    ArrayList<String> CphoneNo = new ArrayList<String>();
    /** Called when the activity is first created. */

            public void onClick(View v) 
            {
                readContacts();

                 adap = new LazyAdapter(getApplicationContext());
                 list.setAdapter(adap);
            }
        });

   //to add contact
         btnAdd.setOnClickListener(new OnClickListener() {

            public void onClick(View v)
            {
                Intent addcontact = new Intent(getApplicationContext(),AddingNewContactActivity.class);
                startActivity(addcontact);

            }
        });
         list.setOnItemClickListener(new OnItemClickListener() {
            public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,
                    long arg3) 
            {
                Toast.makeText(getApplicationContext(), ""+arg2, 1000).show();

                Uri uri = Uri.parse("com.android.contacts/raw_contacts/2");
                 Intent i = new Intent(Intent.ACTION_SEND); 
                 // i.setType("image/jpeg");  
                 i.setType("text/x-vcard");  
                  i.putExtra(Intent.EXTRA_STREAM, uri); 
                  startActivity(Intent.createChooser(i, "Send Contact"));

            }
        });

    }

    public void readContacts(){

                    Cnames.add(name);


                    // get the phone number
