How to Utilize FlowDroid to Track Implicit Data-Flow

[luoyashuo]

Consider the following code snippet:

String encodedQuery = new Uri.Builder().appendQueryParameter("hwid", getHWID(context)).appendQueryParameter("operador", "cfData").appendQueryParameter("content", str).build().getEncodedQuery();
        OutputStream outputStream = httpURLConnection.getOutputStream();
        outputStream.write(encodedQuery.getBytes("UTF-8"));

I have marked the getHWID method as Source, but it does not taint encodedQuery. I am wondering how I could apply FlowDroid to handle this implicit data flow scenario and ensure encodedQuery gets tainted appropriately whenever getHWID is involved. Any detailed instructions or references would be highly appreciated.

Some summaries were missing. The flow should now be found.
