附件未添加到电子邮件意向

问题描述：

我想添加一些照片文件到电子邮件意向。意图正常开始。附件未添加到电子邮件意向

问题：附件没有显示，例如，在GMail应用程序中。我没有收到任何错误消息。哪里可能是问题？

我改变了我的代码以及post中的建议，但我的代码似乎仍然不起作用。

我从照片对象收到的文件路径：file:///storage/emulated/0/Pictures/SMSCloudImages/IMG_20161127_121011.jpg 它应该是正确的路径，因为我可以在图库中显示图像。

Uri uri = Uri.parse("mailto:" + "[email protected]") 
       .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);

这是我使用的代码：

//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 ="[email protected]"; //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 :"));

记住正确的权限添加到Android清单（读写）：

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" /> 
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
