application not starting on Android 5.1

[benaryorg]

I was using a Fairphone 2 running Android 5.1, Rust (installed using multirust) v1.8.0.

Commands (used in android-rs-glue/examples/basic (5a8e33fd4d53a186e97dfd0fb8f6cabfcaf5b1d5)):

export PATH=$PATH:~/Downloads/apache-ant-1.9.7/bin:~/Downloads/icedtea-bin-3.0.0/bin:~/Downloads/android-sdk/platform-tools/
export ANDROID_SDK_HOME=~/Downloads/android-sdk/
export NDK_HOME=~/Downloads/android-ndk-r11c/
cargo apk

Which succeeded in creating an APK. Library: target/android-artifacts/build/libs/armeabi/libmain.so: ELF 32-bit LSB shared object, ARM, EABI5 version 1 (SYSV), dynamically linked, interpreter /system/bin/linker, not stripped

When then deployed to the phone using adb install -r target/android-artifacts/build/bin/rstest-debug.apk, I get this in logcat:

I'm getting the same error on android 6.0.

One thing I've noticed is that the path of the library is lib/armeabi/libmain.so inside the apk, but the error say it cannot load the library from lib/arm/libmain.so

Is this expected or the root cause of the bug? Is the path different in different versions of Android?

Notice: I haven't had access to the phone on which I could reproduce this so anyone being able to reproduce this is very welcome to take over this issue.
