[Soot-list] A problem about Multiple dex files

[Christian Maeder]

Hi,

in order to reproduce the problem do

1. download
https://github.com/Sable/soot/wiki/code/androidinstr/AndroidInstrument.java_.txt
as AndroidInstrument.java

2. compile it (under linux)

  javac AndroidInstrument.java -cp soot-trunk.jar

Unfortunately https://soot-build.cs.uni-paderborn.de/nightly/
(referenced from https://sable.github.io/soot/) currently gives "404 Not
Found". My version of sootclasses-trunk-jar-with-dependencies.jar from
Nov. 1st (13956977 Bytes, md5sum f9659fa4a01daecb45181bc2a9f532e7) shows
the "WARNING: Multiple dex files detected" whereas an older
soot.trunk.jar from Aug 14th (13933707 Bytes, md5sum
6580e6b0ae6613da016fb6cb813a8c72) does not.

3. get an apk and a (suitable) platform android.jar. I guess any .apk
will do.

4. run it

  java -cp sootclasses-trunk-jar-with-dependencies.jar:.
AndroidInstrument -android-jars platforms -process-dir test.apk

My output:

Soot started on Thu Nov 09 10:48:12 CET 2017
Using 'platforms/android-4/android.jar' as android.jar
Found dex file 'classes.dex' with 150 classes in '/<...>/test.apk'
WARNING: Multiple dex files detected, only processing 'classes.dex'. Use
'-process-multiple-dex' option to process them all.

If I add the option -process-multiple-dex the warning is gone. Still
only a single classes.dex file is reported.

Cheers Christian
