inputDispatcher 分发事件包含服务端dispatch事件

notify是745线程，dispatch是744线程。是2个独立线程。notifyMotion应该是inputReader线程

inPutReader收到事件，调用notifyMotion通知给InputDispatcher，放入Inbound队列，然后wake唤醒

void InputDispatcher::notifyMotion(const NotifyMotionArgs* args) {
#if DEBUG_INBOUND_EVENT_DETAILS
    ALOGD("notifyMotion - eventTime=%lld, deviceId=%d, source=0x%x, policyFlags=0x%x, "
...

        needWake = enqueueInboundEventLocked(newEntry);
        mLock.unlock();
    } // release lock

    if (needWake) {
        mLooper->wake();
    }
}

然后开始resetANRTimeoutsLocked ，开始分发事件dispatchMotionLocked，然后到dispatchEventLocked

void InputDispatcher::dispatchOnceInnerLocked(nsecs_t* nextWakeupTime) {
    nsecs_t currentTime = now();

   ...

        // Get ready to dispatch the event.
        resetANRTimeoutsLocked();
    }

    case EventEntry::TYPE_MOTION: {
        MotionEntry* typedEntry = static_cast<MotionEntry*>(mPendingEvent);
        if (dropReason == DROP_REASON_NOT_DROPPED && isAppSwitchDue) {
            dropReason = DROP_REASON_APP_SWITCH;
        }
        if (dropReason == DROP_REASON_NOT_DROPPED
                && isStaleEventLocked(currentTime, typedEntry)) {
            dropReason = DROP_REASON_STALE;
        }
        if (dropReason == DROP_REASON_NOT_DROPPED && mNextUnblockedEvent) {
            dropReason = DROP_REASON_BLOCKED;
        }
        done = dispatchMotionLocked(currentTime, typedEntry,
                &dropReason, nextWakeupTime);
        break;
    }
    }

logOutboundMotionDetailsLocked打印DispatchMotion LOG开始分发

bool InputDispatcher::dispatchMotionLocked(
        nsecs_t currentTime, MotionEntry* entry, DropReason* dropReason, nsecs_t* nextWakeupTime) {
    // Preprocessing.
    if (! entry->dispatchInProgress) {
        entry->dispatchInProgress = true;

        logOutboundMotionDetailsLocked("dispatchMotion - ", entry);
    }

//inputTargets这里就是需要接收的个数，是一个线程，通过for循环来一个一个分发
打印LOG dispatchEventToCurrentInputTargets，然后执行prepareDispatchCycleLocked

void InputDispatcher::dispatchEventLocked(nsecs_t currentTime,
        EventEntry* eventEntry, const Vector<InputTarget>& inputTargets) {
#if DEBUG_DISPATCH_CYCLE
    ALOGD("dispatchEventToCurrentInputTargets");
#endif
    pokeUserActivityLocked(eventEntry);

    for (size_t i = 0; i < inputTargets.size(); i++) {
        const InputTarget& inputTarget = inputTargets.itemAt(i);

        ssize_t connectionIndex = getConnectionIndexLocked(inputTarget.inputChannel);
        if (connectionIndex >= 0) {
            sp<Connection> connection = mConnectionsByFd.valueAt(connectionIndex);
            prepareDispatchCycleLocked(currentTime, connection, eventEntry, &inputTarget); //走这里
        } else {

        }
    }
}

void InputDispatcher::enqueueDispatchEntriesLocked(nsecs_t currentTime,
        const sp<Connection>& connection, EventEntry* eventEntry, const InputTarget* inputTarget) {
    bool wasEmpty = connection->outboundQueue.isEmpty();

    // Enqueue dispatch entries for the requested modes.
    enqueueDispatchEntryLocked(connection, eventEntry, inputTarget,
            InputTarget::FLAG_DISPATCH_AS_HOVER_EXIT);
    enqueueDispatchEntryLocked(connection, eventEntry, inputTarget,
            InputTarget::FLAG_DISPATCH_AS_OUTSIDE);
    enqueueDispatchEntryLocked(connection, eventEntry, inputTarget,
            InputTarget::FLAG_DISPATCH_AS_HOVER_ENTER);
    enqueueDispatchEntryLocked(connection, eventEntry, inputTarget,
            InputTarget::FLAG_DISPATCH_AS_IS);
    enqueueDispatchEntryLocked(connection, eventEntry, inputTarget,
            InputTarget::FLAG_DISPATCH_AS_SLIPPERY_EXIT);
    enqueueDispatchEntryLocked(connection, eventEntry, inputTarget,
            InputTarget::FLAG_DISPATCH_AS_SLIPPERY_ENTER);

