I am new to Android studio and i am learning it for a few days. I was trying to implement a map in which we can set two markers to find the route between them. Today I was trying to implement waypoints between them. After setting the waypoints in the map the old route between two marker i.e. from origin to destination is not removed. I am getting the old route as well as the new route from origin to waypoint to destination. Note: I am trying to implement two waypoints so if i set one waypoint it will show new route(origin-waypoint-destination) and If i set two waypoints it will show new route(origin-waypoint-waypoint1-destination) removing the old one.

The code is below: Map Activity

''' public class MapsActivity extends FragmentActivity implements OnMapReadyCallback {

I'm trying to work with spatial data types which I find to be not so widely understood on the internet as compared to other programming topics.

I have a table which contains objects on a map. Coordinates go from 0,0 to infinity in any direction, theoretically. There can not be more than 1 object at a point on the map so I designed the table like so:

I am getting this error when trying to search a place on map. I tried other resolutions when searching, but no luck.

java.lang.IllegalStateException: no included points

on this line: LatLngBounds.Builder builder = new LatLngBounds.Builder();

The code I am using:

I want to get the distance and duration for example in this https://maps.googleapis.com/maps/api/directions/json?key=API_Key&sensor=true&language=en&origin=6.035507,116.1213559&destination=5.9699316,116.0665816. I have already get the route in between these 2 locations. But I don't know how to get the distance and duration displayed. Need some help. I already knew the others already posted this question, but it seems cannot work with my code due to I am consider a rookie in Android. Below is my code:

I'm relatively new to python so I'm sorry in advance if I'm asking too dumb questions

I have CSV file with following columns: 'CarNumber','DateTime', 'GPS', 'Speed'. GPS column contains information in the form of: 'Latitude : Longitude'

I want to:

1) Load CSV file

2) Split GPS column to Latitude and Longitude columns

3) Apply Haversine formula in order to calculate distance between two points with known Latitude and Longitude. So far I've come up with following function:

My app saves user location into Firebase database. I need to compare current location with the location saved in Firebase to avoid same location to be saved in database (if user is at same place). How can I achieve this?

Here is my code.It doesn't give desired output as it stores same location again n again without comparing.

Hi everyone, I'm try to search LatLng from firebase real-time database within 1 kilometer radius using cloud function. But I'm facing a problem following blew that have showed in Logs.

• Billing account not configured. External network is not accessible and quotas are severely limited. Configure billing account to remove these restrictions
• Function execution took 60002 ms, finished with status: 'timeout'

My primary goal is to get the distance between two points. I'm trying to calculate the distance in miles between the start/end of a polyline. Using the code below I was able to draw a polyline. However, I don't know how to get the total distance of this polyline.

I'm getting issue when I try to use < symbol with AND condition in sql query.
