Gmail“无法附加空文件”

提问于

我的应用程序使用iText库创建PDF（带有填写表格的模板PDF），然后我想将其附加到要发送的电子邮件中 . 当我尝试附加文件时，我在Gmail应用中收到错误 Can't attach empty file . 还试过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并且没有错误 .

Creating the 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();
}

Attempting to attach file and send email:

public void sendMail(){
    Intent emailIntent = new Intent(Intent.ACTION_SEND);
    emailIntent .setType("*/*");
    emailIntent .putExtra(Intent.EXTRA_EMAIL, "blah@gmail.com");
    emailIntent .putExtra(Intent.EXTRA_STREAM, Uri.parse(dest));
    emailIntent .putExtra(Intent.EXTRA_SUBJECT, "Subject");
    startActivity(Intent.createChooser(emailIntent, "Send email..."));
}

dest 是相关文件的路径和文件名 . 我知道 dest 中的路径和文件名是正常的，因为这是用于保存文件的var（我可以在设备和PC上查看） .

    我面临着类似的问题 . 上面CommonsWare的评论解决了它 .

    使用Uri.fromFile（）方法创建File对象并生成Uri .

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

    我在使用Android 6的Nexus 5上遇到了同样的问题（相同的代码在我的Nexus 6上使用Android 6），在这里找到解释和工作解决方案：https://stackoverflow.com/a/32982050/534898
