Android Notifications Sample

Sample demonstrates best practices for using NotificationStyle Notifications (Inbox, BigPicture, BigText, and Messaging) for both Mobile apps and native/local Wear apps. It also covers Notifications on Wear 1.+ and Wear 2.0.


Steps for trying out the sample:

  • Compile and install the mobile app onto your mobile device or emulator (for mobile scenario).
  • Compile and install the wearable app onto your Wear device or emulator (for Wear scenario).

This sample demonstrate best practices for using NotificationStyle Notifications for two scenarios:

  1. Launching Notifications from a Mobile app WITHOUT a native Wear app. Notifications appear both on mobile and Wear (bridged to appear like a local/native Wear app).

  2. Launching Notifications from a Native/Local Wear app. Notifications only appear on Wear device.

The Mobile and Wear apps demonstrate BigTextStyle, BigPictureStyle, InboxStyle, and MessagingStyle Notifications.

Although there are two apps (Mobile and Wear) running, each should be looked at as a separate experience. That is, neither app uses nor relies on the other.

They are packaged together simply to show both scenarios in one easy sample.

Both apps also cover the Notifications being displayed on Wear 1.+ and/or Wear 2.0 and using some of the new features of Wear 2.0 (inline actions).
