Question

我正在尝试通过android模拟器中的套接字发送对象。每个仿真器都将对象发送给自身和另外两个仿真器。侦听和发送对象位于两个不同的端口和线程中。它在发送第一个数据包后得到了java.io.StreamCorruptedException。在某些情况下，发送到其他仿真器的对象会到达，但发送给自身的对象在发送第一个对象后永远不会到达自身。我检查了我的对象发送和接收代码与他人，他们告诉他们没有看到任何问题，但我确实得到了一致的异常。这篇文章是最后的手段。请帮忙！

这是我的服务器主题，它一直在监听 -

public void StartListening() {
    new Thread(){
        public void run(){
            //packet p = null;
            try {
                ListenSocket =  new ServerSocket(L_PORT_NUM);
                packet p= null;
                Log.i("init","entering the listen while loop");
                while(true){
                    Socket TempSocket1 = ListenSocket.accept();
                    ois = new ObjectInputStream(TempSocket1.getInputStream());
                    p = (packet) ois.readObject();
                    decide(p);
                    ois.close();
                    TempSocket1.close();
                }
            } catch (IOException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            } catch (ClassNotFoundException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }

        }
    }.start();
}

decision（）方法产生一个新线程。因此，调用上述方法时不会产生延迟。

这是在同一个程序中，但完全不同的线程

    public void myWriteObject(packet m) throws IOException{
    final packet temp = m;
    //Create a new thread,Since network operations is not advised in main thread.
    new Thread(){
        public void run() {
            Log.i("myWriteObject","--------- ");

            int i=NUM_SYS;
            int temp_portNum=11108;

            while(i!=0){
                try {
                    Socket SendSocket1= new Socket("10.0.2.2",temp_portNum);
                    oos = new ObjectOutputStream(SendSocket1.getOutputStream());
                    oos.writeObject(temp);
                    oos.flush();
                    oos.close();
                    SendSocket1.close();

                    Log.i("myWriteObject","OBJECT SENT TO -"+temp_portNum);
                    i--;
                    temp_portNum=temp_portNum+4;
                    Thread.sleep(1000);

                } catch (UnknownHostException e) {
                    // TODO Auto-generated catch block
                    e.printStackTrace();
                } catch (IOException e) {
                    // TODO Auto-generated catch block
                    e.printStackTrace();
                } catch (InterruptedException e) {
                    // TODO Auto-generated catch block
                    e.printStackTrace();
                }
            }
        }
    }.start();

}

我不断收到java.io.StreamCorruptedException。我已经尝试过，关闭，刷新以及gogle建议的内容。但我仍然得到这个错误。以下是错误日志的摘录 - 03-17 19:18:23.361: I/CLock(int n)(1638): clock initialized0 0 0 03-17 19:18:23.370: I/init(1638): entered oncreate 03-17 19:18:23.620: I/init(1638): entering the listen while loop 03-17 19:18:24.001: D/gralloc_goldfish(1638): Emulator without GPU emulation detected. 03-17 19:18:24.420: I/ActivityManager(100): Displayed project1.DistSys.App/.Project1Activity: +2s526ms 03-17 19:18:24.981: W/NetworkManagementSocketTagger(100): setKernelCountSet(10009, 0) failed with errno -2 03-17 19:18:33.961: I/TEST1(1638): sending to EVERYONE from TEST 1-1 0 0 5554:1 03-17 19:18:33.991: I/myWriteObject(1638): --------- 03-17 19:18:34.102: I/TEST1(1638): sending to EVERYONE from TEST 1-2 0 0 5554:2 03-17 19:18:34.120: I/myWriteObject(1638): --------- 03-17 19:18:34.500: I/myWriteObject(1638): OBJECT SENT TO -11108 03-17 19:18:34.500: I/INCOMING(1638): msg value 5554:0SEQUENCER MSG value 0seq_no value 0get key stamp 5554:0clock 1 0 0 03-17 19:18:34.520: W/System.err(1638): java.io.StreamCorruptedException 03-17 19:18:34.530: I/DECIDE(1638): packets seq_no value is-0 5554:0 5554:0 03-17 19:18:34.550: W/System.err(1638): at java.io.ObjectOutputStream.writeObject(ObjectOutputStream.java:1528) 03-17 19:18:34.580: W/System.err(1638): at java.io.ObjectOutputStream.writeObject(ObjectOutputStream.java:1481) 03-17 19:18:34.580: W/System.err(1638): at project1.DistSys.App.Project1Activity$9.run(Project1Activity.java:285) 03-17 19:18:34.600: I/DECIDE-CLKSTATUS(1638): INSERT TO DB port-clock-5554 2 0 0 03-17 19:18:34.820: W/System.err(1638): java.io.EOFException 03-17 19:18:34.840: W/System.err(1638): at java.io.DataInputStream.readByte(DataInputStream.java:98) 03-17 19:18:34.850: W/System.err(1638): at java.io.ObjectInputStream.nextTC(ObjectInputStream.java:506) 03-17 19:18:34.850: W/System.err(1638): at java.io.ObjectInputStream.readNonPrimitiveContent(ObjectInputStream.java:778) 03-17 19:18:34.850: W/System.err(1638): at java.io.ObjectInputStream.readObject(ObjectInputStream.java:1999) 03-17 19:18:34.861: W/System.err(1638): at java.io.ObjectInputStream.readObject(ObjectInputStream.java:1956) 03-17 19:18:34.861: W/System.err(1638): at java.io.ObjectInputStream.readFieldValues(ObjectInputStream.java:1137) 03-17 19:18:34.880: W/System.err(1638): at java.io.ObjectInputStream.defaultReadObject(ObjectInputStream.java:455) 03-17 19:18:34.890: W/System.err(1638): at java.io.ObjectInputStream.readObjectForClass(ObjectInputStream.java:1369) 03-17 19:18:34.977: W/System.err(1638): at java.io.ObjectInputStream.readHierarchy(ObjectInputStream.java:1266) 03-17 19:18:34.977: W/System.err(1638): at java.io.ObjectInputStream.readNewObject(ObjectInputStream.java:1851) 03-17 19:18:34.977: W/System.err(1638): at java.io.ObjectInputStream.readNonPrimitiveContent(ObjectInputStream.java:787) 03-17 19:18:34.991: W/System.err(1638): at java.io.ObjectInputStream.readObject(ObjectInputStream.java:1999) 03-17 19:18:34.991: W/System.err(1638): at java.io.ObjectInputStream.readObject(ObjectInputStream.java:1956) 03-17 19:18:35.011: W/System.err(1638): at

解决问题 - 我已经将objectinputstream和objectoutputstream声明为私有，并使其成为全局的。这以某种方式破坏了流。通过使它们都是本地的，错误被消除了。
