Hi Jason,
Great that it works now. I CC’ed the list so that the others also know that
the problem is solved and we don’t need to look further.
In general, I do not recommend mixing Options.v() and command-line options
passed to the main method. I’d always chose one or the other, but not mix
them.
Best regards,
Steven

Hi Jason,
Your option list is a bit weird. Please set “-src-prec apk”. The main
activity thing is commented out, but should not be there anyway.
Furthermore, I would not use the “-pp” option with Android since your Java
classpath contains the JRE JARs and not the ones from Android.
Best regards,
Steven

Dear Steven：
Thanks for your replay firstly.The following code is my soot
configuration:
main:
G.reset();
Options.v().set_src_prec(Options.src_prec_apk);
List<String> argsList = new ArrayList<String>();
argsList.addAll(Arrays.asList(new String[] { "-w",//
// "MainActivity",//
main-class
// "MainActivity",// argument
classes
"-android-jars",//
AndroidPlatform,//
"-process-dir",//
AkpPath,//
"-pp",//
"-allow-phantom-refs", "-f",
"n",//
}));
Scene.v().addBasicClass("java.io.PrintStream",SootClass.SIGNATURES);
Scene.v().addBasicClass("java.lang.System",SootClass.SIGNATURES);
String[] soot_args = argsList.toArray(new
String[0]);
Pack pack1=PackManager.v().getPack("wjtp");
pack1.add(new Transform("wjtp.myTrans", new
CompTransfor()));
soot.Main.main(soot_args);
The CompTransfor class:
public class CompTransfor extends soot.SceneTransformer {
@Override
protected void internalTransform(String arg0, Map<String,
String> arg1) {
List<SootClass> applicationClass = new ArrayList<SootClass>();
Iterator<SootClass> iterator =
Scene.v().getApplicationClasses().iterator();
while (iterator.hasNext()) {
SootClass temp = iterator.next();
String classname = temp.getName();
if
(!classname.startsWith("android")&&!classname.startsWith("java"))
applicationClass.add(temp);
}
for (int i = 0; i < applicationClass.size(); i++) {
SootClass sc = applicationClass.get(i);
List<SootMethod> methodList = sc.getMethods();
for (SootMethod sm : methodList) {
Body body = sm.retrieveActiveBody();
UnitGraph g = new
ExceptionalUnitGraph(body);
..............
}
}
}
The is the kernel part of my code to get the unitGraph of the Apk file. Do
it make a sense?

Hi Jason,
Please send the code with which you use Soot and the options with which you
configure Soot. Since you are analyzing an APK file, Soot should not be
using Coffi at all if I’m not mistaken.

Steven
