Solution 1:

It took a little until I understood your problem. I checked the full source code of the SDK, it is true there is no other constant you could use. However the string you are searching for is "text/plain". You can insert it directly.

However I would suggest to use another code:

IntentemailIntent=newIntent(Intent.ACTION_SENDTO,
                                Uri.fromParts("mailto", "you@example.com", null));
emailIntent.putExtra(Intent.EXTRA_EMAIL, /*...*/);
emailIntent.putExtra(Intent.EXTRA_SUBJECT, /*...*/);
emailIntent.putExtra(Intent.EXTRA_TEXT, /*...*/);
startActivityForResult(emailIntent, 1);

This intent will just open real mail clients.
