Android与.Net交互模拟用户屏幕操作添加APN和网络4G/3G切换

　　前几天接到一个需求，我们的客户需要对手机网络接入点进行可用性测试，简单点说就是需要实现Android上的APN配置的添加，APN切换网络模式4G/3G/2G切换，我要调研下写个demo。

　　因为是要实现自动化测试，而且得合并到现有的拨测系统（C#项目）成为其中的一个模块，就需要用C#来驱动Android测试。交互方式上首先想到的是撸个代码放Android上，定时从服务端获取任务命令然后执行，嗯，OWIN实现个webapi进行数据交互分分钟的事情，貌似可行。不过又想到，我们测试万一网络切换坏了，就不能联网了那就完了。这样的话，就不能进行任何手机天线端的网络操作了。接着就想到USB交互然后找到了这个命令：adb forward tcp:PCPorttcp:Androidport 作用是将当前环境的某个端口与Android的某个端口绑定。这样Android 内部请求Androidport端口号就和请求PC上的PCPort端口一样，反之亦然，手机需要打开USB调试。准备写的时候我又想到，我们做的是无人值守的主动测试，Android一会儿跑过来问问有没有执行命令，一会儿跑过来问问感觉有点不大好，麻烦别人还得别人惦记着不是我的性格。。。 balabala一番思想斗争后决定用socket交互，Android端做服务端，要做啥过来说下~~

　　Android的Server端通讯简要讯码：

　　SCServer ：接收连接过来的客户端，并且保存到ClientManager中

public class SCServer implements Runnable {    static Boolean Startd = false;    static Integer Port;    static ServerSocket serverSocket = null;    ClientManager clientManager = new ClientManager();    public SCServer(int port) {        Port = port;    }    @Override    public void run() {        if (!Startd) {            try {                serverSocket = new ServerSocket(Port);                Startd = true;                System.out.println("Startd :" + Port);            } catch (IOException e) {                e.printStackTrace();            }            try {                while (Startd) {                    Socket socket = serverSocket.accept();                    clientManager.AddClient(socket);                }            } catch (IOException e) {                // TODO Auto-generated catch block                e.printStackTrace();            }        }    }    public void RegistCallBack(String comm, CallBack callBack) {        CommManager.Add(comm, callBack);    }    public void UnRegistCallBack(String comm) {        CommManager.Remove(comm);    }    public void Send(Integer clientID, String comm, Map<String, String> msgDatas) {        clientManager.SendMsg(clientID, comm, msgDatas);    }}

View Code

　　ClientManager：保存所有客户端，分配唯一编号，线程运行客户端监听消息，根据编号找到客户端Client发送消息。

public class ClientManager {    static Integer ClientID=0;    static Map<Integer, Client> Clients = new HashMap<>();    public void AddClient(Socket socket) {        Integer clientID= ClientID++;        Client clinet = new Client(socket,clientID);        new Thread(clinet).start();         Clients.put(clientID, clinet);    }    public void SendMsg(Integer clientID, String comm,            Map<String, String> msgDatas) {        if (Clients.containsKey(clientID)) {            Client client = Clients.get(clientID);            client.SendMsg(comm, msgDatas);        }    }}

View Code

　　Client：数据收发，命令解析。消息的载体是json格式FastJson处理。数据类容转换为Map<String,String>对应的为Ｃ＃的Dictionary<string, string>

public class Client implements Runnable {    private Socket socket;    private DataOutputStream dos = null;    private BufferedReader brIs = null;    private boolean bConnected = false;    public Integer ClientID = -1;    public Client(Socket socket, int id) {        this.socket = socket;        this.ClientID = id;    }    @Override    public void run() {        try {            brIs = new BufferedReader(new InputStreamReader(socket.getInputStream(), "UTF-8"));            dos = new DataOutputStream(socket.getOutputStream());            System.out.println(this.ClientID + " Start");            bConnected = true;            while (bConnected) {                String str = brIs.readLine();                if(str!=null){                System.out.println("-------->" + str);                JSONObject jb = JSON.parseObject(str);                String msgComm = jb.getString("MsgComm");                CallBack cb = CommManager.Get(msgComm);                if (cb != null) {                    String msgCBComm = jb.getString("MsgCBComm");                    Map<String, String> msgDatas = (Map<String, String>) JSON.parse(jb.getString("MsgDatas"));                    cb.execute(ClientID, msgCBComm, msgDatas);                } else {                    System.out.println("--->MsgComm:[" + msgComm+ "] Can't Find!");                }}            }        } catch (IOException e) {            e.printStackTrace();        }    }    public void SendMsg(String comm, String callBackComm,            Map<String, String> msgDatas) {        Message msg = new Message();        msg.MsgCBComm = callBackComm;        msg.MsgComm = comm;        msg.MsgDatas = msgDatas;        String StrJson = JSON.toJSONString(msg);        System.out.println("<--------"+StrJson);        try {            this.dos.writeUTF(StrJson);            this.dos.flush();        } catch (IOException e) {            e.printStackTrace();        }    }    public void SendMsg(String comm, Map<String, String> msgDatas) {        SendMsg(comm,"",msgDatas);    }}

