apktool是apk反编译的核心，其他GUI工具内部都是用apktool来执行反编译任务。

apktool.bat内容如下:
1 2 3 4 5 @echo off if "%PATH_BASE%" == "" set PATH_BASE=%PATH% set PATH=%CD%;%PATH_BASE%; chcp 65001 2>nul >nul java -jar -Duser.language=en -Dfile.encoding=UTF8 "%~dp0\apktool.jar" %*
反编译 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 $ java -jar apktool.jar d test.apk 或者 $ ./apktool.bat d test.apk I: Using Apktool 2.3.0 on test.apk I: Loading resource table... I: Decoding AndroidManifest.xml with resources... I: Loading resource table from file: 1.apk I: Regular manifest package... I: Decoding file-resources... I: Decoding values */* XMLs... I: Baksmaling classes.dex... I: Copying assets and libs... I: Copying unknown files... I: Copying original files... $ ./apktool.bat b test I: Using Apktool 2.3.0 on test I: Checking whether sources has changed... I: Smaling smali folder into classes.dex... I: Checking whether resources has changed... I: Building resources... I: Building apk file... I: Copying unknown files/dir...
反编译结果在apk文件同名目录下
修改内容
assets
res 可以修改资源
smali 可以修改源码
重新打包 1 $ ./apktool.bat b ./test -o ./test_unsigned.apk
此时重新打包为apk的文件是未签名的，需要用jdk的jarsigner工具重新签名
签名 1 2 3 4 $ jarsigner -verbose -keystore /tmp/test.jks -signedjar test-signed.apk test_unsigned.apk key0 input key password >> ******
