Open vedsahani opened 5 years ago

vedsahani commented 5 years ago

I am using react-native-documentscanner-android. I have done all steps and camera is opening with write storage permission but scanning is not working. Please help, I got stuck from last two days. <DocumentScanner onPictureTaken={data =>{ console.log(data.path) }} onProcessing={() => alert(11)} enableTorch={false} detectionCountBeforeCapture={10} style={styles.scanner} />

Did you incude the 

include ':openCVLibrary310'
project(':openCVLibrary310').projectDir = new File(rootProject.projectDir,'../node_modules/react-native-documentscanner-android/android/openCVLibrary310')

this is the main think you have to do . Please give more informations.

I'm also faced with the same issue. I tried to fix it, but nothing help :( RN version: 0.57.8

In LogCat I see only one error: "Cannot load info library for OpenCV".

OpenCV included in a project and I did all that should in the manual install. Camera opened, but scanning isn't happening...

So, After a few hours, fixed this bug. It consists of two parts. Explain: 1) Problem is in the "main/jniLibs" folder. You should add all the architecture OpenCV libs. (downloaded it from here https://opencv.org/releases.html) 2) I faced with java.lang.RuntimeException: takePicture failed error. Problem is in file OpenNoteCameraView.java. I can't find what is this problem, but when I revert to the previous version – it has gone. Hope it will be helpful to you. Maybe one day I'll have more time, I can find a solution for the second problem and do PR.
