What is armeabi and why they use it?

Question

I see this library (armeabi) many times when I explore open sources.

I net searched for an explanation of it, but all the results I found are talking ABOUT it and not de

ABI - Application Binary Interface

EABI - Embedded Application Binary Interface

So ARMEABI are compiled binaries matching your android device's CPU architecture.

e.g.

arm64-v8a (Nexus 5x) - 64bit - ARM Cortex-A35, ARM Cortex-A53, ARM Cortex-A57, ARM Cortex-A72, ARM Cortex-A73

armeabi-v7a - 32bit - ARM Cortex-A5, ARM Cortex-A7, ARM Cortex-A8, ARM Cortex-A9, ARM Cortex-A12, ARM Cortex-A15, ARM Cortex-A17

To include *.so binary jniLibs using Android Studio 2.3 place them in src/main/jniLibs folder and add the following configuration to your *.gradle file:

android {
    sourceSets {
        main {
            jniLibs.srcDirs = ['src/main/jniLibs']
        }
    }
}

dependencies {
    compile fileTree(dir: 'jniLibs', include: ['*.so'])
}
