Gmail“无法附加空文件" [英] Gmail "Can't attach empty file"

问题描述

我的应用程序使用iText库(带有已填写表格的模板PDF)创建了PDF，然后我想将其附加到电子邮件中进行发送.尝试附加文件时，我在Gmail应用中收到错误无法附加空文件.还尝试过使用HTC电子邮件应用程序和Touchdown电子邮件应用程序-两者都没有附加任何内容且没有错误.

My app creates a PDF using iText library (template PDF with forms which are filled) and I want to then attach it to an email to send. When I try to attach the file I get the error Can't attach empty file in the Gmail app. Have also tried with the HTC email app and Touchdown email app - both of which just don't attach anything and give no error.

创建PDF:

public void manipulatePdf(String src, String dest) throws IOException, DocumentException {
        PdfReader reader = new PdfReader(src);
        PdfStamper stamper = new PdfStamper(reader, new FileOutputStream(dest));
        AcroFields form = stamper.getAcroFields();

// Fill all PDF forms here (theres quite a few)

        stamper.setFormFlattening(true);
        stamper.close();
        reader.close();
}

尝试附加文件和发送电子邮件:

public void sendMail(){
    Intent emailIntent = new Intent(Intent.ACTION_SEND);
    emailIntent .setType("*/*");
    emailIntent .putExtra(Intent.EXTRA_EMAIL, "[e-mail]");
    emailIntent .putExtra(Intent.EXTRA_STREAM, Uri.parse(dest));
    emailIntent .putExtra(Intent.EXTRA_SUBJECT, "Subject");
    startActivity(Intent.createChooser(emailIntent, "Send email..."));
}

其中 dest 是所讨论文件的路径和文件名.我知道 dest 中的路径和文件名都可以，因为这是用于保存文件的var(我可以在设备和PC上正常查看).

Where dest is the path and filename of the file in question. I know the path and filename in dest are ok as this is the var used to save the file (which I can view fine on both the device and on a PC).

推荐答案

我遇到了类似的问题.上面的CommonsWare注释解决了！！

I was facing a similar issue. CommonsWare's comment above resolved it.!

创建一个File对象，并使用Uri.fromFile()方法生成一个Uri.

Create a File object and generate a Uri using Uri.fromFile() method.

File file = new File(filePath);
Uri uri = Uri.fromFile(file);
