14. Keyword :
asynctaks, service, asyncadapter

15. ● an intelligent Thread that is advised to be
used. Intelligent as it can help with it’s
methods, and there are two methods that
run on UI thread, which is good to update
UI components.
● Call from UI thread
● Not for long brackground threat
AsyncTaks

16. ● run in background
● no UI
● run on UI thread (steel need worker thread)
Service

17. ● Plugin architechture
● Automated execution
● Automated network checking
● Improved battery performance
● Account management and authentication
SyncAdapter

18. Good Pattern

19. good pattern using SERVICE–
Activity-UI thread
Service helper
service-UI thread
Workter thread
Content observer
respone
handler
parser
notify
CRUD
Content provider

20. Activity + cursor loader
Content provider
Sync adapter Network layer
CRUD
Get Data for sync Update cache
Content observer
notification
Server request
good pattern using SYNCADAPTER–
