Break Timer: the app idea
Thinking for the wear
• Build something that doesn’t compete with phone but augment it!
• Context aware app with minimum interaction.
• we tried to step ahead to find the context thats available exclusive to watch.
Break Timer
Problem: If you use computer for 3-4 hours a day and sit continuously in a similar posture, you are at risk of RSI (Repetitive Strain Injury).
The Solution: Break Timer sits silently on your wrist and remind you to take break if you are typing for long intervals to avoid RSI. [Facebook counts!]
• Uses the accelerometer available on watch to see if you are continuously typing.

Learning Journey
• The app idea
• Coding Tips
• Problems we faced during development.
Coding Tricks
• Use common module for keeping models and constants.
Coding Tricks• Should implement some logic on both mobile
and watch to handle disconnect issues
Coding Tricks
Notification mNotification = new NotificationCompat.Builder(context)
.setSmallIcon(R.drawable.appicon) ….. .setCustomSizePreset(NotificationCompat.WearableExtender.SIZE_FULL_SCREEN) .setDisplayIntent(displayPendingIntent).build()
• Embedded Activity in notification with different sizes
Learning Journey
• The app idea and android-wear UX
• Coding Tricks
• Problems we faced during development
Problems faced• Permissions
• apk cache
• Problems with emulators
• No accelerometer
• Round emulator is not as good as square counter part.
Problems faced
• Permissions
• Include all permissions in your handheld device that you need to use in watch.
• Otherwise, it will not auto install the embedded apk
Problems faced
• APK cache
• After lot of try and error, we found the the android-wear companion app was somehow caching and pushing old apk to watch
Problems faced• Round emulator is not as good as the
square counter part.

recap• android-wear is android extension for wearables
• the major concept is to avoid distractions and keep the interaction with gadgets to minimum
• The android-wear is only meant to work with its companion device.
• Since wearables are attached to body, they can provide additional useful context related to user’s current physical state or health.
• Its easier to integrate android-wear functionality in your app, though you need to think wisely.
• The developer tools are still new and buggy and its sometime difficult to get solution to your coding issues.
