Real time sharing of GPS location [closed]

Question

I'm pretty new in the android world. I am wondering how can I get the position of my friends and display it on a map. More precisely, I don't know how to share the position of my friends and I. Maybe have to use a server or something like that ?

Is it hard to code ?

Thx,

Arnaud

Answer 1

You can look at existing open source solutions.

Here is a server side source code: https://github.com/tananaev/traccar/

And here is Android app: https://github.com/tananaev/traccar-client-android

Communication is done over TCP connection.

• After establishing connection client sends identification message:

$PGID,123456789012345*0F\r\n where 123456789012345 is a unique device identifier, in this case IMEI

• Then client sends location reports with selected interval in standard NMEA RMC format:

$GPRMC,123519,A,4807.038,N,01131.000,E,022.4,084.4,230394,003.1,W*6A

Answer 2

Step-1 Create android app which will share required details like position and name etc and will request to the server for required information

Step-2 Create a server which will store the details sent by the user and sent necessary information to the appropriate client

Approach

When your friend will come online the app should send(installed in your friends device) the detail to the server whenever you want the information your app should request to the server for necessary information
