创建一个Android unity3d插件棉花糖6.0危险权限

Question

嗨，我目前正在尝试在Unity3D中构建所谓的android plugin：NoodlePermissionGranter，以便可以在运行时请求危险的权限。

我在关于stackoverflow的另一个问题上找到了该插件。

从主题使用的答案：[ 在unity3d中实现Android 6.0权限 ]

我进行了一些更改，以使其易于构建，但无法正常工作。

如果尚未授予该插件，则应该请求危险的许可。 尝试请求权限时，它会立即回调到PERMISSION_DENIED。

预先为我的英语不好对不起。

编辑 ：没有错误。

请务必检查您的android清单是否具有危险权限！

那是我的问题。
