I have to generate Notification Alert whenever my current location get match with the location stored in the Database. So I used google places API for user type the location and then it get stored in the database so i have to write one service for getting current location from LocationListener and then how can I check location stored in database?

Can any one suggest me that how to check ? with the help of location text with the current text or getting latitude and longitude ?
