广播接收器无法正确获取短信内容

我正在创建一个应用程序，它将获取文本消息的内容并将其显示在弹出窗口中。收到短信时，我的广播接收器无法拍摄。

广播接收器类

public class SMSReceiver extends BroadcastReceiver {

    @Override
    public void onReceive(Context context, Intent intent) {
        Bundle bundle = intent.getExtras();
        Object[] pdus = (Object[]) bundle.get("pdus");
        SmsMessage[] msgs = new SmsMessage[pdus.length];

        /** sms sender phone */
        String smsSender = "";

        /** body of received sms */
        String smsBody = "";

        /** timerstamp */
        long timestamp = 0L;

        for (int i = 0; i < msgs.length; i++) {
            msgs[i] = SmsMessage.createFromPdu((byte[]) pdus[i]);
            smsSender += msgs[i].getOriginatingAddress();
            smsBody += msgs[i].getMessageBody().toString();
            timestamp += msgs[i].getTimestampMillis();

        }
        intent.putExtra("sender", smsSender);
        intent.putExtra("body", smsBody);
        intent.putExtra("timestamp", timestamp);
    }

}

Dialog Activity公共类PopSMSActivity扩展了Activity {

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        showDialog();
    }

    private void showDialog() {
        final String sms_sender = getIntent().getStringExtra("sender");
        final String sms_body = getIntent().getStringExtra("body");
        final long timestamp = getIntent().getLongExtra("timestamp", 0L);
        final String display = sms_sender + "\n" + sms_body + "\n" + timestamp;
        AlertDialog.Builder builder = new AlertDialog.Builder(this);
        builder.setMessage(display)
                .setCancelable(false)
                .setPositiveButton("Reply",
                        new DialogInterface.OnClickListener() {
                            public void onClick(DialogInterface dialog, int id) {
                                // reply by calling SMS program
                                smsReply(sms_sender, sms_body);
                            }
                        })
                .setNegativeButton("Close",
                        new DialogInterface.OnClickListener() {
                            public void onClick(DialogInterface dialog, int id) {
                                // go back to the phone home screen
                                goHome();
                            }
                        });
        AlertDialog alert = builder.create();
        alert.show();
    }

    private void smsReply(String sender, String body) {
        Intent sendIntent = new Intent(Intent.ACTION_VIEW);
        sendIntent.putExtra("address", sender);
        sendIntent.putExtra("sms_body", body);
        sendIntent.setType("vnd.android-dir/mms-sms");
        startActivity(sendIntent);
        this.finish(); // close this Activity now
    }

    private void goHome() {
        Intent intent = new Intent(Intent.ACTION_MAIN);
        intent.addCategory(Intent.CATEGORY_HOME);
        intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
        startActivity(intent);
        this.finish();
    }
}
