Android Question Calculation in background?

[vfafou]

Hello!
My app uses GPS and every LocationChanged I need to check within which polygon belongs the current location.
Which is the best approach:

1. Using Spatialite Library?
2. Calculate by code with lists of coordinates?

What to do in order to not have overflows:

1. Background thread calculation?
2. Every X seconds?

I'm very confused!

Thank you in advance!

1. Measure the time it takes to calculate whether the point is in a polygon.
2. Multiply it by the number of polygons.

My guess is that it will be very very fast and you won't need to do anything special.
