1. Only email apps

   public void composeEmail(String[] addresses, String subject, Uri attachment) {
   Intent intent = new Intent(Intent.ACTION_SEND);
   intent.setType("*/*");
   intent.putExtra(Intent.EXTRA_EMAIL, addresses);
   intent.putExtra(Intent.EXTRA_SUBJECT, subject);
   intent.putExtra(Intent.EXTRA_STREAM, attachment);
   if (intent.resolveActivity(getPackageManager()) != null) {
       startActivity(intent);
   }
   

   }

2. Any messaging app:

   public void composeEmail(String[] addresses) {
   Intent intent = new Intent(Intent.ACTION_SENDTO);
   intent.setData(Uri.parse("mailto:")); // only email apps should handle this
   intent.putExtra(Intent.EXTRA_EMAIL, addresses);
   intent.putExtra(Intent.EXTRA_SUBJECT, "");
   if (intent.resolveActivity(getPackageManager()) != null) {
       startActivity(intent);
   }
   

   }
