I am making an app for smartwatch in android. A part of the app consists in knowing if there are other android devices near to count every time another device is near. But I don’t know exactly how to make that. I had thought about using gps to get my location and see if other devices locations are near, because the app will be used outdoors. I know how to get my location but I don’t know how to get other devices location or receive other devices location. I don’t know if that would be a good option or if there are other options. Thank you.
