How can i block or avoid popup in webview?

the webpage have some popup ads is there any way to prevent the popup from loading when the popup loads the main site doesnt appears is there any way to load the main page with out popups and how can i add a download handler l mean the webview should support downloading .torrent file
public class MainActivity extends AppCompatActivity {
private WebView webView;
private ProgressBar progressBar;
private LinearLayout layoutProgress;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
webView = (WebView) findViewById(R.id.webView);
progressBar = (ProgressBar) findViewById(R.id.progressBar);
layoutProgress = (LinearLayout) findViewById(R.id.layoutProgress);
webView.setVisibility(View.GONE);
WebSettings settings = webView.getSettings();
settings.setJavaScriptEnabled(true);
settings.setBuiltInZoomControls(true);
settings.setSupportZoom(true);
settings.setDisplayZoomControls(false);
webView.setWebViewClient(new WebViewClient() {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return true;
}
#Override
public void onPageFinished(WebView view, String url) {
webView.setVisibility(View.VISIBLE);
layoutProgress.setVisibility(View.GONE);
progressBar.setIndeterminate(false);
super.onPageFinished(view, url);
}
public void but(View v){
}
#Override
public void onPageStarted(WebView view, String url, Bitmap favicon) {
layoutProgress.setVisibility(View.VISIBLE);
progressBar.setIndeterminate(true);
super.onPageStarted(view, url, favicon);
}
});
if(isOnline()) {
webView.loadUrl("http://testsite.com/");
} else {
String summary = "<html><body><font color='red'>No Internet Connection</font></body></html>";
webView.loadData(summary, "text/html", null);
toast("No Internet Connection.");
}
}
private void toast(String message) {
Toast.makeText(this, message, Toast.LENGTH_LONG).show();
}
public void onBackPressed() {
if(webView.canGoBack()) {
webView.goBack();
} else {
super.onBackPressed();
}
}
private boolean isOnline() {
ConnectivityManager cm = (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE);
NetworkInfo netInfo = cm.getActiveNetworkInfo();
return (netInfo != null && netInfo.isConnected());
}
public void but(View v){
webView.loadUrl("http://testsite.com/");
}
}

if the url changes then use shouldOverrideUrlLoading with some regex
so
List<String> validUrls = new LinkedList<>();
validUrls.add("https://www\\.google\\.com/*");
validUrls.add("https://www\\.facebook\\.com/*");
#Override public boolean shouldOverrideUrlLoading(WebView view, String url) {
if (isValidUrl(url)) {
return false;
}
return true;
}
private boolean isValidUrl(String url) {
for (String validUrl : validUrls) {
Pattern pattern = Pattern.compile(validUrl, Pattern.MULTILINE);
Matcher matcher = pattern.matcher(url);
if (matcher.find()) {
return true;
}
}
return false;
}
would match against any www.google.com or facebook.com urls

You can intercept the urls that are opened from the webview, I don't know if it would work with the popup:
WebViewClient client= new WebViewClient(){
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url){
if (url.equals("popupURL"){
return true;
}
return false;
}
}
webView.setWebViewClient(client);

Can't load url with android WebView

I am loading some urls in my app using android WebView and all successful. But when i am trying to load this url:
http://dev.infibond.com/cloud/instagram?user_profile=https%3A%2F%2Fscontent.cdninstagram.com%2Ft51.2885-19%2Fs150x150%2F13534190_829691380497090_1099495058_a.jpg&user_name=infibondtest
But for some reason i am failing - "view.loadUrl(url);" in "shouldOverrideUrlLoading" doesn't show the page and doesn't load another url. just shows a white page.
The response code from the server is 304.
Before i am getting to this url, i am doing authentication with Instagram and sending the access token as a cookie.

