查找了整个源代码，只有一个地方发现了「管理员请你离开」字符串，位置是 vizpower/imeeting/imeetingApp.java：
public void setKickoutInfo(int nReason) {
if (nReason == 1) {
this.m_strLastExitReason = "抱歉，管理员请你离开！";
this.m_bReturnToLoginView = true;
} else if (nReason == 2) {
this.m_strLastExitReason = "您的账号在另一处登录，当前客户端被强制下线";
this.m_bReturnToLoginView = true;
} else if (nReason == 3) {
this.m_strLastExitReason = "抱歉，服务器通信失败，客户端将退出！";
} else if (nReason == 4) {
this.m_strLastExitReason = "课堂时间到，客户端将退出！";
} else if (nReason == 5) {
this.m_strLastExitReason = "主讲已经结束了课堂，客户端将退出！";
} else if (nReason == 6) {
this.m_strLastExitReason = "新的主讲已在其他设备登录，您已被退出课堂！";
} else if (nReason == 7) {
this.m_strLastExitReason = "抱歉，您的设备时间异常，请重新登录！";
this.m_bReturnToLoginView = true;
}
}
// 使用 python 手动把 \u 转化成了中文另外，在 vizpower/imeeting/MainActivity[HD].java、vizpower/imeeting/MainActivityTeacher[HD].java 和 vizpower/imeeting/AssistantActivity.java 里面，有 setKickoutInfo(int) 的调用：
public void kickout(int nReason) {
if (!this.m_bIsKickouting) {
this.m_bIsKickouting = true;
iMeetingApp.getInstance().setKickoutInfo(nReason); // 这一行
if (VPWebLoginMgr.getInstance().m_b3rdAppCall) {
iMeetingApp.getInstance().alertWithExit(iMeetingApp.getInstance().m_strLastExitReason, this);
return;
}
onExit();
}
}关于 kickout(1) 的调用，仅在 vizpower/imeeting/MeetingMgr.java 中找到一处：
public void onSendUserMessage(ByteBuffer Received) {
SendUserMessagePDU PDU = new SendUserMessagePDU();
PDU.decode(Received);
for (Map.Entry<String, String> entry : PDU.PropMap.entrySet()) {
String strKey = entry.getKey();
if (strKey.compareToIgnoreCase(SendUserMessagePDU.CMDKICKOUT) == 0) {
iMeetingApp.getInstance().kickout(1); // 这一行
return;
} else if (strKey.compareToIgnoreCase(SendUserMessagePDU.CMDASSIST_RESPONSE) == 0) {
RemoteControlPadMgr.getInstance().onHostNotify(entry.getValue());
return;
}
}
}在 vizpower.imeeting.viewcontroller.RollcallConfirmViewController 中，有一个 onBtnClickRollcallConfirm()，看起来非常像实现签到的代码：
/* access modifiers changed from: private */
public void onBtnClickRollcallConfirm() {
if (this.m_pRollcallTimeoutHandler != null) {
this.m_pRollcallTimeoutHandler.removeCallbacks(this.m_pRollcallTimeoutRunnable);
}
long nowTime = (long) VPUtils.getTickCount();
if (nowTime - this.m_nLastRollCallAnswerTime > 5000) {
this.m_nLastRollCallAnswerTime = nowTime;
ReplyNamingPDU pdu = new ReplyNamingPDU();
pdu.dwUserID = MeetingMgr.myUserID();
pdu.bTime = (byte) ((int) ((nowTime - this.m_nLastRollcallStartTime) / 1000));
MeetingMgr.getInstance().m_Room.sendPDU2(pdu);
VPLog.logI("");
adjustUI(STATE_ROLLCALL_SUCCESS);
if (this.m_pRollcallTimeoutHandler != null) {
this.m_pRollcallTimeoutHandler.removeCallbacks(this.m_pRollcallTimeoutRunnable);
this.m_pRollcallTimeoutHandler.postDelayed(this.m_pRollcallCloseRunnable, 1500);
}
MeetingMgr.getInstance().addVPActionData(VPActionDef.VP_ACTION_ROLLCALL_RES, 0);
return;
}
VPLog.logW("rollcall(timeout) send too fast ignored.");
}如果能 hook 掉 vizpower.imeeting.RollCallMgr 的 startRollCall()，在末尾添加调用 onBtnClickRollcallConfirm() 或许就可以实现自动签到了：
public void startRollCall() {
if (!this.m_bCanCall) {
VPLog.logI("!m_bCanCall");
return;
}
RequestNamingPDU pdu = new RequestNamingPDU();
pdu.dwUserID = MeetingMgr.myUserID();
pdu.bTime = 20;
MeetingMgr.getInstance().m_Room.sendPDU2(pdu);
MeetingMgr.getInstance().addVPActionData(VPActionDef.VP_ACTION_ROLLCALL, 0);
