以編程方式無法在多個附件中發送電子郵件

Question

我無法使用Intent選擇器在Android中使用多個附件發送電子郵件。從選擇器中選擇gmail後，它拋出不幸的是gmail已停止錯誤。我不會犯我犯過什麼錯誤。誰能幫我？

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); 

我的堆棧跟蹤是：

Answer 1

我沒有改變任何代碼。但今天運行後，它的工作完美。不知道哪一個錯誤或正確。無論如何，現在它對我來說工作得很好，我發佈了相同的代碼。謝謝Alok Nair提供這樣的幫助。

Answer 2

您可以用下面的代碼發送郵件上多個附件：

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; 
     }
