I'm on Android 7.1.1, here's how I setup on my device (OnePlus One) - without the change of manifest (I was targeting API 21 for my app):

In Charles Proxy:

1. Help > SSL Proxying > Install Charles Root Certificate on a Mobile Device or Remote Browser. This steps gives you the proxy IP and port number and also the link to where you should download charles proxy SSL.

On your phone:

2. Wifi Settings > Modify Network > Advanced Options. Set Proxy to Manual and enter the IP and Port number you received from Charles into Proxy hostname and Proxy port respectively.

3. (OPTIONAL) You may or may not be able to access the chls.pro/ssl link provided by Charles earlier. On my device, I was always notified that I had no network connection. I added the charlesproxy.com to the Bypass proxy for field.

4. On your browser, go to the link in step 3 and download whatever certificate necessary (if it doesn't work on Chrome, download Dolphin Browser).You can name your certificate with whatever name.

Back on Charles Proxy:

5. You should get the prompt to either Allow or Deny your phone to use the proxy if your settings is defaulted to prompt you for remote connections.

You can now use Charles on Nougat 7.1.1.
