I am developing 2 apps:
App #1 will contain some bittorrent .torrent files in it's DirInternal.
App #2 is a bittorrent client that needs to open one or more of the other app's .torrent files.
In app #1 i'm creating an Intent with the Uri of the .torrent file as it's data and then broadcasting this Intent.
App #2 receives the broadcast Intent and now i need to open the .torrent file.
This is the Service in app #2 that receives the broadcast:
The log shows:
FYI app 1 is a 'file provider', it's manifest contains:
And the code used to create and broadcast the Intent:
(It's just a modified version of the FileProvider example).
How can app #2 open the .torrent file in app #1's DirInternal?
Stripping "file://" from the uri string value and trying to access "/data/data/b4a.example.deleteme/files/torrent-files/myfile.torrent" fails with a permission error (as to be expected).
