In my app , I am having a webview . In webview ,I am showing HTML content which is having tag , .I have 2 tabs in that which should switch on clicking on same place. But in webview they are coming one after the other.
In HTML file, I am calling method of Jquery file that method is not getting called . In browser its working fine. In iOS its working.
I am loading webview with base Url method only.
webView.loadDataWithBaseURL(pathToHtml, strLoad, "text/html","UTF-8", "");
These files are in assets . I am not sure that I am able to provide correct path for jquery files. So , I copied files to sdcard. There I am giving path. So path can not be the issue.
Please help me out . I tried many things but nothing worked. I am not getting what is the issue.
You can call a javascript function from webView.loadUrl("javascript:testFunction();"); to change the tabs insted of loading the page again. at the first load, you can use webView.loadUrl("file:///android_asset/index.html"); Befor using the jquery code, make sure that javascript enabled, set the webviewclient and webchromeclient for the webView.

When I try to reload the titanium webview true webview.reload(), the view does not reload correctly. Instead if loading the page it gives me a page not found.
what i'm doing:
In Titanium i make use of webviews to display data. These webviews make use of HTML that is stored in the local filesystem that Titanium offers. The webview is called url is set by :
webview.setUrl( Ti.Filesystem.applicationDataDirectory.toString() + 'index.html');
This sets the proper url for the webview, it let's me see the correct html page. When I use webview.reload(), it seems lost... is there a way to reload the webview, or should i remove and then add the webview again?
Setting a URL for WebView the resource is usually loaded from the Resources folder.
So try to move all HTML files there (into Resources, same folder where app.js is located) and simply use.
webview.setUrl('index.html');
This has worked for me both on iOS and Android.
(There is an issue related to Android regarding WebView and setting its content by html property but this shouldn't matter here)
In my app, am loading a local html which is residing in SD card as
String extPath = getExternalFilesDir(null).toString();
String html = getHtml(extPath+File.separator+fileName); //it just reads html file and returns content as string
webvu.loadDataWithBaseURL("file://"+extPath+File.separator,html ,
"text/html","UTF-8", null);
the html file loaded in the web view (webvu) tries to load another html file with $.load ajax call
$.load("base.html",function(){ ... });
ajax load is throwing the below error. How can I resolve this
XMLHttpRequest cannot load
file:///storage/emulated/0/Android/data/com.example.sdcardwebview/files/sec.html.
Cannot make any requests from null. at null:1
I finally figured out the solution
The null origin issue happens only in JB, which supposedly has a webview based on new webkit which implements stricter same origin policy.
Hence the code in question works perfectly fine on all version of android below JB. To get the code work on JB, all we need to do is change web view settings. Just call
webView.getSettings().setAllowUniversalAccessFromFileURLs(true);
I want to use two html in a single webpage so i choose to implement frameset in html. it works fine in all android version except android4.0. If i html file in default browser its working fine but in webview only one frame is loaded not the other ie first frame is override by second frame so it looks only second frame is loading.
here is my code for loading html in webview..
WebView web=new WebView(this);
String url="<html><frameset cols=\"25%,25%\" FRAMEBORDER=NO FRAMESPACING=0 BORDER=0><frame src=\"file:///android_asset/preview.html"
+"\" /><frame src=\"file:///android_asset/preview.html\" /> </frameset></html>";
web.loadDataWithBaseURL("file:/"+baseurl+"/",url, "text/html", "utf-8","");
i dont know why its not supporting in android4.0 whether android webview is not accepting frame in 4.0 or not? If anyone knows please help me..
In my little app i have a webview, i only have one html file in the assets folder. I'm trying to use a named anchor to make a Jump Link but it doesn't work. It only says Web page not available I don't know where i'm wrong. Is it trying to load a html file with the name tag i provided?
WebView mWebView = (WebView) findViewById(R.id.mywebview);
mWebView.loadUrl("file:///android_asset/topics.html");
EDIT:
here's my html
<html>
<body>
<a href=”#tip”>Go somewhere</a>
//a lot of <br/>...
Somewhere
<a name=”tip”></a>
</body>
</html>
And yes the topics.html is under assets/
Where does your program fail - with the loading or when you click the anchor? It sounds like the problem is with your HTML file, so you should probably show the code from that instead. :) Also, the full LogCat output is handy too. The more info the merrier.
I recently implemented a WebView, the HTML code is extremely straight-forward (since I know close to no HTML and just wanted an easy way to display documentation). A simple anchor is just this for example:
Navigating the application
...
<a name="q1"></a>
<p><b>Navigating the application</b></p>
<p>...sliding motion (to the left or to the right) with your finger...</p>
If your program is failing at the actual loading part, then ensure that you have placed the topics.html file correctly in the /assets/ folder in your project folder. It has to be at the very root of your project folder - ie. workspace\<projectname>\assets\topics.html
Your code for loading the webpage looks fine.
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.
