I am developing an application in Android Studio in which I connect to a server using SOAP and get something like that TCXXX,lat,long/TCXXX,lat,long
I store each component in array where the latitude and longitude are double .
The problem is that I can not show the points in the app.
How can I show several markers stored in an array on the map?
