如何在Android 10中创建公用文件夹/文件 [英] How to create a public folder/file in Android 10
问题描述
Android Api 29在文件和文件夹方面有很大的变化.到目前为止，我还没有找到在公共可见的内部存储中创建文件夹的方法.我创建的每个文件夹只能由我的应用查看.
Android Api 29 has big changes regarding files and folders. I have not found a way so far to create a folder in the internal storage that is public visible. Every folder I create can be seen by my app only.
我编写了一个应用程序，该应用程序创建了应由其他应用程序(例如，Total Commander)将其复制到目标位置的数据文件.在激活Api 29之前，一切正常.我的某些客户端确实使用像素电话，而他们使用的是Android 10.
I write an app that creates data files that shall be picked up by other apps, for instance the Total Commander to copy them to a destination. Everything worked fine until I activated Api 29. Some of my clients DO use pixel phones and they use Android 10.

已弃用:
Environment.getExternalStorageDirectory();
Environment.getExternalStoragePublicDirectory(type);
当我使用
File root = context.getExternalFilesDir(null);
创建的文件只能由我的应用查看.如何实现在Android 10之前有效的行为?
The created files can only be seen by my app. How can I achieve the behavior that was valid before Android 10?
提前谢谢.

如果用户选择了您放置在该目录中的文档，则任何使用Storage Access Framework的应用程序(例如 ACTION_OPEN_DOCUMENT )都可以看到它们.
They can be seen by any app that uses the Storage Access Framework (e.g., ACTION_OPEN_DOCUMENT), if the user chooses the document that you place in that directory.

在 Context 上使用 getExternalFilesDir()和相关方法.或者，使用 ACTION_CREATE_DOCUMENT 或 ACTION_OPEN_DOCUMENT_TREE 并使用存储访问框架.无论哪种情况，生成的文档都可以由其他同时使用Storage Access Framework的应用程序使用.
Use getExternalFilesDir() and related methods on Context. Or, use ACTION_CREATE_DOCUMENT or ACTION_OPEN_DOCUMENT_TREE and use the Storage Access Framework. In either case, the resulting documents can be used by other apps that also use the Storage Access Framework.
