Java Android蓝牙反序列化对象NotFoundException,java,android,bluetooth,bluecove,Java,Android,Bluetooth,Bluecove,我在通过蓝牙反序列化我的类时遇到了一些麻烦。从pc到android设备im在我的pc应用程序上使用bluecove snapshot 2.1.1库android上的inputstream确实会收到字节，因为一旦我向OutStream发送一些数据，我的android应用程序就会崩溃。这是我的堆栈跟踪。此外，蓝牙插座也在工作，因为我可以在pc上将整数发送到字节 W/System.err: java.lang.ClassNotFoundException: bluetooth.LiteProject

在我的android代码中，我接收对象并对其进行反序列化

public class BluetoothDataShare extends Thread {
 private final BluetoothSocket mmSocket;
        private static InputStream mmInStream;
        private static  OutputStream mmOutStream ;
        public static LiteProject lite = null;

public BluetoothDataShare(BluetoothSocket socket) {
            mmSocket = socket;
            InputStream tmpIn = null;
            OutputStream tmpOut = null;

            // Get the input and output streams, using temp objects because
            // member streams are final
            try {
                tmpIn = socket.getInputStream();
                tmpOut = socket.getOutputStream();
            } catch (IOException e) {
                Log.e(TAG, "temp sockets not created");    
            }    
            mmInStream = tmpIn;
            mmOutStream = tmpOut;   

        }


    public static LiteProject deserialize() {

        ObjectInputStream o = null;
        LiteProject liteProject = null;
        try {
            o = new ObjectInputStream(mmInStream);
        } catch (IOException e) {
            e.printStackTrace();
        }

        try {
            liteProject = (LiteProject) o.readObject();
            o.close();
        } catch (IOException e) {
            e.printStackTrace();
        } catch (ClassNotFoundException e) {
            e.printStackTrace();
        }    
        return  liteProject;
    }    


    /* Call this from the main activity to send data to the remote device */
        public void write(byte[] bytes) {
            try {
                mmOutStream.write(bytes);
            } catch (IOException e) { }
        }

        /* Call this from the main activity to shutdown the connection */
        public void cancel() {
            try {
                mmSocket.close();
            } catch (IOException e) {
                Log.e(TAG, "close of connect socket failed");
            }
        }
}

这是我在pc上序列化的代码

public static byte[] serialize(LiteProject liteProject){
        ByteArrayOutputStream b = new ByteArrayOutputStream();
        try(ObjectOutputStream o = new ObjectOutputStream(b)){
        o.writeObject(liteProject);

        }catch(IOException ex ){}
        return b.toByteArray();            
    }

这是outputStream初始化的地方

private StreamConnection mConnection;

    // Constant that indicate command from devices
    private static final int EXIT_CMD = -1;
    private static final int SWIPE_RIGHT = 1;
    private static final int SWIPE_LEFT = 2;
    public static OutputStream outputStream;

    public ProcessConnectionThread(StreamConnection connection)
    {
        mConnection = connection;
    }

    @Override
    public void run() {
        try {

            // prepare to receive data
            InputStream inputStream = mConnection.openInputStream();
            outputStream = mConnection.openOutputStream();

            System.out.println("waiting for input");

            while (true) {

                int command = inputStream.read();

                if (command == EXIT_CMD)
                {
                    System.out.println("finish process");
                    break;
                }

                processCommand(command);
            }
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

这是outputstream将序列化对象发送到android设备的地方

    if(isSelected()){
    OutputStream outputStream = ProcessConnectionThread.outputStream;

    if(outputStream != null){
        Project project = projects.get(selectedIndex());
        LiteProject liteProject = new LiteProject(project);
        outputStream.write(ProjectMethods.serialize());

最后，这是LiteProject类，两边都是一样的（pc和android）

public class LiteProject implements Serializable {
    private static final long serialVersionUID = 2L;
    private int slideCount;
    private String[] notes;
    private int[] animationsCount;
    private String name;

    public LiteProject(Project project){
        slideCount =  project.getSlideCount();
        notes = project.notes;
        name = project.getName();       
    }
    public String getName(){return name;}
