SQLite Database for Data Storage and Retrieval :
Rapid and efficient data storage and retrieval are essential for a device whose storage capacity is limited by its compact nature.
Android provides a lightweight relational database for each application using SQLite.
By default, each application database is sandboxed — its content is available only to the application that created it — but Content Providers supply a mechanism for the managed sharing of these application databases.
Native Google Maps, Geocoding, and Location-Based Services :
Native map support lets you create a range of map-based applications that leverage the mobility of Android devices. Android lets you create activities that include interactive Google Maps as part of your user interface with full access to maps that you can control programmatically and annotate using Android’s rich graphics library.
Android’s location-based services manage technologies like GPS and Google’s GSM cell-based location technology to determine the device’s current position. These services enforce an abstraction from spe-cifi c location-detecting technology and let you specify minimum requirements (e.g., accuracy or cost) rather than choosing a particular technology.
It also means that your location-based applications will work no matter what technology the host handset supports. To combine maps with locations, Android includes an API for forward and reverse geocoding that lets you fi nd map coordinates for an address, and the address of a map position.
