Android - contact list, vcard export and import

There are 3 buttons on the main screen. 1) Clicking on the “Select Contact to send as business card” will open up the contact list. Selecting a contact will bring up the sms app with the selected contact attached as a Vcard file. 2) Clicking on the Select Contacts to send as email will open up contact list, allowing user to do multiple selection. Clicking an “Ok” button will open up the email app, with the selected contacts attached as Vcard file. 3) Clicking on “import contacts from a Vcard file” will allow user to search in SD card for .vcf file to import into contacts list. Do not overwrite duplicates. - You are required to submit source codes, not just apk files. We will do the signing. - This app needs to be compatible with Cupcake, Donut, Eclair and Froyo (please be careful with the Contacts list handling). PM me if you have any question. Do not bother to bid if you require more than 7 days for this entire project. - There is no need for additional graphics/ animations
