Android Question Access pics in file.dirassets from an html page.

[MitchBu]

My help file is an html in File.DirAssets, which uses a dozen or so pictures and video. I don't seem to be able to address them in HTML, although they are in files.dirassets together with the html page.

I suspect they are in compressed form, and need to be extracted somehow. I searched the forum to no avail, though.

Images loaded in webviews are not displayed in mode “debug (rapid)” B4A 3.50 version

In the new Basic4Android 3.50 version, I realised that images loaded in webviews are not displayed in mode “debug (rapid)”. In other modes, as “debug (legacy)” and “release” are shown normally. There is a simple example to check this: Sub Globals Dim WebV As WebView End Sub Sub...

Path to DirInternal to load picture in html webpage

Hello Inside my html page when I download It to assets directory the path to show picture is: src="file:///android_asset/house.jpg" What is the correct path if I download the webpage to DirInternal? src="file:///????/house.jpg"

Unfortunately, this does not answer my question.

I already use WebViewAssetFile to load the html file.

My question has to do with the html code, which needs to point to image files that need to be next to the html file in order to display.

Apparently, Android does not store the pictures files "as is", since they do not show.

I read carefully https://www.b4x.com/android/forum/t...g-rapid-”-b4a-3-50-version.38981/#post-230988 but even adding #DebuggerForceStandardAssets: true to the project, and compiling as Release, the html file does not find the pictures I added to DirAsset next to it.

I tried a small app with pics (in emulator). maybe there are things unnecessary, and works only in release mode.
Now works in debug mode with

#DebuggerForceStandardAssets: true


perfect.

I appreciate your help, rosippc64a

All I needed is src="file:///android_asset/

Now I will be able to do my help screen.

Thank you.

User XUI.FileUri, it's that simple...

WebView1.LoadHtml($"<img src="${xui.FileUri(File.DirAssets, "smiley.png")}" />"$)
'or:
WebView1.LoadUrl($"${xui.FileUri(File.DirAssets, "smiley.png")}"$)

'or:
WebView1.LoadUrl($"${xui.FileUri(File.DirAssets, "smiley.png")}"$)

what if files are in AssetDir/images/picture.jpg, i mean inside a folder in assets?
i tried

xui.FileUri(File.DirAssets & "/images","important-wr.png")
'and
xui.FileUri(File.DirAssets,"images/important-wr.png")

none worked, i don't want to drop my images folder to root, i have a lot of images and it will be a mess, also i have CSS and Javascript folders that cannot be accessed.

i don't want to drop my images folder to root,

It does not matter what you 'don't want', read my response below.

Simple, place ALL FILES in the root like you are supposed to.

You NEED to flatten the assets folder by placing all the files in the root folder directly. You're supposed to manage the images through the IDE via the Files Tab. You create new groups/folders via the files tab and manage the files and folder names there. It's as simple as that.

That can work, but if i have different images with same names in different sub folders, it wont work., i better followed Erel suggestion: add a zip and extract to Internal, i don't know why in B4A v10.70 the dir assets are broken and doubled the work for my webview apps.

There is yet another possibility: put all your pages on a web space.
