Enhanced Apktool reverse artifact

Introduction

First of all, I won't talk about the basic use. Here I only talk about two small functions that I have extended on apktool, one is automatic signature and the other is automatic installation.What function can be achieved, that is, after you change the code, it used to be build-sign-install, and then you can test it on the mobile phone.But now you can complete these three steps in just one sentence. It can be said that you can't feel the existence of these two steps at all, but it is very helpful in static analysis of smali

Auto Sign

The premise of automatic signature is to have a configuration file and signature file, put them in the same directory as apktool, keystore can not be in the same directory, but use an absolute path in the configuration file, as shown below

test.keystoreapktoolapktool.jarsign.conf

The test.keystore is the signature file you created. As for how to create it, you can use eclipse or commands to create it, or you can use the existing one

sign.conf is the configuration file, the content is as follows:

jarsigner -keystore test.keystore -storepass 123456 -signedjar %s %s a123456

We can see that there are two %s, they are the real paths that will eventually be replaced with apk, you can install it like this, now we can try to automatically sign, execute the following command

apktool b -si app

Where -si is the option of automatic signature, app-sign.apk will be generated in dist after signing, you can install it manually

Auto Install

When we auto-sign, we want to auto-install

You can add a -ri option, such as the following command

apktool b -si -ri app

You can achieve automatic signing and installation, and you can execute it every time you modify the code. Isn't it very convenient.The code repository is here The generated apktool.jar is under the art folder of the repository, you only need to download these three files

These two commands can be viewed with the help of apktool

usage: apktool b[uild] [options] -f,--force-all Skip changes detection and build allfiles.  -i,--install Install this apk.  -o,--output  The name of apk that gets written. Default is dist/name.apk  -p,--frame-path  Uses framework files located in .  -ri,--reinstall Reinstall this apk.  -si,--sign Sign this apk.

The -si and -ri I added are the two commands mentioned above. -i is also installed, but not covered, so it is not commonly used
