I have a Google Map opening in a Webview using query strings and the API to determine the location.
This worked fine up until a week or so ago; now the window pops up asking what application you would like to use.
Has something changed? How can I stop this box popping up and have the webview handle the map instead of it trying to open a new browser or Maps?
Relevant code:
String detail = (String)getIntent().getExtras().get(CustomizedListView.KEY_DETAIL);
WebView detailweb = (WebView)findViewById(R.id.detailsText);
detailweb.loadData(detail, "text/html", "UTF-8");

I'm working on an app with a custom url scheme.
It is opening some webpage for authentication in a chrome tab. This is done in xamarin forms like this:
Browser.OpenAsync(apiUrl + "mobile", new BrowserLaunchOptions
{
LaunchMode = BrowserLaunchMode.SystemPreferred,
TitleMode = BrowserTitleMode.Hide,
});
everything work as expected if I return a webpage with a link and click the the link manually:
Click here to go the app
But if i return a 302 redirect to the same url it will not close the chrome tab and dont focus the app again.
If i add a javascript in the response, it will not automatically open the url (close the chrome tab and focus the app)
I've tried things like this:
window.location = url;
window.open(url,'_self');
setTimeout(()=>window.open(url,'_self'),10);
(url is a valid variable, even tried alert(url) after changing the location and it show the correct url.
Why does it only work when I click the link manually?
In order to maintain the user's security and experience, the browser prohibits the direct use of window.open(URL) in JS to open new links.
Try to change like below:
setTimeout(()=>window.open(url,'_self'),500); //The delay time must not be too short or you will be intercepted

You can create an instance of a WebView and load the URL of the Google Maps site. You can add parameters to the URL which allows you to use more functionality than is available using the Java-based Google Maps API.
Below code snippet shows how to create instance of a WebView to display a mobile Google Maps URL with parameters in an Android App. The main activity of your app should contain the following lines in its onCreate() method.
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
WebView webView = (WebView) findViewById(R.id.mywebview);
webView.getSettings().setJavaScriptEnabled(true);
webView.loadUrl("http://maps.googleapis.com/maps/api/staticmap?
ll=36.97,%20-122&lci=bike&z=13&t=p&size=500x500&sensor=true");
}
I have the URL of a webpage to be displayed into a webview in my Android app. Before showing this page i want to clear the html code of this page from some tag (such as the header, footer, ecc..) in order to show only few information. How can i do it? I tried to solve the issue working with JSoup but i can't understand how to create and pass the "new page" to the webview. Anybody can help me?
EDIT
I cleaned the html code useless through jsoup libraries. Then, always by mean of these, i get head and body content and finally i showing the "cleared" web page through these lines:
headURL = doc.select("head").outerHtml();
bodyURL = doc.select("body").outerHtml();
webview.loadData( "<html>"+headURL+bodyURL+"</html>" , "text/html", "charset=UTF-8");
webview.setWebViewClient(new DisPlayWebPageActivityClient());
The view shows the new page but do not load css files specified in the head(that has not been touched). Who can say me why?
You can fetch the WebPage you want to display as a string, parse and remove whatever you don't want and then load this string as data in your webview.
Something like:
String webContent = fetchPage(url);
String cleanedWebContent = cleanUp(webContent);
webView.loadData(cleanedWebContent, "text/html", "UTF-8");
Of course, you will need to implement fetchPage and cleanUp as they are not Android methods
I implemented the the Android webview encounter some problem
Beginning do a OptionMenu, and he will appear when you press the Menu four locations
I use the mouse click taipei he displayed to Toast
But I would like to implement the functionality Toast message screen webview display the specified web page
I use Intent a = new Intent (Intent.ACTION_VIEW, Uri.parse ();
startActivity (a);
Can successfully display the webpage
But I would like to the webview implement web pages using setContentView ();
Switch to taipei.xml <= webview, when I click on the submit button, it could not display the webpage using webview
Please help me to see where the problems lie, because beginners just learning, I hope to try to attach the code to solve my problem.

I take the response from an HTTP connection in the form of string and show that to webview like this:
WebView engine = (WebView)findViewById(R.id.webview);
engine.loadData(endResult, "text/html", "UTF-8"); /*endresult is string*/
I actually get a response that contains the google page (google search result direct from google.com).
The loadData method works well i.e it shows the web page but when I click on one of the links on that page it shows "page not available" and said that "xyz link might be temporarily down or it may have moved to permanently to a new web address".
this happens for all links accept the first present link on that page. i.e it shows correct page from first link on that page but fails for others..
I noticed that OSes prior to 2.3 failed to follow links if setHorizontalScrollBarEnabled and setVerticalScrollBarEnabled are set to false.
try to use loadDataWithBaseURL of the WebView class
I would avoid using engine.loadData - it seems to cause all sorts of crazy problems.
Use engine.loadDataWithBaseURL instead, and pass the base URL of where the content exists. I would think that the content you are loading is using relative paths in it's HTML so it's looking inside your app resources. By specifying the base URL you get around this problem.
