show the current position of the user on google maps with a marker and the positions of different stations received from the server

hello everyone I am doing a university project and I have to show on google maps the railway stations received from the Server (with a marker and PolylineOptions) and the current position of the user (with a marker). The problem is showing the user's current location (the problem is the code shown in ** bold). My code is:
public class MapsLine extends Fragment {
private String sid_user;
private int did;
GoogleMap map;
private static final int MY_PERMISSION_REQUEST_ACCESS_FINE_LOCATION = 0;
Location currentLocation;
FusedLocationProviderClient fusedLocationProviderClient;
private static final int REQUEST_CODE = 101;

Google map shows output only when code is debugged

I have a google map v2 code which shows multiple markers on a route returned from google api on the device's screen.
The desired output is seen only when the code is debugged.
But when i run the same code on the same device i see a blank screen.
Please help me out.
I have tried :
1) uninstalling and then re-installing the app
2) clean and rebuild the project
3) restarting the device and location permissions
4) restarting android studio and trying again.
5) Keeping and removing breakpoints.
But nothing worked.Need help !!

How to calculate accurate distance travelled by the user using google maps?

I am having two doubts because today only i started doing projects on google maps my first doubt is
How to calculate distance traveled by user when using google maps ?
like how taxi app is calculating the distance, now let me explain my problem in depth regarding this question i have checkin and check out button in map when user click the checkin button i will take that exact lat and long of that user when user checkout i will fetch the lat and long from where he checked out, after i will send this source latlong and destination latlong to google api this will return the kilometer. But what i need is wherever he traveled he may traveled extra bit of kilometer i need to calculate that also how can i do that.
My second doubt is my google maps taking long time to plot the blue mark in my map it shows searching for gps in notification bar how can i achieve this ?
Below is my complete Code

Searched alot and not getting proper way to start with? Any help would really valuable.
--Thanks!

This worked for me:
Capture the latitude and longitude at regular intervals and store. Calculate and sum the distance between each stored value.

Getting the phone number of nearby place

I've been following this tutorial on displaying nearby places, in my case I need nearby hospitals. I'm able to show my current location and display nearby hospitals. But what I want to do is add the telephone number of those hospitals being displayed. I've tried adding formatted_phone_number in my code but it doesn't display the correct phone number but instead displays "-NA-" which is the default in the event that there's no number available.
Any help would be greatly appreciated thanks!

In MapsActivity.class, function getUrl() is taking "Hospital" as one of the arguments which is not in the list of supported types. So, the result type is default, since it doesn't match any supported types.
The response will give you all the places nearby search request for places of type 'default'. To make a request to Nearby Places API to get nearby hospitals, pass hospital instead of Hospital.
In the code, you make a request to Nearby Places API, formatted_phone_number is not returned in response. For more information, refer to the documentation.
To get the phone number(formatted_phone_number or international_phone_number) make a request to Place Details API with the PlaceId.
To get more clarity, enter the url in the browser and look at the response.
Hope this helps you. Good luck :)
