我正在为
Android手机编写多人游戏.通过蓝牙进行通信.我已设法使用输入/输出流将字节从一个电话发送到另一个电话.因为我需要能够传输我想要的对象流的对象.但是,当我尝试使用我的流创建一个Objectstream时,我的程序挂起了指令.
public class ConnectedThread extends Thread {
private static final String TAG = "Connected Thread";
private final BluetoothSocket mmSocket;
private final InputStream mmInStream;
private final OutputStream mmOutStream;
private Handler mHandler;
private ObjectInputStream ois;
private ObjectOutputStream oos;
public ConnectedThread(BluetoothSocket socket,Handler h) {
mmSocket = socket;
mHandler = h;
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) { }
mmInStream = tmpIn;
mmOutStream = tmpOut;
Log.d(TAG,"attempting to create OIS");
try {
ois = new ObjectInputStream(mmInStream);
//指令new ObjectInputStream(mmInStream)永远不会完成执行.它似乎没有抛出错误,因为我抓住了它.它只是挂在这个指令.此行下面的代码都没有执行过.
} catch (Exception e) {
Log.e(TAG,"Error");
Log.d(TAG,e.getMessage());
e.printStackTrace();
}
Log.d(TAG,"attempting to create OOS");
try {
oos = new ObjectOutputStream(mmOutStream);
} catch (IOException e) {
Log.e(TAG,"IO exception for Output Stream,I have no idea what caused this");
Log.d(TAG,e.getMessage());
}
}
public void run() {.....}
我究竟做错了什么？
解决方法
在构造ObjectInputStream之前,只需构造ObjectOutputStream,并在两端刷新().您不必编写自己的任何数据.
