google 地图自定义样式 - 饱和度、亮度不起作用

Question

我正在尝试使用 google 地图 android sdk 在 android 上使用自定义地图样式。大多数更改和自定义样式正在设置和工作。但是，在图标上设置饱和度或亮度不起作用 - 如果我尝试在图标上设置饱和度或亮度（poi，labels.icon），那么图标会完全消失。

删除饱和度和亮度值会导致图标再次出现。

json 是从 google 地图样式向导 (https://mapstyle.withgoogle.com) 生成的。

这正是我用过的 json：

      {

这是 Google 地图 Android API 中的一个已知问题。前一段时间在 Google 问题跟踪器中报告过：

Google 已于 2018 年 10 月 11 日将此问题标记为已修复。

Google Maps Android SDK 的发行说明中也提到了这一事实：
