Android contacts extraction

by 
ContentResolver cr = getContentResolver();
Cursor cur = cr.query(ContactsContract.Contacts.CONTENT_URI,null, null, null, null);
String lookupKey = cur.getString(cur.getColumnIndex(ContactsContract.Contacts.LOOKUP_KEY));
Uri uri = Uri.withAppendedPath(ContactsContract.Contacts.CONTENT_VCARD_URI, lookupKey);
AssetFileDescriptor fd = this.getContentResolver().openAssetFileDescriptor(uri, "r");
FileInputStream fis = fd.createInputStream();

Above code can be used to export the contacts in vcf format. Read all the contacts from the fileInputStream object “fis”.

Also, don’t forget to add the permissions in the manifest file – 

<uses-permission android:name="android.permission.READ_CONTACTS" />

Can anyone help with importing the same .vcf file to the Android using some API?