    // If the outbound queue was previously empty, start the dispatch cycle going.
    if (wasEmpty && !connection->outboundQueue.isEmpty()) {
        startDispatchCycleLocked(currentTime, connection);
    }
}

startDispatchCycleLocke开始dispatch事件，是在一个while循环里，调用到inputPublisher.publishMotionEvent

void InputDispatcher::startDispatchCycleLocked(nsecs_t currentTime,
        const sp<Connection>& connection) {
#if DEBUG_DISPATCH_CYCLE
    ALOGD("channel '%s' ~ startDispatchCycle",
            connection->getInputChannelName());
#endif

    while (connection->status == Connection::STATUS_NORMAL
            && !connection->outboundQueue.isEmpty()) {
        DispatchEntry* dispatchEntry = connection->outboundQueue.head;
        dispatchEntry->deliveryTime = currentTime;
...
        case EventEntry::TYPE_MOTION: {
            MotionEntry* motionEntry = static_cast<MotionEntry*>(eventEntry);
...
            // Publish the motion event.
            status = connection->inputPublisher.publishMotionEvent(dispatchEntry->seq,
                    motionEntry->deviceId, motionEntry->source, motionEntry->displayId,
                    dispatchEntry->resolvedAction, motionEntry->actionButton,
                    dispatchEntry->resolvedFlags, motionEntry->edgeFlags,
                    motionEntry->metaState, motionEntry->buttonState,
                    xOffset, yOffset, motionEntry->xPrecision, motionEntry->yPrecision,
                    motionEntry->downTime, motionEntry->eventTime,
                    motionEntry->pointerCount, motionEntry->pointerProperties,
                    usingCoords);
            break;
        }
...

        // Re-enqueue the event on the wait queue.
        connection->outboundQueue.dequeue(dispatchEntry);
        traceOutboundQueueLengthLocked(connection);
        connection->waitQueue.enqueueAtTail(dispatchEntry);
        traceWaitQueueLengthLocked(connection);
    }
}

InputTransport.cpp的publishMotionEvent，打印LOG，并且sendMessage

status_t InputPublisher::publishMotionEvent(
        uint32_t seq,
 {
#if DEBUG_TRANSPORT_ACTIONS
    ALOGD("channel '%s' publisher ~ publishMotionEvent: seq=%u, deviceId=%d, source=0x%x, "
            "action=0x%x, actionButton=0x%08x, flags=0x%x, edgeFlags=0x%x, "
            "metaState=0x%x, buttonState=0x%x, xOffset=%f, yOffset=%f, "
            "xPrecision=%f, yPrecision=%f, downTime=%lld, eventTime=%lld, "
            "pointerCount=%" PRIu32,
            mChannel->getName().string(), seq,
            deviceId, source, action, actionButton, flags, edgeFlags, metaState, buttonState,
            xOffset, yOffset, xPrecision, yPrecision, downTime, eventTime, pointerCount);
#endif
...
    return mChannel->sendMessage(&msg);
}

sendMessage调用LOG sent message完成服务端dispatcher

status_t InputChannel::sendMessage(const InputMessage* msg) {
    size_t msgLength = msg->size();
    ssize_t nWrite;
    do {
        nWrite = ::send(mFd, msg, msgLength, MSG_DONTWAIT | MSG_NOSIGNAL);
    } while (nWrite == -1 && errno == EINTR);

...
#if DEBUG_CHANNEL_MESSAGES
    ALOGD("channel '%s' ~ sent message of type %d", mName.string(), msg->header.type);
#endif
    return OK;
}

但是，我们较为熟悉的事件接收方法View#onTouchEvent里并没有调进去，在onTouchEvent里添加log，在点击的时候会有输出，但是滑动时没有输出，mouse设备的滑动难道不一样？较为直观的分析方法是打开InputDispatcher里的log开关，可以看到，滑动的时候，还是会走到notifyMotion方法，我们还可以抓取systrace来查看方法调用流程。可以看出，mouse设备的事件分发流程和屏幕touch事件的流程是一样的，只是处理细节不一样。

AndroidR Input子系统（1）INotify与Epoll机制

之前写过几篇Input系统相关的分析，但是比较零散，本篇来时准备基于Android 11代码看一下Android Input子系统的大概流程，首先来学习下Linux下的INotify与Epoll机制，这两个机制主要是对Input子系统下的文件节点的增删和文件节点发生的事件进行监听。 INotify机制 INotify是Linux提供给用户态监听内核文件系统变化的机制，可以监听文件/目录的增删等。INotify的用法很简单，首先需要调用如下代码创建一个文件描述符： int inotifyfd = inoti

一、ANR说明和原因1.1 简介ANR全称：Application Not Responding，也就是应用程序无响应。1.2 原因Android系统中，ActivityManagerService(简称AMS)和WindowManagerService(简称WMS)会检测App的响应时间，如果App在特定时间无法相应屏幕触摸或键盘输入时间，或者特定事件没有处理完毕，就会出现ANR。以下四个条件都...

新入队的触摸事件的目标是另一个窗口，则将这个新事件保存到mNextUnblockEvent中，随后的dispatchOnceInnerLocked()会将此事件之。EventEntry是输入事件在InputDispatcher中的存在形式，另外，由于InputDispatcher在没有事件可以派发时，会进入休眠。为事件寻找合适的目标窗口。因此在前一个事件的派发。这个程序，然而由于派发事件的串行性，用户所按的HOME键在其之前的输入事件成功派发给无响应的窗口之前无法获得派发的机会，因此在ANR。

Android中AIDL进程间通信使用详解
fanxb的博客
03-09 923
一、概述 AIDL 是Android的进程间通信（IPC）比较常用的一种方式，AIDL 是 Android Interface Definition Language 的缩写，即Android接口定义语言。 Android中，每一个进程都有自己的Dalvik VM实例，拥有一个独立的内存空间，进程与进程之间是不共享内存的，每个进程都在自己的内存空间内进程数据存储，有时候我们需要两个进程之间进行数据交互，这就产生了进程间通信的需求。 AIDL优点： 1.进程间通信不止有AIDL，我们还有其..
