Android : how to open a mail composer view?

I just want to know how to open Mail Composer in Android.

With iOS, I would do something like this :

MFMailComposeViewController *controller = [[MFMailComposeViewController alloc] init];
[controller setSubject:@"Mail subject"];
[controller setMessageBody:@"Mail body" isHTML:bool];
[controller setToRecipients:recipientsList];
if(controller) [self presentModalViewController:controller animated:YES];

How about Android ?

Thanks a lot.
