Android Question Location

[RUNO]

My app for delivery.
Can I create an area dependent on longitude and latitude and save it in a database and check the customer's location inside or outside region.

yes. hard to say what you might already know or not know how to do... gps, fused location, sqlite, geofence. search them here. geofence is the key element in this case.

What result I get?
I changed the center point and radius, I want to check the location inside the circle or not, how?
I want a result.

You can use:

Distance = CenterLocation.DistanceTo(LocationToCheck)

If Distance <= Radius Then
    ' insides
Else
    ' outsides
End If

You know the location of your center and you know the locations to check, so can calculate the distance between those with DistanceTo method of the Location object in the GPS library.
