【Android 安装包优化】使用 lib7zr.so 动态库处理压缩文件 ( 修改 7zr 交叉编译脚本 Android.mk | 交叉编译 lib7zr.so 动态库 )【Android 安装包优化】使用 lib7zr.so 动态库处理压缩文件 ( 拷贝 lib7zr.so 动态库到 Android Studio 工程 | 配置 build.gradle 构建脚本 )【Android 安装包优化】使用 lib7zr.so 动态库处理压缩文件 ( 拷贝 lib7zr.so 动态库头文件到 Android 工程中 | 配置 CMakeLists.txt 构建脚本 )【Android 安装包优化】使用 lib7zr.so 动态库处理压缩文件 ( 测试 lib7zr.so 动态库调用 )【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 ;
# FIXMEdebug:cd jni ; ndk-build NDK_DEBUG=1adb push ./libs/armeabi/7zr /data/app/adb push ./libs/armeabi/gdbserver /data/app/adb shell chmod 777 /data/app/7zradb shell chmod 777 /data/app/gdbserveradb forward tcp:1234: tcp:1234adb 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_64APP_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 :
# # build 7zr for armeabi and armeabi-v7a CPU## WARNING : file generated by generate.py#LOCAL_PATH := $(call my-dir)include $(CLEAR_VARS)# 编译模块 # 如果编译可执行文件, 编译结果是 7zr# 如果编译动态库, 编译结果是 lib7zr.so#

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
进入 D:\develop\7zip\p7zip_16.02\CPP\ANDROID\7zr\jni 目录 , 执行如下命令 :
D:\001_Programs\001_Android\002_Sdk\Sdk\ndk\16.1.4479499\ndk-build.cmd
编译要很长时间 , 输出如下结果后 ,
最终在 D:\develop\7zip\p7zip_16.02\CPP\ANDROID\7zr\libs\armeabi-v7a 目录下 , 生成了可执行的 7zr 程序 ;
总共生成了 444 种 CPU 架构的 静态库 ; 注意静态库的生成位置 D:\develop\7zip\p7zip_16.02\CPP\ANDROID\7zr\obj\local 目录下 ;
静态库编译出来体积比较大 , 此处 lib7zr.a 静态库有 9.15 MB , 静态库编译时将所有的符号都编译在其中 , 因此比动态库大十几倍 ;
动态库编译后体积较小 , 方便分发 , 常用的第三方服务 , 以及开源代码都使用动态库进行分发 ;
编译过程中其它生成文件如下图 :
编译时遇到的错误 :
【错误记录】Android Studio 导入外部 so 动态库报错 ( java.lang.UnsatisfiedLinkError | 指定 APK 打包动态库的 CPU 架构 )【错误记录】p7zip 交叉编译 Android 版本 NDK 报错 ( error: case value evaluates to -2 , which cannot be narrowed )
四、Android Studio 导入 lib7zr.a 静态库
主要是修改 CMakeLists.txt 构建脚本 , 其它位置不需要修改 ;
# 指定 CMake 最低版本cmake_minimum_required(VERSION 3.4.1)# 设置函数库编译add_library( # 参数 1 : 设置生成的动态库名称native-lib# 参数 2 : 设置生成的函数库类型 : ① 静态库 STATIC ② 动态库 SHAREDSHARED# 参数 3 : 配置要编译的源文件../cpp/native-lib.cpp)# 打印日志信息# ${ANDROID_ABI} 的作用是获取当前的 CPU 指令集架构# 当本次编译 armeabi-v7a CPU 架构时 , ${ANDROID_ABI} 值为 armeabi-v7a# 当本次编译 x86 CPU 架构时 , ${ANDROID_ABI} 值为 x86message("CMAKE_SOURCE_DIR : ${CMAKE_SOURCE_DIR}, ANDROID_ABI : ${ANDROID_ABI}")# 到预设的目录查找 log 库 , 将找到的路径赋值给 log-lib# 这个路径是 NDK 的 ndk-bundle\platforms\android-29\arch-arm\usr\lib\liblog.so# 