How to keep my accelerometer awake with screen off with Sony SmartwatchMN2

问题

I want to know the method of keeping my accelerometer awake with screen off.
In the developer documentation(SmartWatch_WP_1.pdf in Smart Extension SDK), I read that

• the sensor is stopped when the control is paused
• the control is not paused by using ControlExtention#setScreenState(Control.Intents.SCREEN_STATE_OFF).
• the control is paused by the user operation or time elapses.

So I tried to use ControlExtention#setScreenState(Control.Intents.SCREEN_STATE_OFF).
After one minute, the control was paused and the accelerometer was stopped.
But it was not paused when the power cable connected.
Of course I want to keeping the accelerometer awake when power cable not connected.

I also tried the wakelock(PowerManager.FULL_WAKE_LOCK) and Service#startForeground, but i didn't get well.

Are there ways to resolve this problem?

My Configuration is

• Device
  • Sony Smartwatch MN2
• Smartwatch Version
  • 0.1.A.3.7
• Host Application Version
  • 1.2.37

Thanks!
