Hi,王营：
请帮忙分析一下为什么屏保卡住了

#6 Updated by CD FW-程天颖 about 2 years ago

初步分析由于多线程操作导致记录屏保状态的数据，由于缺乏适当的同步机制或互斥锁，导致数据的一致性产生错误，使得屏保无法打开

【当前状态】
复现问题，怀疑DreamService中mInteractive变量异常

public boolean dispatchTouchEvent(MotionEvent event) {
// TODO: create more flexible version of mInteractive that allows clicks
// but finish()es on any other kind of activity
switch (event.getAction()){
case MotionEvent.ACTION_DOWN:
mActionDownY = event.getY();
break;
case MotionEvent.ACTION_UP:
mActionUpY = event.getY();
Slog.v(TAG, "mActionDownY = "+mActionDownY);
Slog.v(TAG, "mActionUpY = "+mActionUpY);
if (!mInteractive) {
if (mDebug) Slog.v(TAG, "Waking up on touchEvent");
if (mActionUpY < mActionDownY){
wakeUp();
return true;
}
}
break;
}
return mWindow.superDispatchTouchEvent(event);
}

【下一步】
1、确认mInteractive是否在频繁操作过程中出现异常。
2、中控遥控器向副屏发送事件频率需要添加控制，确定一个时间间隔，过于频繁的事件是不合理的，需要drop掉。

【状态】
问题原因是启动和退出屏保的动作太频繁，在屏保还没有启动完成就下发了唤醒屏保的指令，调用及变量赋值出现异常，当前有两个方案
1、对于这种不正常的操作进行规避，控制点击事件的点击频率，对framework层屏保的启动流程不做修改。
2、点击频率同样需要控制。对framework层进行控制，屏保启动流程没有结束之前不允许唤醒。

【分析】
1、正常启动屏保的log：
05-24 01:29:42.060 9655 9655 V DreamService[SystemDream]: onCreate()
05-24 01:29:42.060 9655 9655 V DreamService[SystemDream]: onBind() intent = Intent { act=android.service.dreams.DreamService flg=0x800000 cmp=com.thundercomm.screensaver/.service.SystemDream }
05-24 01:29:42.127 9655 9655 V DreamService[SystemDream]: onDreamingStarted()

2、正常退出的log：
05-24 01:29:42.182 9655 9655 V DreamService[SystemDream]: wakeUp(): fromSystem=true, mWaking=false, mFinished=false
05-24 01:29:42.182 9655 9655 V DreamService[SystemDream]: finish(): mFinished=false
05-24 01:29:42.322 9655 9655 V DreamService[SystemDream]: detach(): Calling onDreamingStopped()
05-24 01:29:42.322 9655 9655 V DreamService[SystemDream]: onDreamingStopped()
05-24 01:29:42.322 9655 9655 V DreamService[SystemDream]: finish(): mFinished=false
05-24 01:29:42.324 9655 9655 V DreamService[SystemDream]: onDestroy()
05-24 01:29:42.324 9655 9655 V DreamService[SystemDream]: finish(): mFinished=false

3、异常启动和退出屏保的log，onDreamingStarted没有执行完毕就进行了wakeup：
05-24 01:29:42.355 9655 9655 V DreamService[SystemDream]: onCreate()
05-24 01:29:42.355 9655 9655 V DreamService[SystemDream]: onBind() intent = Intent { act=android.service.dreams.DreamService flg=0x800000 cmp=com.thundercomm.screensaver/.service.SystemDream }
05-24 01:29:42.420 9655 9655 V DreamService[SystemDream]: wakeUp(): fromSystem=true, mWaking=false, mFinished=false
05-24 01:29:42.420 9655 9655 V DreamService[SystemDream]: finish(): mFinished=false
05-24 01:29:42.423 9655 9655 V DreamService[SystemDream]: finish(): mFinished=true
05-24 01:29:42.425 9655 9655 V DreamService[SystemDream]: onDestroy()
05-24 01:29:42.425 9655 9655 V DreamService[SystemDream]: finish(): mFinished=true
05-24 01:29:42.489 9655 9655 V DreamService[SystemDream]: onDreamingStarted()

【下一步】
