Off topic html and Android 10

DMike92 · June 23, 2021, 9:31pm

Sorry for this off-topic question but I know there is a lot of knowledge here (and, of course, I did'nt get anything on Google).

I have a local html file on my SD card (say page1.html) which is calling another one (page2.html) via a simple link (Page2)
Both files are in the same directory (/sdcard/genealogie)
The fist one is correctly displayed but when I click on page2 link, the browser (Chrome) says 'ERR_FILE_NOT_FOUND'

Depending on which applcation I start the first one, paths are différent:
With local folders app, I get for page1.html:
The first one: "content://0@media/external/file/3393"
and the second (shown in the address bar) "content://0@media/external/file/Page2.html" but not found.
And if I type "content://0@media/external/file/Page1.html" it say file not found (same error then with Page2)

Hope I clear enough.
I Know this is because of recent security changes on Android 10 (was perfectly working for years before) but I wonder how I can make it work?

Any ideas?

Any reason you are not using the webviewer?

How are you opening the first html file, with activity Starter?

There is a block (.GetUri) in Taifun's File Extension that converts a normal file path to a content uri. Have you tried that? (put in first html file as the link)

Thank you TIM for your answer despite it's "off topic".
The thing is: I don't use AI2 at all; All .html files are on my SD card in one directory and I use Chrome to open the index file there (same with built-in viewer).
The file opens nice and clean but all the links (to other local files) results in "file not found".
Links are in the form: <a href="file2.html">237</a> with no preceding path.

I can see the first file has the form 'content://0@media/external/file/3393'
And when I click, it becomes: 'content://0@media/external/file/237.html'.
Any ideas ?

What path do you use to open the "index" file?

You will probably need the same path/s in your html for the other files?

DMike92 · August 9, 2021, 10:34am

I just go with my brower ('My files') where the index is and click on the index.html file.
I can see the first file has the form 'content://0@media/external/file/3393'
And when I click, it becomes: 'content://0@media/external/file/237.html'.
Any ideas ?

You may possibly need to move the html files into one of the "media" folders, like Documents or Downloads.

I am am just doing some testing too.

OK
On android 10

I uploaded page1 and page2 html files to /sdcard/Download

Opened up page1.html in the browser using:

file:///sdcard/Download/page1.html

The file path to page2.html was simply that - e.g.

<body>
	<p>Hello this is page 1</p>
	<a href="page2.html">Open Page 2</a>
</body>

The same for page 2

<body>
	<p>Hello this is page 2</p>
	<a href="page1.html">Open Page 1</a>
</body>

and it worked

Not working on my Android 11 device....

DMike92 · August 9, 2021, 10:55am

I'll try that right now but I have to move the whole folder in Download as it has over 1,000 files in it.

DMike92 · August 9, 2021, 10:57am

That's right. It used to work nicely before!

You may have to install an http server....

DMike92 · August 9, 2021, 11:37am

I already read that somewhere else but I did not see why this. It's obviouly a misfunctionning in Android 11 (imo).

DMike92 · August 9, 2021, 11:38am

Thank you anyway

Requires a simple AI2 app with a webviewer but then all that is needed:

and relative file paths work OK

Tested Android 10 & 11 with companion. Also works with files in Assets (http://localhost/....)

DMike92 · August 9, 2021, 2:41pm

Whaou ! I'll try that soon.

DMike92 · August 9, 2021, 3:13pm

I tried it on internal storage and I got:
"The permission READ_EXTERNAL_STORAGE had been denied; Please enable this in the settings of the app." (event it's on the phone's memory)
Therefore I used:

But no change (does not ask for anything)

I'd like to have it on external storage (SD Card) but I'm unable to get the corresponding path!

DMike92 · August 9, 2021, 3:18pm

I also tried with:

But same message

You may have to manually give your compiled app permission (Storage / Media and Files )

DMike92 · August 9, 2021, 3:49pm

Ok, When I use my numbers (3135-3361) it gives me
net: ERR_ACCESS_DENIED
