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);
}

Not able to open url in webview

When I load url it shows a window to select browser. For ex. - If I want to open "http://www.facebook.com/" then it show me window to choose chrome or default browser. I am not able to understand why this is happening.
Actually in below code if i successfully got url from server then I hide a sorry image and show webview. Otherwise I show webview and hide sorry image.
webView = (WebView) findViewById(R.id.webView);
webView.setVisibility(View.VISIBLE);
ImageView img = (ImageView) findViewById(R.id.image);
img.setVisibility(View.GONE);
webView.setInitialScale(1);
webView.getSettings().setJavaScriptEnabled(true);
webView.getSettings().setLoadWithOverviewMode(true);
webView.getSettings().setUseWideViewPort(true);
webView.setScrollBarStyle(WebView.SCROLLBARS_OUTSIDE_OVERLAY);
webView.setScrollbarFadingEnabled(false);
webView.loadUrl("http://www.facebook.com/");

Try to add this line
webView.setWebViewClient(new WebViewClient());

Add a WebViewClient like this
public class myWebClient extends WebViewClient
{
#Override
public void onPageStarted(WebView view, String url, Bitmap favicon) {
// TODO Auto-generated method stub
super.onPageStarted(view, url, favicon);
}
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
// TODO Auto-generated method stub
view.loadUrl(url);
return true;
}
}
You should override your shouldOverrideUrlLoading() method.
In your UI activity add this line
web.setWebViewClient(new myWebClient());
It will solve your problem. Hope it helps!

Firstly, replace http with https and then in a order to do this, you need to first create a new java class that extends the WebViewClient class and overrides the onPageFinished method like this:
public class CustomWebViewClient extends WebViewClient
{
#Override
public void onPageFinished(WebView view, String url) {
//https://www.facebook.com/dialog/permissions.request
//actually works for me, but I put the URL you say is coming up
//blank in there instead, whatever works for you:
if(url.startsWith("https://www.facebook.com/dialog/oauth")){
String redirectUrl = "http://www.yourdomain.com/MyApp/";
view.loadUrl(redirectUrl);
return;
}
super.onPageFinished(view, url);
}
}
Second, just add it to your WebView:
webview.setWebViewClient(new CustomWebViewClient());

Android WebView failed to load a particular URL

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/");
}
}

Can not acess url that are present in the html files from Webview in Android

I am trying to access the url using the shouldOverrideUrlLoading method. For some reason when I try to access the url that are present in the html files, I get Web page not available error.Previously I could access the url because I stored my html file in the raw folder but I needed to move it to assets folder as the code looks cleaner this way. This is my code, could anyone let me know how I can resolve this.
webview.setWebChromeClient(new WebChromeClient());
webview.setWebViewClient(new WebViewClient());
webview.loadUrl("file:///android_asset/myfile/file.html");
webview.setVerticalScrollBarEnabled(false);
webview.setWebViewClient(new WebViewClient()
{
public boolean shouldOverrideUrlLoading(WebView view, String url) {
if (url.equalsIgnoreCase("some text")){
setDialog("some fancy text");
}

