java.lang.UnsatisfiedLinkError has unexpected e_machine: 40

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

I think you need build "libeposprint.so" file for x86.

I think this will help you

Put in gradle.properties this line

android.useDeprecatedNdk=true;

and in app/build.gradle this line in defaultConfig field

   ndk {
                abiFilters "armeabi", "armeabi-v7a","x86"
        }
