Does loadDataWithBaseUrl pick all .css and .js files from assets in order to load the page?

so basically I am not understanding if in order for this method to load the page correctly as loadUrl(any_url), I must include all files required (css. js, etc) in the assets while calling:
webview.loadDataWithBaseURL("file:///assets/", htmlData, "text/html", "UTF-8", null);
I ask this because I needed to substitute/add only ONE .CSS file before loading the page, but it seems loadDataWithBaseURL uses only the files in "assets" and the html itself.

How to load local html pages to android

I want to load local HTML pages in to a WebView. I know how to do it in iPhone. Can any one tell me the way to do it in android.
How to do the below page in android?

put your file to asset folder than you can use the code below
WebView webview = (WebView) findViewById(R.id.yourwebview);
webview .loadUrl("file:///android_asset/UI/mylocalhtmlfile.htm");

use this.
yourWebView.loadUrl("file:///android_asset/yourfileName.html");

Create a TextView textArea and set it's text with the html string
You can define the string as a part of strings.xml file with your html tags and make sure you call getText(T.string.your_html_string) to fetch the html based text
<string name="your_html_text">"Press <font fgcolor="#ffffffff"><b>Menu</b></font> and touch:\n
\n<li><font fgcolor="#ffffffff"><b>Create </b></font> to create\n</li>
\n<li><font fgcolor="#ffffffff"><b>Delete All</b></font> to delete all\n</li>
</string>
and setText like
textArea.setText(getText(R.string.your_html_text));

The easiest way would probably be to put your web resources into the assets folder then call
webView.loadUrl("file:///android_asset/filename.html");

Android Development: Using Image From Assets In A WebView's HTML

In my app I'm making a basic HTML help document.
I wanted my app's logo in the HTML img tag itself, but I don't know how I'd reference to the logo which will be stored in assets.
Is this possible, if so how?
Thanks for the help!

Put your Logo into the assets directory eg: assets/logo.png
Then load your html with:
webView.loadDataWithBaseURL("file:///android_asset/", htmlData, "text/html", "utf-8", null);
Reference your img like:
<img src="logo.png">

Store the images in assets folder:
Read the image in the html from assets with file:///android_asset/
for example:
String sHtmlTemplate = "<html><head></head><body><img src=\"file:///android_asset/img/mybadge.png\"></body></html>";
load inside the WebView:
webView.loadDataWithBaseURL(null, sHtmlTemplate, "text/html", "utf-8",null);

You can reference assets with this URL syntax:
file:///android_asset/YourAssetFilename

dump them into assets folder and just put in the html
<img src="filename.png">
simple as that

Put your Logo into the assets directory
Example : assets/logo.png
Then
String imgData="<img src=home.png>";
webView.loadDataWithBaseURL("file:///android_asset/", imgData, "text/html", "utf-8", null);

Consider we have placed an image your_image.png in assets/imgs.
In earlier versions of android you can directly access images like below.
webView.loadData("<img src='file:///android_asset/imgs/your_image.png'/>",
"text/html", "UTF-8");
But can't access files directly in latest versions due to added security concerns. for the latest versions we need to use WebViewAssetLoader. refer the below code.
Helper class to load local files including application's static assets and resources using http(s):// URLs inside a WebView class. Loading local files using web-like URLs instead of "file://" is desirable as it is compatible with the Same-Origin policy.
final WebViewAssetLoader assetLoader = new WebViewAssetLoader.Builder()
.addPathHandler("/assets/", new WebViewAssetLoader.AssetsPathHandler(this))
.build();
webView.setWebViewClient(new WebViewClient() {
#Override
public WebResourceResponse shouldInterceptRequest(WebView view,
WebResourceRequest request) {
return assetLoader.shouldInterceptRequest(request.getUrl());
}
});
webView.loadData("<img src='https://appassets.androidplatform.net/assets/imgs/your_image.png'/>",
"text/html", "UTF-8");
