Answer 1

Register a receiver in your manifest with highest priority:

Create BroadcastReceiver class:

public class SmsReceiver extends BroadcastReceiver {
    @Override
    public void onReceive(Context context, Intent intent) {
    }
}

Implement onReceive method:

Bundle bundle = intent.getExtras();
if (bundle != null && bundle.containsKey("pdus")) {
    Object[] pdus = (Object[]) bundle.get("pdus");
    SmsMessage sms = SmsMessage.createFromPdu((byte[]) pdus[0]);
    String senderNumber = sms.getOriginatingAddress();
    if( senderIsInBlackList(senderNumber)) {
        abortBroadcast();
    }
}
