Determine the Type of your Internet Connection

t’s also possible to determine the type of Internet connection currently available.

Device connectivity can be provided by mobile data, WiMAX, Wi-Fi, and ethernet connections. By querying the type of the active network, as shown below, you can alter your refresh rate based on the bandwidth available.

Mobile data costs tend to be significantly higher than Wi-Fi, so in most cases, your app’s update rate should be lower when on mobile connections. Similarly, downloads of significant size should be suspended until you have a Wi-Fi connection.

Having disabled your updates, it’s important that you listen for changes in connectivity in order to resume them once an Internet connection has been established.
