Hello,
I have been generated rdf/xml file from Pretege.
I am trying to load it in android studio by using the following code:
Model m =
FileManager.get().loadModel("C:\\Users\\Toshiba\\AndroidStudioProjects\\MyApplication\\app\\sampledata\\MallOntology.owl")
;
but I always get that the File Not exist.
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"
I am trying to insert data fetched from Facebook login the source code is :
Model m =
FileManager.get().loadModel("C:\\Users\\Toshiba\\AndroidStudioProjects\\MyApplication\\app\\sampledata\\MallOntology.owl")
