                    File newFile = new File(s);
                    Uri contentUri = FileProvider.getUriForFile(this,  "com.Jubilant.wifiproject", newFile);

Answer 1

FileProvider 标准无法提供来自可移动微型 SD 卡的文件。

有时添加

<root name="root" path="." />

到您的 file_paths.xml 文件。

在其他情况下，编写您自己的文件提供程序扩展 ContentProvider。
