Question

我正在尝试创建一个pdf并通过电子邮件发送。现在我已经成功完成了pdf生成。当我尝试将pdf附加到邮件并发送时，我收到错误。

我这样想：

private void sendMail(Uri URI) {
        try {
            // Uri URI = null;

            String email = emailFromDB;

            String subject = "Report For the day " + getDateTime();

            String message = "Report For the day " + getDateTime();

            final Intent emailIntent = new Intent(android.content.Intent.ACTION_SEND);
            emailIntent.setType("application/pdf");
            emailIntent.putExtra(android.content.Intent.EXTRA_EMAIL,new String[] { email });
            emailIntent.putExtra(android.content.Intent.EXTRA_SUBJECT,subject);

            if (URI != null) {
                emailIntent.putExtra(Intent.EXTRA_STREAM, URI);
            }

            emailIntent.putExtra(android.content.Intent.EXTRA_TEXT, message);
            emailIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
            this.startActivity(Intent.createChooser(emailIntent,"Sending email..."));

        } catch (Throwable t) {

            Toast.makeText(this,

            "Request failed try again: " + t.toString(),

            Toast.LENGTH_LONG).show();

        }

    }

当我尝试发送时，我得到了这个错误。

我在这里得到FileNotFoundException错误。但我在这个位置有pdf。（/mnt/sdcard/MyMenu/2015-05-07 22-50-39-Report.pdf）

请告诉我错误的地方。

Answer 1

所以Finlay我得到了解决方案（由@CommonsWare提供的提示）..

sendMail(Uri.fromFile(emailFilePath));

发送电子邮件方法： -

private void sendMail(Uri URI) {
        try {

            String email = emailFromDB;

            String subject = "Report For the day " + getDateTime();

            String message = "Report For the day " + getDateTime();

            final Intent emailIntent = new Intent(android.content.Intent.ACTION_SEND);
            emailIntent.setType("application/pdf");
            emailIntent.putExtra(android.content.Intent.EXTRA_EMAIL,new String[] { email });
            emailIntent.putExtra(android.content.Intent.EXTRA_SUBJECT,subject);

            if (URI != null) {
                emailIntent.putExtra(Intent.EXTRA_STREAM, URI);
            }

            emailIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
            this.startActivity(Intent.createChooser(emailIntent,"Sending email..."));

        } catch (Throwable t) {

            Toast.makeText(this,

            "Request failed try again: " + t.toString(),

            Toast.LENGTH_LONG).show();

        }

    }

此处我删除了emailIntent.putExtra(android.content.Intent.EXTRA_TEXT, message);并获取了Uri.fromFile(emailFilePath)之类的URI。这解决了我的问题。感谢@CommonnsWare .. !!!
