https://stackoverflow.com/questions/30001674/gson-deserialize-null-pointer-in-released-apk in release mode proguard change props names and then final Results results = new Gson().fromJson(result, Results.class); returns null value. Solved problem for release mode scan -- issue was due gson.fromJson with minified/obfuscated class model
