To wake the Wear OS watch face at a regular interval.
Build and install the app. Once installed, it will by default be in the disabled state.
The app requires the SYSTEM_ALERT_WINDOW permission, in order to be able to wake the screen from the background.
Grant this using:
adb shell pm grant com.garan.waker android.permission.SYSTEM_ALERT_WINDOW
Once setup, enable the waker using:
adb shell am broadcast -a com.garan.waker.SET_WAKEUP_ON com.garan.waker
To disable again:
adb shell am broadcast -a com.garan.waker.SET_WAKEUP_OFF com.garan.waker
Specify an interval in seconds:
shell am broadcast -a com.garan.waker.SET_WAKEUP_INTERVAL --ei interval_seconds <seconds> com.garan.waker