Try to get the Real Path of the file first and then try as your way like this:
String YourURI="/android_asset/myfile/file.html";
YourURI = new File(getRealPathFromURI(YourURI));
//Got the Real Path Of the File
private String getRealPathFromURI(Uri contentURI) {
Cursor cursor = getContentResolver().query(contentURI, null, null, null, null);
cursor.moveToFirst();
int idx = cursor.getColumnIndex(MediaStore.Images.ImageColumns.DATA);
return cursor.getString(idx);
}
webview.setWebChromeClient(new WebChromeClient());
webview.setWebViewClient(new WebViewClient());
webview.loadUrl(YourURI); //**Used the Real Path**
webview.setVerticalScrollBarEnabled(false);
webview.setWebViewClient(new WebViewClient()
{
public boolean shouldOverrideUrlLoading(WebView view, String url) {
if (url.equalsIgnoreCase("some text")){
setDialog("some fancy text");
}
}
If the File is in the SDCARD :-
webview.setWebChromeClient(new WebChromeClient());
webview.setWebViewClient(new WebViewClient());
if (!Environment.getExternalStorageState().equals(Environment.MEDIA_MOUNTED))
{
Log.d(TAG, "No SDCARD");
}
else
{
webview.loadUrl("file://"+Environment.getExternalStorageDirectory()
+"/android_asset/myfile/file.html");
}
webview.setVerticalScrollBarEnabled(false);
webview.setWebViewClient(new WebViewClient()
{
public boolean shouldOverrideUrlLoading(WebView view, String url) {
if (url.equalsIgnoreCase("some text")){
setDialog("some fancy text");
}
}
Final Edit:- This Code Works Perfectly for Asset Folder
public class MyActivity extends Activity {
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.webview);
WebView webview;
webview = (WebView) findViewById(R.id.webView1);
webview.loadUrl("file:///android_asset/myfile/file.html");
}
}

There is another way that would also work for you---
webView.loadData(customHtml, "text/html", "UTF-8");
where custromHtml is the HTML line that is used to be displayed.
on the place of "custromHtml" you just pass "file://android_asset/myfile/file.html".
I think this should work.

You may try for this too -
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
String myURL = "file:///android_asset/index.html";
myBrowser=(WebView)findViewById(R.id.mybrowser);
/*By default Javascript is turned off,
* it can be enabled by this line.
*/
myBrowser.getSettings().setJavaScriptEnabled(true);
myBrowser.setWebViewClient(new WebViewClient());
myBrowser.loadUrl(myURL);
}
and also check you have placed the file in correct folder of main project. If all this is ok, make a clean project and fix project. Then try to run it.

public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
String myURL = "file:///android_asset/index.html";
myBrowser=(WebView)findViewById(R.id.mybrowser);
myBrowser.getSettings().setJavaScriptEnabled(true);
myBrowser.setWebViewClient(new WebViewClient());
myBrowser.loadUrl(myURL);
}

This would work well try it-----
"android.resource://[package]/[res type]/[res name]"
Uri path = Uri.parse("android.resource://com.androidbook.samplevideo/raw/myvideo");

Loading an Android Resource into a WebView

shouldOverrideUrlLoading does not work on ICS for file://, but works for fine for external urls. loadURL works fine loading from the assets folder.
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
WebView web=(WebView)findViewById(R.id.webView1);
web.setWebViewClient(new MyWebClient());
//web.loadUrl("file:///android_asset/index.html");
web.loadUrl("http://google.com");
.....
class MyWebClient extends WebViewClient
{
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
Log.d("MyWebClient", "url is: " + url);
if (url.equalsIgnoreCase("google.com")){
Log.d("MyWebClient","url is: " + url);
}
return false;
}
}

I found this forum solution which solved the problem for me: http://www.cynosurex.com/Forums/DisplayComments.php?file=Java/Android/Android_4_has_a_.file....android_asset.webkit.._bug

I think you should try this ....
webview.setWebChromeClient(new WebChromeClient());
webview.setWebViewClient(new WebViewClient());
webview.loadUrl("file://android_asset/myfile/file.html");
webview.setVerticalScrollBarEnabled(false);
webview.setWebViewClient(new WebViewClient()
{
public boolean shouldOverrideUrlLoading(WebView view, String url) {
if (url.equalsIgnoreCase("some text")){
setDialog("some fancy text");
}

How to get loaded web page title in Android WebView?

