“Universal Dev Tools”

Tool Fragmentation

• One‐Time Storefront Purchase• Subscription APIs• In‐App Purchase / AVB• In‐App Advertisements

• Good Industry Patterns:– Hardware Innovation– Open, well‐supported SDKs and APIs– Devices that consistently implement APIs– Multiple billing models – Low‐friction store submissions– Balancing Quality and Quantity in the Stores

• Qualcomm:– $3+ Billion in developer revenue– Consistent SDK and APIs– Consistently implemented on devices– Single submission to multiple storefronts– Good developer support– Good Monetization strategy 

• 1 time billing, subscriptions, demos, IAP

• Carefully select development tools• Carefully select Reference and Target Devices• Effectively use the tools available to you• Learn from past projects & experienced partners• Apply a good QA strategy• Plan a monetization strategy from the start

• Cocos2d• TapJoy• Analytics: Omniture, Flurry• Openfeint• Urban Airship• Open Street Maps• JabFab (http://www.JabFab.com )• AllJoyn

Always check the licenses first

• Consider using OpenGL.• Use the SD Card ‐ it’s faster.  • Use the platform tools ‐‐ XCodeMemory Analyzer, Eclipse MAT, etc.

• Use NDK if you hit Android memory or performance problems.

• Design separately for tablet vs phone.  

• Don't try to make iOS‐native UI widgets on Android, or vice‐versa.

• When converting menu‐driven applications…– Convert the business logic line for line– But create the display logic appropriately for the target platform.

• Design and develop to provide the best of each platforms.

• Don’t go for lowest‐common‐denominator. 

• … but ensure business logic is consistently implemented across platforms.

• “Beautifully Different”• For Apps, start fresh with your design. Follow Metro Guidelines.

• Find an experienced partner or go to training.  

• If converting from an existing app, try to start from an Android codebase.

MS provides some good info...

• CPU processing • Tombstoning• Panorama vs Pivots• Use Live Tiles• Smoothstreaming only• No Flash

QA

• Create Test Plans in conjunction with Design and Development.

• Efficiently address fragmentation.• Always test under multiple network conditions.

• Include automated tools where they make sense.

• Don’t use an API unless there is a clear use case benefitting the user.  

• Be mindful of iOS monetization rules.• Do not use UDIDs.  Use UUIDs.  • Use the iOS configuration.
