AndroidMagic(使用LibMagic识别文件类型)

An android project to query file info with LibMagic

Introduction

The file command is "a file type guesser", that is, a command-line tool that tells you in words what kind of data a file contains. Unlike most GUI systems, command-line UNIX systems - with this program leading the charge - don't rely on filename extentions to tell you the type of a file, but look at the file's actual contents. This is, of course, more reliable, but requires a bit of I/O.

Details

This project is for me to learn Java, NDK, and for fun.

• learn how to build ndk and sign apk with android gradle-experimental
• source code is from open source implementation of the file command
• libmagic is "a file type guesser", that tells you in words what kind of data a file contains

学习记录

• 使用libmagic，我们不用看文件的后缀，就可以识别出常用文件类型
• 移植LibMagic到安卓平台上, 使文件类型的识别不仅通过扩展名
• 使用cmake编译NDK
• Java与本地代码之间内存拷贝GetByteArrayRegion
• butterknife 以及 rxjava的使用
