基于回合的Android应用程序（蓝牙）

Question

我在蓝牙Android应用/游戏上工作，这包括两个通过蓝牙连接的玩家，并尝试猜测对方的号码。

这就是我所做的：

• 通过蓝牙连接两台设备。
• 选择您的电话号码。
• 尝试猜测对方的号码并获得结果。
• 显示对手的猜测。
• 赢，如果有人猜对方的号码。

这是我无法解决的问题：

• 当两者都选择数字时，随机将转弯设为1，并禁用对方的UI。
• 每回合放一个计时器。

我想我需要两个设备之间的处理程序，但我不知道如何实现它。如果你能帮我解决一些问题，我很感激。

这是应用的screenshot。

这是我的代码的一部分：

    @Override
    public boolean handleMessage(Message msg) {
        switch (msg.what) {

                switch (msg.arg1) {
                    case ServicioBluetooth.STATE_CONNECTED:
                        actionBar.setSubtitle("Conectado: " + connectingDevice.getName());
                        empezarJuego();
                        break;
