I have a problem with a specific site when loading in my apps internal webview.
In the LogCat i get these 2 lines (the tag is "chromium").
[INFO:CONSOLE(25)] "Uncaught TypeError: Cannot call method 'getItem' of null", source: http://m.ynet.co.il/Default_Ynet.aspx?type=3&id=4519238 (25)
[INFO:CONSOLE(73)] "Uncaught TypeError: Cannot call method 'push' of undefined", source: http://m.ynet.co.il/Default_Ynet.aspx?type=3&id=4519238 (73)
If i redirect to the external browser all is fine. Also it happens only with the above site (see in logcat)
public class WebActivity extends Activity {
WebView wv;
final Activity activity = this;
#SuppressLint("SetJavaScriptEnabled")
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
this.getWindow().requestFeature(Window.FEATURE_PROGRESS);
setProgressBarIndeterminateVisibility(true);
setContentView(R.layout.activity_web);
wv = (WebView)findViewById(R.id.webView1);
Intent intent = getIntent();
final String url = intent.getStringExtra("url");
Log.i("webView", url);
wv.getSettings().setJavaScriptEnabled(true);
wv.getSettings().setBuiltInZoomControls(true);
wv.getSettings().setLoadWithOverviewMode(true);
wv.getSettings().setUseWideViewPort(true);
wv.setWebChromeClient(new WebChromeClient() {
public void onProgressChanged(WebView view, int progress)
{
activity.setTitle("Loading...");
activity.setProgress(progress * 100);
if(progress == 100)
activity.setTitle(R.string.app_name);
}
});
wv.setWebViewClient(new WebViewClient() {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url)
{
view.loadUrl(url);
return true;
}
});
wv.loadUrl(url);
}
Any ideas?
It turns out that there was a problem using the shouldOverrideUrlLoading method (below) with this particular site.
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url)
{
view.loadUrl(url);
return true;
}
Once this was deleted all was good...

Hi there Need help i need Certain links to load external and not thru Webview
for example my link www.sample.com and sub links internal and www.google.com external.
mWebView.setWebViewClient(new MyWebViewClient() {
#Override
public void onReceivedSslError(final WebView view, final SslErrorHandler handler, final SslError error) {
handler.proceed();
}
});
swipeRefreshLayout.setOnRefreshListener(new SwipeRefreshLayout.OnRefreshListener() {
#Override
public void onRefresh() {
swipeRefreshLayout.setRefreshing(false);
}
});
Uri uri = getIntent().getData();
if(uri!=null)
{
String path = uri.toString();
Toast.makeText(MainActivity.this, "Path = "+path,Toast.LENGTH_LONG).show();
}
// REMOTE RESOURCE
mWebView.loadUrl(getString(R.string.web_url));
mWebView.setWebViewClient(new WebViewClient());
I have in my ViewSwitcher a ListView and a WebView. In my ListView's adapter, I have an onclick listener that writes the clicked url in the list to sharedpreferences. I'm trying to load that url into the WebView using an onSharedPreferencesChangedListener.
This is the code in my adapter:
convertView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
viewSwitcher.showNext();
Settings.writeSettings(context, "webviewUrl",
urls.get(position));
}
});
return convertView;
And in the preference listener:
#Override
public void onSharedPreferenceChanged(SharedPreferences pref, String key) {
if (key.equals("webviewUrl")) {
Log.d("TAG", pref.getString(key, null));
WebView wv = (WebView) findViewById(R.id.rss_webview);
wv.getSettings().setJavaScriptEnabled(true);
wv.setWebViewClient(new MyWebViewClient());
wv.loadUrl("about:blank");
wv.loadUrl(pref.getString(key, null));
}
}
This works great except it only works once. The preference listener code logs the correct urls, and the code executes each time I want it to, but wv.loadUrl() method seems to do nothing after the first successful call. Can anyone explain to me why this is happening and perhaps offer a solution? Thanks.
I solved the problem by implementing a static ViewHolder on the WebView whose reference I needed to keep longer than its views' lifecycle.
private static final class WebViewHolder {
WebView wv;
}
#Override
public void onSharedPreferenceChanged(SharedPreferences pref, String key) {
WebViewHolder holder = new WebViewHolder();
if (key.equals("webviewUrl")) {
if (wv == null) {
wv = new WebView(this);
holder.wv = (WebView) findViewById(R.id.rss_webview);
holder.wv.getSettings().setJavaScriptEnabled(true);
holder.wv.setWebViewClient(new MyWebViewClient());
wv.setTag(holder);
} else {
holder = (WebViewHolder) wv.getTag();
}
holder.wv.loadUrl("about:blank");
holder.wv.loadUrl(pref.getString(key, null));
}
}
I am using activities and places to develop my application. When I click on the link on the left, my page is loaded, and I put the values in the fields. After I put the values, I send a RPC to the server, and get response back. This is also shown. Now the problem is that even if I click on the link on the left, I am getting the result page again. I am not getting the input page.
