I have problems loading my local html in to webView in my Application heres the code -
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_weekly);
WebView ww = (WebView) findViewById(R.id.webViewer5);
ww.addJavascriptInterface(new myJsInterface(this), "Android");
ww.loadUrl("file:///assets/pro/index.html");
The Result from the App says:
Webpage Not available
the Web page at file:///assets/pro/index.html might be temporarily down or it may have moved permanently to a new web address.
The HTML file works fine alone or in a browser just not in the webViewer.
assets folder should be accessed using file:///android_asset. change to below:
ww.loadUrl(" "file:///android_asset/pro/index.html"); or ww.loadUrl(" "file:///android_asset/index.html"); (since i cant see your directory structure)

TLDR; In a Javascript file for my Firefox extension, how can I load the contents of other files from inside my extension (such as an HTML view & CSS stylesheet) for use on the current web-page?
I'm working on my first Firefox extension, for personal use.
So I setup my manifest.json to load /script/panel.js when any page of the site loads.
In panel.js, I would like to do something like:
const html = MyExtension.getFileContent('/view/panel.html');
const node = document.createElement('div');
node.innerText = html;
document.body.appendChild(node);
But I can't find anything like MyExtension.getFileContent(). All I've been able to find is how to add sidebar (through manifest?) & browser action for the toolbar at the top of the browser & other non-programmatic ways of exposing files that are inside my extension.
Then in /view/panel.html, Ideally, I'd like to also reference /style/panel.css which is also found inside my extension's root directory, such as with a <link tag.
Did you set web_accessible_resources in your manifest.json? It is required to make resources in your extension readable from webpages.

Currently I have a basic WebView set up with JavaFX and a html file that I need to load in my local home folder. However, when I set a URL object to the home folder and try to load that URL using the WebEngine's load function, the page does not load. The page content.html is perfectly fine. Here is my code:
String contentURL = new URL("file://" + System.getProperty("user.home") + "/content.html").toExternalForm();
webEngine.load(contentURL);
System.out.println(contentURL);
Put an extra slash to file protocol; "file:///". For more info follow this wiki.
I am developing an app which uses both Phonegap and JQuery Mobile.
The app connects to an external server to check for new content/content updates (html and pdf files).
If needed, in iOS those files are successfully downloaded into the app /Documents folder.
The app then retrieves each content file's absolute path (file://localhost/var/mobile/Applications/APPID/Documents/subfolder) and creates listviews that link to each file's absolute path.
The problem I am having is the following: tapping a listview opens the linked page BUT not as an ajax call. The page loads but then no javascript (cordova.js, jquery.js app.js etc) is referenced in the page and hence I can't navigate back to the main menu. It seems like the jQueryMobile ajax navigation stops working when I open html files in the /Documents folder.
This happens only for the downloaded content in the /Documents folder (and hence outside Phonegap's www folder).
From the remote debugger, if I try to call the $.mobile.changePage('previousPage.html')* function, the console returns that $ is not defined, as if the page couldn't reference jQuery. But in none of the pages in the /www folder I need to re-reference the js files.
The app uses a multipage layout and each page has its own javascript after the <div data-role="page" id="pageid"> container.
Each .html in the /Documents folder is structured as a jQueryMobile page (with data-role attributes).
This is the code that creates the listviews:
<script type="text/javascript">
$('#content').live('pagebeforeshow', function(e) {
var curCat = parseInt(window.localStorage.getItem('currentCat'));
console.log('PAGE BEFORE SHOW: CONTENT');
db.db.transaction(function(tx) {
tx.executeSql('SELECT * FROM `content` WHERE `content`.`catID` = ?', [curCat],
function(tx, result) {
var path = window.localStorage.getItem('contentPath') + '/';
if (result.rows && result.rows.length) {
var html = '<ul data-role="listview" id="linkUl">';
for (var i = 0; i < result.rows.length; i++) {
var filename = result.rows.item(i).index_file.substr(result.rows.item(i).index_file.lastIndexOf('/'));
console.log(result.rows.item(i).id);
html += '<li id="' + result.rows.item(i).id + '">';
html += '<a href="' + path + filename +'">';
html += result.rows.item(i).title;
html += '</a></li>';
}
html += '</ul>';
console.log(html);
$('#contCnt').html(html);
$('ul#linkUl').listview();
}
},
function(tx, error) {
console.log(error.code);
var html = '<div id="errorDB">';
html += 'ERROR RETRIEVING FILES';
html += '</div>';
$('#contCnt').html(html);
}
);
});
});
$('div#content').live('pageshow', function(e) {
$('ul#linkUl').listview('refresh');
});
</script>
where the ContentPath variable is stored as a fileSystem object's directory.toUrl();
My fear is that jQueryMobile can't ajax-pull html from an external directory (the /Documents folder in iOS), or that I am missing some attribute or setting in order to do so.
