card.io doesn't work in production

Question

card.io works great when installed from eclipse. when installed exported apk the activity throws this: ERROR_NO_DEVICE_SUPPORT: This device cannot use the camera to read card numbers.

1. tried to disable proguard and export.
2. opened apk file to verify .so files are there in the correct folders under lib.
3. this is happening on 3 different devices, nexus 4, samsung s3, alcatel.

the project with card.io is a library project used by other android projects.

any ideas? thanks, sharon.

Answer 1

Please download the latest version (3.1.3+), as some older Android card.io versions had an issue in release mode.
