android - How to count steps using an accelerometer while phone screen is off -


i have been using algorithm - (how calculate exact foot step count using accelerometer in android?) calculate number of steps taken. unregister sensor manager listener in onpause() method of activity. 

msensormanager.unregisterlistener(this);

when phone's screen off, steps aren't counted. how count steps using accelerometer when phone's screen switched off? please guide me.

you should read activity lifecycle first. onpause method called when screen turns off, not listening when screen off. instead use background service listen continuously accelerometer sensor.