Perhaps because I am using an absolute url? If so, how can I get the relative url from Phonegap's /www folder?
Do I have to declare something on the cordova.plist file?
Also, the downloaded content won't have to contain any js, they should be only plain html, but I need to keep jQuery Mobile header/footer and navigation system in all the pages.
I am using Cordova 2.2.0 and the latest releases of both jQuery and jQuery mobile.
Thanks in advance and sorry if something in the formatting goes wrong, I am new to SO (in case I'll edit asap).
You can open files from the documents folder (or any other folder the app has read access to).
There are two reasons that a link may not load as an ajax page
jQuery Mobile thinks that it isn't part of the app
There is a javascript error loading the page, which causes the default link click action to run instead of the ajax loader.
You could try using a call to $.mobile.changePage instead of just setting up the links - that gives you a little bit more visibility into what is going on.
I don't think a file url in a different folder should be treated as a different domain by jQuery Mobile, but to eliminate that possibility it should be reasonably easy to construct a relative url to the documents folder.
Solved, and thanks to Tom who led me through the right direction.
I guess the problem was that jQueryMobile was interpreting the absolute path as a an external link and thus the WebView was opening the html files as a new file, detaching it from the rest of the application.
What I did was substituting the absolute path file://localhost/var/mobile/Applications/APPID/Documents/subfolder
with a relative one, which in my case is './../../Documents/subfolder/filename.html
and now it works like a charm.
Currently, I have an issue with populating an iframe that I have with a PDF document, but this issue only occurs in IE.
Basic Layout:
I have a screen that contains a list of items (attachments), which can be images, text or pdf. When the user clicks on one of these items - it will make a call to a controller action [ViewAttachment] which will return the requested item and display it in the iframe.
This currently works for all data types with the exception of PDFs in IE. (Firefox, Chrome etc. all display the PDF in the iframe without issue.)
I previously was using Adobe Reader 9, and recently upgraded to 10 in hopes of solving this issue. I'll attach some code to see if anyone has any suggestions as to how to possibly resolve this.
Code to Populate iframe: (Moved to two lines for readability)
$(".viewattachment").live('click',function ()
{
$("iframe#test").attr("src","<%=Url.Action("ViewAttachment","Images") %>?
attachment=" + $(this).next().val());
});
ViewAttachment Controller Action:
public ActionResult ViewAttachment(string attachmentGuid)
{
Attachment attachment= imageAgent.GetAttachment(attachmentGuid);
Stream resultStream = new MemoryStream();
resultStream = StorageProviders[attachment.ProviderName]
.ReadFile(attachment.FileReference);
resultStream.Position = 0;
FileStreamResult result = new FileStreamResult(resultStream,
attachment.ContentType);
return result;
}
Notes:
I've attempted toggling the "Display PDF in Browser" in Adobe Reader without any success.
Currently testing this for IE8.
When clicking on a PDF to view - the iframe simply remains at it's previous content and doesn't change at all.
After several different methods and iterations of testing - I determined that it was a conflict between IE8-9 and versions of Adobe Reader 9-10. I added the following meta tag to the window containing the iframe and it resolved all of the issues:
<meta http-equiv="X-UA-Compatible" content="IE=7" />
This should at least work until an update / fix is made.
Have you tried hitting the pdf url directly? If it loads within the browser, then you can narrow down the problem to the iframe. If Adobe Reader pops up, then you know its a problem with the IE Plugin.
I had the same problem working with spring mvc. I releazed that if I put the Iframe inside some tag, like 'util:panel', the iframe does not load de pdf content in IE 8. When I put the iFrame out of the tag, all work fine.
How do I (in my controller) send a pdf that opens in the browser. I have tried this but it only downloads the file (both ie and firefox) without asking.
public ActionResult GetIt()
{
var filename = #"C:\path\to\pdf\test.pdf";
// Edit start
ControllerContext.HttpContext.Response.AddHeader("Content-Disposition", String.Format("inline;filename=\"{0}\"", "test.pdf"));
// Edit stop
return File(filename, "application/pdf", Server.HtmlEncode(filename));
}
After adding the edit above it works as it should, thanks.
You need to set the Content disposition HTTP header to inline to indicate to the browser that it should try to use a PDF plugin if it is available.
Something like: Content-Disposition: inline; filename=test.pdf
Note that you cannot force the use of the plugin, it is a decision made by the browser.
This (in addition to the other headers) does the trick for me in a plain .net web app:
Response.AddHeader("Content-Disposition", String.Format("inline;filename=""{0}""", FileName))
I'm not familiar with MVC, but hopefully this helps.
I think this relies on how the client handles PDF files. If it has setup to let Adobe Reader open the files in the browser plugin it will do that, but maybe you have set it up to download the file rather than opening it.
In any case, there is no way of controlling how PDF files will be opened on the user's machine.
