I have a WebView in my application and I do a search on google. When I click a link there, let's say stackoverflow.com, it redirects me to a white page and the url is about:blank (new tab?).
I already tried this
webview.setWebViewClient(new WebViewClient() {
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return false;
}
});
but it does not have any effect on this behaviour. Can anyone help me?
I just fixed it with this post here
#Override
public void onPageFinished(WebView view, String url)
{
System.out.println("onPageFinished: " + url);
if ("about:blank".equals(url) && view.getTag() != null)
{
view.loadUrl(view.getTag().toString());
}
else
{
view.setTag(url);
}
}
That normally happens while accessing https URLs which have untrusted certificates. Have you tried this yet?
webview.setWebViewClient(new WebViewClient() {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return false;
}
#Override
public void onReceivedSslError(WebView view, SslErrorHandler handler, SslError error) {
handler.proceed(); // Ignore SSL certificate errors
}
});

I'm using an URL in webview, when I click a link it should direct it to a custom url like paynow://xxxxx.
When I use the webview client it is coming sometimes and not redirect sometime.
Is there any wrong in my code.
please check the url onPageStarted and shouldOverrideUrlLoading
protected void onCreate(#Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
context=this;
MainApplication.getComponent(this).inject(this);
back=findViewById(R.id.back_w);
front=findViewById(R.id.right_w);
wv1=(WebView)findViewById(R.id.webview);
wv1.getSettings().setLoadsImagesAutomatically(true);
wv1.getSettings().setJavaScriptEnabled(true);
wv1.setWebViewClient(new MyBrowser());
wv1.setWebChromeClient(new WebChromeClient());
wv1.setScrollBarStyle(View.SCROLLBARS_INSIDE_OVERLAY);
wv1.loadUrl(Constants.Load_url);
}
private class MyBrowser extends WebViewClient {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return true;
}
#RequiresApi(api = Build.VERSION_CODES.LOLLIPOP)
#Override
public boolean shouldOverrideUrlLoading(WebView view, WebResourceRequest request) {
final Uri uri = request.getUrl();
return super.shouldOverrideUrlLoading(view, uri.toString());
}
#Override
public void onPageStarted(WebView view, String url, Bitmap favicon) {
super.onPageStarted(view, url, favicon);
if (url.startsWith("paynow://"))
{
if (url.contains("order"))
{
startActivityForResult(new Intent(context,TipsActivity.class).putExtra("url",url),1);
}
}
}
#Override
public void onPageFinished(WebView view, String url) {
super.onPageFinished(view, url);
}
#Override
public void onReceivedError(WebView view, WebResourceRequest request, WebResourceError error) {
super.onReceivedError(view, request, error);
wv1.setVisibility(View.GONE);
}
}
Answer:
WebView is blocking popup which redirect to custom url
by adding wv1.getSettings().setPluginState(WebSettings.PluginState.ON); it worked
You need to move the logic in onPageStarted to the shouldOverrideUrlLoading functions.

I am using a webview in my android app. Now the issue is in that webview it is opening like a desktop site not like a mobile platform site.
As for example, when I open the page in webview it is being shown like
And the same page when I am opening in web browser it looks like;
Now my question is I want to open the page in my web view like it is in web browser and I have no idea why it is behaving like that.
My webview code is like;
final WebView webview = (WebView)vi.findViewById(R.id.webview);
WebSettings set = webview.getSettings();
set.setJavaScriptEnabled(true);
set.setBuiltInZoomControls(true);
set.setJavaScriptEnabled(true);
set.setDomStorageEnabled(true);
set.setLoadWithOverviewMode(true);
set.setUseWideViewPort(true);
set.setSaveFormData(true);
set.setJavaScriptCanOpenWindowsAutomatically(true);
set.setBuiltInZoomControls(true);
set.setDisplayZoomControls(false);
set.setSupportZoom(false);
set.setDefaultTextEncodingName("utf-8");
WebChromeClient webClient = new WebChromeClient(){
public void onCloseWindow(Window w){
super.onCloseWindow(webview);
System.out.println("Closed");
}
};
webview.setWebChromeClient(webClient);
webview.setWebViewClient(new WebViewClient(){
#Override
public void onReceivedError(WebView view, int errorCode, String description, String failingUrl)
{
// Handle the error
}
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url)
{
view.loadUrl(url);
return true;
}
#Override
public void onPageFinished(WebView view, String url) {
dialog.dismiss();
}
});
webview.setInitialScale(1);
webview.getSettings().setJavaScriptEnabled(true);
webview.getSettings().setLoadWithOverviewMode(true);
webview.loadUrl(url);
I changed the value of webview.setInitialScale(1); but no luck so far.
I can not change the HTML of the pages, so I need to do some kind of changes in webview end.
N.B. The attached images of page is same HTML page opening in browser and webview. PLEASE IGNORE THE BACKGROUND COLOR.
