android-armebi-v7a, arm64-v8a, Armebi's pits

First, a wave of literacy:

Armeabi: for normal or old arm v5 CPUs

armeabi-v7a: arm v7 CPUs (32-bit ARM devices) with floating-point arithmetic or advanced expansion capabilities

arm64-v8a:64-bit ARM device

Android L only really support 32-bit and 64-bit art virtual machines, with 64-bit processors, justify running 64-bit software

Compatibility and file read order

ARM64-V8A can be backwards compatible, with Armeabi-v7a,armeabi under it.
ARMEABI-V7A backwards compatible Armeabi

For a CPU is the ARM64-V8A architecture of the phone, when it runs the app, go to Jnilibs to read the library file, first see there is no arm64-v8a folder:

If there is no such folder, go to the armeabi-v7a folder, if not, then go to the Armeabi folder, if not even this folder, throw an exception
If you have a arm64-v8a folder, then go to the. So file for a specific name, Note: If not found, no further down (armeabi-v7a folder), but directly throw an exception
