If you are facing issue using Charles on Device tar-getting above 7.0 in Android, follow these steps, as detailed in the Charles Proxy documentation

1. Add following line

   android:networkSecurityConfig="@xml/network_security_config"> 
   

   to your manifest file in Application Tag.

2. Create a xml folder with a file named network_security_config and paste following code in it.

<?xml version="1.0" encoding="utf-8"?>
<network-security-config>
    <base-config>
        <trust-anchors>
            <certificates src="system" />
        </trust-anchors>
    </base-config>
    <debug-overrides>
        <trust-anchors>
            <certificates src="user" />
        </trust-anchors>
    </debug-overrides>
</network-security-config>

Note: Do not commit above to your branch if you have only single build flavours.
