This is a little experiment with ReactNative for Android. The app is really simple:

• It fetches the current location (but not really since Geolocation is not available on Android yet)
• Georeverses it to get a place name via Google APIs
• Get the weather for that place via Yahoo! Weather API
• Fetches Flickr images about this place to display a background.

This is a classic ReactNative Android project, so simply follow Facebook's intructions: ReactNative getting started
