Java 创建android unity3d插件棉花糖6.0

您好，我目前正在尝试在Unity3D中构建所谓的android插件：NoodlePermissionGranter，这样我就可以在运行时请求危险的权限

我在stackoverflow的另一个问题上找到了插件

从主题中使用的答案：[ ]

我做了一些修改，使它更容易构建，但它没有按预期工作

如果插件还没有被授予权限，它应该请求一个危险的权限。 当尝试请求权限时，它会立即调用back to permission_DENIED

提前为我的英语不好道歉

编辑：无错误

确保检查您的android清单是否具有危险权限

这就是我的问题。

请务必检查您的android清单是否具有危险的权限

那是我的问题
