This sample aims to be as close to a real world example of a mobile and Wear app combination as possible. It has a more refined design and also provides a practical example of how a mobile app would interact and communicate with its wear counterpart.
The app itself is modeled after a hypothetical tourist attractions app that notifies the user when they are in close proximity to notable points of interest.
The Wear component shows tourist attraction images and summary information, and provides quick actions for nearby tourist attractions in a GridViewPager UI component.
Steps for trying out this sample:
- Compile and install the mobile app onto your mobile device or emulator.
- Compile and install the wearable app onto your Wear device or emulator. (Note: wearable apps are not automatically pushed from your mobile device unless you build a production release, see here for more info).
- Start the mobile app and use the overflow menu options to test either a notification enhanced for Wear, or the full wearable application (unless you're physically in Sydney in which case the geofence should trigger automatically). Note that the first time you trigger either the notification or the wearable app it may take 20-30 seconds to show up as it needs to transfer the image assets to the wearable (in practice this delay won't be noticeable to users as they will only be notified once the data has been sent).
This sample aims to demonstrate a number of different Android APIs and concepts relating to Android Wear and location using Google Play Services:
- Trigger a mobile notification that uses WearableExtender to customize the display on the wearable
- Transmit data from the mobile app to the wearable (including binary blobs such as photos) using the Wearable DataApi
- Synchronize notification dismissal across mobile and wearable apps via the Wearable MessageApi
- Trigger actions on the mobile app via the wearable app (eg. start walking navigation) via the Wearable MessageApi
- Locate the user via the Google Location APIs and the FusedLocationProviderApi
- Set up and trigger location geofences using the Google Location APIs
The sample also focuses on providing a simple, yet clean design and UI for both mobile and wearable apps with an extra level of visual polish compared to a traditional code sample.
Some of the UI widgets and design patterns used in the mobile app include:
- Use of Material theme including definition of primary and accent colors
- AppCompat usage for Material theme backward compatibility
- Metrics and keylines based on the Material guidelines
- Window content and activity transitions based on the Material guidelines
- Use of the RecyclerView widget
The wearable app uses a number of techniques and UI widgets as well:
- Full screen app built off GridViewPager and DotsPageIndicator
- Support for square and round screens (with and without insets) using WatchViewStub and OnApplyWindowInsetsListener
- Use of a variety of other widgets from the Wearable UI Library (DismissOverlayView, ConfirmationActivity, CardScrollView, CircledImageView)
- Android SDK v22
- Android Build Tools v22.0.1
- Android Support Repository
This sample uses the Gradle build system. To build this project, use the "gradlew build" command or use "Import Project" in Android Studio.
