@pipechela,
I want the restaurants that are close to my current location.
You can use Google maps Api.

Yes.
@plantdoc2018 made an app using maps Api for app competition.
Also AIA file is open source and downloadable.
Note: The apk will not work until you edit the AIA by putting your own Google Place API key on right position.
I saw the model, but I need something like this: Image below
according to my location, listview will carry those closest to me
I mean, the data
@welingtongoncalvesfranca This is clearly an API service (possibly Google places API service, not sure) from where the data were being received. And the query parameters obviously included your location (geocordinates).
I can create this using firebase. No api needed .
yes i can create such list with location sensor. it takes lots of time and efforts to do so . so it will be paid. but its possible .
I think you are talking about listview design only its not a big deal @welingtongoncalvesfranca wants functionality i think foursquare api will help
@ShaikhSajidAli What´s “foursquare api” ?
I don’t know if I open another topic or stay here.
I await the suggestions of the moderators.
As I have experience with databases, I designed the app the way I describe below.
What I have in mind to do the same thing as @welingtongoncalvesfranca:
- 1 app for users
- 1 app for sellers - owners
- 1 mysql database with tables: users, sellers.
- invoke a script, to record longitude and latitude, within the “location changed” method. This may not be necessary as the stores (restaurants, pharmacies, etc.) are in fixed places. This idea would be if the sellers were moving (UBER).
- Do a search in the SELECT database on what the user is looking for (PHP script) and return the stores that the user wants.
-The question is how to calculate the current distance from the user (location sensor) to the seller (pharmacy, restaurant) according to the address recorded in the database?
I found.
DistanceCalc : Calculate distance between two places from coordinates

you can use the openrouteservice.org api. They provided a route in json format, and other data, included the distance of that route

Where do I find the “manual” for consuming the API?
you must create and account, and then create a apikey

The manual
https://openrouteservice.org/dev/#/api-docs
For example, the directions, have this response

No need to reinvent the wheel!
Thanks !!!

Your tip is great. But, the mini world that I have to create the app is a little different. The idea is that each service provider has its own location recorded in the bank, at the time of registration, and that the customer with his current location can have the closest distance, based on the locations previously recorded in the database.
But you only have to do it’s to create a database with the provider location. Then use the coordinate of that location as the goal point. Your current location is the start point. Then create a procedure for calculate the distances, and choose the closests one
