ARO Background
ARO Manual Test (Demo!)
ARO Analysis
ARO Automation (NEW!)
12. Find The Issues Early With ARO
ARO Records and Analyzes Network Interactions of App
Network use
accounts for
40-70% of
battery drain!
13. ARO Requirements
• Open Source and Free
Developer.att.com/ARO
• Required for AT&T Preload apps
• iOS
- Requires iOS device tethered to Mac (with Xcode)
• Android
- Requires Android device tethered to Mac/PC (with
Android SDK)
14. Testing Your App With ARO
1. Move at a speed that emulates real users
2. Create flexible (yet reproducible) test cases
a. Test cases can even reflect more of a feature checklist
b. The Trace is not about the order of the features, but about the content
3. Likely Problem Areas
a. Startup
b. Streaming
4. Be Curious
a. If something seems odd, explore it
b. Screen rotation best practice came out of tester noticing the network
lighting up each time they turned the device
5. Background Data:
a. Run long test with app running in background
16. Demo Backup Slides

analyzed
23. Download Less Stuff: Caching
17% of HTTP content on mobile is duplicate data
– Reading from Cache is 75-99% faster than
downloading again
“Web Caching on Smartphones: Ideal vs. Reality”,
http://www.research.att.com/~sen/pub/Caching_mobisys12.pdf
6.7MB 6.7MB
4.8 MB duplicate!
75% possible
savings!
(data AND speed)
24. Caching Methods (How do I do it?)
ETags
Cache Control Headers
•Each file has a Unique Tag
•Revalidated on server for each request
– High Performance Web Sites:
Rule 1 – Make Fewer HTTP Requests (1)
– Adding a connection drains battery,
adds 500-3,000 ms latency
•Important to carefully assign Max-Age times
•App will not check file on server until Max-Age
is reached
– Retrieval is strictly file processing time
(1) http://developer.yahoo.com/blogs/ydn/posts/2007/04/rule_1_make_few/
25. Comparing ETag vs. Cache Control
Network Usage Battery Drain Data Usage Speed
NO Cache
YES entire file
downloaded
Full network
connection made
High Slowest
ETag
Yes – ETag in cache
is validated on server
Full network
connection
Low Slow
Cache Control No N/A N/A Fast
Any Caching is better than no caching, but for mobile, Cache Control is preferred
35. Periodic Connections in the Background!
Background traffic
Many Apps wake up in the background to update data or
communicate with servers.
Just 10 background connections = 0.5% battery/day
And it adds up FAST!
Look at Android’s JobScheduler API (5.0 and up)
