You may customise how and when your phone connects to Wi-Fi to suit your needs. When you switch on Wi-Fi, your phone automatically connects to neighbouring Wi-Fi networks that you've previously connected to. You may also set your phone to switch on Wi-Fi when it gets close to a stored network.
Important: Some of these procedures are only applicable to Android versions 10 and higher. Learn how to figure out what Android version you have.
Connect & turn on
Swipe down from the top of the screen.
Wi-Fi should be touched and held.
Use Wi-Fi is turned on.
Select a network from the list. A Lock is used on networks that require a password.
The network is "Saved" when you connect. When your phone is close by and Wi-Fi is turned on, it joins to this network automatically.
Apart from online communication, Android's wireless APIs also allow communication with other devices on the same local network, as well as devices that are not connected to a network but are physically close. NSD expands on this by allowing an application to search for a nearby device that is running services with which it may interact. Integrating this capability into your programme allows you to offer a variety of services, such as playing games with users in the same room, extracting photos from a networked NSD-enabled webcam, and remotely login into other devices on the same network.
This class explains how to use the essential APIs in your application to locate and connect to other devices. The NSD API is used to find accessible services, while the Wi-Fi Peer-to-Peer (P2P) API is used to establish peer-to-peer wireless connections.. This lesson also shows how to use NSD and Wi-Fi P2P in conjunction to identify and connect to a device's services even when neither device is connected to a network.
Consider utilising the Nearby Connections API for your Android application if you need a higher-level API to transport data consistently and securely between devices using a mix of Wi-Fi and Bluetooth.
