Android: prevent your phone’s vibration from being affected by accelerometer data

Question

I developed an application that tracks when I am moving with the accelerometer, and I can vibrate the phone depending on the various thresholds that I may have pressed. One of the problems that I have encountered is that this vibration directly distorts the accelerometer data.

This answer suggested using a low-pass filter, but I don’t think it would work in this application (I need relatively fast response times and vibrations cause big bursts in the data).

The solution I am currently using is to set the flag to true before the phone vibrates, call a function postDelayedthat will return it false after a certain time (1 second is ok) and in onSensorChanged, just return if the flag is true.

In other words:

isPhoneVibrating = true; // Start to vibrate     
phoneVibrator.vibrate(VibratePattern, -1);
mHandler.postDelayed(vibrateSensorOff, 1000); // 1 seconds wait before making false

vibrateSensorOff contains only

isPhoneVibrating = false;

and, as I said, in the function onSensorChangedI return if the flag isPhoneVibratingis true.

I do not like this solution because I need to manage this extra flag in different states of this application. Are there other possible solutions that do not require an additional flag?
