推荐答案

如果您尝试通过电子邮件发送文件，请确保文件位于公共可访问位置，并且告诉您该文件是您想要的文件发送.使用此代码作为示例.

If you are trying to send files with email, make sure that they are on a public accessible location and that you tell it that it is a file you want to send. Use this code as an example.

Intent emailIntent = new Intent(android.content.Intent.ACTION_SEND);
emailIntent.setType("message/rfc822").putExtra(Intent.EXTRA_EMAIL, new String[]{"[e-mail]"}).putExtra(android.content.Intent.EXTRA_SUBJECT, "Mail subject").putExtra(android.content.Intent.EXTRA_TEXT, "lalalala");
String targetFilePath = Environment.getExternalStorageDirectory().getPath() + File.separator + "tmp" + File.separator + "test.txt";
Uri attachmentUri = Uri.parse(targetFilePath);
emailIntent.putExtra(android.content.Intent.EXTRA_STREAM, Uri.parse("file://" + attachmentUri));
