基于android eclipse的JNI 构建－常用命令笔记

今天又来搭建jni框架了，之前的那几个命令忘了。为了以后使用的需要，现在记录一下；

首先ndk环境ok；

cd 进入src目录下

返回上一个目录

cd ..

编译java文件



生成本地函数头文件

APP_ABI

By default, the NDK build system generates machine code for the armeabi ABI. This machine code corresponds to an ARMv5TE-based CPU with software floating point operations. You can use APP_ABI to select a different ABI. Table 1 shows the APP_ABI settings for different instruction sets.

Table 1. APP_ABI settings for different instruction sets.

Instruction set Value

Hardware FPU instructions on ARMv7 based devices APP_ABI := armeabi-v7a

ARMv8 AArch64 APP_ABI := arm64-v8a

IA-32 APP_ABI := x86

Intel64 APP_ABI := x86_64

MIPS32 APP_ABI := mips

MIPS64 (r6) APP_ABI := mips64

All supported instruction sets APP_ABI := all

Note: all is available starting from NDKr7.

You can also specify multiple values by placing them on the same line, delimited by spaces. For example:

APP_ABI := armeabi armeabi-v7a x86 mips
