Webviewer not showing Math Equation

[Jeprie]

I tried to display math equation using jqMath in App Inventor using tutorial from Displaying Math Formulas (google.com). The WebViewer display ERR_FILE_NOT_FOUND. The same thing happens when using the aia file in the tutorial.

Are the links need to be updated?

The result is supposed to be like this.

Change URL to http://localhost/formula.html

I have changed the URL in GoToUrl to http://localhost/formula.htm. The WebViewer no longer display ERR_FILE_NOT_FOUND. It is now showing 404 Not Found.

[Jeprie]

When changed to html there is nothing shown up, empty.

Save file to ASD and read from ASD directory

I'm sorry what is ASD? How can I do that?

[dora_paz]

Application Specific Directory Try this way using FileTools extension

Improving, thanks. The html file has shown up but it is not converted into equation.

I guess the html file url is now correct, but not the url of the three files in the initial script variabel.

Fixed it, all instances of file:///mnt/sdcard are converted into http://localhost.

End result

New version

<link rel="stylesheet" href="**http://localhost**/jqmath-0.4.3.css">
<script src="**http://localhost**/jquery-1.4.3.min.js"></script>
<script src="**http://localhost**/jqmath-etc-0.4.6.min.js" charset="utf-8"></script>

Old version

<link rel="stylesheet" href="**file:///mnt/sdcard**/AppInventor/assets/jqmath-0.4.3.css">
