我的应用使用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。当我尝试附加该文件时,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。
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();
}
尝试附加文件并发送电子邮件:
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..."));
}
其中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)。

我遇到了类似的问题。上面CommonsWare的评论解决了它。!
使用Uri.fromFile()方法创建一个File对象并生成一个Uri。
.row1{
width: 100%;
}
.row1 span{
background-color: #ff0000;
padding:10px 20px 10px 20px;
display: inline-block;
vertical-align: top;
color:white;
width: 14%;
}
.lista{
display: inline-block;
vertical-align: top;
width:71%;
}
.row1 ul{
display: inline-block;
margin-top: 13px;
}
.row1 ul li{
display: inline-block;
vertical-align: top;
font-size: 0.7em;
margin-left: 1px;
}
.row1 ul li a {
color:#333;
}
.row1 ul li:before{
content:'|';
padding-right: 5px;
padding-left: -2px;
}
.row1 ul li:first-child:before{
content:none !important;
}
