监听定位开关的时候，在部分手机（应该Android版本较低）上报错如下

原始代码如下

    private val locationListener = object: LocationListener {
        override fun onLocationChanged(location: Location) {
        }

        override fun onProviderDisabled(provider: String) {
            super.onProviderDisabled(provider)
        }

        override fun onProviderEnabled(provider: String) {
            super.onProviderEnabled(provider)
        }
    }

解决办法是去掉两个super，即如下

    private val locationListener = object: LocationListener {
        override fun onLocationChanged(location: Location) {
        }

        override fun onProviderDisabled(provider: String) {
        }

        override fun onProviderEnabled(provider: String) {
        }
    }
