Problem with HTMLview on Android

[PEB]

Is anyone able to use the HTMLview class on android devices? Even just using the HTMLview example from the RapaGUI package doesn't work for me. I always get:

"Webpage not available"
"net::ERR_CLEARTEXT_NOT_PERMITTED"

In the past, I had gotten around this by adding...

Code: Select all

android:usesCleartextTraffic="true"

...to the manifest in the APK compiler; but now that doesn't seem to help.

Any ideas?

Update:
The website for wikipedia ("http://www.wikipedia.org/") does load, but no other website seems to work.
Also, local .html files do not display either.

Right, I can reproduce this here. Will be fixed.

Thanks, Andreas, for working on a fix for this issue.

If htmlview in android tweaked
There are some other "tweaks" to enable javascript and loading local files whre would be very handfull if they also implemented

Has anyone figured out a workaround for this problem yet?
Or do we need to wait for the next release of RapaGUI?

I'm afraid I don't see how this can be worked around. But in the next version it'll hopefully be fixed.

No worries.
Thanks for working to fix this.

I've done some research and tried it myself. I don't think I can do anything against the way HTMLview behaves on Android but I do managed to get it to open all websites by setting "android:usesCleartextTraffic" to "true" in the manifest. Are you sure that this is really not working for you? It seems to work here.

Without setting "android:usesCleartextTraffic" to "true" only sites work that use HTTPS instead of HTTP, with the exception of Wikipedia maybe. So you could also work around problems by simply prefixing URLs with https:// prefix instead of http:// Most websites are available as HTTPS anyway nowadays.

Also, local .html files do not display either.

How do you try to show local files? Since all apps run in a sandbox it's very difficult to access local files from within your apps. I don't think there's any way to access files outside the app using the HTMLview widget. AFAIU it's only possible to show local files that are stored as assets in your APK, e.g. like this:

Code: Select all

moai.Set("htmlview", "url", "file:///android_asset/filename.html")

Showing any local files OUTSIDE the project's asset folder isn't really possible at all I think.

does the above "fix" also allow executing local javascipt ?
i think you must enabled by code
