I want to investigate a apk and I have make it to com.a.app_classes-dex2jar.jar.
However, when I drag and drop it into jd-gui.exe, I find some lines of the obfuscated code cannot be jumped to and don't what the line actually done.
b b = new b();
f f = new f();
but then the b and f is not further used inside the method. I just want to know why I move my mouse on class b has no hyperlink for me to jump into detail of class b, and I have a quick look into the whole .class file and does not see any custom class b is written. What are the lines doing?
