![Project Suggestions
• Web Scrapers [movies, weather, sports, <topic> news]
o Find multiple web sources
o Scrape them for the relevant information
o Present in a custom UI on the phone
• Asynchronous games [chess, poker, risk]
o Develop an API for all games to communicate through
1.Establish connections by phone number
– Send and receive game data
– Ability to reopen connections
• Planner/To-do list with location data
o Decide route to next class, meeting, etc
o Find a order/route for non time-critical tasks
o Connect to campus directory to find
teachers/classmates](https://image.slidesharecdn.com/androidslides-131007082501-phpapp01/85/Android-slides-8-320.jpg)

- 2. Android An Open Handset Alliance Project • http://code.google.com/android • Write apps to run on mobile phones • Will be released as open source • Can download the SDK today!
- 3. Android Features • Application Framework • Dalvik virtual machine • Integrated (webkit) browser • 2D and 3D graphics APIs with HW • SQLite • Video and audio codecs • Bluetooth, EDGE, 3G, and WiFi • Camera, GPS, compass, and accelerometer
- 5. Challenges • CPU typically runs 500-600 Mhz • RAM available to an App may only be a few megabytes • Disk (flash) access is very slow • Lifecycle - apps must pause/quit often, and restore to give the illusion that they are always running • UI design o typical screen may be HVGA (320x480) o may be in portrait or landscape o very high DPI - small text may not be readable o touch resolution is very low (~25 pixel) • Network access may be slow and (very) intermittent
- 6. Opportunities • 100s of millions of mobile phone users • Very high growth, esp. in Asia • "Wild wild west" of application development o think 1985 on the desktop (if you were born by then) o no dominant 3rd party developers.... yet o what will the killer app categories be? o what does it mean to have any app + the internet in your pocket? • You can develop for it today!
- 7. Possibilities Augmented Campus Reality • camera + maps + compass = heads up info Games • multi-player (bluetooth, wifi, cell) • location-based (scavenger hunt) Custom overlays for maps • weather, traffic, friends Web scraping • news filters • sport scores • dook news eliminators Distributed computing? • 10,000 phones all donating their idle time • tiny terminal (phone) + fast cpu/network (server) Shared whiteboard
