How to Convert any Android apk file into Soot's Intermediate Representation Jimple
Lets look at command to convert any android apk file into Jimple.
For conversion, you need to:
> Download any .apk file
> Download android sdk from android developer site or download android jars
> Download Soot's nightly build version from Soot- Github
Before applied command, you need to know right path for android sdk -platforms directory, .apk file located directory and nightly build version of soot at right directory
Set CLASSPATH of Soot.jar or go to the directory that contains Soot.jar file then type following Command:
> java -Xmx2g -jar soot-trunk.jar soot.Main -w -allow-phantom-refs -android-jars "D:\sdk\platform" -src-prec apk -f jimple -process-dir "C:\apkpath\example.apk"
If you have already set CLASSPATH for jar then type following
>java -Xmx2g soot.Main -w -allow-phantom-refs -android-jars "D:\sdk\platform" -src-prec apk -f jimple -process-dir "C:\apkpath\example.apk"
Details: -Xmx2g it represents memory of 2GB which is normally sufficient for any apk process.
-jar can be replaced by -cp which means CLASSPATH or it represent command prompt's current directory.
-W stands for writing
-allow-phantom-refs creates phantom classes for missing or unprocessed classes
-android-jars leads to path for android sdk or jars to process apks
-src-prec represents the file format you are trying to process
-f jimple or -f J is responsible for converting all the classes from apk into jimple files
-process-dir shows the path for processing directory or apk located directory
Your post was really helpful and worked. In link "https://github.com/Sable/soot/wiki/Instrumenting-Android-Apps-with-Soot", Eric mention doing it with Java Program. May you please help how can we run that Java program(AndroidInstrument.java) to Instrument apk.
ReplyDeleteI'm looking for the same thing doing it through java program .
ReplyDeletecould you help in this?
OMG THis actually worked. Is there actually an official documentation detailing how to do this and explaining it? The main soot wiki is really confusing.
ReplyDeleteThank you!
