Android provides Cursor interface to get all calls logs. A cursor interface provides read-write to get the result set by database query.

Here stringOrder query will access phone calls date wise in desc order. Cursor loader basically perform queries the ContentResolver and returns a Cursor.

 private void getCallsHistory() {

  StringBuffer stringBuffer = new StringBuffer();
  String stringOrder = android.provider.CallLog.Calls.DATE + " DESC";

  Cursor cursor = cursorLoader(CallLog.Calls.CONTENT_URI, null,
    null, null, strOrder);

  int num = cursor.getColumnIndex(CallLog.Calls.NUMBER);
  int type = cursor.getColumnIndex(CallLog.Calls.TYPE);
  int date = cursor.getColumnIndex(CallLog.Calls.DATE);
  int dur = cursor.getColumnIndex(CallLog.Calls.DURATION);

  stringBuffer.append("All call logs :");

  while (cursor.moveToNext()) {
   String callNumber = managedCursor.getString(number);
   String callType = managedCursor.getString(type);
   String callDate = managedCursor.getString(date);
   Date callDate = new Date(Long.valueOf(strcallDate));
   String callDuration = managedCursor.getString(duration);
   String callType = null;
   int code = Integer.parseInt(callTypeCode);
   switch (code) {
   case CallLog.Calls.OUTGOING_TYPE:
    callType = "Outgoing";
    break;
   case CallLog.Calls.INCOMING_TYPE:
    callType = "Incoming";
    break;
   case CallLog.Calls.MISSED_TYPE:
    callType = "Missed";
    break;
   }
   sb.append("\ncalling Number:--- " + num + " \nCall Type:--- "
     + callType + " \nCall Date:--- " + callDate
     + " \nCall duration in sec :--- " + callDuration);
   sb.append("\n----------------------------------");
  }
  cursor.close();
 }
