# This script is a wrapper for smali.jar, so you can simply call "smali",
# instead of java -jar smali.jar. It is heavily based on the "dx" script
# from the Android SDK

# Set up prog to be the path of this script, including following symlinks,
# and set up progdir to be the fully-qualified pathname of its directory.
prog="$0"
while [ -h "${prog}" ]; do
    newProg=`/bin/ls -ld "${prog}"`

    newProg=`expr "${newProg}" : ".* -> \(.*\)$"`

# If you want DX to have more memory when executing, uncomment the following
# line and adjust the value accordingly. Use "java -X" for a list of options
# you can pass here.
# 
javaOpts="-Xmx512M"

# Alternatively, this will extract any parameter "-Jxxx" from the command line
# and pass them to Java (instead of to dx). This makes it possible for you to
# add a command-line parameter such as "-JXmx256M" in your ant scripts, for
# example.

PATH=$PATH:`pwd`;
export PATH;
exec java $javaOpts -jar "$jarpath" "$@"

2. download file apktool-2.jar. kemudian rename menjadi apktool.jar

3. pindahkan file "apktool" dan "apktool.jar" ke /usr/local/bin

sudo cp apktool /usr/local/bin

sudo cp apktool.jar /usr/local/bin

4. ubah kedua file tersebut agar bisa di execute

sudo chmod +x /usr/local/bin/apktool

sudo chmod +x /usr/local/bin/apktool.jar

5. coba untuk jalankan

apktool

6. extract file apk

apktool file.apk

7. akan dihasilkan folder yang memuat file code-nya
