短信不发送

Question

我一直在关注一个视频，一切都在编译，但是当我点击发送时，toast 永远不会出现，消息也永远不会出现在我的手机上。我还在 Android Manifest 中添加了 SEND_SMS 权限。有什么建议吗？

SendSmsActivity.java

public class SendSmsActivity extends Activity {

    Button sendSMSBtn;
    EditText toPhoneNumberET;
    EditText smsMessageET;

        super.onCreate(savedInstanceState);
        setContentView(R.layout.sms_activity);
        sendSMSBtn = (Button) findViewById(R.id.sendSMSBtn);
        toPhoneNumberET = (EditText) findViewById(R.id.toPhoneNumberET);
