[FREE] AddressInfo - Some calculations about address


Hello every one…Today I introduce my first extension…It’s an extension that makes some calculation about addresses…
Currently it only supports getting distance between two coordinates…And also indicates if a coordinate is in a radius around a location…
Note: This extension doesn’t use any formula in calculation…It uses a class for calculation provided by android…So calculating is more accurate…

Distance between

Returns the distance between two points in meters.Returns -1 if coordinates isn’t valid.
latA ~ int
lngA ~ int
latB ~ int
lngB ~ int

Is in radius

component_method (12)
Returns true if a specific coordinates is in a specific radius.
targetLat ~ int
targetLng ~ int
positionLat ~ int
positionLng ~ int
Radius ~ int

Usage example

That’s represents how far i am from london in meters ( can be easily converted to kilometres):

That represents if i’m in circle around london it’s radius 6000m:

thank you for your contribution…
I only have some minor naming conventions remarks… :grimacing:

Please follow the naming conventions, which is UpperCamelCase for property, method and event names (i.e. the first letter should be a capital letter) and lowerCamelCase for parameter names, no underscores .

Which means in your case, you should write targetLat rather than targetlat, same for targetLng, positionLat, positionLng
there also is a spelling error for DistanceBetween and ErrorOccurred



Thanks so much @Mohamed_Tamer great work !!!
Can I suggest post some phone screenshot about can be done with this extension.

i have a button.
i have a school.
i want the button only visible when my position is in 50 radius of my school. How to set the block with your extension?

:one:, you must have your school coordinates( latitude and longitude)…
:two:, grab IsInRadius block from the extension…
:three:, set the target lat and lng to the coordinates of your school…
:four:,Set the position lat and lng to the coordinates ( it’s latitude and longitude) of the device…You can get it using location sensor component…
:five:, set the radius to 50… Note that the radius is in meters so if you want 50 km then set it to 50000…
:six:, You are done!


the first step, do i have to use map component for it?
to get lat and long…

Nope, you can easily get the longitude and latitude of your school using those two blocks in the location sensor component…
