代码：

public void openFile(File file, String password) throws IOException { 
     // first open the file for random access 
     RandomAccessFile raf = new RandomAccessFile(file, "r"); 

     // extract a file channel 
     FileChannel channel = raf.getChannel(); 

     // now memory-map a byte-buffer 
     ByteBuffer bb = 
       ByteBuffer.NEW(channel.map(FileChannel.MapMode.READ_ONLY, 0, channel.size())); 
     // create a PDFFile from the data 
     if (password == null) 
      mPdfFile = new PDFFile(bb); 
     else 
      mPdfFile = new PDFFile(bb, new PDFPassword(password)); 

     mGraphView.showText("CLHed:" + mPdfFile.getNumPages()); 
    }

我收到路径：

我无法访问罐子，因此我可以检查哪条线路导致麻烦。谁能帮我？有没有人面临同样的问题？谢谢

你可以发布的PDF阅读代码，错误是说这可能不是一个PDF文件，你有没有注意到 – insomniac

我编辑我的问题，你能再请检查吗？ –

你正在试图创建一个PDF或试图阅读它？ – insomniac

错误的PDF文件的路径。只是调试
