There may be file access interception going on and FileManager isn't
Android aware.
You can also try RDFDataMgr.
Another possible problem is bad Jena system initialization because
AdapterFileManager searches with various configured mechanisms.
You could open the file as a FileInputStream, going to the native
android IO library, and read from that.

Does the file really exist? And does it matter it is a windows format
file name?
If you are using Androjena, which is a 3rd part port for Jena, not
from
the Apache Jena project, it is based on a quite old version of Jena.
If that file exists, and if you use the windwos file synatx, try:
"file:///C:/Users/Toshiba/AndroidStudioProjects/MyApplication/app/sampledata/MallOntology.owl"
