説明
I would like the Android/Java/JNI bindings to support file descriptors. Currently, they only support paths.
I am using Android's SAF (the OS's graphical file picker) to open the model and scorer files. It avoids asking for invasive permissions but returns a file descriptor instead of a path. On Android 10, I could just convert the file descriptor into a path using the expression "/proc/self/fd/" + fd. After updating to Android 11, this fails with a permission denied error. A workaround might be to request for access to the entire internal storage, but this is not ideal for privacy reasons.
I heard that dup works while fopen doesn't. This leads to two possible solutions:
- Add another constructor that accepts an
intto use as a file descriptor, and pass that all the way into native code - Have the existing constructor detect whether the path starts with
/proc/self/fd/, and if it does, use the existing file descriptor instead of opening a file
