What steps will reproduce the problem?
1. Create InputStream from RDF file as an application raw resource
2. Call model.read(is,null);

This isn't an androjena error; seems like android cannot read the raw resource, 
so the xml parser (ExpatParser) fails. From the Android reference 
(http://developer.android.com/reference/android/content/res/Resources.html#openR
awResource(int)):

openRawResource: This can only be used with resources whose value is the name 
of an asset files -- that is, it can be used to open drawable, sound, and raw 
resources; it will fail on string and color resources.

Please try to embed the rdf file as an asset, that is, put it in the assets 
folder in the root of the app project, and open it with:

InputStream fis = getAssets().open("rdf_file_name.rdf");

Let me know if this solves the issue,
bye

If the previous suggestion doesn't work, it could be a problem related to the 
rdf file itself, such as bad form or unrecognized encoding, so please upload 
the rdf file so that i can try to parse it locally.

So, your suggestion did not work unfortunately. Note that the test.rdf passes 
the W3C RDF validator check.

Model model = ModelFactory.createDefaultModel();
InputStream fis = getAssets().open("test.rdf");
model.read(fis,null);

Attached:
- test.rdf
- androjena_log2.txt <- The error using the getAssets() approach

I see from the new logcat that the exception has changed; now the error seems 
to be related to ICU4J not being able to read one of the data files that are 
bundled in icu4j-3.4.5.jar. This never happened before and is very strange, 
I'll do some deeper debugging and get back to you. It would be very helpful if 
you could attach the whole eclipse project, thanks.

Hi.. just following this up.

Did you find anything when you looked into the fact that ICU4J not reading one 
of the data files bundled with icu4j-3.4.5.jar ?
