启动相机android权限时崩溃[重复]

Question

此问题已经在这里有了答案：

How get permission for camera in android.(Specifically Marshmallow)（6个答案）

关闭54秒前。

我正在使用导入的Scalibrary module示例应用程序进行图像处理过滤器。它有两个主要按钮可打开相机并打开图库。

它在android kitkat上工作正常，但是当我尝试在android 9上启动相机时它崩溃了>>

我尝试在清单上添加：android:requestLegacyExternalStorage="true"，但没有运气

注意：我已经授予了摄像头和外部写入读取存储的权限清单

我想念的是什么？

嗨，您可以将清单文件中的这些权限与其他权限一起使用，