I'm using a WebView in my application, I have a requirement to change the app title based on the page user is on. How can I do this in Android WebView?
I did this in iphone by following line
self.title = [webPage stringByEvaluatingJavaScriptFromString:#"document.title"]
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// Adds Progrss bar Support
this.getWindow().requestFeature(Window.FEATURE_PROGRESS);
setContentView(R.layout.webview );
// Makes Progress bar Visible
getWindow().setFeatureInt( Window.FEATURE_PROGRESS, Window.PROGRESS_VISIBILITY_ON);
mWebView = (WebView) findViewById( R.id.webview ); //This is the id you gave
//to the WebView in the main.xml
mWebView.getSettings().setJavaScriptEnabled(true);
mWebView.getSettings().setSupportZoom(true); //Zoom Control on web (You don't need this
//if ROM supports Multi-Touch
mWebView.getSettings().setBuiltInZoomControls(true); //Enable Multitouch if supported by ROM
// Load URL
Bundle b = getIntent().getExtras();
String url = b.getString("url");
Log.d(TAG, "url " + url);
mWebView.loadUrl(url);
// Sets the Chrome Client, and defines the onProgressChanged
// This makes the Progress bar be updated.
mWebView.setWebChromeClient(new WebChromeClient() {
public void onProgressChanged(WebView view, int progress){
//Make the bar disappear after URL is loaded, and changes string to Loading...
myActivity.setTitle("Loading...");
myActivity.setProgress(progress * 100); //Make the bar disappear after URL is loaded
// Return the app name after finish loading
if(progress == 100)
myActivity.setTitle(R.string.app_name);
}
});
mWebView.setWebViewClient(new WebViewClient(){
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return true;
// return super.shouldOverrideUrlLoading(view, url);
}
#Override
public void onLoadResource(WebView view, String url) {
// TODO Auto-generated method stub
super.onLoadResource(view, url);
}
#Override
public void onPageFinished(WebView view, String url) {
super.onPageFinished(view, url);
ImageView logoImageView = (ImageView)findViewById(R.id.logoimage);
logoImageView.setVisibility(View.GONE);
Log.d(TAG, "view.getTitle() " + view.getTitle());
myActivity.setTitle(view.getTitle());
}
});
}

You'll have to use a custom WebViewClient to get this done.
You will override the onPageFinished() method so when a new page finishes loading you can set the webview to the appropriate title.
Below is a sample implementation of the above:
WebView mWebView = (WebView) findViewById(R.id.mwebview);
mWebView.setWebViewClient(new WebViewClient() {
#Override
public void onPageFinished(WebView view, String url) {
ExperimentingActivity.this.setTitle(view.getTitle());
}
});
You're a going to do that where you're initializing your webview.
Replace the "ExperimentingActivity" to whatever you activity's name is.
If you're already overriding the WebViewClient, just add this function or the code inside to your already existing function.
You can get more info on the classes and functions I'm using here at:
Android Developers: Activity - setTitle()
Android Developers: WebViewClient
Android Developers: WebView

My observation is that, you get the webpage title using WebChromeClient in lesser time than using WebViewClient
webview.setWebChromeClient(new WebChromeClient() {
#Override
public void onReceivedTitle(WebView view, String title) {
super.onReceivedTitle(view, title);
if (!TextUtils.isEmpty(title)) {
YourActivity.this.setTitle(title);
}
}
});

Simplest way to read title of page in Kotlin :
webView.webViewClient = object : WebViewClient() {
//....
override fun onPageFinished(view: WebView, url: String) {
val title = view.title
}
//...
}

So my experience you should use onReceivedTitle and onPageFinished both. I find that sometimes onPageFinished you won't get notify if you front end using react-router or something similar. And onReceivedTitle has flaw as #michael-levy mentioned.

private WebViewClient mWvClient = new WebViewClient() {
#Override
public void doUpdateVisitedHistory(WebView view, String url, boolean isReload) {
String title = view.getTitle();//getTitle
super.doUpdateVisitedHistory(view, url, isReload);
}
}

What if you do not want the whole title, and just a Domain Name, Like if you want to show only 'Google' from www.google.com, and you have all the query parameters in this title.
URL hostUrl= new URL(webView.getUrl());
String title = hostUrl.getHost();
title = title.startsWith("www.") ? title.substring(4) : title;

get image and title from webview
Image
img.setImageBitmap(webview1.getFavicon());
Title
txt.setText(webview1.getTitle());
