unable to use hid in kivy python mobile application

[lakshyacis]

As I am creating an app in kivy python using buildozer a wrapper for python-for-android where a buildozer.spec file needs to be maintained and I simply wrote hidapi as requirement but it seems not working when says import hid

Please see #373.

You didn't provide you build log/error message/build environment/etc. Not enough info to know what exactly help do you need.

ImportError: Unable to load any of the following libraries:libhidapi-hidraw.so libhidapi-hidraw.so.0 libhidapi-libusb.so libhidapi-libusb.so.0 libhidapi-iohidmanager.so libhidapi-iohidmanager.so.0 libhidapi.dylib hidapi.dll libhidapi-0.dll

As I got to know these cant be installed using pip as they are not in pypi as I tried the installation of these in linux system where they got installed using

sudo apt-get install libudev-dev libusb-1.0-0-dev libfox-1.6-dev

sudo apt-get install libhidapi-hidraw0

so How can I manage it in spec file do guide me

kivy python mobile application

are you trying to build/run you application on some mobile platform?

sudo apt-get install libhidapi-hidraw0

this should be more than enough to run hidapi/python application on your host Linux system

yes its working on linux fine but the thing is for mobile phone application I am using kivy and buildozer and buildozer uses its spec file for making apk and build libraries and as these requirements are not available on pypi so it cant be installed using pip so how can I manage I am little bit confuse

You have to use Android NDK to build hidapi to get libhidapi-hidraw.so/libhidapi-libusb.so and package it into your APK. To build libhidapi-libusb you'd also need to build libusb with same Android NDK first.

This one is entirely on you.

Hey! i got exactly the same error on windows. What solved your problem? Its not clear to me at all.. spend a lot time with the hidapi lib now but no success. Would be amazing to get some help.

it seems like "hidraw" is the problem but i cannot find a workaround..
