Questions:

In my application, a number of contacts are attached to single .vcf file and that file sent to mail, try to this one all contacts data display in log cat, but unable to send all data attached to single .vcf file?

Anyone have an idea regarding this help me, please.

here is my code

 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();

How to&Answers:

finally my issue is solved using like this

     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();
        }
    });                      

    /**

I successfully tested the following. Changes to your code are indicated with comments beginning with “CHANGE:”. Don’t forget to have android.permission.WRITE_EXTERNAL_STORAGE in your manifest.

public class MainActivity extends Activity {
    private String vfile;
    private Cursor cursor;
    private ArrayList<String> vCard;
    private String string;

        setContentView(R.layout.activity_main);
        vCard = new ArrayList<String>();                 

        Log.i("TAG one", "vfile" + vfile);
