Here is the working code which you need:

Firstly save image from Drawable to SD Card here is the code:

try{

Bitmap largeIcon = BitmapFactory.decodeResource(getResources(), R.drawable.bubble_green);

            //replace "R.drawable.bubble_green" with the image resource you want to share from drawable 

            ByteArrayOutputStream bytes = new ByteArrayOutputStream();
            largeIcon.compress(Bitmap.CompressFormat.JPEG, 40, bytes);

            // you can create a new file name "test.jpg" in sdcard folder.
            File f = new File(Environment.getExternalStorageDirectory() + File.separator + "test.jpg");

            f.createNewFile();

            // write the bytes in file
            FileOutputStream fo = new FileOutputStream(f);
            fo.write(bytes.toByteArray());

            // remember close de FileOutput
            fo.close();
        }
        catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }

Then get the saved image from SD card and attach in the email intent like this:

        Intent shareIntent = new Intent(android.content.Intent.ACTION_SEND);
        shareIntent.setType("image/jpeg");

        shareIntent.putExtra(android.content.Intent.EXTRA_SUBJECT, "Hi"); //set your subject
        shareIntent.putExtra(android.content.Intent.EXTRA_TEXT, "How are you"); //set your message

        String imagePath = Environment.getExternalStorageDirectory() + File.separator + "test.jpg";

        File imageFileToShare = new File(imagePath);

        Uri uri = Uri.fromFile(imageFileToShare);

        shareIntent.putExtra(Intent.EXTRA_STREAM, uri);

        startActivity(Intent.createChooser(shareIntent, "Share Image"));