Any help will be very good for me. Thanks in advance.
This works for me
public class MainActivity extends AppCompatActivity {
private WebView webView;
#Override
protected void onCreate(Bundle savedInstanceState) {
getWindow().requestFeature(Window.FEATURE_PROGRESS);
setContentView(R.layout.activity_main);
super.onCreate(savedInstanceState);
initViews();
}
protected void initViews() {
webView = (WebView) findViewById(R.id.webView);
if (Build.VERSION.SDK_INT >= 19) {
webView.setLayerType(View.LAYER_TYPE_HARDWARE, null);
} else {
webView.setLayerType(View.LAYER_TYPE_SOFTWARE, null);
}
webView.getSettings().setJavaScriptEnabled(true);
webView.getSettings().setDomStorageEnabled(true);
webView.getCertificate();
webView.setWebViewClient(new SSLTolerantWebViewClient());
webView.loadUrl("https://www.google.com");
}
private class SSLTolerantWebViewClient extends WebViewClient {
// ProgressBar progressBar = (ProgressBar) findViewById(R.id.progress_bar);
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
Log.d("ddd", "ddd");
return true;
}
#Override
public void onPageFinished(WebView view, String url) {
super.onPageFinished(view, url);
// progressBar.setVisibility(View.GONE);
}
#Override
public void onPageStarted(WebView view, String url, Bitmap favicon) {
super.onPageStarted(view, url, favicon);
// progressBar.setVisibility(View.VISIBLE);
}
#Override
public void onReceivedSslError(WebView view, final SslErrorHandler handler, SslError error) {
handler.proceed();
}
}
}
Is your page responsive ? Try opening page in mobile browser. if it is not responsive make it responsive. Make sure you have added viewport meta tag in html like -
yes I searched the site and didn't find something that helps me
because every one are saying use "shouldOverrideUrlLoading"
but that's not helping me - its not working
I am trying to open - In the same page an URL that supposed to open a new page link, but when I press it - nothing happens
I am using it as a fragment
public class FlightFragment extends Fragment {
private WebView webView;
public FlightFragment(){};
private String currentUrl;
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
View rootView = inflater.inflate(R.layout.flight_fragment,container,false);
currentUrl = "https://flights.travelor.me/?locale=he";
webView = (WebView)rootView.findViewById(R.id.flightweb);
WebViewClient MyWebViewClient= new WebViewClient();
MyWebViewClient.shouldOverrideUrlLoading(webView, currentUrl);
ourWebViewClient(currentUrl);
webView.getSettings().setLoadsImagesAutomatically(true);
webView.getSettings().setJavaScriptCanOpenWindowsAutomatically(true);
webView.setScrollBarStyle(View.SCROLLBARS_INSIDE_OVERLAY);
webView.setWebViewClient(new FlightFragment.MyBrowser());
webView.getSettings().setUseWideViewPort(true);
webView.getSettings().setLoadWithOverviewMode(true);
webView.getSettings().setSupportZoom(true);
webView.getSettings().setBuiltInZoomControls(true);
webView.getSettings().setDisplayZoomControls(false);
webView.getSettings().setSupportMultipleWindows(true);
webView.getSettings().setDomStorageEnabled(true);
webView.getSettings().setJavaScriptEnabled(true);
webView.setOnKeyListener(new View.OnKeyListener() {
#Override
public boolean onKey(View view, int i, KeyEvent keyEvent) {
if (keyEvent.getAction() == keyEvent.ACTION_DOWN) {
if (webView.canGoBack()) {
webView.goBack();
return true;
}
}
return false;
}
});
webView.loadUrl(currentUrl);
return rootView;
}
public void ourWebViewClient(String currentUrl) {
this.currentUrl = currentUrl;
}
private class MyBrowser extends WebViewClient {
#SuppressWarnings("deprecation")
#TargetApi(Build.VERSION_CODES.N)
#Override
public boolean shouldOverrideUrlLoading(WebView view, WebResourceRequest request) {
if (request.equals(currentUrl)) {
view.loadUrl(request.getUrl().toString());
}
return true;
}
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
if (url.equals(currentUrl)) {
view.loadUrl(url);
}
return true;
}
}
}
You are returning false when your url is intercepted, try changing like this
webView.setWebViewClient(new WebViewClient() {
class MyWebViewClient extends WebViewClient {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
if (url.equals(currentUrl)) {
Intent intent=new Intent(CurrentActivity.this,NewActivity.class);
intent.putExtra("url to load in NewActivity",url);
startActivity(intent); //get this url using getextra in new activity
}
}
}});
If your target version is >= 26
then override both the function below
#TargetApi(Build.VERSION_CODES.N)
#Override
public boolean shouldOverrideUrlLoading(WebView view, WebResourceRequest request)
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url)
Because shouldOverrideUrlLoading(WebView view, String url) is deprecated since Android N. Write the code for Android N and above in the first override method.
