Why I can't see all HTTP requests from Charles? (Android)

Question

I try to intercept requests from a game one Android. I used Charles web debugging proxy and Proxydroid for that. But the problem is I can't see all HTTP requests, I'm obliged to use Wireshark...

Here's an example of requests I can see with Wireshark but not with Charles:
