Android Question MobilevisionEx and fileprovider URI error

[saunwin]

Hi,
I'm (trying) to use MobileVisionEx with sdk target of 28 and I get a URI error. This is documented in other threads and fileprovider is suggested as a solution.
I have fileprovider/filepicker loaded, modified the manifest, but just keep getting errors.
I'm obviously missing something
Anyone help pls ?
TIA

1. Please use quote tags for logs.
2. Where is the sample project which shows the correct use of FileProvider?
3. As the project is from 2017 i can imagine it is not using any high targetsdk. Looking at the old project i see targetsdk 22 in the Manifest.

That said i did look at the Librarysource and found out that there are methods used which are not possible with targetsdk 23+.

The problem is in the githubproject which is not updated since years.

I suggest not to use the lib anymore.

Hi DonManfred, Thank you for your reply.
Quote tags for logs - Noted thank you.
The minimum target sdk for play store is now 28, so I'll have to think again.
Thank you
