Sony Smartwatch2 is a wrist watch style device which connects with your Android device and makes you easily access to your data from your wrist. You can view upcoming events in Google calendar, received SMS, tweets, etc.
Sony Smartwatch2 has ４ types of applications.
- Builｔ in
Some basic functions, such as alarm, stopwatch, timer is built in to Smartwatch2 firmware which can run stand alone, without connection to android device.
Notification type app sends notification message / icon from android device to Smartwatch2. Smartwatch2 saves those notification message and notifies user. When android device is disconnected from Smartwatch2, you won’t get new notification, but you can still view saved messages on Smartwatch2. Gmail, tweet app is this type.
Control type app is interactive app which can do lots of things. Smartwatch2 handles input from user and displaying contents, and all other processes are done inside android device. User input is sent from Smartwatch2 to android device, app running on android device does all processing, creating contents to be shown on screen, and screen content is sent to Smartwatch2. Therefore, since Smartwatch2 only handles UI part, android device have to be connected continuously for those type of app to run.
Widget type app became available on April 2014 update. User can place widgets in watchface to customize their watchface. Internally, there are two types of widgets, which works offline and online. Online widgets needs android device to be connected to update display. This type of widgets will shown grayed out when offline.
Apps you can download from Google Play are either one of notification type , control type, or widget type, and no third party developer can create built in (stand alone) type app for Smartwatch2 at this time.
Q:Can anybody create app runs on Smartwatch2 stand alone?
A:No, for above reason. Some watchface widget can run offline.
Q:Where is app preference?
A:Open SmartConnect, Smartwatch2, Smartwatch2 and you will see list of installed extensions. Tap on extension to open preference for each app.
Q:When running app, notification only shows up at top of screen for short time.
A:This is due to SmartWatch2 system design, there’s nothing developer can do about this (maybe many requests from user to Sony support makes system update to support showing full notification).
Symptom below occurs.
- Icon not found after app install.
- Tapping icon only shows progress and then nothing happens.
- Screen freezes.
- Slow, or app aborts.
- Vibration always vibrates for long period of time.
For most of the time, rebooting Android device fixes the problem (since most of the processes are done inside connected android device).
Still problem exists, you can try
- Reboot Smartwatch2 (Long hold power button to shut down, then turn back on)
- Uninstall / reinstall app
- Uninstall / reinstall SmartConnect
- Reset Smartwatch2 to factory mode (from setting icon in Smartwatch2)
For Xperia user, using stamina mode makes Smartwatch2 app to halt when Xperia is in sleep mode. Disable stamina mode, or add Smartwatch2 related apps to active program list.
