I’m not sure whether it is actually intended by the extension to store the HTML in the privateDir's cache. Can you clarify this please. → @TimAi2

Following your excellent storage graphic on Android, Anke, is not a bad place for creating a cache file, this path is ASD and dont need special permissions, or something has chaged in SDK30 about this ?

thansk for your support

#7

Yes, but it seems @TimAi2 saved in the privateDir (and I wonder about that).
Btw, please do not just post something that you did not create yourself, but link to it. (I’ll remove the image.)

#8

This was a carry over from the original extension by Mills College. I actually modified things so that the html was deleted after use.


File file = File.createTempFile("display", ".html");
            filePath = file.getAbsolutePath();
            FileWriter filewriter = new FileWriter(file);
            filewriter.write(htmlCode);
            filewriter.close();

            if(webViewer instanceof WebViewer){
                ((WebViewer) webViewer).GoToUrl("file://" + filePath);
            } else {
                ((WebView) webViewer).loadUrl("file://" + filePath);
            }
            file.deleteOnExit();

Ok, that wasn’t my question, but whether it is (was) cached in the privateDir.

Sorry, you are right, corrected now

#11

See here:

#12

Ok, but there are different temporary-file directories.
(e.g. in the ASD or in the privateDir)

#13

Not sure why the temporary saving of files is an issue?

The extension was targeted at AI2 and it works on AI2 companion and compiled. It was never expressly stated or intended necessarily for the extension to work on Kodular…

Hi, more test if this helps Kodular s developers with this issue:
Looks like the cached files exist in this privateDir 's cache path, take a look:

127|zeroflte:/data/user/0/io.kodular.xmanugu.graficas/cache # ls -la

zeroflte:/data/user/0/io.kodular.xmanugu.graficas/cache #

Looks like the extension create and write the file in this path, but later the webview component can not read inside, I guess.

Hope this helps Kodular 's developers, and thanks for your support.

Hi, looking for workaround, knowing that the issue is more related with WebView component, I found this great extension from Profile - lukegackle - Kodular Community, the:
http://thunkableblocks.blogspot.com/2017/06/webviewtools-extension-for-app-inventor.html

using only 2 blocks on the screen init to allow the webview file access give a workaround, thus solve the error access in Fenix 1.5.2.

If moderators consider, change the Thread tittle to something like “Webview error accesing cache dir in Fenix 1.5.2 Release”, maybe is more exact, nothing really related with ChartMakerPlus.
Thanks for your support.

Go to project settings and make sure Show Lists as json is checked. If it is not then check it, refresh creator and you will be able to see the chart
