Opencv manager not available although it is needed by some apps on F-Droid

#1

Opencv is a computer vision library used by a some apps on F-Droid, for example a note scanning app (Open Note Scanner) and a game app (Form-N-Fun). The two apps doesn’t include a binary/precompiled version of the library but uses it provided by Opencv Manager App which isn’t available of F-Droid and probably won’t ever be (https://gitlab.com/fdroid/rfp/issues/385).
I have tried to get the needed app, but I don’t have access to Google Play Store (Yalp/Aurora-Store broken, fix currently not available on F-Droid, don’t like to use Google Play anyway) and I can’t find a official compiled binary on GitHub or opencv.org (maybe because it’s deprecated or I can’t search :wink: ?).
Open Note Scanner has an automatic download for the missing apk but currently that doesn’t work on my smartphone.
How can I used the apps?
And isn’t it problematically if an app depends on other apps that aren’t available on F-Droid?
Currently I wonder wether or not were should be an anti-feature for such an situation – at least for Form-N-Fun that doesn’t has an automatic download but is showing a link that is only working for Playstore as long as Opencv Manager isn’t available on F-Droid?

Ok, I found the issue with the build-in download in Open Note Scanner doesn’t work: The power saving mode blocked the Android DownloadManager.

The NEW Aurora Store ( https://f-droid.org/en/packages/com.aurora.store/ ) works fine.

#4

OpenCV manager is still available as part of the complete OpenCV SDK download.
However, it it deprecated so these apps should stop using it and embed the OpenCV library instead.

@Licaon_Kter You are right. The new Aurora Store is working. But I can’t find the Opencv Manager App (org.opencv.engine). It doesn’t seem to be available on Play Store anymore.
@Rudloff I downloaded the whole SDK zip for Android and extract it (version 4.1.0), but it doesn’t contain any .apk-file.

The Opencv Manager App downloaded by Open Note Scanner is outdated and doesn’t work with Form-N-Fun.

It is only available in version 3 of the SDK.
