发送XML文件作为与Android附件

问题描述

我尝试让我的Andr​​oid应用程序发送一封电子邮件，XML文件作为attachement。所有的工作除了事实，我收到的XML文件是空的罚款。我检查，以确保该文件不是空的我的手机上......

im trying to make my android application send an email with an xml file as attachement. All is working fine except for the fact that the xml file I receive is empty. I checked to make sure the file isn't empty on my phone...

下面是code我用它来发送邮件：

Here is the code I use to send the mail:

Intent mailIntent = new Intent(Intent.ACTION_SEND);
        mailIntent.setType("text/Message");
        mailIntent.putExtra(Intent.EXTRA_EMAIL, new String[] {"[email protected]"});
        mailIntent.putExtra(Intent.EXTRA_SUBJECT, "MySubject");
        mailIntent.putExtra(Intent.EXTRA_STREAM, Uri.parse("file///sdcard/rapport.xml"));
        startActivity(Intent.createChooser(mailIntent, "Send it out!"));

日Thnx提前！

Thnx in advance!

推荐答案

我想可能是你的文件协议，声明在那里。你可以可尝试的 Uri.fromFile 的，或者只是用文件：///（你似乎缺少冒号，除非那这里只是一个错字）。

I think it might be your file protocol declaration there. You could either try Uri.fromFile, or maybe just use "file:///" (yours appears to be missing the colon, unless that's just a typo here).

的)

另外，我的是接近你的，但是这是我如何在过去做了它（和它似乎工作）：

Also, mine is close to yours, but this is how I have done it in the past (and it seems to work):

File f = new File("path_to_file");
   if (f.exists() && f.canRead()) {
      Intent sendIntent = new Intent(Intent.ACTION_SEND);
      sendIntent.setType("text/plain");
      sendIntent.putExtra(Intent.EXTRA_STREAM, Uri.parse("file://" +
         f.getAbsolutePath()));
      sendIntent.putExtra(Intent.EXTRA_SUBJECT, "SUBJECT");
      sendIntent.putExtra(Intent.EXTRA_TEXT, "BODY");
      startActivity(Intent.createChooser(sendIntent, "Email:"));
   } else {
     Toast.makeText(Main.this, getString(R.string.fileNotExistBlah),
        Toast.LENGTH_LONG).show();
   }
