Access PDF file in assets folder on android

Question

I have seen many question about accessing files in assets folder but can't seem to get a solid answer. I'm working on a application that would extract a text from PDF file thus I'm using iText Library to do that but my problem here is the file pathing of PDF.

I have tried using assetManager and assetManager opens that file but i think iText needs the file path so it can open the file by itself, i am not sure but that is my theory.

PdfReader reader = new PdfReader(<String PDF-file>);

then How do I access the file under assets folder using iText? if it is not possible is there a way to do that?

Answer 1

Here is sample code to get asset directory for file and use it for pdfreader.

code:

File f = FileUtils.fileFromAsset(this, "filename.pdf");

PdfReader pdfReader = new PdfReader(f.getPath());

Answer 2

You can get an InputStream object like this

AssetManager am = activity.getAssets();
InputStream is = am.open("test.txt");

and then use this constructor

public PdfReader(InputStream is)
          throws IOException
