Also, some code cleanup in SafTabFragment. * don't run FFprobe after video playback * ACTION_GET_CONTENT is better than ACTION_OPEN_DOCUMENT: it gives us more options to choose. * add closeParcelFileDescriptor to fix working with Google Drive keep the temp files open, we must keep the ParcelFileDecriptor until the fd is closed	2020-09-21 22:29:22 +01:00
