Problem
When calling termux-storage-get, nothing happens. When displaying traces using logcat, an error appears, related to FLAG_ACTIVITY_NEW_TASK.

Steps to reproduce
On a fully patched Samsung s8 (stock and not rooted), after installing the needed termux components, this is systematic.

Expected behavior
Should work OK : display a file selector and copy the selected file to the given destination.

Additional information
Post output of command termux-info.

(I copied as much as possible from termux terminal)

Something strange (maybe not related) : the Termux:API has no storage permission that I can give him, in app properties.
