android - Get location of other people in Google Maps -

I am developing an Android app that allows people to call numbers through their legal Tracks with consent.

For some reason, I can not find any related topics in Google or I can not build the right words.

Google Maps and others have already been setup I just need some basic infos to approximate LatLng s and those people.

Where do I start? Or a recommended link?

If you are tracking many people with their consent, then I'm assuming that your app If this is the case for every user running on their personal device, then use the Android Geolocation API to get the device's lat long and publish the backend on the cloud from time to time (many backend Every minute or so to avoid writing) You can use a key / value storage to store the conic, where the key is the user identifier, and this value is the last latitude / long (I can also suggest that the last update to identify the previous update To store a timestamp).

You can again get backend query / membership (A) to the last lat / long of the specific user (u), and then use it to create a custom marker on the GMap API .

We are working on a platform that uses the same logic but for a different use-case, calculates close to specific locations and provides actions based on proximity.

I hope this helps us we are using Ionic / Angular for our build platform so that we can use the PhoneGap API to access the device's geographic location services.
