I am working on an app that makes sure all the members of a certain group are present in the same location as the group leader..
so the idea is that in the app there are groups that consist of members and a group leader, when the leader clicks on a certain button the app checks if each member in the group is present with the leader. Here is how I thought of doing it, but don't know the tools I'll need or even if there is a better way of doing it. When the group leader clicks on the button the app in each member's device will retrieve the X, Y by the GPS and calculate the distance between the leader's XY and his XY, if the distance is lower than 100 meters for example then the member is present. But problem with that method is that everybody has to have a working internet connection and has to have the location service enabled. I wanna know if there is another way of doing it like with the Wifi for example and what does it require and if there isn't what tools/functions will my idea require in order to make the app. -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
