Droidcon London 2010 - Create Killer Location Apps

Hinweis der Redaktion

2. Audience have used location services. How many used Rummble? Some already building location-centric apps. Some have apps and trying to work out how to integrate location.
3. Thanks for making first session. We living in the distant future... (according to Doc Brown) So let’s travel back in time to 1995 for some interactive trivia. I hope you’re awake!
4. 0.4% of world pop
5. 8.6% world pop
6. 8.6% world pop
7. Making assumption that most people on Twitter or other social networks have FB account. FB Launched in 2004, so < 3 years to get achieve same growth as internet.
8. Market size Google Maps, Local Search or Check-in service? Network effect... next slide
9. 1908 Theodore Vail, Bell Telephone annual report. Network effect much greater now - more connections, accelerated growth... ...building upon internet and social.
10. Rummble’s Q3 revenue.... 28.8% of world pop

38. The Geolocation object is used by scripts to programmatically determine the location information associated with the hosting device. The location information is acquired by applying a user-agent specific algorithm, creating a Position object, and populating that object with appropriate data accordingly. Objects implementing the Navigator interface (e.g. the window.navigator object) must also implement the NavigatorGeolocation interface [NAVIGATOR]. An instance ofNavigatorGeolocation would be then obtained by using binding-specific casting methods on an instance of Navigator. 4.1 Privacy considerations for implementors of the Geolocation API User agents must not send location information to Web sites without the express permission of the user. User agents must acquire permission through a user interface, unless they have prearranged trust relationships with users, as described below. The user interface must include the URI of the document origin [DOCUMENTORIGIN]. Those permissions that are acquired through the user interface and that are preserved beyond the current browsing session (i.e. beyond the time when the browsing context[BROWSINGCONTEXT] is navigated to another URL) must be revocable and user agents must respect revoked permissions.

We’ve looked at available OS solutions (note examples) and the quality is bad. Scraping can be more expensive and time consuming. Can run into legal issues. Quality? Unified open location DB

63. Used to create boundaries, also contains some POI data....
69. Levels the playing field as far as check-ins are concerned... Can’t input lat,long yet...
70. Index, interpret and consume location Cloud infrastructure
71. Data Marketplace Spotrank
75. Quality of response fine for most apps, but will vary between services. Geocode on the client side where possible - i.e. use the Javascript SDK. List<Address>
76. Used to cost a fortune. People usually want to know how to find a place, but best to export leave this to Google Maps... Can get Bing tiles???
78. Group notificationsSimple to customise / turn off via app
