I am using an ArrayList to loop through an application's contact list, and send SMS to these numbers for which I have the following used:

ArrayList<String> contacts = new ArrayList();
                        List<String> list = SM.getAllValue();
                            for(String string : list){
sb.append(string.toString());
                                contacts.add(string);
                                }
                            for(int i = 0; i <= contacts.size(); i++){
                                String numberToSend = contacts.get(i).toString();
                                sendSMS(numberToSend, sms);
                            }

The code SM.getAllValues()returns all the user's contact preferences in List(s). The program works- the messages are sent but the application crashes every single time, giving the following in the logcat:

Change 

for(int i = 0; i <= contacts.size(); i++){

To

for(int i = 0; i < contacts.size(); i++){
