Bug? Webview - HTML access to files in subdirectory

[Jack Cole]

In the past, I was able to run HTML5/JS apps in a webview with b4a from the assets folder. At some point, it appears that a change was made that makes it where the HTML cannot access files in subdirectories of the assets folder. Seems like this might have been around the time when file groups were added, but I'm not sure about that. I am aware of workarounds for this, but these are less than ideal for large apps (3000+ files that would need to be unzipped into the internal files folder).

Is this a bug or intended for some reason? This is not backwards compatible with large projects that I have.

See attached example. I have just a simple HTML page that tries to load an image from a subdirectory (doesn't work).

The change is explained here: https://www.b4x.com/android/forum/threads/problem-with-files-in-folders-asset.132610/post-837649
It is a change in the behavior of the underlying packager tool.

In the linked post you can see the code to access a subfolder file from your code. In your case you need to change it in the html source:

<img src="subfolder%5Cicon.png">

%5C is the url encoded value of \

It is not very practical to do this with my apps. This is a massive number of file references. Also, this applies to any external js files loaded. If there is a way to fix this on your end, it will probably save you future support problems. Unless you just recommend never using HTML from assets. Still, this would be not optimal if a fix is possible.

d. If there is a way to fix this on your end,

No. This is how AAPT2 behaves.
