Android - delete WIFI

[danten]

It does not work, it only shuts down and does not delete saved connection settings.

Delphi-Quellcode:

procedure TfrmApp.RemoveWifiList;
var
  WifiManagerObj: JObject;
  WifiManager: JWifiManager;
  List: JList;
  i: Integer;
  LWifiConf: JWifiConfiguration;
  LSsid: String;
  LNetId: Integer;
begin
  try
  WifiManagerObj := SharedActivityContext.getSystemService(TJContext.JavaClass.WIFI_SERVICE);
  WifiManager := TJWifiManager.Wrap((WifiManagerObj as ILocalObject).GetObjectID);

  List := WifiManager.getConfiguredNetworks;

  for i := 0 to List.size -1 do
  begin

    LWifiConf := TJWifiConfiguration.Wrap( List.get(i) );
    LSsid := JStringToString( LWifiConf.SSID );
    LNetId := LWifiConf.networkId;

    WifiManager.removeNetwork( LNetId );

    WifiManager.disableNetwork(LNetId);

    WifiManager.disconnect;
    WifiManager.saveConfiguration();

  end;

  except
    on E: exception do
    begin
      ShowMessage('Remove: '+E.Message);
    end;
  end;

end;

i have the same Problem. The Result from "removeNetwork" is False.

Developer.Andoird says: "Applications are not allowed to remove networks created by other applications." so my app can not delete everything?

Correct, see

So if we are not allowed to change the Wifi network,
maybe there is any alternative method, which asks the user to change the network ?

I think an app should be able to tell what "preferred" network it should use,
and Google probably put something like special permission dialog in ?

The WiFi settings screen can be invoked from code, so the user may be notified about the preferred network first from your app, and then directed to select it there:

Thanks for the info, would be at least the 2nd best option.
I hoped that I could give a parameter with this intent, but it cannot
