小程序抓取UI树失败,提示hogging the main UI thread

An unknown server-side error occurred while processing the command. Original error: Timed out after 15622ms waiting for the root AccessibilityNodeInfo in the active window. Make sure the active window is not constantly hogging the main UI thread (e.g. the application is being idle long enough), so the accessibility manager could do its work
