I have an application that export the phone contacts to the sdcard in a vcf format.

I am able to fetch the contacts using the Uri ContactsContract.Data.CONTENT_URI, but I cannot retrieve Facebook contacts(images, email, facebookID....) I've surfed the web and didn't find any useful solution.

So any idea how to get Facebook contact ? Some people are talking about sql injection without any useful code/solution.

I am using the below code:

try {
    Uri uri = ContactsContract.Data.CONTENT_URI; // all contacts (without fb)
    Cursor c = mcontext.getContentResolver().query(uri, null,null, null, null);
    while (c.moveToNext()) {
        ..............
    }
} catch (Exception e) {
    e.printStackTrace();
}
