I try to send text by intent.
I make mail address.

String to = new String("xxxxx@gmail.com");

I make subject.

String title = new String("Hello");

I make text contents.

String text = new String("test");

I make Intent and set action.

Intent in = new Intent();
in.setAction(Intent.ACTION_SENDTO);

I set mail address.

in.setData(Uri.parse("mailto:" + to));

I set subject.

in.putExtra(Intent.EXTRA_SUBJECT, title);

I set text contents.

in.putExtra(Intent.EXTRA_TEXT, text);

I send text.

startActivity(in);
