我正在创建一个具有“导出”功能的应用程序，它将用户的数据转换为 CSV 文件，并允许用户将其作为附件发送给某人（可能是他们自己）。

CSV 文件创建成功，但是当我尝试发送电子邮件时，我遇到了问题。该设备看起来要发送带有适当附件的电子邮件，但是当收到电子邮件时......根本没有附件......

这是我用来发送电子邮件的代码：

final Intent email = new Intent(android.content.Intent.ACTION_SEND);

  email.setType("text/html");
  email.putExtra(android.content.Intent.EXTRA_SUBJECT, getString(R.string.email_subject));
  email.putExtra(android.content.Intent.EXTRA_TEXT, Html.fromHtml(getString(R.string.email_1)));

  email.putExtra(Intent.EXTRA_STREAM, Uri.parse("file:///" + getString(R.string.csv_title)));


  startActivity(Intent.createChooser(email, "Send mail..."));

需要文件的正确路径，如果在 SD 卡上，则...

sendIntent.putExtra(Intent.EXTRA_STREAM, Uri.parse 
("file://"+Environment.getExternalStorageDirectory()+getString(R.string.csv_title)"));

在此处查找有关设置适当文件路径的其他信息

GMail app accepts file:// Uris only if they are on the sdcard... and on an android 1.6 device I had even an issue with it accepting only file://sdcard/* Uris whereas the real external storage of this specific device is on another path.

Anyway, I have a real better behavior with attachments since I provide them through a ContentProvider.
