I am trying to use the ePOS-Print SDK for Android.

It works fine on ARM Devices. Just not on x86 Devices.

Is the Library only working on ARM Devices or is there a way to make it work on x86 Devices?

I had a very similar error by trying to run an ARM app on Android x86. I was able to bypass it by installing libhoudini:

  1. On Android: Settings -> Apps Compatibility -> Enable Native Bridge
  2. Start Terminal Emulator (or press Alt-F1)
  3. Login as root: su -
  4. Run cd ~ /system/bin/enable_nativebridge
  5. Verify success by inspecting logs: logcat -T 10
  6. Reboot and re-install your ARM apps
