Proximity Alert

Question

I want to make an application for Android 2.2+, utilizing the GPS. Basically I want to be able to set a specific zone in the app, using google maps.

Example: I am walking to the store, as soon as I am x (variable) meters away from my house I want an alarm going off on my phone.

I googled and saw that you can use proximity alerts to get a notification when you are close to a friends house or something like that. They used specific coordinates for this. I want to be able to draw a line on a map or use a street name, and as soon as i cross that line i want an alarm to go off. If anyone could point me to some tutorial for that part or give some advice, that would be great.

Answer 1

I think you need to map your line in google maps yourself with some formula.

Proximity alerts work with a radius. You might need to set up multiple points with a small radius along your line.

You will get either the entering Intent or the exiting intent.
