【问题描述】：

我想将一些照片文件添加到电子邮件意图中。意图正在正常启动。

问题：附件未显示，例如在 GMail 应用程序中。我没有收到任何错误消息。问题可能出在哪里？

我已经根据post 中的建议更改了我的代码，但我的代码似乎仍然无法正常工作。

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:" + "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);

【解决方案1】：

记得给android manifest添加正确的权限（读写）：

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

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 ="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 :"));
