蓝牙RFComm读取崩溃的应用程序

Question

我在笔记本电脑上运行蓝牙服务器，在我的应用程序中运行蓝牙客户端。该应用程序愉快地连接到服务器，可以完美地写入数据。但是，当我添加read（）功能时，应用程序崩溃了。看起来这个命令阻止了UI线程，但我无法弄清楚为什么，因为我以为我是在一个单独的线程中运行它。我没有很多线程经验，所以我假设我错过了一些重要的东西。有人有任何线索吗？

主要活动：

public void startBluetoothConnection(BluetoothDevice device){
    alreadyConnecting = true;
    btConnection = new ConnectionService(this, device);
    manageConnectionService = btConnection.startConnection();
    //This line causes the problem...
    manageConnectionService.read();
}

ManageConnectionService：

public class ManageConnectionService extends Thread {
private final BluetoothSocket mSocket;
private final InputStream mInStream;
private final OutputStream mOutStream;
private Context mContext;

public static final String tag = "MANAGECONNECTIONSERVICE";

public ManageConnectionService(Context context, BluetoothSocket socket){
    mContext = context;
    mSocket = socket;
    InputStream tmpIn = null;
    OutputStream tmpOut = null;

    try{
        tmpIn = socket.getInputStream();
        tmpOut = socket.getOutputStream();
    }catch(IOException e){
        Log.e(tag, e.toString());
    }

    mInStream = tmpIn;
    mOutStream = tmpOut;
}

public void read() {
    byte[] buffer = new byte[1024];
    int bytes;
    int m;
    StringBuilder message = new StringBuilder(100);

    while (true) {
        try {
                    m = mInStream.read();
                    Log.i("MESSAGE RECEIVED", buffer.toString() + " length = " + m);

                    // if it's the end of the message...
                    if (m == 37) {
                        Log.i(tag, "End of message " + message.toString());
                        //Do stuff here

                        message = new StringBuilder(100);
                    } else {
                        message.append(Character.toString((char) m));
                    }


                } catch (IOException e) {
                    Log.e(tag, e.toString());
                    break;
                }
    }
}

public void write(byte[] bytes){
    try{
        mOutStream.write(bytes);
        Log.i(tag, "Sent message!");
    }catch (IOException e){
        Log.e(tag, e.toString());
    }
}

public void cancel(){
    try{
        mSocket.close();
    }catch (IOException e){
        Log.e(tag, e.toString());
    }
}

}
