Cannot get the inner class/implicit calls CFG from Flowdroid

[99zikke]

I have tried to get the CFG of the codes below. But Flowdroid can only get the CFG of outer class.

public class MainActivity extends AppCompatActivity {
    ...

    public class MyHandler extends Handler {
        ...
        

        public void handleMessage(Message msg) {
                         ...something I want to detect
                  }
        }
}

My codes used to get the CGF are as below

SetupApplication analyzer = new SetupApplication
                ("D:\\android_sdk\\android-sdk_r24.4.1-windows\\platforms",
                        "C:\\Users\\xxx.apk");

        analyzer.constructCallgraph();
        for(int i = 1; i > 19; i ++){
            int a  = 1;
        }
        // Iterate over the callgraph
        for(Iterator<Edge> edgeIt = Scene.v().getCallGraph().iterator(); edgeIt.hasNext(); )
        {
            Edge edge = edgeIt.next();

            SootMethod smSrc = edge.src();
            Unit uSrc = edge.srcStmt();
            SootMethod smDest = edge.tgt();

            System.out.println("Edge from " + uSrc + " in " + smSrc + " to " + smDest);
        }

I can find the jimple of

public void handleMessage(Message msg) {
                        ...something I want to detect
                 }

but I couldn't get them in the CFG. What should I do?
I'd be really grateful for your answer!

I can find

public class MainActivity extends AppCompatActivity {
    ...

    public class MyHandler extends Handler {
        ...

in CFG, while I cannot find

public void handleMessage(Message msg) {
                        ...something I want to detect
                 }

in CFG.

I have set the

analyzer.getConfig().setEnableImplicitFlows(true);
analyzer.constructCallgraph();

but I still didn't find what I want, what should I do ?

老哥，你这不是获取的函数调用图么，为啥上面说是控制流图（CFG）？
貌似函数调用图获取的不够全，涉及到线程貌似都不大行
