Solution 1 :
FYI on Android >= 11 copying to the Downloads folder has no utility.
Other apps can’t read a file in Downloads even if they have READ_EXTERNAL_STORAGE. The traditional use of Downloads as a pool of shared files no longer works. Since only your app can read the file there is no point in putting it there. The idea is Downloads is only a cache for files your app downloaded.
Problem :
I am trying to inform the download application that files have appeared in the Downloads folder, but after copying the file to this folder and using the code below, the file does not appear. For android version below 10 I get an error: jnius.jnius.JavaException: No methods matching your arguments, requested: (<java.lang.String at 0x796d9637c0 jclass=java/lang/String jself=<LocalRef obj=0x6516 at 0x796d9c6e10>>, <java.lang.String at 0x796d9637c0 jclass=java/lang/String jself=<LocalRef obj=0x6516 at 0x796d9c6e10>>, True, <java.lang.String at 0x796d963950 jclass=java/lang/String jself=<LocalRef obj=0x6502 at 0x796d957870>>, '/storage/emulated/0/Download/surface.stl', <java.lang.Integer at 0x796d963270 jclass=java/lang/Integer jself=<LocalRef obj=0x6522 at 0x796d957850>>, True), available: ['(Ljava/lang/String;Ljava/lang/String;ZLjava/lang/String;Ljava/lang/String;JZ)J', '(Ljava/lang/String;Ljava/lang/String;ZLjava/lang/String;Ljava/lang/String;JZLandroid/net/Uri;Landroid/net/Uri;)J']. I would some thing like MediaScannerConnection.scanFile.
