嗨朋友，我正在尝试玩游戏服务示例，即“buttonclicker”，我想做的是，通过邀请 buttonclick 将当前时间发送给其他参与者，在这个例子中 startActivityForResult(intent,requestcode) 和另一个带有 3 个参数 startActivityForResult(intent ,requestcode,bundle)，在这里我遇到了问题；

case1：我已经尝试了带有 3 个参数的第二种方法，其中包含我当前的时间，但是当我运行该示例时，它通过错误

它的代码：

@Override
    public void onClick(View v)
    {
        Intent intent;


        Bundle BundleTimer = new Bundle();
        BundleTimer.putString("StartTime",millisecond);

        switch (v.getId()) {
            case R.id.button_single_player:
            case R.id.button_single_player_2:
                resetGameVars();
                startGame(false);
                break;
            case R.id.button_sign_in:
                // user wants to sign in
                if (!verifyPlaceholderIdsReplaced())
                {
                    showAlert("Error", "Sample not set up correctly. Please see README.");
                    return;
                }
                beginUserInitiatedSignIn();
                break;
            case R.id.button_sign_out:
                signOut();
                switchToScreen(R.id.screen_sign_in);
                break;
            case R.id.button_invite_players:
                // show list of invitable players
                intent = getGamesClient().getSelectPlayersIntent(1, 3);

                switchToScreen(R.id.screen_wait);
                startActivityForResult(intent, RC_SELECT_PLAYERS, BundleTimer);
                break;
            case R.id.button_see_invitations:
                // show list of pending invitations
                intent = getGamesClient().getInvitationInboxIntent();

                switchToScreen(R.id.screen_wait);
                startActivityForResult(intent, RC_INVITATION_INBOX, BundleTimer);
                break;
            case R.id.button_accept_popup_invitation:
                // user wants to accept the invitation shown on the invitation
                // popup
                // (the one we got through the OnInvitationReceivedListener).
                acceptInviteToRoom(mIncomingInvitationId);
                mIncomingInvitationId = null;
                break;
        }
    }

case2：在这里我尝试使用 intent.putextra("statrtime",millisecond) 发送有意图的数据，但是当我尝试在运行相同示例代码的其他应用程序中检索此额外值时，它通过来自意图的 getextra 上的 nullpointer；

它的代码

 @Override
    public void onClick(View v)
    {
        Intent intent;


        switch (v.getId()) {
            case R.id.button_single_player:
            case R.id.button_single_player_2:
                resetGameVars();
                startGame(false);
                break;
            case R.id.button_sign_in:
                // user wants to sign in
                if (!verifyPlaceholderIdsReplaced())
                {
                    showAlert("Error", "Sample not set up correctly. Please see README.");
                    return;
                }
                beginUserInitiatedSignIn();
                break;
            case R.id.button_sign_out:
                signOut();
                switchToScreen(R.id.screen_sign_in);
                break;
            case R.id.button_invite_players:
                // show list of invitable players
                intent = getGamesClient().getSelectPlayersIntent(1, 3);
                intent.putExtra("StartTime", millisecond);
                switchToScreen(R.id.screen_wait);
                startActivityForResult(intent, RC_SELECT_PLAYERS);
                break;
            case R.id.button_see_invitations:
                // show list of pending invitations
                intent = getGamesClient().getInvitationInboxIntent();
                intent.putExtra("StartTime", millisecond);
                switchToScreen(R.id.screen_wait);
                startActivityForResult(intent, RC_INVITATION_INBOX);
                break;
            case R.id.button_accept_popup_invitation:
                // user wants to accept the invitation shown on the invitation
                // popup
                // (the one we got through the OnInvitationReceivedListener).
                acceptInviteToRoom(mIncomingInvitationId);
                mIncomingInvitationId = null;
                break;
        }
    }

在此示例中，我想将持续时间发送给选定的玩家，以便如果他们在该时间之后没有响应，则他们不会为该请求而玩，如果他们在该时间段内响应，则允许他们玩游戏，

朋友我被困在这个问题上，请建议如何完成这个，抱歉英语不好，谢谢

你不能用意图来做到这一点。要在不同手机之间进行通信，您需要使用可以将设备连接在一起的东西。这可以是网络服务器、蓝牙、本地 wifi 网络，但在您执行此操作之前，必须在不同手机之间建立连接。
