Question

I am trying to create an application in Android 2.2 which sends SMS to 6 different contacts the same msg automatically in background as a Service using android.telephony.SmsManager which supports both CDMA and GSM.

I saw many threads which has a code snippet but they are using which are deprecated i.e. import android.telephony.gsm.SmsManager; so i just replaced it with import android.telephony.SmsManager and wrote the following code & it works

  SmsManager sms = SmsManager.getDefault();
  sms.sendTextMessage(phoneNumber, null, message, sentPI, deliveredPI);

now ,

1) can anyone tell me the roadmap to create a service which sends up
to 6 SMS in background ?

2) moreover is it good to create another thread inside a service to
send SMS to make it run in a separate thread for fast result ?

i am pretty much new to Android Services section so i am confused what i need to use Remote Service or Local Service , please do ask if you have any question regarding my post
