Is it possible to add a network configuration on Android Q?

Question

Background

I\'ve noticed that in WifiManager class there is a function called addNetwork, that might be useful if I want to restore or save networks information (n

Looks like they've added support in Android 11(API 30) for adding network configuration that persists outside of the application scope and is saved as a system network configuration just like it was done with the deprecated WiFiManager method addNetwork. All you need to do is to use ACTION_WIFI_ADD_NETWORKS to show a system dialog that asks a user if he wants to proceed with adding a new Wifi suggestion to the system. This is how we start that dialog:

// used imports
import android.provider.Settings.ACTION_WIFI_ADD_NETWORKS
import android.provider.Settings.EXTRA_WIFI_NETWORK_LIST
import android.app.Activity
import android.content.Intent
import android.net.wifi.WifiNetworkSuggestion





// show system dialog for adding new network configuration
    val wifiSuggestionBuilder = WifiNetworkSuggestion.Builder()
                .setSsid("network SSID")
                .build()

    val suggestionsList = arraylistOf(wifiSuggestionBuilder)
    val intent = new Intent(ACTION_WIFI_ADD_NETWORKS)
    intent.putParcelableArrayListExtra(EXTRA_WIFI_NETWORK_LIST, suggestionsList);
    activity.startActivityForResult(intent, 1000)

The dialog looks like this:

And then we just need to handle a result in onActivityResult method like this:

override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
    if (requestCode == 1000) {
        if (resultCode == Activity.RESULT_OK) {
            // network succesfully added - User pressed Save
        } else if (resultCode == Activity.RESULT_CANCELED) {
            // failed attempt of adding network to system - User pressed Cancel
        }
    }
}

But as I've tested this code on Android devices that have older Android versions(lower then API30) installed I've got a crash every time I want it to show that dialog for adding a new network configuration. This is the crash:

java.lang.RuntimeException: Unable to start activity: android.content.ActivityNotFoundException: No Activity found to handle Intent { act=android.settings.WIFI_ADD_NETWORKS (has extras) }

Looks like the new way is not back-supported out of the box. So, for API30 we can use a new Intent action, for API 28 and below we can still use the old way of adding Networks, but for API29 we have some kind of gray area where I was not able to find a good solution yet. If anyone has an idea what else to do please share it with me. ;)
