In my Blackberry application, I have a email address I want the user to be able to send an email to. I would like to have the built in Email Application run the compose screen with the "to" field filled in with the email address I supply, similar to how desktop mail clients respond to a "mailto" link. Does the API have a function for this?
Use the Invoke Class
With a MessageArgument
And you should be ok
If you need more customization Use the Message class with the Adress class to add to the Message en then send it to the MessageArgument then you can send it to Invoke
You can also see a more detailed explanation on RIM website
