我的应用程序使用IText库创建了一个PDF文件(模板PDF,表格已填好),然后我想将它附加到一封要发送的电子邮件中。当我尝试附加文件时,会在gmail应用程序中得到错误Can't attach empty file
。也尝试过HTC电子邮件应用程序和触地电子邮件应用程序-两者都不附加任何内容,不会出错。
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();
}
正在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可以的,因为这是用于保存文件的var(我可以在设备和PC上查看)。Gmail日志:

最佳答案
我也面临同样的问题。上面的commonware评论解决了这个问题。
创建一个文件对象,并使用uri.fromfile()方法生成一个URI。
File file = new File(filePath);
Uri uri = Uri.fromFile(file);
