android - 无法以编程方式在android中发送带有多个附件的电子邮件

Question

我无法使用 Intent 选择器在 Android 中发送包含多个附件的电子邮件。从选择器中选择 gmail 后，抛出 Unfortunately gmail has stopped 错误。我不知道我犯了什么错误。谁能帮帮我？

 final Intent ei = new Intent(Intent.ACTION_SEND_MULTIPLE);
                                        ei.setType("plain/text");
                                        ei.putExtra(Intent.EXTRA_EMAIL, new String[] {"ademo@gmail.com"});
                                        ei.putExtra(Intent.EXTRA_SUBJECT, "SFC App Equiry");
                                        ei.putExtra(android.content.Intent.EXTRA_TEXT,Html.fromHtml("<b>"+"Packing Date"+"</b>&nbsp;"+pdate+"<br><b>"+"Shifting Date"+"</b>&nbsp;"+sdate+"<br><b>"+"Delivery Date"+"</b>&nbsp;"+ddate+"<br><b>"+"Source city"+"</b>&nbsp;"+scity+"<br><b>"+"Destination City"+"</b>&nbsp;"+dcity+"<br><b>"+"Source Property Type"+"</b>&nbsp;"+stprop+"<br><b>"+"Destination Property Type"+"</b>&nbsp;"+dtprop));

                                    ArrayList<Uri> uris = new ArrayList<Uri>();

                                    //uris.parse("file://sdcard/Images/20140812_130215.jpg");
                                    //uris.add("file://sdcard/Images/20140812_130227.jpg");

                                    File fileIn = new File(ppath);
                                    File fileIn1 = new File(ppath1);
                                    File fileIn2 = new File(ppath2);
                                    File fileIn3 = new File(ppath3);
                                    File fileIn4 = new File(ppath4);
                                    File fileIn5 = new File(ppath5);
                                    File fileIn6 = new File(ppath6);

                                    Uri u = Uri.fromFile(fileIn);
                                    Uri u1 = Uri.fromFile(fileIn1);
                                    Uri u2 = Uri.fromFile(fileIn2);
                                    Uri u3 = Uri.fromFile(fileIn3);
                                    Uri u4 = Uri.fromFile(fileIn4);
                                    Uri u5 = Uri.fromFile(fileIn5);
                                    Uri u6 = Uri.fromFile(fileIn6);

                                    uris.add(u);
                                    uris.add(u1);
                                    uris.add(u2);
                                    uris.add(u3);
                                    uris.add(u4);
                                    uris.add(u5);
                                    uris.add(u6);



                                    ei.putParcelableArrayListExtra(Intent.EXTRA_STREAM, uris);
                                    startActivityForResult(Intent.createChooser(ei, "Sending multiple attachment"), 12345);

您可以使用以下代码通过邮件发送多个附件:

public boolean sendEmailWithMultipleAttachments(Context context,
                                                        String[] emailTo, String[] emailCC, String[] emailBCC,
                                                        String subject, String emailBody, List filePaths) throws ActivityNotFoundException {

            final Intent emailIntent =
                    new Intent(android.content.Intent.ACTION_SEND_MULTIPLE);
            emailIntent.setType("message/rfc822");
            emailIntent.putExtra(android.content.Intent.EXTRA_EMAIL, emailTo);
            emailIntent.putExtra(android.content.Intent.EXTRA_CC, emailCC);
            emailIntent.putExtra(android.content.Intent.EXTRA_BCC, emailBCC);
            emailIntent.putExtra(Intent.EXTRA_SUBJECT, subject);
            ArrayList<String> extra_text = new ArrayList<String>(); 
            extra_text.add("Your text here"); 
            ei.putStringArrayListExtra(Intent.EXTRA_TEXT, extra_text);

            if (filePaths != null) {
                // has to be an ArrayList
                ArrayList uris = new ArrayList();
                // convert from paths to Android friendly Parcelable Uri's
                for (String file : filePaths) {
                    File fileIn = new File(file);
                    if (fileIn.exists()) {
                        Uri u = Uri.fromFile(fileIn);
                        uris.add(u);
                    }
                }
                emailIntent.putParcelableArrayListExtra
                        (Intent.EXTRA_STREAM, uris);
            }
            context.startActivity(Intent.createChooser(emailIntent, "Sent mail"));
            return true;
        }
