Android Sending SMS in background.

Sending an SMS in background is quite simple. below is the code that will let one do that

public void sendSMS(String message,String destination)

{

    SmsManager smsManager = SmsManager.getDefault();

    if( smsManager != null )

    {

        PendingIntent sentPI = PendingIntent.getBroadcast(AppUtils.getAppContext(), 0,

                                                          new Intent(AppUtils.getAppContext(), SMSSentStatusReceiver.class), 0);

        PendingIntent deliveredPI = PendingIntent.getBroadcast(AppUtils.getAppContext(), 0,

                                                               new Intent(AppUtils.getAppContext(), SMSDeliveryStatusReceiver.class), 0);

        smsManager.sendTextMessage(destination,null,message,sentPI,deliveredPI);

    }

}

Note that there are two receivers one is SMSSentStatusReceiver and SMSDeliveryStatusReceiver which will receive the callbacks to update the status of sent and delivery respectively.
