Hello, I'm a beginner in taint analysis. I encountered a problem when using FlowDroid to analyze OkHttp3. I want to find all the network transmission-related methods and their corresponding URLs in an APK. During preprocessing, I instrument the URL strings, wrap them with Date.getConstString, and use <java.util.Date: java.lang.String getConstString(java.lang.String)> as the source and <okhttp3.Call: void enqueue(okhttp3.Callback)> as the sink.

Here is the decompiled result of my APK.

 String temp226 = Date.getConstString("https://xxxxxxxx?q="); String $r102 = z1.d(temp226, $r10, "xxxxx"); Request.Builder $r19 = new Request.Builder(); Request $r20 = $r19.url($r102).build(); OkHttpClient $r21 = b61.d; Call $r222 = $r21.newCall($r20); a61 $r23 = new a61($r17); $r222.enqueue($r23); 

The current issue is that FlowDroid found 0 leaks. What could be the reason? Where does the flow from source to sink break? If I want to find this leak, what should I do approximately? Do you have any suggestions?

Looking forward to your reply. Thank you very much.
