this.
You can use the code below to play around with the APIs:
wv.setWebViewClient(new WebViewClient()
{
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url)
{
Log.v("","Webview shouldOverrideUrlLoading URL: " + url);
return false;
}
#Override
public void onPageStarted(WebView view, String url, Bitmap favicon){
Log.v("","Webview onPageStarted URL: " + url);
}
});
This is the code I use in my applications.
WebView view = (WebView) findViewById(R.id.myWebView);
EditText edit = (EditText) findViewById(R.id.myEditText);
view.setWebViewClient(new WebViewClient(){
public void onPageStarted (WebView view, String url, Bitmap favicon){
edit.setText(url);
}
});
Set WebViewClient to your webview and geturl on when page finshed laoding
class MyWebView extends WebViewClient {
#Override
public void onPageFinished(WebView view, String url) {
editText.setText(view.getUrl());
}
}
set this WebViewClient to your webview ..
webView.setWebViewClient(new MyWebView());
You can override onLoadResource() method of WebViewClient :
wv.setWebViewClient(new WebViewClient() {
public void onLoadResource(WebView view, String url) {
edittext.setText("http://"+url_new);
}
}
I am Currently working with webview in which Javascript popup is created when some button is clicked in webview. But it is not opening in my Webview.
My code is Here:
wvPayements = (WebView) view.findViewById(R.id.wvPaymentsPage);
wvPayements.getSettings().setLoadWithOverviewMode(true);
wvPayements.getSettings().setUseWideViewPort(true);
wvPayements.getSettings().setSupportZoom(true);
wvPayements.getSettings().setAllowFileAccess(true);
wvPayements.getSettings().setJavaScriptEnabled(true);
wvPayements.getSettings()
.setJavaScriptCanOpenWindowsAutomatically(true);
wvPayements.getSettings().setBuiltInZoomControls(true);
wvPayements.setWebViewClient(new WebViewClient() {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return true;
}
#Override
public void onPageFinished(WebView view, final String url) {
dialog.cancel();
}
});
wvPayements
.loadUrl("http://192.168.0.114/Parch_ws/testalert.html");
You have to use WebChromeClient for your purpose:
One should use a WebChromeClient to get these alerts and the
functionality can be overwritten using theonJsAlert() method. Hope
this helps!
WebView wv=new WebView(this);
wv.setWebChromeClient(new WebChromeClient() {
#Override
public boolean onJsAlert(WebView view, String url, String message, JsResult result) {
//Required functionality here
return super.onJsAlert(view, url, message, result);
}
});

This can also happen if you are executing ES6 on unsupported browsers.
You can always check supported versions here
I have loaded a web page in WebView via WebView.loadData().
Now I want to ad custom action to a button of that webpage from the WebView (Like, when I click the button, it will behave differently from the original webpage).
Is it possible from WebView? If possible, how can I do that?
Yes, it is possible. You can try something like this
public class myWebClient extends WebViewClient
{
#Override
public void onPageStarted(WebView view, String url, Bitmap favicon)
{
super.onPageStarted(view, url, favicon);
}
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url)
{
if(url.equalsIgnoreCase("your url"))
{
// your code
return true;
}
return false;
}
#Override
public void onPageFinished(WebView view, String url)
{
super.onPageFinished(view, url);
}
}
Don't forget to add myWebClient to your webView
No, it's no possible. You can only webView.setWebViewClient(new CustomWebClient());
private class CustomWebClient extends WebViewClient {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
if(url...) // your logic here
return true;
}
