Describe what you expected to happen:

The sync executes successfully

What version of Keepass2Android are you using?

1.14-r4

Which version of Android are you on?

16

Start with keepass2android.javafilestorage.WebDavStorage.UploadFile at the failing stack-trace lines and trace the remote database sync path that produces the unexpected end-of-stream error. Reproduce the upload against a remote WebDAV database and determine the conditions that trigger the EOFException; done means the sync succeeds in that case with a regression check if the project has coverage for this path.
