Android SpeedTracker Sample

Sample demonstrates recording location and speed with a Wear device in mind. Location is retrieved via FusedLocatinProvider which retrieves coordinates from the phone or Wear depending on whether the phone is disconnected or not and whether the Wear device has a GPS chip.

Introduction

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).

Sample demonstrates retrieving location and speed samples on Wear using the FusedLocationProvider. It also passes GPS location information back to the mobile device via the Data Layer to be rendered on a Map Fragment.

Pre-requisites

  • Android SDK 26
  • Android Build Tools v26.0.1
  • Android Support Repository

WearableMainActivity

SpeedPickerActivity

WearableMainActivity

SpeedPickerActivity

WearableMainActivity

The main activity for the wearable app. User can pick a speed limit, and after this activity obtains a fix on the GPS, it starts reporting the speed. In addition to showing the current speed, if user's speed gets close to the selected speed limit, the color of speed turns yellow and if the user exceeds the speed limit, it will turn red. In order to show the user that GPS location data is coming in, a small green dot keeps on blinking while GPS data is available.

Ambient mode controller attached to this display. Used by the Activity to see if it is in ambient mode.

Adjusts the visibility of views based on location permissions.

Handles user choices for both speed limit and location permissions (GPS tracking).

Callback received when a permissions request has been completed.

Returns {@code true} if this device has the GPS capabilities.

Prepares the UI for ambient mode.

Restores the UI to active (non-ambient) mode.

SpeedPickerActivity

An activity that presents a list of speeds to user and allows user to pick one, to be used as the current speed limit.
