Android :: Method To Shift Through Contacts Contrast / Error On Intent

I figured out the method to shifting through the contacts contract but now get a weird error on the intent. I think I have the right manifest.

@Override // the class that is called every time the user clicks something
protected void onListItemClick(ListView l, View v, int position, long id) {
// TODO Auto-generated method stub
super.onListItemClick(l, v, position, id);
// the reflections of a applications intent to perform some activity
// in this case a call action to dial the phone
Intent i = new Intent(Intent.ACTION_CALL);
// cursor of the selection Cursor c = (Cursor) mAdapter.getItem(position);
// get some info from the cursor
String contactId = c.getString(c.getColumnIndex(Contacts._ID));
String IsPhone = c.getString(c.getColumnIndex(Contacts.HAS_PHONE_NUMBER));
//if the selection has phone numbers if (Integer.parseInt(IsPhone)> 0) {
Cursor phones = getContentResolver().query(Phone.CONTENT_URI, null, Phone.CONTACT_ID + "=" + contactId, null, null);
while (phones.moveToNext()) { String strPhoneNumber = phones.getString(phones.getColumnIndex(Phone.NUMBER)); System.out.println(strPhoneNumber);
i.setData(Phone.CONTENT_URI);
} } //i.setData(strPhoneNumber);
// Causes the dialer to appear on the screen and initiate the phone call //startActivity(i);
