Support 64-bit processors

[vkochar]

The sdk cannot scan card on a Nexus 9. Could you please add support for 64bit processors and other architectures.

[braebot]

Do you receive an error, or does the scanner fail to initialize? Some logs might be helpful in determining whether the processor is supported or not.

The logs are below

The Nexus 9 does not have a ARMv7 processor, so scanning does not work. Its mentioned here that card.io requires ARMv7. I would like to request support for processors that are based on architectures other than ARMv7.

Thanks!

[braebot]

Thanks for the logs. Non-ARMv7 processors are not currently in the development pipeline. But, you're welcome to hack away at the source yourself in the open source repo.

Fixed in 5.0.1.

Hi,

Thanks for the update on this. But I'm not able to get it working with 5.0.1. There is a different error now.

I tried building card.io with libcardioDecider for arm64-v8a and I get the error in my first post again.
Am I missing something.?
Thanks!

[braebot]

Well shoot. We tested this on an S6, and the fallback to v7a worked. I'm not sure what's going on with the Nexus 9. I'll reopen this issue until we can figure it out.

[jmaffre]

Hey @braebot, I have the same error as @varunkochar (couldn't find "libcardioDecider.so") on an S6 when I include an other third party lib which use arm64-v8a folder.
When I remove the other lib, it's fine so It seems that the fallback to the folder v7a occurs only if you don't have the arm64-v8a folder at all.

@braebot I have the same error on Samsung Galaxy Tab 3
We already use the latest version
is there any solution ?

[ayltai]

Same case here. On S6, with another 64bit library in arm64-v8a folder, card.io will not work with error ERROR_NO_DEVICE_SUPPORT: This device cannot use the camera to read card numbers

[ghost]

@braebot Can you please give us any feedback from your side?

[corbt]

Hey, I'd just like to mention that I'm hitting this same error on a nexus 9. The logs are below in case they help.

I'm happy to run any tests or provide any further details needed in adding support for the Nexus 9.

Not working on galaxy s4 and nexus 4/5. getting the folowing output:

I/card.io: card.io 5.0.1 06/04/2015 17:39:33 -0500

please give a help

[braebot]

We need to add 64 bit support. I've renamed this issue accordingly.

[corbt]

@braebot if you're wondering why the fallback worked for you in testing on an S6 and it's not working for some of us in the wild, it may be related to this answer on Stack Overflow. Basically if a project already has some 64-bit dependencies Android won't load 32-bit native libs.

[braebot]

Thanks for the info @corbt! We found this to be the case as well through some trial and error. It's unfortunate it wasn't publicized.

[corbt]

Hey everybody, for those still struggling with this issue, after further investigation I've found a (very sub-optimal) workaround that I've tested and found to work on my Nexus 9. I wrote it up in a blog here. I'm still hoping for a 64-bit version of card.io, but at least this works in the meantime.

[zsavely]

@corbt Thanks for your post. It works

[braebot]

Fixed in release 5.1.0. Thanks!
