问题
In this app first i fetch current user data from firebase then get alluser data except current user data then i fetch real time current location and then update location of current user when user start geofense then it craete geofense as many as allotheruser except current user(if there is 5 other user except current user then i create geofense 5 times, give user uid as geofense id, and for geofense center i gave current user current location same center for all 5 geofense),
when this app is run and marker enter in geofense or exit from geofense it give meaningless result.
meaningless result means if otheruser marker didn't enter in geofense it give entring if user entering in geofense then it give enter some time some time don't as well as if otheruser marker exit from geofense then it give enter not exit
i want notification when allotheruser marker enter or exit from geofense
