AndroidStudyMemo＝Opens vcf attachments in emails and let user create a contact

received a mail with a vCard attachment but can't open it, this simple application that just opens the contacts creator with the information and let the user create a new contact or add to an existing one.

 

Card-catcher is (and should be) invisible, it just waits for opening an attachment and opens the add contact thing with the info from the vCard. But after adding the contact, the back key goes back to the form of Card-catcher.
