Common Problems – Android

Here are some of the common issues people face when working with Android and Charles. Details on how to fix these issues has also been included.


Time Outs

The app or browser keeps timing out

Check if the local IP address of your Mac has changed

If it has changed, it means your device can no longer talk to your Mac. Essentially your iOS device has no internet connection!

Access Denied

My IP address hasn’t changed and I still can’t see traffic from my device on Charles

If you see a message in the bottom left-hand corner of Charles about ‘Denying access ….’, the fix is actually quiet straightforward

Restart Charles. Return to your browser/app and reload the page/screen

Go back to Charles and you should now see a dialog (see next screenshot below) about accepting a connection from you device

Click ‘Allow’

Why did this happen?

This error can occur if you dismiss the dialog (by clicking the red circle) or accidentally click ‘Deny’ button

The dialog message says “If you deny this you will not be asked again for this host address until you restart Charles”.

Managing local IP address

The ‘Access Control Settings’ screen lists the local IP addresses of all devices that can communicate with your instance of Charles

Using PlayStore Apps

I’ve “Enabled SSL Proxying” but I still can’t view the traffic

If you’re device’s is running Android 7 (Nougat) or higher, you can NOT decrypt HTTPS traffic!

There are only way 2 ways of viewing encrypted traffic on Android devices:

  1. Use a device that runs Android 6 or lower
  2. Build your own app
