Android displaying html file with pictures and without internet connections - android

I would like to load a html file (with pictures and videos) on a Android tablet, however, there is no internet connection, thus I cannot use url for the pictures and stuff....
Is there any free web servers that allow me to do so (displaying the web content at local host)?
Or is there any way I can do it by writing a android app for it?
Thanks!!

Webview's LoadURL method can take local content. using the file uri retrieving the content from your assets and render it that way. Assuming you follow the standard folder structure for a basic HTML website.
And why would you want to ask about "free web servers" if you don't even have a internet connection... All the content has to be loaded locally on the app or downloaded on the fly (assuming you don't download too much.. if its too much then you are better off packaging it in the app).

Without Internet your html page is static page.
You can store the html file in your local assets folder then:
url = "file:///android_asset/" + mName + ".html";
mWebView.loadUrl(url);
and if you also want to show the images in your web page change the source path of images in source code of html page to local folder and pate all the images to that folder.

Image not loading on html file in android mobile

I'm trying to view my HTML file on the android mobile browser.
My HTML file has the following code:
<html>
<head>
<title>Testy</title>
</head>
<body>
<h1>Captain is Here</h1>
<img src='captain.jpg' width='30%' alt='Testy'/>
</body>
</html>
The image(captain.jpg) is also in the same folder where the HTML page is located. I'm getting the image on the computer browser but when I'm trying to open it in mobile browser image, not showing. I tried giving different file paths. How can I achieve this by giving a universal path by that a mobile that containing these HTML files should open in respective browsers and render images too?
1- your image size is too large try an image with a smaller size or resize or format your image into a smaller size.
try src-'./caption.jpg' instead of src='caption.jpg'
Opening through directry location of Html in Chrome Solve this.
For that get html file location directry in details by file manager
Example storage/emulated/0/web_folder/file.html and copy it
After that
1.Open chrome
2.type file:/// and Paste directry location
3."file:///storage/emulated/0/web_folder/file.html" Now it can run with image
Ensure that storage permission allowed to chrome
For that Open permission settings for chrome and allow storage permission
that's where mhtml and URLs get used!!!
Have you ever downloaded a page using chrome in android? if so you would have known about mhtml
MHTML, an initialism of "MIME encapsulation of aggregate HTML documents", is a web page archive format used to combine, in a single computer file, the HTML code and its companion resources (such as images, Flash animations, Java applets, and audio and video files) that are represented by external hyperlinks in the web page's HTML code
to convert your html to mhtml you may use some tools but you can also do it manually .
converting need not rename the file as index.mhtml but use all necessary files as hyperlinks
you may use image hosting sites like imgur or imgbb or even firebase if your familiar.
after you host get the link by
right-clicking image
open image in new tab
copy link
use it(link) instead of captain.jpg
Here is an example of how to get link using imgbb

How to store html page in xamp local server and use in android app

I am new for android server side..i want to store html page and images in xampp server and retrive it and show it in android app.
Your question is unclear.
for loading a HTML saved document, you must use WebView .
WebView can load html file saved in your assets file of your android application or from special URL like http://google.com
i did'nt know more about your question about xampp!
i think saving html pages in Xampp automatically is another discuss .

Load html page on webview without using a web server

Is there a way to load an html page on a webview without using a web server?
In my android application I have a web server because the user can save the web pages he wants and he can access them offline later.
I tried the assets folder but I cannot modify it at runtime. I can just read files I´ve put there.
To load online or offline I use the methods of the webview:
browser is the webview.
browser.setWebViewClient(new client());
browser.getSettings().setJavaScriptEnabled(true);
browser.getSettings().setDomStorageEnabled(true);
browser.getSettings().setJavaScriptCanOpenWindowsAutomatically(true);
browser.getSettings().setUseWideViewPort(true);
browser.loadUrl(url);
The url can be :
http://stackoverflow.com a normal one
or
http://localhost:8080"; //the web server inside the app
or from assets folder
files:///android_asset/file.html
But how I said, the use can save many pages and see it when he wants.
Is there a method to load the page saved in internal memory on the webview?
URL =this.getApplicationContext().getFilesDir()+"/www/file.html";
browser.loadUrl(URL);
For example: webview.loadString(); ?
Something like browser.loadUrl(Uri.fromFile(f).toString()) should work, for a File object named f pointing to your desired file. Uri.fromFile() will give you a Uri with the correct scheme; toString() gives you the string representation to hand to the WebView. I use this (or a variation) to read files on external storage. AFAIK, it should work fine for files on internal storage as well.

Unable to load local images in android webview

i am trying to load local images in android webview by using assets folder, but when i tries to open it, it is loading only HTML but not images
In my HTML Code i have added following line
<IMG SRC="file:///android_asset/images/a.jpg">
But it is not displaying image, can anybody please help?
put your images into the Assets folders by creating separate images folder like assets/images and then in your html page provide path of your image as
<IMG src="images/test.png">
first of which url loading in webview, is it local url or http (means requires internet). If ur loading local file system url pealse check the image path properly, it should work. if loading http url trying load a local images inside it sorry its not possible. Here its cross domain issue will restrict to that.

How do I save a complete webpage displayed in Android's WebView?

I am developing an Android application in which I have a WebView. I want to save the entire webpage loaded in this webview (Html + all resources + images + icons etc) into a folder and zip it and upload it to a server.
If you use WebView's saveWebArchive, then it is saved in archive format. How do I get the Html and images back from this archive? Is there any documentation for the format of this archive?
If I use addJavaScriptInterface to get the html as described here, I still have to copy the images and other resources from the webview cache dir (/data/data/your app package/cache/webviewCache/). However I did not find webview cache dir (/data/data/your app package/cache/webviewCache/) in Icecream Sandwich.
Is there a way to save the entire webpage displayed in webview along with resources in Android?
Thanks
If anyone is still interested, there is an open source project here that can read WebView's archive format (saved with saveWebArchive) and display it back in a WebView.
https://github.com/gregko/WebArchiveReader
I couldn't find details of the actual format yet.
You can use HTML 5 to store pages in the cache and load from the cache itself.
Caching is easy using HTML5, all you have to do is to make and refer a manifest file that holds information on what all elements need to be cached.
http://www.html5rocks.com/en/tutorials/appcache/beginner/
And here is a good way to implement the cache feature in your webview. http://alex.tapmania.org/2010/11/html5-cache-android-webview.html
