以上都能过aidl 远程调用android.view.ViewRootImpl类中的服务

uiautomation中的findAccessibilityNodeInfosByViewId、findAccessibilityNodeInfosByText、performAccessibilityAction、findAccessibilityNodeInfoByAccessibilityId都由android.view.ViewRootImpl类的子类AccessibilityInteractionConnection来完成

android.view.ViewRootImpl类中有很类子类来完成控件的信息及完成按等动作
