NB:- i read all anser about problem like this but it is the same thing nothing change - the service had no relation with the activity.

It looks you are not following a standard design pattern for interacting an activity with the service. Please re-think the case of activity service interaction. If you want to reuse the method for getting the call records, put this method in an utils class and pass a context to get the call logs-

private static String getCallDetails(Context context) {
StringBuffer stringBuffer = new StringBuffer();
Cursor cursor = context.getContentResolver().query(CallLog.Calls.CONTENT_URI,
        null, null, null, CallLog.Calls.DATE + " DESC");
int number = cursor.getColumnIndex(CallLog.Calls.NUMBER);
int type = cursor.getColumnIndex(CallLog.Calls.TYPE);
int date = cursor.getColumnIndex(CallLog.Calls.DATE);
int duration = cursor.getColumnIndex(CallLog.Calls.DURATION);       
while (cursor.moveToNext()) {
    String phNumber = cursor.getString(number);
    String callType = cursor.getString(type);
    String callDate = cursor.getString(date);
    Date callDayTime = new Date(Long.valueOf(callDate));
    String callDuration = cursor.getString(duration);
    String dir = null;
    int dircode = Integer.parseInt(callType);
    switch (dircode) {
    case CallLog.Calls.OUTGOING_TYPE:
        dir = "OUTGOING";
        break;
    case CallLog.Calls.INCOMING_TYPE:
        dir = "INCOMING";
        break;

    case CallLog.Calls.MISSED_TYPE:
        dir = "MISSED";
        break;
    }
    stringBuffer.append("\nPhone Number:--- " + phNumber + " \nCall Type:--- "
            + dir + " \nCall Date:--- " + callDayTime
            + " \nCall duration in sec :--- " + callDuration);
    stringBuffer.append("\n----------------------------------");
}
cursor.close();
return stringBuffer.toString();

}

You can get context in the service by using the method calls-

          getBaseContext();
          getApplicationContext();
