Please help me I have been stuck for months trying to get a toast to pop up using location

[StacksIndeed]

Basically I have it set up now where it will display the users coordinates when you push a button. Id like to have it so that when the users coordinates are being updated all the time (I downloaded the location polling GPS function from the marketplace) but I do not know how to make a pop up or a toast appear when the user is at a certain location. Id like to start with something simple like when they are about 20 meters away from a good restaurant in town. 

I have it so that when i push a button it shows my coordinates, but I dont understand how to compare those to the coordinates of a place in town. I have been reading the learning journys and watching videos. Iv been trying everything for so long now im getting really discouraged. 

I have Variables set up to get the users lat and longitude data, I also have set app variables to store the Hotel coordinates but i dont understand what im doing wrong.

I am a software developer, learning still clearly lol. Im surprised that I find I'm getting closer using Kotlin and android studio than I am using this supposedly easier method.

With the polling, you can create 2 page variables:

• polling - true/false
• currentLocation, an object with lat and lon text fields

Then create buttons to start and stop polling and o display the latitude and longitude values.

Then you can create a simple logic flow:

1. Start polling
2. Set indicator to start regularly getting location values
3. Set up a loop (Delay)
4. Each time get the latest geolocation values, and put in your variable.
5. If we are still polling, go around again.

The other button stops the polling.
