Internet availability

An Android library that allows for internet availability observation.

How it works

  • Internet capable networks are observed and a URL is pinged through them. Each time a network change happens pings are made using currently enabled networks.
  • When pinging the precedence is given to non-metered networks, so no metered networks get pinged in case internet availability is detected on a non-metered network.
  • Besides pings that happen on each network change, additional pings can happen in given intervals to continuously keep checking for internet availability.
  • Observation and pinging start on the first availability collector and stop 5s after the last collector completes.

How to use

Instantiate an Internet instance and collect from its availability flow in a lifecycle-aware manner.

val internet = Internet.getInstance(
    scope, // Application CoroutineScope
    pingUrl = "", // A url to be pinged
    pingTimeoutMillis = 2_000, // Ping timeout
    pingRetryTimes = 0, // How many times to retry pinging
    pingRetryIntervalMillis= 0, // Delay between each ping retry
    pingOnNonMeteredNetworks = true, // Should pinging happen on non-metered networks
    nonMeteredNetworksPingIntervalMillis= 10_000, // Delay between each ping on non-metered networks
    pingOnMeteredNetworks = true, // Should pinging happen on metered networks
    meteredNetworksPingIntervalMillis = 10_000, // Delay between each ping on metered networks
    context: Context // Application Context

// For Jetpack Compose
val hasInternet by internet.availability.collectAsStateWhenStarted() // Check the sample app

// Alternatively for Jetpack Compose and for Android Views
internet.availability.collectWhenStarted(scope, onEach) // Check the sample app
