私のアプリケーションでは、多数の連絡先が 1 つの.vcfファイルに添付され、そのファイルがメールに送信されます。これを試してみると、すべての連絡先データがログ キャットに表示されますが、1 つの .vcf ファイルに添付されたすべてのデータを送信できませんか?

誰でも私を助けてください。

ここに私のコードがあります

 public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);  

    vCard = new ArrayList<String>();                 

    Log.i("TAG one", "vfile" +vfile);
    vfile = "Contacts" + "_" + System.currentTimeMillis() + ".vcf";  

    /**
     * This Function For Vcard And here i take one Array List in Which i
     * store every Vcard String of Every Contact Here i take one Cursor and
     * this cursor is not null and its count>0 than i repeat one loop up to
     * cursor.getcount() means Up to number of phone contacts. And in Every
     * Loop i can make vcard string and store in Array list which i declared
