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

I'm trying to create a Delphi 11 app for Android 12, which opens a local HTML file with local images.
The local HTML file is stored here:
content://com.embarcadero.MyAppDir/fileprovider/external_public_files/MyAppDir/Pics/MyFile.html
The local images are stored in the same local directory.
I can get Chrome and other browsers to open the HTML file without any problem, except that none of the images are displayed. Instead of my images the browser simply shows small icons with a broken corner, indicating an error.
None of these work for me:
<img src="mypic.jpg"/>
<img src="/storage/emulated/0/MyAppDir/Pics/mypic.jpg"/>
<img src="com.embarcadero.MyAppDir/fileprovider/external_public_files/MyAppDir/Pics/mypic.jpg"/>
I just don't know what else to try after src=.
content://com.embarcadero.MyAppDir/fileprovider/external_public_files/MyAppDir/Pics/MyFile.html
That is a content scheme uri.
You added a grand read permission to the intent so the browser could read the html source using the uri.
>><img src="mypic.jpg"/>
That is the src attribute that you should use.
Now the browser will try to read the image after having build an uri for it. The uri the browser build will be:
content://com.embarcadero.MyAppDir/fileprovider/external_public_files/MyAppDir/Pics/mypic.jpg
But unfortunately the browser has no read permission for this uri as you did not give it in the intent. (Not that it would be possible to do so).
Yes the old times were better. A browser just changed /path/file.html to /path/picture.jpg and all worked.
I have a simple image in my html which renders fine on my PC, but not on my smartphone:
<div id="welcomebox">
<img src="geschenk.jpg"/>
</div>
my folder-structure is as follows:
C:/Maus
- index.html
- geschenk.jpg
on my smartphone I copy that folder to my download-folder and open index.html from there. There's no web-server included, I directly open the file from the filesystem.
But on my smartphone the image isn't displayed.
Chrome will receive a content scheme from the Files app like:
content://com.google.android.apps.nbu.files.provider/1/file:// ...../index.html
As soon as Chrome 'sees' a content scheme it cannot display pictures as even if Chrome changes the scheme to:
content://com.google.android.apps.nbu.files.provider/1/file:// ...../geschenk.jpg
the provider will not let it access as there is no read permission for it.
The Android filesystem structure can't open relative file paths the same way other systems do.
So the answer is you need to use a complete hardcoded file:/// path.
This is not a very good approach since you need to replace all the URLs/paths in your HTML files.
Another approach if you are determined to do so, you can upload all project resources such as images, CSS, javascript to the cloud, like using SDN to access those files and to let the project work. But using the SDN approach it's easier to upload everything including the HTML files to a hosting account.
im a new android developer.
My app has WebView which loads lot of data from my site (which has pics, css, JS files).only the html code is updated weekly. other files are almost never changed. so i was thinking of including these static files in android assets, loading only the html from server and other files from assets and cutting down the loading time. how do i do it.
Android WebView Javascript from assets
and as shown in the above solution i cant change the html code to load these from assets because this site will also be accessed by web users.
Is there a way to do this. Thanks in advance..
Firstly you need to have relative paths
<img src="images/someimage.png">
not
<img src="www.mysite.com/images/someimage.png">
Then you need to load the HTML code not using webBrowser, for example like here
And then you can load HTML source into WebBrowser using base URL pointing to your assets like here
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.
I have a script that pulls an image from SQL Server and displays it as a link or on a page. Works perfectly in a browser and on most mobile devices. However, when linking directly to the aspx file link Android phones download the content but don't recognize the extension as an image, so they just save in the downloaded items folder as an image with an .aspx extension.
How can I cause Android devices to recognize the fileStream as an image instead of an object to be downloaded?
Thanks
I just tested a simple HTML file in the browser:
<!DOCTYPE html>
<html>
<body>
This is a test!<br/>
link
</body>
</html>
When I click on the link, the image is displayed in the browser (not downloaded).
The problem must be that imagehandler.aspx is not sending an appropriate set of headers. Maybe the script is not setting a Content-Type header, or the wrong value, or it is sending Content-Disposition attachment.
EDIT: This is what the browser app is getting:
