This document summarizes an Android application project for checking symptoms of tiredness on a smartwatch and handheld device. The application allows users to create text templates on a handheld, displays results on the watch, and syncs data between devices. It uses speech recognition on the watch with some limitations and custom drawing views. The project uses test frameworks and sends data between devices using MessageApi and DataItem.

1. AndroidWear
application development
(R&D Tiredness Symptom Checker)

2. Project key idea
Template generation + pattern matching
Scores and summary screen
Manual tests creation

3. Architecture
Editing on
smartwatch is pretty
challenging - so we
use handheld for
creating text
templates and
displaying list of
results.
Wearable
Handheld
LanguorLib
DAOGenerator

4. Creating templates on handheld
Tools used:
FloatingActionButton, FloatingActionsMenu
ButterKnife
GreenDao (in languorlib)
FragmentPagerAdapter

5. FAB

6. ButterKnife - works with Wear

7. GreenDao - it works with Wear too

8. Speech recognition on AndroidWear
Limitations:
Limited results amount
Disabled custom recognition
animation (that was available
for handhelds)

9. RecognitionListener - cool thing on mobile

10. Speech: RecognizerIntent

11. Drawing. CustomView

12. Drawing. CustomView implementation

13. Drawing. CustomView, attributes

14. ShapeTest - using ShapeView
Sometimes random combinations can confuse

15. Test framework
To run tests we use:
Abstract test framework:
TestRunner, Test,
TestFactory, Score
Concrete implementations (for
example ShapeTest) in UI
fragments
(ShapeTestFragment,
SpeechTestFragment)

16. DataSync: sending data
We send scores from watch to handheld
using MessageApi.
WearableConnector class wraps this
operations for both watch and handheld.

17. Inside WearableConnector. Init

18. MessageApi

19. DataItem
DataItem defines the data interface that the system uses to synchronize data between handhelds
and wearables.
It generally consists of payload - byte array, which you can set with whatever data you wish up to
100KB and path - a unique string that must start with a forward slash (for instance, "/path/to/data")
public static final String DATA_ITEM_ALL_TEMPLATES = "DATA_ITEM_ALL_TEMPLATES";
public static final String DATA_ITEM_ALL_TEMPLATES_PATH = "/all_templates";

20. WearableListenerService
WearableListenerService is registered as usual Android services and can listen for
incoming Messages or DataItems.

21. DelayedConfirmationView

22. DelayedConfirmationView

23. ConfirmationActivity

24. 2D Picker

25. FragmentGridPagerAdapter

26. Application start
From notification
From start menu
From service (onMessage)