Impl code
#UiHandler("entInvoiceCompare")
void onClickSubmit(ClickEvent e) {
GWT.log("Going to enterprise compare place");
//listener.goTo(new EnterpriseInvoiceCompareViewPlace());
NewEBRM.getClientFactory().getPlaceController().goTo(new EnterpriseInvoiceCompareViewPlace());
}
Place
public class EnterpriseInvoiceCompareViewPlace extends Place{
public EnterpriseInvoiceCompareViewPlace() {
GWT.log("EnterpriseInvoiceCompareViewPlace: constructor");
}
public static class Tokenizer implements PlaceTokenizer<EnterpriseInvoiceCompareViewPlace> {
#Override
public String getToken(EnterpriseInvoiceCompareViewPlace place {
GWT.log("EnterpriseInvoiceCompareViewPlace: getToken: call");
return "EntInvoiceCompare";
}
#Override
public EnterpriseInvoiceCompareViewPlace getPlace(String token) {
GWT.log("EnterpriseInvoiceCompareViewPlace: getPlace: call");
return new EnterpriseInvoiceCompareViewPlace();
}
}
}
Activity
#Override
public void start(AcceptsOneWidget containerWidget, EventBus eventBus) {
// TODO Auto-generated method stub
GWT.log("EnterpriseInvoiceCompareActivity: start: starting activity");
EnterpriseInvoiceCompareView entInvoiceCompareView = clientFactory.getEnterpriseInvoiceCompareView();
entInvoiceCompareView.setPresenter(this);
containerWidget.setWidget(entInvoiceCompareView.asWidget());
GWT.log("EnterpriseInvoiceCompareActivity: start: ending activity");
}
I have a question about an error I get in Eclipse.
Eclipse says "The nested type DisplayMessageActivity cannot hide an enclosing type"
This is my script:
package com.example.warzonegaming;
public class DisplayMessageActivity {
public class DisplayMessageActivity extends Activity {
#SuppressLint("NewApi")
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// Get the message from the intent
Intent intent = getIntent();
String message = intent.getStringExtra(MainActivity.EXTRA_MESSAGE);
// Create the text view
TextView textView = new TextView(this);
textView.setTextSize(40);
textView.setText(message);
// Set the text view as the activity layout
setContentView(textView);
// Make sure we're running on Honeycomb or higher to use ActionBar APIs
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB) {
// Show the Up button in the action bar.
getActionBar().setDisplayHomeAsUpEnabled(true);
}
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case android.R.id.home:
NavUtils.navigateUpFromSameTask(this);
return true;
}
return super.onOptionsItemSelected(item);
}
}
}
Does someone knows an fix for this, because I can't go further now.
Regards
Try learn basics of javapackage com.example.warzonegaming;
public class DisplayMessageActivity extends Activity {
#SuppressLint("NewApi")
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// Get the message from the intent

I simply want to create an apk that will take a url, and open a window and simply run like a browser
so far I have:
public class Browser extends Activity {
WebView mWebView;
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
mWebView = (WebView) findViewById(R.id.webview);
mWebView.getSettings().setJavaScriptEnabled(true);
mWebView.loadUrl("http://www.google.com");
}
}
This works fine, except when i open a link it'll take me to the actual browser, I'm having trouble where to place this code to override links opening in a new browser:
private class HelloWebViewClient extends WebViewClient {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return true;
}
}
WebView has a setWebViewClient method.
so you'd do something like
mWebView.setWebViewClient(new HelloWebViewClient());
Check out my project called FriarFramework, which is an ebook app publisher.
It basically takes a collection of HTML files locally and packages them up into a WebView.
https://github.com/hanchang/Friar-Framework
Try this
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) {
progressBar.setVisibility(View.GONE);
}
});
mWebView.setWebViewClient(new HelloWebViewClient());
This should be enough.
for more see the official doc about Building web apps in WebView
You have to implement WebViewClient.
You can detect URL inside shouldOverrideUrlLoading() method:
browser.setWebViewClient(new WebViewClient() {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
// You can have URL here
}
});
