Hello,
i am wrapping PDFBox for Android
Internally the Library is using this class to load Resources at appstart.
an example use of this class can be found in different locations inside the code...
One example
But when i try to call
from within my wrapper i get an Exception
My guess is that the Android AssetManager isn´t used at all when running from B4A.
Can this class be rewritten to work with B4A. Problem is that i need to add the adapted class in AS and i´m not sure how to add a reference to any B4X Library.
I am doing a wrapper for this Project:
github.com

One example
Java:
protected InputStream getExternalCMap(String name) throws IOException
{
if (PDFBoxResourceLoader.isReady())
{
return new BufferedInputStream(PDFBoxResourceLoader.getStream("com/tom_roush/fontbox/resources/cmap/" + name));
}
InputStream resourceAsStream = getClass().getResourceAsStream("/com/tom_roush/fontbox/resources/cmap/" + name);
if (resourceAsStream == null)
{
throw new IOException("Error: Could not find referenced cmap stream " + name);
}
return new BufferedInputStream(resourceAsStream);
}But when i try to call
Java:
PDFBoxResourceLoader.init(ba.applicationContext);My guess is that the Android AssetManager isn´t used at all when running from B4A.
Can this class be rewritten to work with B4A. Problem is that i need to add the adapted class in AS and i´m not sure how to add a reference to any B4X Library.
