为什么我需要在armeabi-v7a和armeabi文件夹中都放* .so文件? [英] why I need put *.so files in both armeabi-v7a and armeabi folders?

问题描述

我必须由其他人使用.so lib文件，并且有必要在两个文件夹中放入相同的文件.否则，安装不能保证将lib文件放置在/data/data//lib中. 为什么?

I have to use a .so lib file by others, and it is necessary put the same file in both folders. Otherwise installing can NOT guarantee the lib file be placed in /data/data//lib. why ?

推荐答案

实际上是不一样的. armeabi-v7a针对具有浮点操作支持的v7a版本进行了优化.使用armeabi-v7a作为目标设备，它将比不提供浮点运算支持的armeabi运行更快.可以在armeabi中打开库，也可以，但是如果您的应用程序在armeabi-v7a平台上运行，则无法利用目标CPU的优势.

Actually it's not the same. armeabi-v7a is optimized for v7a version which has float point operation support. With armeabi-v7a as the target device, it will run faster than armeabi which doesn't provide float point operation support. It's okay if you let your librariese on in armeabi, but if you can't take the advantage of the target CPU if your app is run on armeabi-v7a platform.

为您的本机库使用不同的分离目录将使您的应用程序更具可移植性，如果您希望您的应用程序在当前支持的任何Android设备或模拟器上运行，则应提供x86，x86_64，mips等.

Have the different separated directory for your native library will let your app more portable, you should provide x86,x86_64,mips, etc. if you want your app run on any Android device or emulator currently supported.
