よくわからないエラーが出ます。私がやろうとしているのは、pdfからテキストを抽出することだけです。私は droidText を使用しています ( http://code.google.com/p/droidtext/ ) これはコードです:
public void parsePdf(URL pdf) throws IOException {
PdfReader reader = new PdfReader(pdf.openStream());
PdfTextExtractor pdfEx = new PdfTextExtractor(reader);
for(i=1; i <= reader.getNumberOfPages(); i++){
Scanner scanner = new Scanner(pdfEx.getTextFromPage(i));
while(scanner.hasNextLine()){
paragraphs.add(scanner.nextLine());
}
}
}
これはlogcatです:

私のコードの何が問題なのか誰か知っていますか?
