Firt of all we need to create extension function for connectivity.
fun Context.getConnectivity(): NetworkCapabilities? {
val cm = getSystemService(Context.CONNECTIVITY_SERVICE) as ConnectivityManager
return if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
cm.getNetworkCapabilities(cm.activeNetwork)
} else {
TODO("VERSION.SDK_INT < M")
}
}
then we can call extension function that we have made into activity/fragment that will use it.
val connectivity = this.getConnectivity()
after that we can use that to check connectivity before display the data.
if (connectivity != null) {
if (connectivity.hasTransport(NetworkCapabilities.TRANSPORT_WIFI)) {
setupData()
}
if (connectivity.hasTransport(NetworkCapabilities.TRANSPORT_CELLULAR)) {
setupData()
}
} else {
Toast.makeText(this, "No internet connection", Toast.LENGTH_SHORT).show()
}
that’s all.
