Android как отправить несколько контактов в один.файл vcf и отправить на почту?
в моем приложении несколько контактов прикреплены к single .vcf файл и этот файл, отправленный на почту, попробуйте этот все контакты отображения данных в журнале cat, но не удалось отправить все данные, прикрепленные к одному .файл vcf?
у кого-нибудь есть идеи относительно этого помогите мне, пожалуйста.
вот мой код
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
* as a Global. And in Every Loop i move cursor next and print log in
* logcat.
* */
getVcardString();
}
private void getVcardString() {
cursor = getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, null, null, null);
Log.i("TAG two", "cursor" +cursor);
if (cursor != null && cursor.getCount() > 0) {
cursor.moveToFirst();
Log.i("Number of contacts", "cursorCount" +cursor.getCount());
for (int i = 0; i < cursor.getCount(); i++) {
get(cursor);
Log.i("TAG send contacts", "Contact " + (i + 1) + "VcF String is" + vCard.get(i));
cursor.moveToNext();
}
StringBuffer s = new StringBuffer();
s.append( vCard.toString());
string = s.toString();
file = new File(string);
// Log.i("s", ""+s);
// Log.i("string", ""+string);
Log.i("file", ""+file);
} else {
Log.i("TAG", "No Contacts in Your Phone");
}
}

наконец, моя проблема решена с помощью этого
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
mContext = this;
button = (Button) findViewById(R.id.send);
button.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
data();
}
});
