You have to decode HTML:
URL yahoo = new URL("http://www.yahoo.com/");
BufferedReader in = new BufferedReader(
new InputStreamReader(
yahoo.openStream()));
String inputLine;
while ((inputLine = in.readLine()) != null)
System.out.println(inputLine);
in.close();
After that get Image Tag from it then you can get mages from it and write to sd card.

Android loginvia facebook in pinterest is not working in webview

Android - Am loading a following url in webview "https://www.pinterest.com", it loads successfully, but when i click on login via facebook or login via google in pinterest it's loading a blank screen rather than loading the actual result, below is my code, please help me. The same code is working for other urls, but not for Pinterest alone.
public class Pinterest extends Fragment {
private WebView wv1;
String url="https://www.pinterest.com";
private ProgressBar progress;
View mView;
WebSettings settings;
ImageView back,top;
public Pinterest() {
// Required empty public constructor
}
#Override
public void onCreate(#Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setHasOptionsMenu(true);
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
mView= inflater.inflate(R.layout.pinterest, container, false);
wv1 = mView.findViewById(R.id.pin_webView);
progress = mView.findViewById(R.id.pin_progressBar);
back= mView.findViewById(R.id.go_back);
top= mView.findViewById(R.id.goToTop);
progress.setMax(100);
settings = wv1.getSettings();
settings.setJavaScriptEnabled(true);
settings.setAllowContentAccess(true);
settings.setDomStorageEnabled(true);
wv1.setWebViewClient(new myWebClient());
wv1.setVerticalScrollBarEnabled(true);
wv1.setHorizontalScrollBarEnabled(true);
wv1.loadUrl(url);
progress.setProgress(0);
wv1.setWebChromeClient(new WebChromeClient() {
#Override

if (newProgress == 100) {
progress.setVisibility(View.GONE);
}
super.onProgressChanged(view, newProgress);
}
});
back.setOnClickListener(v -> {
if(wv1.canGoBack())wv1.goBack();
});
top.setOnClickListener(v -> {
Constants.goTop(wv1);
});
return mView;
}
public void setValue(int progress) {
this.progress.setProgress(progress);
}
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
System.out.println("when you click on any interlink on webview that
time you got url :-" + url);
// view.loadUrl(url);
return false;
}
#Override
public void onPageFinished(WebView view, String url) {
System.out.println("your current url when webpage loading.. finish"
+ url);
super.onPageFinished(view, url);
}
}
}

It looks like requests from WebView are working only when the Facebook app is installed on the device.
See Practice #5 in the Facebook docs.
https://developers.facebook.com/docs/facebook-login/best-practices?locale=en_US
Google has been blocking since April 2017 all the requests related OAuth2, which are using WebView (due to security concerns).

Android webview setWebViewClient() show nothing

guys! I have problem to load html page with android-webview. I need to load the url with my webview but not with the mobile system broswer or other broswer, so I have to apply the method setWebViewClient() to my webview but not WebChromeClient(). However, there's load nothing but blank page when applied the setWebViewClient(), and works fine with the later method. I don't know where's problem, here is the code:
.xml :
<WebView android:id="#+id/webview"
android:layout_marginTop="50dp"
android:layout_width="fill_parent"
android:layout_height="fill_parent"/>
.java :
WebView webView = (WebView)findViewById(R.id.webView);
WebSettings webSettings = webView.getSettings();
webSettings.setJavaScriptEnabled(true);
if (Build.VERSION.SDK_INT >= 19) {
webSettings.setCacheMode(WebSettings.LOAD_CACHE_ELSE_NETWORK);
}
private String loadUrl = "http://www.baidu.com";
webView.loadUrl(loadUrl);
webView.setWebViewClient(new WebViewClient() {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return true;
}
#Override
public void onLoadResource(WebView view, String url) {
view.loadUrl(url);
super.onLoadResource(view, url);
}
#Override
public void onPageStarted(WebView view, String url, Bitmap favicon) {
view.loadUrl(url);
super.onPageStarted(view, url, favicon);
}
});
/*
webView.setWebChromeClient(new WebChromeClient() {
#Override
public void onProgressChanged(WebView view, int newProgress) {
Log.v(Log_Tag, String.valueOf(newProgress));
}
});
*/

Just put this code in your activity
private String loadUrl = "https://www.google.com";
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
WebView mWebView = (WebView) findViewById(R.id.webView);
WebSettings mWebSettings = mWebView.getSettings();
mWebSettings.setJavaScriptEnabled(true);
WebViewClient mWebViewClient = new WebViewClient();
mWebView.setWebViewClient(mWebViewClient);
mWebView.loadUrl(loadUrl);
}
You shouldn't override methods in WebViewClient class if you don't want to change their behavior or add some functionality. And don't forget to add permission Internet to your manifest file. WebView will not work without it.

