Android WebView failed to load a particular URL - android

I am working on a android project. In that project i have to load a URL in WebView.
But I am unable to Load the particular URL (Any other URL is loading perfectly). I have also added INTERNET permission. Though the URL open from Android browser .
public class MainActivity extends Activity {
private WebView webView;
private ProgressDialog progDailog;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
webView = (WebView)findViewById(R.id.webview1);
progDailog = ProgressDialog.show(this, "Loading","Please wait...", true);
progDailog.setCancelable(false);
webView = (WebView) findViewById(R.id.webview1);
webView.getSettings().setJavaScriptEnabled(true);
webView.getSettings().setLoadWithOverviewMode(true);
webView.getSettings().setUseWideViewPort(true);
// webView.setWebChromeClient(new WebChromeClient());
webView.setWebViewClient(new WebViewClient(){
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
progDailog.show();
view.loadUrl(url);
return true;
}
#Override
public void onPageFinished(WebView view, final String url) {
progDailog.dismiss();
}
});
webView.loadUrl("https://XXXXX.com/");
}
}

Web View not working with some specific url

public class MainActivity extends AppCompatActivity {
String url = "https://www.pinterest.com";
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
WebView webView = findViewById(R.id.webview);
webView.getSettings().setJavaScriptEnabled(true);
webView.getSettings().setLoadWithOverviewMode(true);
webView.getSettings().setUseWideViewPort(true);
webView.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) {
}
});
webView.loadUrl(url);
}
}
Web View is not loading "https://www.pinterest.com" within the application but it was working with chrome browser using intent. I tried of other urls it's working. While loading "https://www.pinterest.com" using webview, getting the output screen like below

You try this:
WebSettings settings = webView.getSettings();
settings.setJavaScriptEnabled(true);
settings.setAllowContentAccess(true);
settings.setDomStorageEnabled(true);
webView.setWebViewClient(new WebViewClient());
webView.loadUrl("https://www.pinterest.com/");
In manifest:
android:hardwareAccelerated="true"

set the JavascriptEnabled and AllowContentAccess and setDomStorageEnabled to true in settings

Access remote pdf file with login (authentication)

I am facing problem with loading URL in web-view. Web-view shows blank because it is not logged in. How to access course file without login into moodle2.6 by using url.
Using this url format
http://example.com/pluginfile.php/4418/mod_resource/content/10/xx-t2.pdf
Here is my web-view code
webView.setWebViewClient(new WebViewClient(){
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
//progDailog.show();
view.loadUrl(url);
return true;
}
#Override
public void onPageFinished(WebView view, final String url) {
//progDailog.dismiss();
}
});
webView.loadUrl("http://example.com/pluginfile.php/4418/mod_resource/content/10/xx-t2.pdf");

You need to append the pdf URL to Google Doc Viewer to open pdf in web view, Also you will need to enable JavaScript for your webview
public class MainActivity extends AppCompatActivity {
WebView webview;
String pageURL = "https://developer.android.com/guide/webapps/webview.html";
String pdf = "http://unec.edu.az/application/uploads/2014/12/pdf-sample.pdf"; //your pdf address
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
webview = findViewById(R.id.webview);
WebSettings webSettings = webview.getSettings();
webSettings.setJavaScriptEnabled(true);
webview.getSettings().setJavaScriptEnabled(true); // enable javascript
webview.setWebViewClient(new WebViewClient() {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
//progDailog.show();
view.loadUrl(url);
return true;
}
#Override
public void onPageFinished(WebView view, final String url) {
//progDailog.dismiss();
}
});
//webview.loadUrl(pageURL);
webview.loadUrl("http://drive.google.com/viewerng/viewer?embedded=true&url=" + pdf); //simply append pdf address to doc viewer
}
}
Sample PDF opened in webview