I am not 100% sure, but it seems like you have a lot of small errors. I think the one in question is here:
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
handleProgressBarVisibility(url);
String cookieString = WEB_VIEW_TOKEN + "=" +
NetworkManager.instance().getToken();
CookieManager.getInstance().setCookie(mUrl, cookieString);
view.loadUrl(url);
return true;
}
The view.loadUrl(url) seems very wrong to me. I think you may need to change this to something like:
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
if (Uri.parse(url).getHost().equals("dev.infibond.com")) {
return false;
}
// otherwise, they are leaving the site, so open a new
// browser instead
Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(url));
view.getContext().startActivity(intent);
return true;
}
And remove the guts of what you did here. Most of it is findViews() and should not be repeated anyway. I'm guessing this is what you meant to do with
handleProgressBarVisibility(url) in the WebViewClient but I'm not really sure:
#Override
public void onLoadResource(WebView view, String url) {
handleProgressBarVisibility(url);
}

How to load the data in webview page by page in android

I am using webview to display the html data.It is working fine if the data is less(less than 1 mb)..I am using following code
mDecryptDataWv.setWebViewClient(new WebViewClient() {
public boolean shouldOverrideUrlLoading(WebView view, String url) {
DebugLog.i(TAG, "Processing webview url click...");
view.loadUrl(url);
return true;
}
#Override
public void onPageStarted(WebView view, String url, Bitmap favicon) {
// TODO Auto-generated method stub
//showProgressDialog();
DebugLog.i(TAG, "************onPageStarted **************");
}
#Override
public void onPageFinished(WebView view, String url) {
DebugLog.i(TAG, "************onPageFinished **************");
if (mProgressDialog != null) {
if (mProgressDialog.isShowing()) {
DebugLog.i(TAG, "mProgressDialog ::::::stopping");
mProgressDialog.dismiss();
mProgressDialog = null;
}
}
If the data is more then 1MB it is taking more time to complete the loading.so my intention is to load the data page by page upon user scrolling with progress dialog..Can anyone has idea?

WebView not working

i want to disable phone browser and i want to use a webview .
but this code didn't work for me . please guide me :
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Wop=(WebView)findViewById(R.id.webi);
String mturl="http://www.google.com";
Wop.getSettings().setJavaScriptEnabled(true);
Wop.loadUrl(mturl);
}

mWebView = (WebView) findViewById(R.id.webview);
mWebView.getSettings().setJavaScriptEnabled(true);
mWebView.setWebViewClient(new HelloWebViewClient());
mWebView.loadUrl("http://www.stackoverflow.com");
To enable the previous web-page to be loaded,
public boolean onKeyDown(int keyCode, KeyEvent event) {
if ((keyCode == KeyEvent.KEYCODE_BACK) && mWebView.canGoBack()) {
mWebView.goBack();
return true;
} }
Definiton of the HelloWebViewClient class :
private class HelloWebViewClient extends WebViewClient {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return true;
}
#Override
public void onPageFinished(WebView view, String url) {
// TODO Auto-generated method stub
super.onPageFinished(view, url);
//what you want to do when the page finished loading, eg. give some message, show progress bar, etc
}
#Override
public void onPageStarted(WebView view, String url, Bitmap favicon) {
// TODO Auto-generated method stub
super.onPageStarted(view, url, favicon);
//what you want to do when the page starts loading, eg. give some message
}
}

WebView w = new WebView(this);
//add this to your code
w.setWebViewClient(new Callback());
w.loadUrl("http://www.facebook.com");
//and this class also
private class Callback extends WebViewClient{ //HERE IS THE MAIN CHANGE.
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
return (false);
}
}