In your code remove this
webView.setWebViewClient(new WebViewClient() {
class MyWebViewClient extends WebViewClient {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
if (url.equals(currentUrl)) {
return false;
}
view.loadUrl(url);
return true;
}
}});
as you are setting your WebViewClient again below this code and change your MyBrowser class
private class MyBrowser extends WebViewClient {
#SuppressWarnings("deprecation")
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return true;
}
#TargetApi(Build.VERSION_CODES.N)
#Override
public boolean shouldOverrideUrlLoading(WebView view, WebResourceRequest request) {
view.loadUrl(request.getUrl().toString());
return true;
}
}
#golan Try to make your Webview fragment as a Activity which will work like a generic view and will open web pages as per requirement based on input url.
shouldOverrideUrlLoading loading method will required if you want to check the input urls.
Do all required web settings like
WebSettings webSettings = webviewBinding.detailWebView.getSettings();
webSettings.setJavaScriptEnabled(true);
webSettings.setDisplayZoomControls(false);
webSettings.setLoadWithOverviewMode(false);
webSettings.setUseWideViewPort(true);
webSettings.setSupportZoom(true);
Override onBackPressed() method with following code:
if (detailWebView.canGoBack()) {
detailWebView.goBack();
}
else {
super.onBackPressed();
}
The canGoBack() will allow you to go back upto all web pages and if no more pages to go back it will redirect to you to last loaded activity or view.
I need to get a url when user press somethings in a webview.
I use this code:
webView = (WebView) rootView.findViewById(R.id.webView);
WebSettings webSettings = webView.getSettings();
webSettings.setJavaScriptEnabled(true);
webView.loadUrl("my url");
webView.setWebViewClient(new MyWebClient());
MyWebClien
private class MyWebClient extends WebViewClient {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
Log.e("URL", url);
return true;
}
}
But, if i click something, the event is never called.
Thank you
shouldOverrideUrlLoading(WebView view, String url) will get called on clicking a link on a webview.
usage example:
webView.setWebViewClient(new WebViewClient() {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
try {
// do whatever you want to do on a web link click
} catch (Exception e) {
e.printStackTrace();
}
return false;
}
});
webView.loadUrl("url to open first webpage on a webview");
Based on this: how to get the current page url from the web view in android
WebView webview = new WebView(context);
webview.setWebViewClient(new WebViewClient()
{
#Override
public void onPageStarted(WebView view, String url, Bitmap favicon) {
super.onPageStarted(view, url, favicon);
System.out.println("your current url when webpage loading.." + url);
}
#Override
public void onPageFinished(WebView view, String url) {
System.out.println("your current url when webpage loading.. finish" + url);
super.onPageFinished(view, url);
}
#Override
public void onLoadResource(WebView view, String url) {
// TODO Auto-generated method stub
super.onLoadResource(view, url);
}
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
System.out.println("when you click on any interlink on webview that time you got url :-" + url);
return super.shouldOverrideUrlLoading(view, url);
}
});
My code below loads a progress dialogue into webview on the initial load but I'd like it to appear every time webview is loading a URL!
I think I need to use onpagestarted() before the progressbar but I'm a bit of a noob at all this and having trouble getting it working. Can anyone advise please?
//need to set progress bar condition here!
progressBar = ProgressDialog.show(MyActivity.this, "Loading title", "Loading...");
myWebView.setWebViewClient(new WebViewClient() {
public void onPageFinished(WebView view, String url) {
Log.i(TAG, "Finished loading URL: " +url);
if (progressBar.isShowing()) {
progressBar.dismiss();
}
}
});
//web site load
myWebView.loadUrl("http://www.google.com");
boolean loadingFinished = true;
boolean redirect = false;
mWebView.setWebViewClient(new WebViewClient() {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String urlNewString) {
if (!loadingFinished) {
redirect = true;
}
loadingFinished = false;
webView.loadUrl(urlNewString);
return true;
}
#Override
public void onPageStarted(WebView view, String url) {
loadingFinished = false;
//SHOW LOADING IF IT ISNT ALREADY VISIBLE
}
#Override
public void onPageFinished(WebView view, String url) {
if(!redirect){
loadingFinished = true;
}
if(loadingFinished && !redirect){
//HIDE LOADING IT HAS FINISHED
} else{
redirect = false;
}
}
});
As shown here: How to listen for a WebView finishing loading a URL?
You should use the onPageStarted() method to show the ProgressDialog:
myWebView.setWebViewClient(new WebViewClient() {
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return false;
}
public void onPageStarted(WebView view, String url, Bitmap favicon) {
progressBar.show();
}
public void onPageFinished(WebView view, String url) {
progressBar.hide();
}
});
