Android笔记之adb命令应用实例1(手机端与PC端socket通讯上)
由于本人学习Android也挺长时间了，一直把日记记在evernote里面，由于刚离职比较空闲就打算把evernote里的日志一遍遍整理出来发布到网上分享。
Android端的代码：
布局文件：activity_main.xml
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical" tools:context="com.example.androidusbserver.MainActivity" > <EditText android:id="@+id/etResult" android:layout_width="match_parent" android:layout_height="0dp" android:layout_weight="1" android:inputType="textMultiLine" > </EditText> <LinearLayout android:layout_width="wrap_content" android:layout_height="wrap_content" android:orientation="horizontal" > <EditText android:id="@+id/etInput" android:layout_width="200dp" android:layout_height="wrap_content"> </EditText> <Button android:id="@+id/btnSend" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Send" /> </LinearLayout> </LinearLayout>
定义广播接收者接收adb发送的命令：AdbBroadcastReceiver.java
public class AdbBroadcastReceiver extends BroadcastReceiver { private static final String TAG = "AdbBroadcastReceiver"; private static final String START_ACTION = "NotifyServiceStart"; private static final String STOP_ACTION = "NotifyServiceStop"; @Override public void onReceive(Context context, Intent intent) { String threadName = Thread.currentThread().getName(); String action = intent.getAction(); Log.d(TAG, threadName + "-->>" + "AdbBroadcastReceiver onReceive START_ACTION:" + action); if (START_ACTION.equalsIgnoreCase(action)) { context.startService(new Intent(context, NetWorkService.class)); } else if (STOP_ACTION.equalsIgnoreCase(action)) { context.stopService(new Intent(context, NetWorkService.class)); } } }
定义android socket服务端接收和发送socket：NetWorkService.java
public class NetWorkService extends Service { private static final String TAG = "NetWorkService"; private static Boolean mainThreadFlag = true; private static Boolean ioThreadFlag = true; private ServerSocket serverSocket = null; private final int SERVER_PORT = 10101;// 端口号 private List<Socket> sockets = new ArrayList<Socket>(); private Handler _hander = null; @Override public IBinder onBind(Intent intent) { return new MsgSenderBinder(); } @Override public void onCreate() { super.onCreate(); } private void doListen() { if (serverSocket != null) { try { serverSocket.close(); } catch (IOException e) { e.printStackTrace(); } serverSocket = null; } try { serverSocket = new ServerSocket(SERVER_PORT); while (mainThreadFlag) { Socket socket = serverSocket.accept(); sockets.add(socket); new Thread(new ThreadReadWriterSocket(socket)).start(); } } catch (IOException e) { e.printStackTrace(); } } @Override public int onStartCommand(Intent intent, int flags, int startId) { Log.d("tt", "ConnectService-->>onStartCommand()"); mainThreadFlag = true; if (serverSocket == null || serverSocket.isClosed()) { Thread t = new Thread() { public void run() { doListen(); }; }; t.start(); } return START_NOT_STICKY; } @Override public void onDestroy() { super.onDestroy(); mainThreadFlag = false; ioThreadFlag = false; Log.v(TAG, Thread.currentThread().getName() + "-->> onDestroy serverSocket.close()"); try { for (Socket socket : sockets) { if (socket != null && !socket.isClosed()) { socket.close(); } } sockets.clear(); if (serverSocket != null) serverSocket.close(); } catch (IOException e) { e.printStackTrace(); } } class MsgSenderBinder extends Binder implements IMessage { @Override public void sendMsg(String msg) { if (sockets.size() > 0 && !TextUtils.isEmpty(msg)) { for (Socket socket : sockets) { if (!socket.isClosed()) { try { BufferedOutputStream out = new BufferedOutputStream( socket.getOutputStream()); byte[] bytes = msg.trim().getBytes(); out.write(MyUtils.intToByte(bytes.length)); out.write(bytes); out.flush(); } catch (IOException e) { e.printStackTrace(); } } } } } @Override public void receiveMsg(Handler hander) { _hander = hander; } } class ThreadReadWriterSocket implements Runnable { private Socket client; public ThreadReadWriterSocket(Socket client) { this.client = client; } @Override public void run() { Log.d(TAG, "a client has connected to server!"); BufferedInputStream in; try { InputStream is = client.getInputStream(); in = new BufferedInputStream(is); String currCMD = ""; ioThreadFlag = true; while (ioThreadFlag) { try { if (client.isClosed()) { break; } currCMD = readDataFromSocket(in); if (_hander != null && !TextUtils.isEmpty(currCMD)) { Message msg = new Message(); msg.what = 1; msg.obj = currCMD.trim(); _hander.sendMessage(msg); } if (currCMD.trim().equalsIgnoreCase("exit")) { ioThreadFlag = false; } Thread.sleep(200); } catch (Exception e) { e.printStackTrace(); } } in.close(); } catch (Exception e) { e.printStackTrace(); } finally { try { sockets.remove(client); if (client != null) { Log.v(TAG, Thread.currentThread().getName() + "-->>" + "client.close()"); client.close(); } } catch (IOException e) { Log.e(TAG, Thread.currentThread().getName() + "-->>" + "read write error"); e.printStackTrace(); } } } public String readDataFromSocket(InputStream in) { String msg = ""; byte[] tempbuffer = new byte[4]; try { int numReadedBytes = in.read(tempbuffer, 0, tempbuffer.length); if (numReadedBytes <= 0) return msg; int size = MyUtils.bytesToInt(tempbuffer); if (size > 0 && size <= 10000) { byte[] buffer = new byte[size]; int length = in.read(buffer, 0, buffer.length); if (length > 0) { msg = new String(buffer, 0, length, "utf-8"); Log.v(TAG, Thread.currentThread().getName() + "-->>" + "received data: " + msg); buffer = null; } } } catch (Exception e) { Log.v(TAG, Thread.currentThread().getName() + "-->>" + "readFromSocket error"); e.printStackTrace(); } return msg; } } }
MainActivity.java

MyUtils.java
public class MyUtils { public static int bytesToInt(byte[] bytes) { int addr = bytes[0] & 0xFF; addr |= ((bytes[1] << 8) & 0xFF00); addr |= ((bytes[2] << 16) & 0xFF0000); addr |= ((bytes[3] << 25) & 0xFF000000); return addr; } public static byte[] intToByte(int i) { byte[] abyte0 = new byte[4]; abyte0[0] = (byte) (0xff & i); abyte0[1] = (byte) ((0xff00 & i) >> 8); abyte0[2] = (byte) ((0xff0000 & i) >> 16); abyte0[3] = (byte) ((0xff000000 & i) >> 24); return abyte0; } }
