I'm using MLWifi V3.03 and B4A V8.00. My target phones are all rather old (Android V4 and V5) because are all specially ruggedised and instrinsically safe devices. I want to use the removeWifiAP command from MLWifi, which is listed in MLWifi.xml, but B4A highlights it in red and says "Undeclared Variable 'RemoveWifiApp' is used before it is assigned any value". The library works fine (aside from a few features not supported in Android V4).
