It's actually quite easy to generate a .vcf file. Have a look at VCF format - it's a simple text file. All you need to do is create text file and write info into it using the VCF fields. You'll end up with something like this:

Person p = getPerson();

File vcfFile = new File(this.getExternalFilesDir(null), "generated.vcf");
FileWriter fw = new FileWriter(vcfFile);
fw.write("BEGIN:VCARD\r\n");
fw.write("VERSION:3.0\r\n");
fw.write("N:" + p.getSurname() + ";" + p.getFirstName() + "\r\n");
fw.write("FN:" + p.getFirstName() + " " + p.getSurname() + "\r\n");
fw.write("ORG:" + p.getCompanyName() + "\r\n");
fw.write("TITLE:" + p.getTitle() + "\r\n");
fw.write("TEL;TYPE=WORK,VOICE:" + p.getWorkPhone() + "\r\n");
fw.write("TEL;TYPE=HOME,VOICE:" + p.getHomePhone() + "\r\n");
fw.write("ADR;TYPE=WORK:;;" + p.getStreet() + ";" + p.getCity() + ";" + p.getState() + ";" + p.getPostcode() + ";" + p.getCountry() + "\r\n");
fw.write("EMAIL;TYPE=PREF,INTERNET:" + p.getEmailAddress() + "\r\n");
fw.write("END:VCARD\r\n");
fw.close();

Intent i = new Intent();
i.setAction(android.content.Intent.ACTION_VIEW);
i.setDataAndType(Uri.fromFile(vcfFile), "text/x-vcard");
startActivity(i);

(Note that this code is to be placed inside an activity. If it's not in an activity, then replace this in front of getExternalFilesDir with an instance of Context.)

You can have more of fewer fields, as needed. If you have ,, ; or \ characters in field values, they need to be escaped with \; to put a newline character into a value, write \\n into the file (i.e. the file itself must contain \n, the second slash is for escaping the slash in the newline).

This code is quite crude, but it should get you started. Again, have a look at the format of VCF and go from there.
