逆向 APK
常用的工具如下：
1. jd-gui: 查看 jar 包，Java 工具
2. dex-tools: dex 与 jar 包之间的转换工具，以及 dex 和 smali 之间的转换工具；smali/baksmali 支持从 smali 到 dex 之间的转换，dex2jar 可把 dex 转换为 jar
3. apktool: 解包 apk 的工具，解包后可以得到 smali 文件
4. ClassyShark : google 出的转换工具，可直接从 apk 转换成 class 文件，但没有搜索，编辑等功能
一般的逆向步骤如下：
1. apktool 生成 smali 文件
2. 如果对 smali 文件熟悉，可以直接修改 smali 文件
3. 使用 apktool 重新打包

emanonwzy / Makefile
Created March 14, 2016 17:02 — forked from cstratton/Makefile
A Makefile for building adb outside of a full AOSP tools build, motivated by a need to get a security-enabled ADB onto the Raspberry Pi
#ADB tool for the Raspberry Pi and similar environments not supported by the Android SDK.
#based on https://gist.github.com/splhack/958335
#This is a very simple hack for building adb on its own, using a lot of stock Linux libraries (libssl, libcrypt)
#in place of the versions shipped with AOSP, in order to avoid having to pull down a lot of code.
#git clone https://android.googlesource.com/platform/system/core system/core
#The method below does not work with the most recent version (you will see const char* conversion errors
#as a C file has been changed to a CPP one where that is more strict). However, it _can_ be made to work

# Wrapper around sqlite3 & strace that prints the number of bytes read
# and number of read() system calls at the end.
