7-Zip 主要特征
使用了 LZMA 与 LZMA2 算法的 7z 格式 拥有极高的压缩比
支持格式：
压缩 / 解压缩：7z、XZ、BZIP2、GZIP、TAR、ZIP 以及 WIM
仅解压缩：AR、ARJ、CAB、CHM、CPIO、CramFS、DMG、EXT、FAT、GPT、HFS、IHEX、ISO、LZH、LZMA、MBR、MSI、NSIS、NTFS、QCOW2、RAR、RPM、SquashFS、UDF、UEFI、VDI、VHD、VMDK、WIM、XAR 以及 Z
与 ZIP 及 GZIP 格式相比，7-Zip 能提供比使用 PKZip 及 WinZip 高 2-10% 的压缩比
为 7z 与 ZIP 提供更完善的 AES-256 加密算法
7z 格式支持创建自释放压缩包
Windows 资源管理器集成

支持 87 种语言
7-Zip 适用于 Windows 10 / 8 / 7 / Vista / XP / 2016 / 2012 / 2008 / 2003 / 2000。
p7zip - Linux/Posix 平台的命令行移植版本。
在 Source Forge 的 7-Zip 页面（英文）中您可以找到相关的论坛、错误汇报及系统需求。

下载完解压 因为版本是 p7zip_16.02_src_all.tar.bz2 比较老旧了，使用NDK环境16
cd 到解压后的目录****/p7zip_16.02/CPP/ANDROID/7zr

# Needed since ANDROID 5, these programs run on android-16 (Android 4.1+)
#这两个语句的作用是。具体而言，第一条语句；第二条语句。
#将-fPIE和-fPIC编译选项添加到原有的编译选项中
LOCAL_CFLAGS += -fPIE #将-fPIE选项添加到编译选项中，用于生成位置无关可执行文件
LOCAL_CFLAGS += -fPIC #将-fPIC选项添加到编译选项中，用于生成位置无关代码的共享库
LOCAL_LDFLAGS += -fPIE -pie
#使用+=将-fPIE和-pie选项添加到LOCAL_LDFLAGS变量中。
#-fPIE选项用于生成位置无关可执行文件，这样可以使得可执行文件更加安全，因为攻击者不能直接跳转到数据段中的代码。PIE的全称是Position Independent Executable，即位置无关可执行文件。
#-pie选项用于生成可重定位的位置无关可执行文件，这种文件可以在被加载到内存中时进行重定位，因此可以使得程序的地址空间更加随机，增加程序的安全性。
#这两个选项结合起来使用，能够使得生成的可执行文件更加安全。使用这两个选项的前提是，必须使用支持这些选项的链接器。
#总的来说，这条语句的作用是将-fPIE和-pie选项添加到链接器的选项中，用于生成位置无关可执行文件，并使得程序的地址空间更加随机，提高程序的安全性。
include $(BUILD_SHARED_LIBRARY) #修改成动态库
# include $(BUILD_EXECUTABLE)
修改Application.mk 其实可以只编译armeabi的 因为下面说了 一样快
# The ARMv7 is significanly faster due to the use of the hardware FPU
APP_ABI := armeabi-v7a x86
# p7zip armeabi and armeabi-v7a run at the same speed (p7zip does not use FPU)
# APP_ABI := armeabi armeabi-v7a
APP_PLATFORM := android-16
