            Android Wifi Scanner NOT SHOWING RESULTS IN LISTVIEW

            Asked 2021-Jan-19 at 18:28

            I am coding a wifi scanner to scan available networks and connect to them. My code compiles without an issue and the app runs, BUT the scanned results do not show in the list view. Please help. Even the button click which triggers a toast runs as expected.

            Gradle dependencies add

            "implementation 'pub.devrel:easypermissions:2.0.1'" and compile

            Using the easy permissions library I was able to solve the problem and introduce a more maintainable code.
