我正在使用此代码在android中生成pdf文件,但它给了我找不到文件异常
I am using this code to generate pdf file in android but it gives me "File not found exception"
try { OutputStream file = new FileOutputStream(new File("D:\\Test.pdf")); Document document = new Document(); // PdfWriter.getInstance(document, new FileOutputStream(FILE)); PdfWriter.getInstance(document, file); document.open(); addMetaData(document); addTitlePage(document); addContent(document); //createImage(); document.close(); } catch (Exception e) { e.printStackTrace(); }:
PdfWriter.getInstance(document, file);它表示Java.io.FileNotFOundException。我必须创建新文件然后为什么打开一个甚至没有生成的文件?这段代码出了什么问题?

推荐答案我不认为D:\是android中的有效文件位置
