title: Attach multiple files in Gmail fails to send - ACTION_SEND_MULTIPLE
body: <p>I need to attach multiple files in mail. The count increases as per user entry. The minimum attachment count is 2. When I try attaching 2 files and send using <code>new Intent(Intent.ACTION_SEND_MULTIPLE)</code>, it sends and receives perfectly without any issues. If I attach more or equal 4 files, it shows in attachment before sending. But fails to receive. Also if I look into the sent items, attachment was missing.</p>
  
  <pre><code>final Intent ei = new Intent(Intent.ACTION_SEND_MULTIPLE);
  ei.setType("plain/text");
  ei.putExtra(Intent.EXTRA_EMAIL, new String[] {"xyz@gmail.com"});
  ei.putExtra(Intent.EXTRA_SUBJECT, " Data Export");
  
  ei.putParcelableArrayListExtra(Intent.EXTRA_STREAM, uris);
  context.startActivity(Intent.createChooser(ei, " Data Export"));  
  </code></pre>
  
  <p>The attachment size is minimal. Generally it will be .csv files.</p>
