java SecurityException:权限拒绝：读取com。安卓提供者。媒体MediaProvider需要安卓。准许读取外部存储器
我有一个活动，它有一个浏览器按钮，然后是一个imageview，希望用户看到他们上传的内容，但每次选择要“上传”的图像时，我都会犯错误“没有响应”。。。虽然我已将权限放入清单中
错误记录人（logcat）

根据你的日志
因为当应用程序Android版本为6.0时，您必须需要运行时权限
READ_EXTERNAL_STORAGE你可以这样做
或
你可以试试https://github.com/permissions-dispatcher/PermissionsDispatcher
这对你来说会更容易
