How can I create .vcf file for a single contact?

Question

I have successfully created .vcf file for the all contacts from my android device. I have referred below link for doing so :

Export the Contacts as VCF file

and its working quite good. But, I need to convert a single contact to single .vcf file as per my requirement.

In this current code getting all the contacts using below lines :

cursor = getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, null, null, null);

and then all contacts will be covered in .vcf file.

So, What is way that I can generate .vcf file for a single contact ?

Answer 1

See the first line in the below code block. Here I am creating a new vFile everytime, this method will be called.So each contact will be saved in different files.

public void get(Cursor cursor)
    {
        vfile = "Contacts" + "_" + System.currentTimeMillis()+".vcf";


        //cursor.moveToFirst();
        String lookupKey = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts.LOOKUP_KEY));
        Uri uri = Uri.withAppendedPath(ContactsContract.Contacts.CONTENT_VCARD_URI, lookupKey);
        AssetFileDescriptor fd;
        try {
            fd = this.getContentResolver().openAssetFileDescriptor(uri, "r");

            // Your Complex Code and you used function without loop so how can you get all Contacts Vcard.??


           /* FileInputStream fis = fd.createInputStream();
            byte[] buf = new byte[(int) fd.getDeclaredLength()];
            fis.read(buf);
            String VCard = new String(buf);
            String path = Environment.getExternalStorageDirectory().toString() + File.separator + vfile;
            FileOutputStream out = new FileOutputStream(path);
            out.write(VCard.toString().getBytes());
            Log.d("Vcard",  VCard);*/

            FileInputStream fis = fd.createInputStream();
            byte[] buf = new byte[(int) fd.getDeclaredLength()];
            fis.read(buf);
            String vcardstring= new String(buf);
            vCard.add(vcardstring);

            String storage_path = Environment.getExternalStorageDirectory().toString() + File.separator + vfile;
            FileOutputStream mFileOutputStream = new FileOutputStream(storage_path, false);
            mFileOutputStream.write(vcardstring.toString().getBytes());

        } catch (Exception e1) 
        {
            // TODO Auto-generated catch block
            e1.printStackTrace();
        }
    }
