Dear Steven:
Thanks for reply. Actually，I had set the “-src-prec apk”set in the second line and I remove the "--pp" options right now. while it still didn't work.Do it have any other wrong configuration ?
The configuration is following:(The AndroidPlatform and AkpPath is a String type which i set at the beginning of code);
G.reset();
Options.v().set_src_prec(Options.src_prec_apk);
List<String> argsList = new ArrayList<String>();
argsList.addAll(Arrays.asList(new String[] { "-w", "-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);
Thanks&Regards,
Jason

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", "-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.
Best regards,
Steven
