Android 打开失败：EACCES（权限被拒绝）

在尝试保存图像时，Galaxy J5（Android 6.0）中出现以下错误：

java.io.FileNotFoundException: /storage/FA49-E5D3/DCIM/Camera/20170311_140435.jpg: open failed: EACCES (Permission denied)

我有以下权限：

<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

您正在尝试在micro SD卡上写入文件。但如今，这些应用程序都是只读的。只有系统摄像头应用程序可以在SD上的DCIM文件夹中写入

查看GetExternalFileDirs（）返回的第二项。您的应用程序可以写入SD卡上特定于应用程序的目录。

显示您正在设置该路径吗？公共字符串getOriginalImagePath（）{String[]projection={MediaStore.Images.Media.DATA}；Cursor Cursor=this.managedQuery（MediaStore.Images.Media.EXTERNAL_CONTENT_URI，projection，null，null）；int column_index_data=cursor.getColumnIndexOrThrow（MediaStore.Images.Media.data）；cursor.moveToLast（）；返回cursor.getString（column_index_data）；}
