You can ask the email service to open a new card and have some fields filled in (to, subject, body, etc.)
this.controller.serviceRequest( 'palm://com.palm.applicationManager',
{
method: 'open',
parameters: {
id: 'com.palm.app.email',
params: {
summary: 'test subject', // subject line
recipients: [ // list of recipients
{
role:1, //1 == To, 2 == CC, 3 == BCC
value:'email@example.com',
}
],
text: "My message to you" // the email body
}
}
});