View Code

　　CommManager：消息命令管理，保存命令关键字与回调的处理方法。

public class CommManager {    static Map<String, CallBack> Comms = new HashMap<String, CallBack>();    public static void Add(String comm, CallBack callBack) {        Comms.put(comm, callBack);    }    public static CallBack Get(String comm) {        if (Comms.containsKey(comm)) {            CallBack callBack = Comms.get(comm);            return callBack;        } else {            return null;        }    }        public static void Remove(String comm) {        Comms.remove(comm);    }}

View Code

　　CallBack:回调接口，返回客户端ID，消息返回命令，接收的消息

public interface CallBack {     public void execute(Integer clientID, String callBackComm,                Map<String, String> msgDatas);  }

View Code

　　Message：交互的消息

public class Message {    public String MsgComm;  //传过来的命令    public String MsgCBComm;//回应的命令    public Map<String,String> MsgDatas=new HashMap<String, String>();//数据}

View Code

调用方式：

以上的交互完成了，后面就是业务代码了。APN添加切换网络模式切换

网上搜了下，得到一个例子：Android开发之APN网络切换心中暗喜：有前辈给出了解决方案，还有代码实例，这实现起来还不简单么。照猫画虎。。。后发现出了个错：

 No permission to write APN settings:

查询了一翻发现android 4.0以上对这一权限进行回收了。我们的测试机为小米4，按照网上说的方法进行了重新系统签名，系统权限设置均无效，依然会有权限错误，中间为了得到android4.4.4的platform.pk8文件还下载了8G的android 4.4.4源码。可能是MIUI的与android原生的系统签名不一样总是就是要不没权限要不安装不上。网上还有一种方法是 MM编译，得在Linux环境下；Eclipse+NDK配置又是很多的配置，看着教程实在感受不到爱了。。。索性就放弃了这方案曲线救国的方式来实现需求-----模拟用户屏幕操作。 adb有个Input命令，可以模拟键盘输入，屏幕点击，屏幕滑动。

adb shell input keyevent “value”usage: input ...       input text <string>       input keyevent <key code number or name>       input tap <x> <y>       input swipe <x1> <y1> <x2> <y2>

常用键：

input keyevent 3    // Homeinput keyevent 4    // Backinput keyevent 19  //Upinput keyevent 20  //Downinput keyevent 21  //Leftinput keyevent 22  //Rightinput keyevent 23  //Select/Okinput keyevent 24  //Volume+input keyevent 25  // Volume-input keyevent 82  // Menu 菜单

抄个这段代码，Android上执行终端命令，Root权限？小米4：—_—

    public static void execShellCmd(String cmd) {        try {            // 申请获取root权限            Process process = Runtime.getRuntime().exec("su");            OutputStream outputStream = process.getOutputStream();            DataOutputStream dataOutputStream = new DataOutputStream(                    outputStream);            dataOutputStream.writeBytes(cmd);            dataOutputStream.flush();            dataOutputStream.close();            outputStream.close();        } catch (Throwable t) {            t.printStackTrace();        }    }

那么，当我需要添加一个APN的时候：

Android：

        final SCServer sc = new SCServer(57641);        sc.RegistCallBack("AddApn", new CallBack() {            @Override            public void execute(Integer clientID, String callBackComm,                    Map<String, String> msgDatas) {                Intent intent = new Intent(Settings.ACTION_APN_SETTINGS);                startActivity(intent);
　　　　　　　　　SystemClock.Sleep(1000);                for (int i = 0; i < msgDatas.values().size(); i++) {                    String strDo = msgDatas.get(i + "");                    FoolHand.execShellCmd(strDo);                    Log.d("strDo", strDo);                    SystemClock.sleep(1000);                }                msgDatas.clear();                msgDatas.put("Result", "OK");                sc.Send(clientID, callBackComm, msgDatas);            }        });

C#：

效果：

sc.RegistCallBack("SetNetMode", new CallBack() {            @Override            public void execute(Integer clientID, String callBackComm,                    Map<String, String> msgDatas) {                Intent intent = new Intent(Settings.ACTION_WIRELESS_SETTINGS);                startActivity(intent);                for (int i = 0; i < msgDatas.values().size(); i++) {                    String strDo = msgDatas.get(i + "");                    FoolHand.execShellCmd(strDo);                    Log.d("strDo", strDo);                    SystemClock.sleep(1000);                }                msgDatas.clear();                msgDatas.put("Result", "OK");                sc.Send(clientID, callBackComm, msgDatas);            }        });