Thanks #Mike M. again. The method shouldOverrideUrlLoading() should return false if you want to loading the url with your webView but not with the mobile system default browser or other Third-Party browsers. And, if you want to deal some javascript actions of the webpage with your webView, you're suggested to apply the WebChromClient to your webView.
Here is the good example:
WebView webView = (WebView)findViewById(R.id.webView);
WebSettings webSettings = webView.getSettings();
webSettings.setJavaScriptEnabled(true);
//load the page with cache
if (Build.VERSION.SDK_INT >= 19) {
webSettings.setCacheMode(WebSettings.LOAD_CACHE_ELSE_NETWORK);
}
webView.setWebViewClient(new WebViewClient() {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
//return true load with system-default-browser or other browsers, false with your webView
return false;
}
#Override
public void onLoadResource(WebView view, String url) {
super.onLoadResource(view, url);
}
#Override
public void onPageStarted(WebView view, String url, Bitmap favicon) {
super.onPageStarted(view, url, favicon);
}
});
webView.setWebChromeClient(new WebChromeClient() {
#Override
public void onProgressChanged(WebView view, int newProgress) {
Log.v(Log_Tag, String.valueOf(newProgress));
//put your code here if your want to show the progress with progressbar
}
});
private String loadUrl = "http://www.baidu.com";
webView.loadUrl(loadUrl);

public class MainActivity extends AppCompatActivity {
WebView webView;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
webView = findViewById(R.id.webView);
webView.setWebViewClient(new WebViewClient());
webView.getSettings().setJavaScriptEnabled(true);
webView.loadUrl("https://www.w3schools.com/");

Preventing WebView from closing when clicked outside the webview

In my app, I load a WebView where users enter username/password and I don't want the webview to close should the users accidentally click outside of the webview since the page will have to make another network call to load this webview.
I know this can be done for Dialog (like so: dialog.setCanceledOnTouchOutside(true);) but couldn't find similar mechanism for webview.
Thanks!
Here is the code:
#SuppressLint("SetJavaScriptEnabled")
public class LoginDialogFragment extends DialogFragment {
private static final String TAG = LoginDialogFragment.class.getSimpleName();
View mainView = null;
WebView webView = null;
OnLoginSucceeded loginSucceeded = null;
ProgressBar progressBar = null;
#Override
public void onSaveInstanceState(Bundle outState) {
super.onSaveInstanceState(outState);
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
mainView = inflater.inflate(R.layout.webview, container, false);
if (getDialog() != null)
getDialog().setTitle(getString(R.string.login));
webView = (WebView) mainView.findViewById(R.id.webview);
//display the progress bar
progressBar = (ProgressBar) mainView.findViewById(R.id.user_profile_loading_progress);
progressBar.setVisibility(View.VISIBLE);
//turn caching off
webView.getSettings().setCacheMode(WebSettings.LOAD_NO_CACHE);
webView.getSettings().setJavaScriptEnabled(true);
webView.getSettings().setPluginsEnabled(true);
webView.setWebChromeClient(new WebChromeClient() {
});
webView.setWebViewClient(new WebViewClient() {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return true;
}
#Override
public void onPageStarted(WebView view, String url, Bitmap favicon) {
Log.i(TAG, "URL received in onCreateView's onPageStarted is: " + url);
new HandleRequest().execute(url);
}
#Override
public void onPageFinished(WebView view, String url) {
}
});
new FetchLoginFormTask().execute();
return mainView;
}

I found my answer here and I just used getDialog().setCanceledOnTouchOutside(false); ensuring that when back key is clicked, the webview is dismissed.

Try with override the method:
#Override
public void setCancelable(boolean cancelable) {
super.setCancelable(false);
}
If your issue is not getting solved by this then please put some code so i can help you.
Feel free for comment.

How to use ProgressDialog with webview in a fragment

Now im trying to show a page in webview, it takes some time to load, meanwhile i want to show a progressDialog. The best i could do was the code below, but the problem is that im doing it in onCreateView, so the progressDiealog only shows until the view is created, which is not what i want. I know that i have to use it in onActivityCreated , but im not sure how to do that , thanks all in advance
public class someFragment extends SherlockFragment {
Context context;
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup group, Bundle saved)
{
View v = inflater.inflate(R.layout.some_layout, group, false);
final ProgressDialog pd = ProgressDialog.show(getActivity(), "", "Loading", true);
final WebView myWebView = (WebView) v.findViewById(R.id.webViewsome);
myWebView.setWebViewClient(new WebViewClient() {
#Override
public void onPageFinished(WebView view, String url) {
pd.dismiss();
}
});
myWebView.getSettings().setPluginsEnabled(true);
myWebView.getSettings().setBuiltInZoomControls(false);
myWebView.getSettings().setSupportZoom(false);
myWebView.getSettings().setJavaScriptCanOpenWindowsAutomatically(true);
myWebView.getSettings().setJavaScriptEnabled(true);
myWebView.getSettings().setAllowFileAccess(true);
myWebView.getSettings().setDomStorageEnabled(true);
myWebView.setInitialScale(25);
myWebView.getSettings().setDefaultZoom(ZoomDensity.FAR);
myWebView.loadUrl("http://www.test.com/test-0.jpg");
return v;
}
}

Try this in SomeFragment:
private class MyWebViewClient extends WebViewClient {
#Override
public void onPageFinished(WebView view, String url) {
//remove your progressdialog here
super.onPageFinished(view, url);
}
#Override
public void onPageStarted(WebView view, String url, Bitmap favicon) {
//show your progressdialog here
super.onPageStarted(view, url, favicon);
}
}
then:
webView.setWebViewClient(new MyWebViewClient());

One thing you can do is, in onCreateView start a AsyncTask with a progressDialog in it. In onPageFinished(after web page completely loaded) of webView, cancel that task. Hope its useful.
