android Not allowed to load local resource:file:///android_asset
(5 answers)
Closed 9 years ago.
I load html files from remote server and show them in webview but default font face for my language is a bit messy so I tried to load fonts from asset folder. here are my java code and html file.
webView.getSettings().setAppCacheEnabled(false);
webView.getSettings().setAppCacheMaxSize(1);
webView.getSettings().setDomStorageEnabled(true);
webView.addJavascriptInterface(new WebAppInterface(this), "Android");
webView.setWebViewClient(new MyWebViewClient());
isShowing=true;
dialog.show();
String address="http://server/test.html";
Log.d("checking", address);
webView.loadUrl(address);
html code:
<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title> Title Here </title>
<style type="text/css">
#font-face {
font-family:nazanin;
src:url('file:///android_asset/fonts/BNAZANIN.TTF');
}
body {
font-family: nazanin;
font-size: medium;
text-align: justify;
}
</style>
</head>
<body>
<p>this is for test</p>
</body>
</html>
the problem is after loading I got this error:
11-21 10:50:55.439: E/Web Console(9572): Not allowed to load local resource: file:///android_asset/fonts/BNAZANIN.TTF at :0
what is the solution for this?
I end up adding that font on server and link to that in html file. I tried almost any ways and I think this is the only way that works. LoadDataWithBaseUrl and adding font in asset folder is not the way when you have external files like css and js to use in html.

Problem:
I should display offline a Html page stored in my react-native app, and for to do it I used WebView:
<WebView
originWhitelist={['*']}
source = {{uri:'file:///android_asset/index.html'}}
/>
but it load just html file without css and/or js, this is an example of my html page:
my file html is stored in: react-native-project->android->app->src->main->assets->web
<!DOCTYPE html>
<html>
<head>
<link rel="stylesheet" type="text/css" href="css/styles.css"/>
</head>
<body >
<h1>Hello World</h1>
</body>
</html>
this is an example of my css page:
my file css is stored in: react-native-project->android->app->src->main->assets->web->css
h1 {
color:red;
}
I have found this post on medium but not work for my and BaseUrl not work.
Question:
How I can display a Html page with relative file css and js connected to it offline on react-native?
can I use the cache how do react-native-offline-cache-webview ?
Thanks for your attention and sorry if my English is wrong but I'm not a native speaker bye
I'm working on a reader, and we used to work on epub2, and I working on pagination effect using CSS file. I have recently received an ePub 3 file and it does not abide by the CSS rules that I have provided, although it works correctly when tried on Play Books android app.
Note that I have manipulated several features related to web view such as:
testWV.getSettings().setUseWideViewPort(true);
testWV.getSettings().setLoadWithOverviewMode(true);
and this is the paging CSS used which as mentioned before works perfectly on epub2 files
html {
height:heightplaceholderpx; //set dynamically depending on phone screen size
width:100%;
}
body {
margin:0px;
padding:0px;
width:100%;
pointer-events: none;
}
#viewer {
width:widthplaceholderpx;
height:heightplaceholderpx;
}
#book {
width:widthplaceholderpx;
height:heightplaceholderpx;
margin-left:50px;
margin-right:50px;
margin-top:10px;
-webkit-column-count:auto;
-webkit-column-width:widthplaceholderpx;
-webkit-column-gap:100px;
text-align:justify;
}
.h {
margin-top:60px;
margin-left:100px;
margin-right:100px;
}
img {
max-width: 100%;
height:auto;
}
This is how I'm integrating the CSS file:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<link rel="stylesheet" href="columnPaging.css" type="text/css" media="screen"/>
headplaceholder //the header extracted from the xhtml file of the book
</head>
<body>
<div id="viewer">
<div id="book">
bodyplaceholder //the body extracted from the xhtml file of the book
</div>
</div>
</body>
</html>
Like you can see you use this var widthplaceholderpx in his css. Normally it should be override it in the Java code. But when the bodyplaceholder was add to the body in the HTML I needed to override the widthplaceholderpx again. So the css would know what the actual height was.
Actually I want to load complete site from internet link but i want to load css files from mobile (means not from internet). Because I want to load all page faster using internal local css file.
Example :
<!DOCTYPE html>
<html lang="en">
<head>
<link rel="stylesheet" href="dist/css/bootstrap.min.css" />
<link rel="stylesheet" href="dist/css/font-awesome.min.css" />
</head>
</html>
So Here I want to Load "bootstrap.min.css" and "font-awesome.min.css" from mobile memory only.
