[DESCRIPTION]

进入camera长按拍照进行连拍，概率性出现松开拍照键连拍不停止的问题，可以按以下方法修改。

此问题属于performance问题，eng版本比user版本会多做一些mtklog等其他的操作，本身loading就比较重，所以performance相对来讲会差一些，建议修改后在user版本上进行测试。

[SOLUTION]

1、在InputDispatcher.cpp中做如下修改：

void InputDispatcher::notifyMotion(const NotifyMotionArgs* args) {

    #if DEBUG_INBOUND_EVENT_DETAILS

    ALOGD("notifyMotion - eventTime=%lld, deviceId=%d, source=0x%x, policyFlags=0x%x, "

            "action=0x%x, flags=0x%x, metaState=0x%x, buttonState=0x%x, edgeFlags=0x%x, "

            "xPrecision=%f, yPrecision=%f, downTime=%lld",

            args->eventTime, args->deviceId, args->source, args->policyFlags,

            args->action, args->flags, args->metaState, args->buttonState,

            args->edgeFlags, args->xPrecision, args->yPrecision, args->downTime);

    for (uint32_t i = 0; i < args->pointerCount; i++) {

        ALOGD("  Pointer %d: id=%d, toolType=%d, "

                "x=%f, y=%f, pressure=%f, size=%f, "

                "touchMajor=%f, touchMinor=%f, toolMajor=%f, toolMinor=%f, "

                "orientation=%f",

                i, args->pointerProperties[i].id,

                args->pointerProperties[i].toolType,

                args->pointerCoords[i].getAxisValue(AMOTION_EVENT_AXIS_X),

                args->pointerCoords[i].getAxisValue(AMOTION_EVENT_AXIS_Y),

                args->pointerCoords[i].getAxisValue(AMOTION_EVENT_AXIS_PRESSURE),

                args->pointerCoords[i].getAxisValue(AMOTION_EVENT_AXIS_SIZE),

                args->pointerCoords[i].getAxisValue(AMOTION_EVENT_AXIS_TOUCH_MAJOR),

                args->pointerCoords[i].getAxisValue(AMOTION_EVENT_AXIS_TOUCH_MINOR),

                args->pointerCoords[i].getAxisValue(AMOTION_EVENT_AXIS_TOOL_MAJOR),

                args->pointerCoords[i].getAxisValue(AMOTION_EVENT_AXIS_TOOL_MINOR),

                args->pointerCoords[i].getAxisValue(AMOTION_EVENT_AXIS_ORIENTATION));

    }

    #endif

    //add start

       bool isEmpty = mInboundQueue.isEmpty();

     if (!isEmpty)

     {

           EventEntry *tail = static_cast<MotionEntry*>(mInboundQueue.tail);

           if (tail != NULL && tail->type == EventEntry::TYPE_MOTION )

           {

                 MotionEntry* tailEntry = static_cast<MotionEntry*>(tail);

                 if (tailEntry->action == args->action

                      && tailEntry->downTime == args->downTime

                      && tailEntry->pointerCoords[0].getAxisValue(AMOTION_EVENT_AXIS_X) == args->pointerCoords[0].getAxisValue(AMOTION_EVENT_AXIS_X)

                     && tailEntry->pointerCoords[0].getAxisValue(AMOTION_EVENT_AXIS_Y) == args->pointerCoords[0].getAxisValue(AMOTION_EVENT_AXIS_Y)

                      )

                      {

                           ALOGD("MTK debug notifyMotion drop motion event because of same x and y, action =0x%x ",args->action);

                            return;

                      }

           }

     }

    ALOGD("MTK debug notifyMotion not drop ");

    //add end

    if (!validateMotionEvent(args->action, args->pointerCount, args->pointerProperties)) {

        return;

    }

。。。。

｝

2、 在orientationManager.java中添加以下两个函数：

public void enableOrientationManager(){

    mOrientationListener.enable();

             }

         public void disableOrientationManager(){

    mOrientationListener.disable();

             }

3、 在AbstractGalleryActivity.java中添加以下两个函数：

 public void enableOrientationManager(){

   mOrientationManager.enableOrientationManager();

}

   public void disableOrientationManager(){

           mOrientationManager.disableOrientationManager();

   }

4、在apps/Camera/src/com/android/camera/Camera.java中添加如下代码：

public void enableOrientationListener() {

        mOrientationListener.enable();

    }

    public void disableOrientationListener() {

        mOrientationListener.disable();

    }

@Override

   public void enableOrientationManager(){

   super.enableOrientationManager();

}

   @Override

           public void disableOrientationManager(){

           super.disableOrientationManager();

   }

5、在apps/Camera/src/com/android/camera/actor/PhotoActor.java中：

5.1、在onBurstSaveDone（）中做如下修改:

 public void onBurstSaveDone() {

        if (!mCameraClosed && !mCamera.isImageCaptureIntent()) {

            mCamera.cancelContinuousShot();

            restartPreview(false);

        }

//add start

        mCamera.enableOrientationListener();

         mCamera.enableOrientationManager();

//add end

        mSavingPictures = false;

    }

5.2、在onShutterButtonLongPressed（）中做如下修改：

        mMemoryManager.initMemory();

        mContinuousShotPerformed = true;

        mCurrentShotsNum = 0;

//add start

        mCamera.disableOrientationListener();

       mCamera.disableOrientationManager();

//add end

        mCamera.applyContinousShot();

        mCamera.getThumbnailManager().setRefreshInterval(THUMBNAIL_REFRESH_CONTINUOUS);

        mCamera.getFocusManager().clearFocusOnContinuous();

        mCamera.getFocusManager().doSnap();
