notification template

Android 17 will introduce a new "Metric Style" notification template for Live Updates, enhancing user experience by allowing health, fitness, timers, and travel applications to present vital information more accessibly. The Metric Style template can showcase up to three distinct data points simultaneously on the Always-On Display, lock screen, and status bar, focusing on real-time raw data rather than milestones. It features three display modes: a glanceable view prioritizing the most relevant metric, an expanded view showing all metrics side-by-side, and a collapsed view condensing information into a single line. This standardization provides app developers with a reliable framework for delivering critical information directly on the lock screen and status bar. Google has not confirmed whether this feature will be included in the first stable Android 17 update or a subsequent QPR release.
