是的，AWS IoT可以连接移动设备。下面是一个示例代码，展示了如何在Android应用程序中使用AWS IoT SDK连接到AWS IoT。

首先，确保你已经在AWS控制台中创建了一个AWS IoT设备，获取了设备的证书和密钥。

1. 在build.gradle文件中添加以下依赖项：

implementation 'com.amazonaws:aws-android-sdk-iot:2.16.4'
implementation 'com.amazonaws:aws-android-sdk-core:2.16.4'

2. 在AndroidManifest.xml文件中添加以下权限：

3. 创建一个新的类，例如AWSIoTManager，并在其中添加以下代码：

import com.amazonaws.auth.CognitoCachingCredentialsProvider;
import com.amazonaws.mobileconnectors.iot.AWSIotMqttClientStatusCallback;
import com.amazonaws.mobileconnectors.iot.AWSIotMqttManager;
import com.amazonaws.regions.Regions;

public class AWSIoTManager {
    private static final String CUSTOMER_SPECIFIC_ENDPOINT = "YOUR_IOT_ENDPOINT";
    private static final String COGNITO_POOL_ID = "YOUR_COGNITO_POOL_ID";
    private static final String COGNITO_REGION = "YOUR_COGNITO_REGION";
    private static final String KEYSTORE_NAME = "YOUR_KEYSTORE_NAME";
    private static final String KEYSTORE_PASSWORD = "YOUR_KEYSTORE_PASSWORD";
    private static final String CERTIFICATE_ID = "YOUR_CERTIFICATE_ID";

    private AWSIotMqttManager mqttManager;

    public AWSIoTManager(Context context) {
        AWSMobileClient.getInstance().initialize(context).execute();
        CognitoCachingCredentialsProvider credentialsProvider = new CognitoCachingCredentialsProvider(
                context, COGNITO_POOL_ID, Regions.fromName(COGNITO_REGION));

        mqttManager = new AWSIotMqttManager(CUSTOMER_SPECIFIC_ENDPOINT, CERTIFICATE_ID, KEYSTORE_NAME, KEYSTORE_PASSWORD);
        mqttManager.setKeepAlive(10); // 设置心跳包间隔(秒)
        mqttManager.setAutoReconnect(true); // 设置自动重连
        mqttManager.setMaxAutoReconnectAttempts(10); // 设置自动重连尝试次数
        mqttManager.setReconnectRetryLimits(0, 60); // 设置重连间隔时间(秒)
        mqttManager.setClientId("YOUR_CLIENT_ID"); // 设置客户端ID
        mqttManager.setCredentialsProvider(credentialsProvider);
    }

    public void connect() {
        mqttManager.connect(credentialsProvider, new AWSIotMqttClientStatusCallback() {
            @Override
            public void onStatusChanged(final AWSIotMqttClientStatus status, final Throwable throwable) {
                if (status == AWSIotMqttClientStatus.Connecting) {
                    Log.i(TAG, "连接中...");
                } else if (status == AWSIotMqttClientStatus.Connected) {
                    Log.i(TAG, "已连接");
                } else if (status == AWSIotMqttClientStatus.Reconnecting) {
                    if (throwable != null) {
                        Log.e(TAG, "重新连接失败", throwable);
                    }
                    Log.i(TAG, "重新连接中...");
                } else if (status == AWSIotMqttClientStatus.ConnectionLost) {
                    if (throwable != null) {
                        Log.e(TAG, "连接丢失", throwable);
                    }
                    Log.i(TAG, "连接丢失");
                } else {
                    Log.i(TAG, "连接失败");
                }
            }
        });
    }

    public void publish(String topic, String message) {
        try {
            mqttManager.publishString(message, topic, AWSIotMqttQos.QOS0);
        } catch (Exception e) {
            Log.e(TAG, "发布消息失败", e);
        }
    }

    public void disconnect() {
        mqttManager.disconnect();
    }
}

请确保将YOUR_IOT_ENDPOINT、YOUR_COGNITO_POOL_ID、YOUR_COGNITO_REGION、YOUR_KEYSTORE_NAME、YOUR_KEYSTORE_PASSWORD和YOUR_CERTIFICATE_ID替换为你自己的值。

4. 在你的活动中使用AWSIoTManager类：

AWSIoTManager awsIoTManager = new AWSIoTManager(this);
awsIoTManager.connect();

// 发布消息
awsIoTManager.publish("YOUR_TOPIC", "YOUR_MESSAGE");

// 断开连接
awsIoTManager.disconnect();

将YOUR_TOPIC替换为你想
