【Android】在 activtiy中使用 BroadcastReceiver 接收簡訊(SMS)

private final static String MSG_RECEIVED = "android.provider.Telephony.SMS_RECEIVED";


  @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.xxxxxxx);

        // BroadcastReceiver
        registerReceiver(mBroadcastReceiver,new IntentFilter(MSG_RECEIVED));

    }


    private BroadcastReceiver mBroadcastReceiver = new BroadcastReceiver() {

        @Override
        public void onReceive(Context arg0, Intent intent) {
            // TODO Auto-generated method stub
            if (intent.getAction().equals(MSG_RECEIVED)) {

                Bundle bundle = intent.getExtras();

                if (null != bundle) {

                    Object[] pdus = (Object[]) bundle.get("pdus");
                    SmsMessage[] smg = new SmsMessage[pdus.length];

                    for (int i = 0; i < pdus.length; i++) {
                        smg[i] = SmsMessage.createFromPdu((byte[]) pdus[i]);
                        Log.i(TAG + "smg" + i, smg[i].toString());
                    }
                    for (SmsMessage cursmg : smg) {

                        String displayMessageBody = cursmg.getDisplayMessageBody();
                        String displayOriginatingAddress = cursmg.getDisplayOriginatingAddress();
                        String messageBody = cursmg.getMessageBody();