It seems that you're webclient is not calling their super methods, which could be one reason for the page to not load, use the following code to load the login page, which once signed in the user could view the intended pdf file.
webView.setWebViewClient(new WebViewClient(){
#Override
public void onPageFinished(WebView view, String url) {
super.onPageFinished(view, url);//<-- this is important when overriding
}
#Override
public void onPageStarted(WebView view, String url, Bitmap favicon) {
super.onPageStarted(view, url, favicon);//<-- this is important when overriding
}
});
webView.loadUrl("https://lms.jsbl.com//pluginfile.php//4925//mod_resource//content//0//calendar_cal_605.pdf");
And also If you want you view a pdf using the webview you need append the following before your url so that the google plugin could be used to load the pdf
https://docs.google.com/gview?embedded=true&url=
(for this to work make sure you have added the following to your webview
webView.getSettings().setJavaScriptEnabled(true);webView.getSettings().setPluginState(PluginState.ON);)
According to this question some login form submit might not work on android webview so set all/some(check if your login works without it) on your webview to make the login work
mWebView.getSettings().setJavaScriptEnabled(true);
mWebView.getSettings().setDomStorageEnabled(true);
mWebView.getSettings().setDatabaseEnabled(true);
mWebView.getSettings().setDatabasePath(dbpath); //check the documentation for info about dbpath
mWebView.getSettings().setMinimumFontSize(1);
mWebView.getSettings().setMinimumLogicalFontSize(1);
But if you know the credentials for the login You could follow the instruction on this site to inject a javascript to the webview which would fire the Login form submit on the webview and redirect to the pdf file directly
UPDATE 16/3/2018
Use the following code which will append the google pdf widget during a redirect
and has a pdf extension
boolean isInititialRedirectComplete = false;
boolean isPdfRedirectComplete = false;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
f-inal WebView webView = (WebView) findViewById(R.id.testWebView);
webView.getSettings().setJavaScriptEnabled(true);webView.getSettings().setPluginState(WebSettings.PluginState.ON);
webView.setWebViewClient(new WebViewClient(){
#Override
public void onPageFinished(WebView view, final String url) {
super.onPageFinished(view, url);
if (url.substring(url.lastIndexOf(".")).equalsIgnoreCase(".pdf") && !isPdfRedirectComplete && isInititialRedirectComplete ){
isPdfRedirectComplete = true;
webView.loadUrl("https://docs.google.com/gview?embedded=true&url=" + url);
}
isInititialRedirectComplete = true;
}
});
webView.loadUrl(
"https://lms.jsbl.com//pluginfile.php//4925//mod_resource//content//0//calendar_cal_605.pdf");
}

Progress Till Web View Loads Web Page

In my application web view takes time to load few webpages.. Is it possible to show progress till web view loads web page. I am using below code to load web page
WebView wv = (WebView) findViewById(R.id.webView);
wv.setWebViewClient(new MyBrowser());
String url = "http://somesites.com";
wv.getSettings().setLoadsImagesAutomatically(true);
wv.getSettings().setJavaScriptEnabled(true);
wv.setScrollBarStyle(View.SCROLLBARS_INSIDE_OVERLAY);
wv.loadUrl(url);

For showing progress bar use this method in oncreateview in Activity :
private WebView web;
private KProgressHUD pDialog;
private void setPages() {
web = (WebView) findViewById(R.id.web);
// you can use progressbar or progressdialog or any other
// progressview here
pDialog = KProgressHUD.create(activity)
.setStyle(KProgressHUD.Style.SPIN_INDETERMINATE)
.setDimAmount(0.5f);
pDialog.setCancellable(true);
pDialog.show();
web.getSettings().setSupportZoom(true);
web.getSettings().setBuiltInZoomControls(true);
web.setWebViewClient(new WebViewClient() {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
return super.shouldOverrideUrlLoading(view, url);
}
#Override
public void onPageFinished(WebView view, String url) {
super.onPageFinished(view, url);
pDialog.dismiss();
}
});
web.loadUrl(YOUR_URL_HERE);
}

Android WebViewClient - Load follow redirect after Login (Joomla)

I've built up a Joomla site and want this show/load in a WebView. After login in Joomla follows a redirect, this is not displayed in the WebView. Is there a simple way, you have an example perhaps?
public class MainActivityWebbrowser extends Activity {
private WebView webView;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main_activity_webbrowser);
webView = (WebView) findViewById(R.id.webView);
webView.getSettings().setJavaScriptEnabled(true);
webView.getSettings().setDomStorageEnabled(true);
webView.loadUrl("https://www.example.com/");
webView.setWebViewClient(new WebViewClient() {
public boolean shouldOverrideUrlLoading(WebView viewx, String urlx) {
viewx.loadUrl("https://www.example.com/");
return super.shouldOverrideUrlLoading(viewx, urlx);
}
});
return;
}

Android - Open URL in a WebView [duplicate]

I created an Activity that has a title and a web view in a LinearLayout. In the onResume() method it calls webView.loadUrl(url). The problem is that the activity first shows the title with the rest of the screen blank, then the device browser is launched with the page for the URL. What I want to see is the page being shown in the WebView below the title. What could be the problem?
Edit:
Ok, did some further search and found this one:
Clicking URLs opens default browser
It points to the WebView tutorial here.
Just implement the web client and set it.

Answering my question based on the suggestions from Maudicus and Hit.
Check the WebView tutorial here.
Just implement the web client and set it before loadUrl. The simplest way is:
myWebView.setWebViewClient(new WebViewClient());
For more advanced processing for the web content, consider the ChromeClient.

