Check in with Google maps API

My comment will not help you with your question but I thought this may be of some interest. It appears to be more conceptual book - but it may relate to your project efforts.

Can you look into Proximity Alert combined with Location Manager? I am wondering if using the StackOverflow example to query the longitude and latitude. Then use coordinates in the proximity alert example?

The Android Developer’s Cookbook: Building Applications with the Android SDK
TheLocationManager provides a method to set a proximity alert.This triggers an alert
when a user enters or leaves a defined area.The area is specified by a latitude-longitude
coordinate and a radius in meters.The alert is specified with a PendingIntentto be
launched whenever a user enters or leaves the specified area.An expiration time for the
alert can also be defined.

double mlatitude=35.41;
double mlongitude=139.46;
float mRadius=500f; // in meters
long expiration=-1; //-1 never expires or use milliseconds
Intent mIntent = new Intent("You entered the defined area");
PendingIntent mFireIntent
= PendingIntent.getBroadCast(this, -1, mIntent, 0);
mLocationManager.addProximityAlert(mlatitude, mlongitude,
mRadius, expiration, mFireIntent);

The Google Places API was the best solution.
