【Android 安装包优化】使用 lib7zr.so 动态库处理压缩文件 ( jni 中 main 函数声明 | 命令行处理 | jni 调用 lib7zr.so 函数库处理压缩文件完整代码 )
在之前的一系列博客中使用 lib7zr.so 动态库处理压缩文件 , 本篇博客中使用静态库处理压缩文件 , 仅做参考 ;
一、修改 7zr 交叉编译脚本 Android.mk
之前的博客 【Android 安装包优化】p7zip 源码交叉编译 Android 平台可执行程序 ( 下载 p7zip 源码 | 交叉编译 Android 中使用 7z 可执行程序 ) 中 , 下载并编译了 p7zip 开源项目源码 , 交叉编译出了可以在 Android 平台执行的可执行文件 ;
D:\develop\7zip\p7zip_16.02\CPP\ANDROID\7zr 目录下是 7zr 项目的构建脚本 Android.mk 和 Application.mk , 主要使用该构建脚本交叉编译出
可执行文件 7zr
静态库 lib7zr.a ;
进入 7zr 目录下 , 有一个 jni 目录 和 makefile 文件 ,
jni 目录中是 Android.mk 和 Application.mk 两个构建脚本 , 可以使用 ndk-build 进行编译 ;
打开该 makefile 文件 , 该文件最后几行代码给出了相关操作方法 ;
# FIXME debug: cd jni ; ndk-build NDK_DEBUG=1 adb push ./libs/armeabi/7zr /data/app/ adb push ./libs/armeabi/gdbserver /data/app/ adb shell chmod 777 /data/app/7zr adb shell chmod 777 /data/app/gdbserver adb forward tcp:1234: tcp:1234 adb shell /data/app/gdbserver :1234 /data/app/7zr
进入 D:\develop\7zip\p7zip_16.02\CPP\ANDROID\7zr\jni 目录 , 执行 ndk-build 命令 , 进行交叉编译 ;
修改 Application.mk 构建脚本 :
APP_ABI := armeabi-v7a arm64-v8a x86 x86_64 APP_PLATFORM := android-8
注释可执行文件的编译选项 : -fPIE 指的是生成与地址无关的可执行文件 , 该选项只能应用于可执行文件 , 不能用于静态库编译 ;
# Needed since ANDROID 5, these programs run on android-16 (Android 4.1+) # -fPIE 指的是生成与地址无关的可执行文件 , 该选项只能应用于可执行文件 , # 不能用于动态库编译 # 如果编译动态库 , 需要注释掉下面两个配置 # 如果编译静态库 , 需要注释掉下面两个配置 # 如果编译可执行文件 , 可以保留下面两个配置 #LOCAL_CFLAGS += -fPIE #LOCAL_LDFLAGS += -fPIE -pie
设置 Android.mk 构建脚本的编译结果 :
include $(BUILD_STATIC_LIBRARY)include $(BUILD_EXECUTABLE) 配置表示生成可执行文件 ;
include $(BUILD_SHARED_LIBRARY) 配置表示生成 .so 动态库 ;
include $(BUILD_STATIC_LIBRARY) 配置表示生成 .a 静态库 ;
二、完整的 7zr 交叉编译脚本 Android.mk
修改完成的构建脚本 :

# 如果编译静态库, 编译结果是 lib7zr.a LOCAL_MODULE := 7zr # 设置编译器参数 # -I 指定头文件引入目录 , 会引入后面目录中所有的 .h 头文件 LOCAL_CFLAGS := -DANDROID_NDK -fexceptions \ -DNDEBUG -D_REENTRANT -DENV_UNIX \ -DBREAK_HANDLER -D_NO_CRYPTO

三、交叉编译 lib7zr.a 静态库
使用最低版本的 NDK 进行编译 , 使用高版本 NDK 编译各种报错 ;
使用 16.1.4479499 版本的 NDK 进行编译 :
>D:\001_Programs\001_Android\002_Sdk\Sdk\ndk\16.1.4479499\ndk-build.cmd