Progress Dialog In Webview

Simply put how can I make a progress dialog show up every time a new link is clicked in my webview. I have tried many tutorials and methods but every one of them only shows the dialog once, when the app is initially loaded.
Here is my code
mWebView.setWebViewClient(new WebViewClient() {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url)
{
view.loadUrl(url);
return true;
}
ProgressDialog dialog = ProgressDialog.show(myActivity.this, "",
"Loading. Please wait...", true);
#Override
public void onPageFinished(WebView view, String url) {
dialog.dismiss();
}

check out this:
wvCouponsAndOffers.setWebViewClient(new WebViewClient() {
ProgressDialog progressDialog = new ProgressDialog(CouponsWebViewUI.this);
#Override
public void onPageStarted(WebView view, String url, Bitmap favicon) {
super.onPageStarted(view, url, favicon);
progressDialog.setMessage(StringConstants.PROGRESS_DIALOG_MSG);
progressDialog.setCancelable(false);
progressDialog.setOnKeyListener(new OnKeyListener(){
#Override
public boolean onKey(DialogInterface dialog, int keyCode,
KeyEvent event) {
if(keyCode == KeyEvent.KEYCODE_SEARCH) {
return true;
}
else
return false;
}});
progressDialog.show();
}
public boolean shouldOverrideUrlLoading(WebView view, String url) {
progressDialog.setMessage(StringConstants.PROGRESS_DIALOG_MSG);
progressDialog.setCancelable(false);
progressDialog.setOnKeyListener(new OnKeyListener(){
#Override
public boolean onKey(DialogInterface dialog, int keyCode,
KeyEvent event) {
if(keyCode == KeyEvent.KEYCODE_SEARCH) {
return true;
}
else
return false;
}});
progressDialog.show();
view.loadUrl(url);
return true;
}
public void onPageFinished(WebView view, String url) {
if (progressDialog.isShowing()) {
progressDialog.dismiss();
}
}
});

Try this,
// Let's display the progress in the activity title bar, like the
// browser app does.
getWindow().requestFeature(Window.FEATURE_PROGRESS);
webview.getSettings().setJavaScriptEnabled(true);
final Activity activity = this;
webview.setWebChromeClient(new WebChromeClient() {
public void onProgressChanged(WebView view, int progress) {
// Activities and WebViews measure progress with different scales.
// The progress meter will automatically disappear when we reach 100%
activity.setProgress(progress * 1000);
}
});
webview.setWebViewClient(new WebViewClient() {
public void onReceivedError(WebView view, int errorCode, String description, String failingUrl) {
Toast.makeText(activity, "Oh no! " + description, Toast.LENGTH_SHORT).show();
}
});
webview.loadUrl("http://slashdot.org/");
And if you want to make your own progressDialog then
webView.setWebViewClient(new WebViewClient() {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url)
{
// Start PROGRESS DIALOG
view.loadUrl(url);
return true;
}
#Override
public void onPageFinished(WebView view, String url) {
//HIDE PROGRESS DIALOG LOADING IT HAS FINISHED
}
});
And let me know what happen..

Try this easiest one,it work for me
public class HomeWebViewActivity extends AppCompatActivity{
private String weburl;
private WebView webview;
private Toolbar toolbar;
private ProgressDialog prDialog;
#Override
protected void onCreate(#Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.home_webview_activity);
toolbar = (Toolbar) findViewById(R.id.toolbar_homewebview);
setSupportActionBar(toolbar);
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
getSupportActionBar().setDisplayShowHomeEnabled(true);
weburl="ADD YOUR URL HERE";
webview = (WebView) findViewById(R.id.webviewinfo);
webview.setWebViewClient(new WebVwClientcls());
webview.getSettings().setJavaScriptEnabled(true);
webview.getSettings().setCacheMode(WebSettings.LOAD_CACHE_ELSE_NETWORK);
webview.loadUrl(weburl);
}
private class WebVwClientcls extends WebViewClient {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return true;
}
#Override
public void onPageStarted(WebView view, String url, Bitmap favicon) {
super.onPageStarted(view, url, favicon);
prDialog = new ProgressDialog(HomeWebViewActivity.this);
prDialog.setMessage("Please wait ...");
prDialog.show();
}
#Override
public void onPageFinished(WebView view, String url) {
super.onPageFinished(view, url);
if(prDialog!=null){
prDialog.dismiss();
}
}
}
}
