Android requestLocationUpdates中不更新的最小时间间隔

我正在开发一款android应用程序，它每隔5分钟为我提供一次位置信息。现在，如果用户收到一个电话，那么我将更新5分到5秒，这样我可以每隔5秒获得用户位置，直到他接听电话为止，这样我就可以计算一个人接听电话时的速度。我每5分钟获取一次用户位置，这很正常，但当我在CALL_STATE_OFFHOOK中将此时间更新为5秒时，它不会将时间更新为5秒。我仍然在5分钟内获取位置。请帮助

 @Override
public void onCallStateChanged(int state, String incomingNumber) {
    super.onCallStateChanged(state, incomingNumber);
    log.info("onCallStateChanged called");

    switch (state) {
    case TelephonyManager.CALL_STATE_IDLE:
        BackgroundService.LOCATION_INTERVAL = 300000;
        log.info("onCallStateChanged  CALL_STATE_IDLE():");
        //Toast.makeText(context, "Phone state Idle", Toast.LENGTH_LONG).show();
        break;
    case TelephonyManager.CALL_STATE_OFFHOOK:
        BackgroundService.LOCATION_INTERVAL = 5000;
        log.info("onCallStateChanged  CALL_STATE_OFFHOOK()");
        //Toast.makeText(context, "Phone state Off hook", Toast.LENGTH_LONG).show();
        break;
      case TelephonyManager.CALL_STATE_RINGING:
          log.info("call state ringing before");
         // BackgroundService.LOCATION_INTERVAL = 00000;
          log.info("call state ringing after");
        //Toast.makeText(context, "Phone state Ringing", Toast.LENGTH_LONG).show();
        break;
    default:
        break;
    }

}

也许使用加速计来获取用户速度是更好的主意，但我在mLocationManager.requestLocationUpdates（LocationManager.NETWORK_提供程序、LOCATION_间隔、LOCATION_距离、mLocationListeners[1]，Looper.getMainLooper（））中停留在更新时间上；也许使用加速计来获取用户速度是更好的主意，但我在mLocationManager.requestLocationUpdates（LocationManager.NETWORK_提供程序、LOCATION_间隔、LOCATION_距离、mLocationListeners[1]，Looper.getMainLooper（））中停留在更新时间上；
