问题
I am developing an app using App Inventor. It includes the need for a user to press a button - to save a location when they are at the location. But every time this is not practical. So I want to implement a method in my App Inventor app which will: -Open Google Maps -Let the user select any point on the map with no additional info. -After choosing, return to the app and return latitude, longitude values for the location that is selected. This is really important for me, help will be appreciated. Thanks!
