OpenCV dependency

[eakteam]

It would be great if this project implement the OpenCV natively in the code without needing the OpenCV to be externally downloaded/instaleed ?

I think it's license issue/incompatibility.

It is open source and it will works way to more faster and also great control via Native.

There is various ways to solve:

• embed opencv and use .aab files (already used on play store version)
• embed all opencv variants, making .apk huge
• selective build different archs with opencv embeded (for fdroid)
• build source code with only used functions, making size .apk extremely optimized

the main problem is lack of expertise... any code on this is welcome.

Shame for F-Droid developers for not implementing Split APKs. Fortunately Accrescent, modern and secure app store is coming.

As of now I think option 1 or 2 would be good choice.

As an update to this, Accrescent is now in alpha. Developers can submit apps after they're whitelisted, so it's not completely open just yet though. Hiccups - as with all alpha software - are probably to be expected.

If the project's interested, documentation can be found here:

https://accrescent.app/docs/index.html

Edit: It does seem like this app would probably need some changes/updates to be eligible though, such as the targetSDK being bumped up to 31+. I don't know if the project is active and willing to keep up with such updates in the long term.

I agree. I cant install opencv manager thing. it said my phone is not compatible.

[pokulo]

As mentioned above installing opencv manager does not work on e.g. Pixel 8a with Android 15 and ONScanner 1.0.35-fdroid. Installer popup sais, it is incompatible. Is this a cpu architectur compatibility issue with open cv binaries? Or is it maybe an Android SDK version issue or maybe just a stock google android permission issue?

[ildar]

this is the targetSdk unacceptable by modern Androids. But actually this can be overridden using ADB and the command:

adb install --bypass-low-target-sdk-block old.apk

I tried and it works for me. Though I'm not thrilled by the app itself. If someone wants to develop it further I'd make the issue report.

[PatrykMis]

@ildar Thanks for the tip!

[pokulo]

Thanks @ildar ! The outdated README prevented me from trying this earlier. But with the adb install --bypass… command OpenNoteScanner is working again.
