Android send SMS to multiple contacts using ArrayList

Question

Im writing an app that sends an SMS to several contacts. The contacts numbers are stored in an ArrayList (was received from another activity). I am not able to use this ArrayList to pass several contacts to the built-in SMS android app. This is the code:

ArrayList<String> numbersArrayList=getIntent().getExtras().getStringArrayList("phoneNumbers");
String message= "this is a custom message";
Intent smsIntent = new Intent(Intent.ACTION_VIEW);
smsIntent.putExtra("sms_body", message); 
smsIntent.putExtra("address", ??????????);
smsIntent.setType("vnd.android-dir/mms-sms");
startActivity(smsIntent);

I can iterate and print these contacts to the LogCat the simple "for each" loop and overriding toString method.

Use this code..

String toNumbers = "";
for ( String s : numbersArrayList)  
{  
    toNumbers = toNumbers + s + ";"
}  
toNumbers = toNumbers.subString(0, toNumbers.length - 1);
String message= "this is a custom message";

Uri sendSmsTo = Uri.parse("smsto:" + toNumbers);
                Intent intent = new Intent(
                        android.content.Intent.ACTION_SENDTO, sendSmsTo);
                intent.putExtra("sms_body", message);
                startActivity(intent);
