在Sony Xperia Z2上的onLocationAvailability回调中，FusedLocationProviderClient始终返回false

Question

在索尼Xperia Z2上的onLocation可用性回调中，FusedLocationProviderClient总是返回false。权限已授予，位置已启用。在位置偏好设置选项使用无线上网，网络和全球定位系统。模拟器，三星，BQ，Nexus，小米一切正常。操作系统版本从6到8。但是在索尼（andorid 6.0.1）我有这个问题。有什么想法吗？我已经结束了

private val mUserLocationCallback = object : LocationCallback() {

    override fun onLocationAvailability(locationAvailability: LocationAvailability?) {
        super.onLocationAvailability(locationAvailability)
        val isAvalable = locationAvailability?.isLocationAvailable ?: false
        if (!isAvalable) {
            mLocationHelperListener.onLocationUnAvailable()
            mDefaulLocation?.let { mLocationHelperListener.onLocationHelperChanged(it) }
            stopLocationUpdates()
        }
    }

    override fun onLocationResult(locationResult: LocationResult?) {

        if (locationResult != null) {
            for (location in locationResult.locations) {
                mPreferences?.lastLatitude = location.latitude.toFloat()
                mPreferences?.lastLongitude = location.longitude.toFloat()
                mLocationHelperListener.onLocationHelperChanged(location)
                stopLocationUpdates()
                break
            }
        }

    }
}

要求

val locationRequest = LocationRequest.create()
                    .setPriority(LocationRequest.PRIORITY_BALANCED_POWER_ACCURACY)
                    .setInterval(UPDATE_INTERVAL)
                    .setFastestInterval(FASTEST_INTERVAL)
                    .setSmallestDisplacement(SMALLEST_DISTANCE)


            // Create LocationSettingsRequest object using location request
            val builder = LocationSettingsRequest.Builder()
            builder.addLocationRequest(locationRequest)
            val locationSettingsRequest = builder.build()

            val settingsClient = LocationServices.getSettingsClient(mContext)
            val task = settingsClient.checkLocationSettings(locationSettingsRequest)
            task.addOnSuccessListener { locationSettingsResponse: LocationSettingsResponse? ->
                mFusedLocationClient.requestLocationUpdates(locationRequest, mUserLocationCallback, null)
            }
            task.addOnFailureListener { exception: Exception ->
                mLocationHelperListener.onLocationUnAvailable()
            }

Answer 1

我想我找到了解决办法。我认为我的解决方案将适用于具有相同问题的其他设备。所以转到应用程序列表，查找Google PLay服务。打开权限。如果“位置”权限已关闭，请打开它。如果没有此类项目，请关闭所有项目，然后再次打开。您应该看到位置权限对话框。启用它，瞧，我的情况下一切都正常了。

我有一个非常相似的问题；重启我的手机解决了这个问题。我在几个设备上进行了测试，但唯一有问题的设备是中兴Maven Z812。