My Android Code :
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
String url = "http://www.MySiteName.com/";
view = (WebView) this.findViewById(R.id.webView);
view.getSettings().setJavaScriptEnabled(true); // Enable JavaScript Support
view.setWebViewClient(new WebViewClient()); // Links open or Navigate in same webView not in Browser
view.loadUrl(url);
}
Please put CSS in assets folder, and refer to CSS by relative path, and load HTML to WebView by loadDataWithBaseURL() method:
if your css file name is mycss.css
StringBuilder data = new StringBuilder();
data .append("<HTML><HEAD><LINK href=\"mycss.css\" type=\"text/css\" rel=\"stylesheet\"/></HEAD><body>");
data .append(tables.toString());
data .append("</body></HTML>");
webView.loadDataWithBaseURL("file:///android_asset/", data .toString(), "text/html", "utf-8", null);
thank you
Because the two other answers are just copy pastas and I happened to have the same issue I will help you with my solution:
You need to specify the file path in the head section of your html file.
Pay attention to the part after href
<!DOCTYPE html>
<html lang="en">
<head>
<link rel="stylesheet" href="file:///android_asset/bootstrap.min.css" />
<link rel="stylesheet" href="file:///android_asset/font-awesome.min.css" />
</head>
</html>
I just can't get my head around why the other posters just copied and pasted and didn't even read what you were trying to tell them.
I hope this helps.
Be aware that your resources folder can be named differently.
I am working on an application with many html pages. I have created these in the raw folder on Eclipse.
I'm going to be making many html files and I want to have only one location for the css file which I want to call in each of the html files. This application works in such a way that the
loadData method displays the html page as shown below:
webview.loadData(readTextFromResource(R.raw.gen1), "text/html", "utf-8");
Id appreciate any ideas.
you can copy html and css files in your project assets and load html file from asset to webview like below code:
WebView wv;
wv = (WebView) findViewById(R.id.webView1);
wv.setBackgroundColor(0);
wv.setBackgroundResource(android.R.color.black);
wv.setWebChromeClient(new WebChromeClient());
wv.setWebViewClient(new WebViewClient());
wv.getSettings().setJavaScriptEnabled(true);
wv.getSettings().setPluginsEnabled(true);
wv.loadUrl("file:///android_asset/Index_Animation/test.html");
like below screen shot:
and refer css in html file below:
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html><head><meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<link rel="stylesheet" href="./style.css" type="text/css" media="screen"><!--This line refer the css file-->
</head>
<body bgcolor="#000000">
<div class="col_left">
<div class="logo">
<div class="circles">
<div class="circle"></div>
<div class="circle1"></div>
<div class="circle2"></div>
</div>
<center>
<img src="./Untitled.png" />
</center>
</div>
</div>
</body></html>
I have seen various discussions on the problem of serving WebView pages from assets, none of which seemed definitive.
I want to be able to use a webview to display html (and included css) files stored in the project assets.
I have found that wv.loadUrl("file:///android_asset/html_no_copy/demo_welcome.html") displays that file okay, but links in demo_welcome.html, either local (no url prefixing the file name) or absolute - the same form as fed to loadUrl - don't work. They get a "Web page not available" error displayed on the view.
WebView wv = (WebView)this.findViewById(R.id.splashWebView);
wv.loadUrl("file:///android_asset/html_no_copy/test.html"); // Works
or
wv.loadUrl("file:///android_asset/html_no_copy/demo_welcome.html"); // Works
But neither of the following links in demo_welcome.html work:
CLICK HERE<p>
OR HERE
I know I can get around this by writing a content provider, but that seems extreme.
I want this to work from SDK 1.6 (4) on up.
Does anyone know if this can be done with just HTML, or does one need to kluge up some code to load the data?
Well, I found something that seems to work (on 1.6 and 2.2), in spite of a warning that it would recurse.
I also discovered that a css style-sheet link inside the first and second page both work without the following intercept. Odd and it makes me a bit nervous. Thoughts?
Here's the code:
WebView wv = (WebView)this.findViewById(R.id.splashWebView);
wv.setWebViewClient(new WebViewClient() {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url)
{
view.loadUrl(url);
return true;
}
});
wv.loadUrl("file:///android_asset/html_no_copy/demo_welcome.html");
Here's the file contents:
demo_welcome.html:
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>Demo Html</title>
<link rel="stylesheet" type="text/css" href="demo.css" />
</head>
<body>
<H1>Testing One Two Three</H1>
CLICK HERE<p>
OR HERE
</body>
</html>
test.html:
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<link rel="stylesheet" type="text/css" href="test.css" />
<title>Insert title here</title>
</head>
<body>
<H1>TEST.HTML</H1>
</body>
</html>
instead of loadUrl, try using the loadDataWithBaseURL method:
wv.loadDataWithBaseURL("fake://not/needed", html, mimeType, encoding, "");
