Question

How to attach multiple files in email in android?
Is there any permission required for multiple files attachment to an intent?
I am trying with putParcelableArrayListExtra(Intent.EXTRA_STREAM, ArrayList uriList) method but still in doubt whether Uri class is <? extends Parcelable> or not. I am not able to attach any file to email.

This is my code ::

Intent sendIntent = new Intent(Intent.ACTION_SEND_MULTIPLE);
sendIntent.setType("plain/text");
sendIntent.putExtra(Intent.EXTRA_EMAIL, new String[] {"[e-mail]"});
sendIntent.putExtra(Intent.EXTRA_SUBJECT, "Accident Capture");
sendIntent.putExtra(Intent.EXTRA_TEXT, emailBody);

ArrayList<Uri> uriList = getUriListForImages();
sendIntent.putParcelableArrayListExtra(Intent.EXTRA_STREAM, uriList);
Log.d(TAG, "Size of the ArrayList :: " +uriList.size());
FormHolderActivity.this.startActivity(Intent.createChooser(sendIntent, "Email:"));

and getUriListForImages() this method is defined as bellow —–

private ArrayList<Uri> getUriListForImages()  {

    ArrayList<Uri> uriList = new ArrayList<Uri>();
    String imageDirectoryPath =  Environment.getExternalStorageDirectory().getAbsolutePath()+ "/accident/";
    File imageDirectory = new File(imageDirectoryPath);
    String[] fileList = imageDirectory.list();

    if(fileList.length != 0) {
        for(int i=0; i<fileList.length; i++)
        {
            String file = "file://" + imageDirectoryPath + fileList[i];
            Log.d(TAG, "File name for Uri :: " + file);
            Uri uriFile = Uri.parse(file);
            uriList.add(uriFile);
            Log.d(TAG, "Image File for Uri :: " +(file));

        }
    }
    return uriList;
}

To, subject and body of the email is coming and I have images in the accident folder in sdcard (I am using 2.1 API level 7) but nothing is attaching even there is also no exception in logcat.Arraylist is also ok(means length OK and name of the files are ok too). Can anyone help me to solve this problem?

Answer 1

After 1 day work finally I am able to attach multiple image files from \sdcard\accident\ folder to email client. For attaching multiple files I had to add the images to the ContentResolver which is responsible for gallery images provider.
Here is the Complete Code —

Intent sendIntent = new Intent(Intent.ACTION_SEND_MULTIPLE);
sendIntent.setType("plain/text");
sendIntent.putExtra(Intent.EXTRA_EMAIL, new String[] {"[e-mail]"});
sendIntent.putExtra(Intent.EXTRA_SUBJECT, "Accident Capture");
sendIntent.putExtra(Intent.EXTRA_TEXT, emailBody);

ArrayList<Uri> uriList = getUriListForImages();
sendIntent.putParcelableArrayListExtra(Intent.EXTRA_STREAM, uriList);
Log.d(TAG, "Size of the ArrayList :: " +uriList.size());
FormHolderActivity.this.startActivity(Intent.createChooser(sendIntent, "Email:"));

So there is no change in the First Section of Code — But Change is in getUriListForImages() method which is as follows—

    private ArrayList<Uri> getUriListForImages() throws Exception {
                ArrayList<Uri> myList = new ArrayList<Uri>();
                String imageDirectoryPath = Environment.getExternalStorageDirectory().getAbsolutePath()+ "/accident/";
                File imageDirectory = new File(imageDirectoryPath);
                String[] fileList = imageDirectory.list();
                if(fileList.length != 0) {
                    for(int i=0; i<fileList.length; i++)
                    {   
                        try 
                        {   
                            ContentValues values = new ContentValues(7);
                            values.put(Images.Media.TITLE, fileList[i]);
                            values.put(Images.Media.DISPLAY_NAME, fileList[i]);
                            values.put(Images.Media.DATE_TAKEN, new Date().getTime());
                            values.put(Images.Media.MIME_TYPE, "image/jpeg");
                            values.put(Images.ImageColumns.BUCKET_ID, imageDirectoryPath.hashCode());
                            values.put(Images.ImageColumns.BUCKET_DISPLAY_NAME, fileList[i]);
                            values.put("_data", imageDirectoryPath + fileList[i]);
                            ContentResolver contentResolver = getApplicationContext().getContentResolver();
                            Uri uri = contentResolver.insert(Images.Media.EXTERNAL_CONTENT_URI, values);
                            myList.add(uri);
                        } catch (Exception e) {
                            e.printStackTrace();
                        }
                    }
                }
                return myList;
            } 

This is working fine and I am able to attach multiple image files to emulator default email client and send them successfully .