Use this:
lWebView.setWebViewClient(new WebViewClient());

use like this:
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_dedline);
WebView myWebView = (WebView) findViewById(R.id.webView1);
myWebView.setWebViewClient(new WebViewClient());
myWebView.loadUrl("https://google.com");
}

Make your Activity like this.
public class MainActivity extends Activity {
WebView browser;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
// find the WebView by name in the main.xml of step 2
browser=(WebView)findViewById(R.id.wvwMain);
// Enable javascript
browser.getSettings().setJavaScriptEnabled(true);
// Set WebView client
browser.setWebChromeClient(new WebChromeClient());
browser.setWebViewClient(new WebViewClient() {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return true;
}
});
// Load the webpage
browser.loadUrl("http://google.com/");
}
}

I was facing the same problem and I found the solution
Android's official Documentation about WebView
Here is my onCreateView() method and here i used two methods to open the urls
Method 1 is opening url in Browser and
Method 2 is opening url in your desired WebView.
And I am using Method 2 for my Application and this is my code:
public class MainActivity extends Activity {
private WebView myWebView;
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.fragment_webpage_detail, container, false);
// Show the dummy content as text in a TextView.
if (mItem != null) {
/* Method : 1
This following line is working fine BUT when we click the menu item then it opens the URL in BROWSER not in WebView */
//((WebView) rootView.findViewById(R.id.detail_area)).loadUrl(mItem.url);
// Method : 2
myWebView = (WebView) rootView.findViewById(R.id.detail_area); // get your WebView form your xml file
myWebView.setWebViewClient(new WebViewClient()); // set the WebViewClient
myWebView.loadUrl(mItem.url); // Load your desired url
}
return rootView;
} }

Try this code...
private void startWebView(String url) {
//Create new webview Client to show progress dialog
//When opening a url or click on link
webView.setWebViewClient(new WebViewClient() {
ProgressDialog progressDialog;
//If you will not use this method url links are opeen in new brower not in webview
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return true;
}
//Show loader on url load
public void onLoadResource (final WebView view, String url) {
if (progressDialog == null) {
// in standard case YourActivity.this
progressDialog = new ProgressDialog(view.getContext());
progressDialog.setMessage("Loading...");
progressDialog.show();
}
}
public void onPageFinished(WebView view, String url) {
try{
if (progressDialog.isShowing()) {
progressDialog.dismiss();
progressDialog = null;
}
}catch(Exception exception){
exception.printStackTrace();
}
}
});
// Javascript inabled on webview
webView.getSettings().setJavaScriptEnabled(true);
// Other webview options
/*
webView.getSettings().setLoadWithOverviewMode(true);
webView.getSettings().setUseWideViewPort(true);
webView.setScrollBarStyle(WebView.SCROLLBARS_OUTSIDE_OVERLAY);
webView.setScrollbarFadingEnabled(false);
webView.getSettings().setBuiltInZoomControls(true);
*/
/*
String summary = "<html><body>You scored <b>192</b> points.</body></html>";
webview.loadData(summary, "text/html", null);
*/
//Load url in webview
webView.loadUrl(url);
}

If you see an empty page, enable JavaScript.
webView.setWebViewClient(new WebViewClient());
WebSettings webSettings = webView.getSettings();
webSettings.setJavaScriptEnabled(true);
webSettings.setDomStorageEnabled(true);
webView.loadUrl(url);

Simply Answer you can use like this
public class MainActivity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
WebView webView = new WebView(this);
setContentView(webView);
webView.setWebViewClient(new WebViewClient());
webView.loadUrl("http://www.google.com");
}
}

If you're using webChromeClient I'll suggest you to use webChromeClient and webViewClient together. because webChromeClient does not provides shouldOverrideUrlLoading. It is okay to use both.
webview.webViewClient = WebViewClient()
webview.webChromeClient = Callback()
private inner class Callback : WebChromeClient() {
override fun onProgressChanged(view: WebView?, newProgress: Int) {
super.onProgressChanged(view, newProgress)
if (newProgress == 0) {
progressBar.visibility = View.VISIBLE
} else if (newProgress == 100) {
progressBar.visibility = View.GONE
}
}
}

I just found out that it depends on the formatting of the URL:
https://example.com/example gets opened in the browser
https://example.com/example/ (with / at the end) gets opened in the webView
My code just uses
webview.loadUrl(url)
no need to set
webView.setWebViewClient(new WebViewClient())
at least in my case.
Maybe that's useful for some of you.

My problem ended up being that I needed to do a clearHistory before I could switch between sites without opening an external browser.
#Override
public void onPageFinished(WebView view, String url) {
webView_.clearHistory();
super.onPageFinished(webView_, url);
}
