Question

我使用sootclasses-trunk-jar-with-dependencies.jar为具有API 19的Android应用程序构建CallGraph CHA。以下是我的代码。

Options.v().set_include_all(true);

    Options.v().set_app(true);

    soot.Scene.v().loadNecessaryClasses();
    //soot.Scene.v().setEntryPoints(EntryPoints.v().all());

        HashMap opt = new HashMap();
    //opt.put("include-all","true");
    //opt.put("app","true");
    opt.put("enabled","true");
    opt.put("full-resolver","true");
    opt.put("verbose", "false");

    List<SootMethod> entryPoints = getAllEntryMethods();
    logger.info("entry points: "+entryPoints);
    Scene.v().setEntryPoints(entryPoints);

    CHATransformer.v().transform("", opt);
    callGraph = Scene.v().getCallGraph();   

}`

所以当到达CHATransformer.v().transform("", opt);指令时，它给了我以下错误：
