推荐答案

PDFBox的使用Java AWT和Swing，即使是对非UI的任务，我试图删除引用，但也有很多文件，我被删除过太多的东西

PDFBox uses java awt and swing, even for non UI tasks, I've tried to remove references but there are a lot of files, and I was removing too much stuff

我刚刚测试过PDFjet http://pdfjet.com/os/edition.html 它采用BSD授权（再加上商业版有更多的功能），在此示例code（从Example_03.java撕开）我能为JPEG转换为PDF

I've just tested PDFjet http://pdfjet.com/os/edition.html it's bsd licensed (plus commercial version with more features), with this sample code (ripped from Example_03.java) I was able to convert a jpeg to a pdf

    FileOutputStream fos = null;
    try
    {
        fos = new FileOutputStream("/sdcard/sample.pdf");
        PDF pdf = new PDF(fos);
        InputStream f = getApplicationContext().getAssets().open("img0.jpg"); 
        Image image = new Image(pdf, f, ImageType.JPEG);
        Page page = new Page(pdf, A4.PORTRAIT);
        image.setPosition(0, 0);
        image.drawOn(page);
        pdf.flush();
        fos.close();
    } catch (Exception e)
    {
        e.printStackTrace();
    }
