when i call the share function it opens the device share dialog, then i select bluetooth, then slelect the target device, i it show a "sending file to ..." msg, the i got "file not sent" msg.
if i choose gmail for example, then i can fill the to, title and message fields, but after sending the email there's no attachment with it.
as i said before the problem is with apk files, if i change the ext to zip everything works fine.
