Save networks and Passpoint configurations

On Android 11 (SDK level 30) and higher, apps can use the android.provider.Settings.ACTION_WIFI_ADD_NETWORKS intent to guide the user through adding one or more new saved networks or Passpoint configurations. The API also works as-is to modify existing saved configurations.

To save a network or Passpoint configuration, do the following:

Create an ACTION_WIFI_ADD_NETWORKS intent.
Create one or more configurations using WifiNetworkSuggestion.Builder. Note that even though you use a WifiNetworkSuggestion, this Intent API is not related to the Suggestion API.
Create a parcelable array list of the configurations and attach it to the intent with the EXTRA_WIFI_NETWORK_LIST extra.
Execute Activity.startActivityForResult(), passing in the intent.
Listen for the result using the Activity.onActivityResult() callback.

The resultCode can be one of the following:
- Activity.RESULT_OK: indicating that the user accepted the proposed networks and saved them.
- Activity.RESULT_CANCELED: indicating that the user rejected the proposed networks.
If the resultCode is RESULT_OK, then the data Intent contains the EXTRA_WIFI_NETWORK_RESULT_LIST extra, which contains an array of result codes indicating whether individual configurations were saved successfully. The possible result codes are:
- ADD_WIFI_RESULT_SUCCESS: configuration added or successfully updated.
- ADD_WIFI_RESULT_ADD_OR_UPDATE_FAILED: failure when trying to add configuration, such as due to a badly formed configuration.
- ADD_WIFI_RESULT_ALREADY_EXISTS: the requested configuration already existed so no action was necessary.
If the request is successful, the platform triggers a connection to one of the newly saved networks.

Code sample

The following code sample shows how to save a network or Passpoint configuration.

class MainActivity : AppCompatActivity() {
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        ...
    }

    fun startOperation() {
        val suggestions = ArrayList<WifiNetworkSuggestion>()

        // WPA2 configuration
        suggestions.add(
                WifiNetworkSuggestion.Builder()
                        .setSsid("test111111")
                        .setWpa2Passphrase("test123456")
                        .build()
        )

        // Open configuration
        suggestions.add(
                WifiNetworkSuggestion.Builder()
                        .setSsid("test222222")
                        .build()
        )

        // Passpoint configuration
        val config = PasspointConfiguration()
        config.credential = Credential().apply {
            realm = "realm.example.com"
            simCredential = Credential.SimCredential().apply {
                eapType = 18
                imsi = "123456*"
            }
        }
        config.homeSp = HomeSp().apply {
            fqdn = "test1.example.com"
            friendlyName = "Some Friendly Name"
        }
        suggestions.add(
                WifiNetworkSuggestion.Builder()
                        .setPasspointConfig(config)
                        .build())

        // Create intent
        val bundle = Bundle()
        bundle.putParcelableArrayList(EXTRA_WIFI_NETWORK_LIST, suggestions)
        val intent = Intent(ACTION_WIFI_ADD_NETWORKS)
        intent.putExtras(bundle)

        // Launch intent
        startActivityForResult(intent, 0)
    }

    override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
        super.onActivityResult(requestCode, resultCode, data)
        if(resultCode == RESULT_OK) {
            // user agreed to save configurations: still need to check individual results
            if (data != null && data.hasExtra(EXTRA_WIFI_NETWORK_RESULT_LIST)) {
                for (code in data.getIntegerArrayListExtra(EXTRA_WIFI_NETWORK_RESULT_LIST)) {
                    when (code) {
                        ADD_WIFI_RESULT_SUCCESS ->
                            ... // Configuration saved or modified
                        ADD_WIFI_RESULT_ADD_OR_UPDATE_FAILED ->
                            ... // Something went wrong - invalid configuration
                        ADD_WIFI_RESULT_ALREADY_EXISTS ->
                            ... // Configuration existed (as-is) on device, nothing changed
                        else ->
                            ... // Other errors
                    }
                }
            }
        } else {
            // User refused to save configurations
        }
    }
}
