Setting Up Android Proxy
Step 1: Open Android’s Settings app and tap “Wi-Fi” to view a list of Wi-Fi networks.
Step 2: Long-press the name of the Wi-Fi network you want to change the proxy settings for. Tap “Modify Network” when a menu appears.
(If you haven’t already connected to the Wi-Fi network, you’ll need to connect to the Wi-Fi network and enter its passphrase before you can access the “Modify Network” options.)
Step 3: Expand the “Advanced options” section on this screen. Tap the “Proxy” option and select
Step 4: When you select “Manual”, you can manually enter the proxy server’s details. Enter the address of the proxy server in the “Proxy hostname” box. Then enter the proxy's port number, and tick the box for "authenticate server" and enter the username and password of your proxy.
Step 5: Tap “Save” to save your settings when you’re done.
