the important thing in the following code sample is "url: window.URL.createObjectURL(imgBlob),"

I hope this helps someone out there ;)

The last version (cordova android@8.0.0 /sdk 28) worked without problems. It looks like the cdvfile:// protocol is no longer recognized

> Thanks for your answer. The problem is not the path. Apparently the webview blocks the loading of local graphics into the html img src
You're right, you were using a particular part of the feature that I wasn't really familiar with.
I just tested this on `cordova-android@9` targeting API 29. I have an image file inside `cordova.files.dataDirectory + 'files/test.png';`
Which when I use `toInternalURL()`, it gives me `cdvfile://localhost/persistent/test.png` path. This works when used in the DOM, for as long as I update the CSP appropriately.
For me, my [fs root](https://github.com/apache/cordova-plugin-file#cdvfile-protocol) appears to be `persistent`, while your URL seems to have an fs root of `files`
If I change `persistent` to files, I do not receive the `ERR_UNKNOWN_URL_SCHEME`, but I do get a 404 Not found. I did receive `ERR_UNKNOWN_URL_SCHEME` if I use other `localhost/x` paths.
After moving the test image file to the proper place using `adb shell`, I see the `cdvfile://localhost/files/...` works properly for me.
I then created a sub directory and copied the image file, and determine it still works.
I then changed the `AndroidExtraFileSystems` defaults to omit the `files` file-system using:
`<preference name="AndroidExtraFilesystems" value="files-external,documents,sdcard,cache,cache-external,assets,root" />`
This is when I reproduced your issue. So I would check the `AndroidExtraFilesystems` preference and ensure you are including `files`

It looks like you took the full file path from another platform and saved it, then tried to use that file path on a different platform.
File paths differ from by platform, so you should be saving the relative URL part, eg:
```
localStorage.myImage = "cee8882b-650f-4107-88c3-5f84f90cbf36.jpg";
...
let myImage = localStorage.myImage;
let filepath = cordova.files.dataDirectory + myImage;
```
The above example hasn't been tested, but should give you the right idea. Let me know if this helps.
