Chapter 9. Marvels of the World around Us

In this chapter, we will be developing an application that shows photos taken around the users location. The application will use Geolocation to determine the device's current location. It will then use the same coordinates to query a web service and retrieve photos that were shot near those coordinates. Our user will then be able to select a particular photo from the list and display it on the screen. We will also give our user the ability to add a photo they like to their photo galleries.

By the end of this chapter, you will have covered the following concepts:

• Getting the device's coordinates
• Retrieving photos based on nearby locations
• Displaying the pictures using the new ListView component
• Saving the desired pictures to the device's Image Gallery