不同的 Android 版本号 和 CPU 架构 需要到对应的目录中查找 , 此处是 29 版本 32 位 ARM 架构的日志库## 可以不配置 :# 可以不进行该配置, 直接在后面的 target_link_libraries 中链接 log 也不会出错find_library(log-liblog)# 打印日志库位置message(${log-lib})# 引入静态库 ( 推荐 ) :# ① 参数 1 ( add ) : 设置引入的静态库名称# ② 参数 2 ( SHARED ) : 设置引入的函数库类型 : ① 静态库 STATIC ② 动态库 SHARED# ③ 参数 3 ( IMPORTED ) : 表示引入第三方静态库 , 导入静态库 , 相当于预编译静态库#后续还需要设置导入路径 , 配合该配置使用add_library(# 设置引入的静态库名称7zr# 设置引入的函数库类型为静态库STATIC# 表示引入第三方静态库IMPORTED)# 设置上述静态库的导入路径# 设置目标属性参数 :# ① 参数 1 ( add ) : 要设置哪个函数库的属性# ② 参数 2 ( PROPERTIES ) : 设置目标属性# ③ 参数 3 ( IMPORTED_LOCATION ) : 设置导入路径# ④ 参数 4 : 配置静态库的文件路径set_target_properties(# 设置目标7zr# 设置属性PROPERTIES# 导入路径IMPORTED_LOCATION# ${CMAKE_SOURCE_DIR} 是本 CMakeList.txt 构建脚本的路径 , 是 CMake 工具内置的变量# Android CMake 也内置了一些变量 , 如 ANDROID_ABI${CMAKE_SOURCE_DIR}/${ANDROID_ABI}/lib7zr.a)# 打印静态库位置message("静态库位置 : ${CMAKE_SOURCE_DIR}/${ANDROID_ABI}/lib7zr.a")# 引入动态库 (不推荐) : 使用下面的方式引入动态库会出现于 Android.mk 配置一样的问题 , 6.0 以上的 Android 系统在运行时出现找不到路径的问题#add_library(add SHARED IMPORTED)# 设置函数库的导入路径#set_target_properties(add PROPERTIES IMPORTED_LOCATION ${CMAKE_SOURCE_DIR}/../jniLibs/armeabi-v7a/libadd.so)# 引入动态库 (推荐) :# 设置变量# CMAKE_CXX_FLAGS 表示会将 C++ 的参数传给编译器# CMAKE_C_FLAGS 表示会将 C 参数传给编译器# 参数设置 : 传递 CMAKE_CXX_FLAGS C+= 参数给编译器时 , 在 该参数后面指定库的路径# CMAKE_SOURCE_DIR 指的是当前的文件地址# -L 参数指定动态库的查找路径#set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -L${CMAKE_SOURCE_DIR}/../jniLibs/${ANDROID_ABI}")# 设置头文件查找路径include_directories(../cpp/lib7zr/CPP/7zip/Archive../cpp/lib7zr/CPP/7zip/Archive/7z../cpp/lib7zr/CPP/7zip/Archive/BZip2../cpp/lib7zr/CPP/7zip/Archive/Common../cpp/lib7zr/CPP/7zip/Archive/GZip../cpp/lib7zr/CPP/7zip/Archive/Cab../cpp/lib7zr/CPP/7zip/Archive/Lzma../cpp/lib7zr/CPP/7zip/Archive/Tar../cpp/lib7zr/CPP/7zip/Archive/Zip../cpp/lib7zr/CPP/7zip/Archive/Split../cpp/lib7zr/CPP/7zip/Archive/Z../cpp/lib7zr/CPP/7zip/Compress../cpp/lib7zr/CPP/7zip/Crypto../cpp/lib7zr/CPP/7zip/UI/Console../cpp/lib7zr/CPP/7zip/UI/Common../cpp/lib7zr/CPP/Windows../cpp/lib7zr/CPP/Common../cpp/lib7zr/CPP/7zip/Common../cpp/lib7zr/C../cpp/lib7zr/CPP/myWindows../cpp/lib7zr/CPP../cpp/lib7zr/CPP/include_windows)# 链接函数库# 参数 1 : 本构建脚本要生成的动态库目标# 参数 2 ~ ... : 后面是之前预编译的动态库或静态库 , 或引入的动态库target_link_libraries(native-lib# 表示 编译 native-lib 模块, 要链接 lib7zr.so 模块7zr${log-lib})
