A "backport" of the java.nio.file packages, primarily intended for Android (safs-android), but its core package (safs-core) may work on any Java 6+ Unix/Linux JVM.
Some parts are unsupported or incomplete, mostly related to symlinks and storage volumes.
Android didn't get java.nio.file support until Android 8, so it will probably be quite some time before apps
supporting older Android can use it. When that time finally come it should be easy to switch over, simply changing import.
The major feature of safs-android is its ability to seamlessly use the Android 5.1+
Storage Access Framework (SAF)
when accessing secondary external storage volumes, i.e. removable SD cards, once granted access by the user using an
ACTION_OPEN_DOCUMENT_TREE intent.
- Use a mature file-system API, i.e. java.nio.file.Files.
- A unified API for accessing files on both internal, primary and secondary storage, from Android 4 through 9. Q support is planned.
- Makes it easier to "port" existing, or implement new,
FileSystemProvider, e.g. for accessing zip files, FTP, Google Drive. - A layer for working around Android issues.
For more information, see safs-android.
The core package uses the java.io.File to access the file-system.
Only support OS'es using / as path separator, e.g. Unix/Linux.
