附件未添加到電子郵件意向

Question

我想添加一些照片文件到電子郵件意向。 意圖正常開始。

問題：附件沒有顯示，例如，在GMail應用程序中。我沒有收到任何錯誤消息。 哪裏可能是問題？

我改變了我的代碼以及post中的建議，但我的代碼似乎仍然不起作用。

我從照片對象收到的文件路徑：file:///storage/emulated/0/Pictures/SMSCloudImages/IMG_20161127_121011.jpg 它應該是正確的路徑，因爲我可以在圖庫中顯示圖像。

Uri uri = Uri.parse("mailto:" + "someone@mail.com") 
       .buildUpon() 
       .appendQueryParameter("subject", subject) 
       .appendQueryParameter("body", body) 
       .build(); 

     List<Photo> photoList = new ArrayList<>(); 
     photoList.addAll(databaseHandler.getPhotos(qReport.getId())); 

     Intent emailIntent = new Intent(Intent.ACTION_SENDTO, uri); 

     Intent intentPick = new Intent(); 
     intentPick.setAction(Intent.ACTION_PICK_ACTIVITY); 
     intentPick.putExtra(Intent.EXTRA_TITLE, getResources().getString(R.string.q_report_launch_mail_text)); 
     intentPick.putExtra(Intent.EXTRA_INTENT, emailIntent); 

     for (Photo photo: photoList) { 
      intentPick.putExtra(Intent.EXTRA_STREAM, Uri.parse(photo.getName())); 
     } 

     this.startActivityForResult(intentPick, REQUEST_CODE_MY_PICK);

這是我使用的代碼：

//how hany picture you want the user to upload 
private static final int SELECT_PICTURE = 1; 

public void grabImg(){ 
    Intent intent = new Intent(); 
    intent.setType("image/*"); 
    intent.setAction(Intent.ACTION_GET_CONTENT); 
    startActivityForResult(Intent.createChooser(intent, 
      "Select Picture"), SELECT_PICTURE); 
} 

Uri uri = null; 

protected void onActivityResult(int requestCode, int resultCode, Intent imageReturnedIntent) { 
    super.onActivityResult(requestCode, resultCode, imageReturnedIntent); 
     if(resultCode == RESULT_OK){ 
      Uri selectedImage = imageReturnedIntent.getData(); 
      uri = selectedImage; 

     } 
} 

//This is triggered on a button click 

String subject = Suggest.getText().toString(); 
      String rating = String.valueOf(RateBar.getRating()); 
      String to ="xxxxx@mail.com"; //destination 
      String message = UserInput.getText().toString(); 
      String body = message; 
      Intent email = new Intent(Intent.ACTION_SEND); 
      email.putExtra(Intent.EXTRA_EMAIL, new String[]{to}); 
      email.putExtra(Intent.EXTRA_SUBJECT, subject); 
      email.putExtra(Intent.EXTRA_TEXT, body); 
      email.putExtra(Intent.EXTRA_STREAM, uri); 
      email.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION); 
      //need this to prompts email client only 
      email.setType("message/rfc822"); 

      startActivity(Intent.createChooser(email, "Choose an Email client :"));
