You have to use older branch tree before the last update this one there is a bug as workaround you have to enable the camera permission in your phone app or you add the permission in your code

[jatankshirsagar]

I am using it in Android and hence I am directly using implementation 'com.github.adityaarora1:LiveEdgeDetection:master-SNAPSHOT' and due to which how can I shift to the previous commit.

here You can just restore theses 3 files he changed

Edit : this crash only happen on android 5 and above. But works fine on android 4 Few things to keep in mind :

• The quality image taken sometimes suck (because the scan doesn't wait to set auto focus before taking picture)
• This is only work dark background algorithm limitation
• Auto scan need delay before taking picture
• And it only works on portrait mode not landscape (Orientation angle)

In ScanUtils Activity he is not not calling theses I suspect they may fix the orientation angle issue determinePictureSize(); getDisplayOrientation(); getOptimalPreviewSize(); resize();

Android Device : One Plus 3 Os Version : 9

after making changes in the file getting the above error

[DerrickRocha]

I keep seeing this error as well. Is there a work around yet?

[ka05]

@jatankshirsagar, @DerrickRocha, @zakblacki I have been able to fix this by updating the OpenCV version from 340 to 343. I have created PR #42

[adityaarora1]

Should work now.
