Android Advanced Techniques
This document discusses techniques for building advanced Android applications. It covers topics like maintaining freshness with location and data updates while minimizing battery drain, adding intelligence with suggestions and account/device syncing, ensuring smoothness by offloading tasks to background threads, following an "invisible" design with standard patterns, prioritizing efficiency through low battery usage and intelligent updates, and testing for reliability. The overall message is to build applications that are fresh, intelligent, smooth, invisible, efficient and reliable.
