Hello, I am trying to download a map for offline use but am running into trouble with generating the parameters as per this error I get (I have included my code also):

E/CRGdb: Error generating geodatabase parameters : com.esri.arcgisruntime.ArcGISRuntimeException: Invalid response
*******I have commented out portions of the code because it was returning this error each time and I wanted to know when it began (apparently it was after this line:
GenerateGeodatabaseParameters parameters = defaultParameters.get();
