最近在对Android手机做自动化测试，需要管理手机设备，需要监听手机设备的上线与下线，谷歌ddmlib包提供了解决方案。下面直接贴出代码。

1、首先新建DeviceChangeListener，实现AndroidDebugBridge.IDeviceChangeListener接口，里面有三个方法，分别是手机连接、离线、状态改变的接口。

package com.nii.desktop.adb;
    
    import com.android.ddmlib.AndroidDebugBridge;
    import com.android.ddmlib.IDevice;
    
    /**
     * Created by wzj on 2017/8/21.
     */
    public class DeviceChangeListener implements AndroidDebugBridge.IDeviceChangeListener
    {
        /**
         * Sent when the a device is connected to the {@link AndroidDebugBridge}.
         * <p>
         * This is sent from a non UI thread.
         *
         * @param device the new device.
         */
        @Override
        public void deviceConnected(IDevice device)
        {
            System.out.println("Device connect " + device.getSerialNumber());
        }
    
        /**
         * Sent when the a device is connected to the {@link AndroidDebugBridge}.
         * <p>
         * This is sent from a non UI thread.
         *
         * @param device the new device.
         */
        @Override
        public void deviceDisconnected(IDevice device)
        {
            System.out.println("Device disconnect " + device.getSerialNumber());
        }
    
        /**
         * Sent when a device data changed, or when clients are started/terminated on the device.
         * <p>
         * This is sent from a non UI thread.
         *
         * @param device     the device that was updated.
         * @param changeMask the mask describing what changed. It can contain any of the following
         *                   values: {@link IDevice#CHANGE_BUILD_INFO}, {@link IDevice#CHANGE_STATE},
         *                   {@link IDevice#CHANGE_CLIENT_LIST}
         */
        @Override
        public void deviceChanged(IDevice device, int changeMask)
        {
            if (device.isOnline())
            {
                System.out.println("Device change online " + device.getSerialNumber());
            }
            else
            {
                System.out.println("Device change offline " + device.getSerialNumber());
            }
        }
    }

2、对AndroidDebugBridge类做一次封装，封装初始化、注册监听器、移除监听器、销毁等方法

package com.nii.desktop.adb;
    
    import com.android.ddmlib.AndroidDebugBridge;
    import com.android.ddmlib.IDevice;
    
    /**
     * Created by wzj on 2017/8/21.
     */
    public class AndroidDebugBridgeWrapper
    {
        /**
         * android bridge
         */
        private AndroidDebugBridge mAdbBridge;
    
    
        public AndroidDebugBridgeWrapper()
        {
        }
    
        public void init(boolean clientSupport)
        {
            AndroidDebugBridge.init(clientSupport);
            mAdbBridge = AndroidDebugBridge.createBridge("adb", false);
        }
        
        /**
         * 注册设备监听器
         *
         * @param listener 监听器
         */
        public void addDeviceChangeListener(AndroidDebugBridge.IDeviceChangeListener listener)
        {
            AndroidDebugBridge.addDeviceChangeListener(listener);
        }
    
        /**
         * 移除监听器
         *
         * @param listener 监听器
         */
        public void removeDeviceChangeListener(AndroidDebugBridge.IDeviceChangeListener listener)
        {
            AndroidDebugBridge.removeDeviceChangeListener(listener);
        }
    
        public void terminate()
        {
            AndroidDebugBridge.terminate();
        }
    
        public void disconnectBridge()
        {
            AndroidDebugBridge.disconnectBridge();
        }
    }

3、最后新建提供服务的DeviceManager设备管理类，该类是单例，通过该类可以获取设备列表，启动服务等操作。

package com.nii.desktop.adb;
    
    /**
     * 设备管理类
     * Created by wzj on 2017/8/21.
     */
    public class DeviceManager
    {
        /*
         * 单例
         */
        private static DeviceManager INSTANCE = null;
    
        /**
         * 包装类
         */
        private AndroidDebugBridgeWrapper androidDebugBridgeWrapper;
    
        /**
         * 设备监听器
         */
        private DeviceChangeListener deviceChangeListener;
    
        /**
         * 私有构造函数
         */
        private DeviceManager()
        {
    
        }
    
        /**
         * 获取单例类
         * @return DeviceManager
         */
        public static DeviceManager getInstance()
        {
            if (INSTANCE == null)
            {
                INSTANCE = new DeviceManager();
            }
    
            return INSTANCE;
        }
    
        /**
         * 启动方法
         */
        public void start()
        {
            androidDebugBridgeWrapper = new AndroidDebugBridgeWrapper();
            deviceChangeListener = new DeviceChangeListener();
    
            androidDebugBridgeWrapper.addDeviceChangeListener(deviceChangeListener);
            androidDebugBridgeWrapper.init(false);
    
            System.out.println("Device manager start successful.");
        }
    
        /**
         * 销毁方法
         */
        public void destory()
        {
            if (androidDebugBridgeWrapper == null)
            {
                return;
            }
    
            androidDebugBridgeWrapper.removeDeviceChangeListener(deviceChangeListener);
            androidDebugBridgeWrapper.terminate();
        }
    
    }

4、如何使用呢？调用DeviceManager的start方法就启动了设备管理，由于启动有点慢，放到线程中启动。

private void startDeviceManager()
        {
            new Thread(new Runnable()
            {
                @Override
                public void run()
                {
                    DeviceManager.getInstance().start();
                }
            }).start();
        }

可以看到，监听器已经在正常的工作了，下面是日志窗口的输出。
