I was trying to extract the content of a pdf file and display its content in android. I tired the code in java and it worked.But when i am coding it in android, its not displaying anything.I placed the file in assets folder and then used asset manager(not sure its correct) to get the file.But the output is not shown.Also when i debugged the pgm,its showing some error. The code is given below:

AssetManager assetManager =getAssets();

InputStream stream = null;

try {

    stream = (InputStream) assetManager.open("FirstPdf.pdf");

} catch (IOException e) {

    // handle


  PdfReader reader = new PdfReader(stream);

   str=PdfTextExtractor.getTextFromPage(reader, 2);

Error show in debug window:

I would be very grateful if the problem is solved.
