报错

An unknown server-side error occurred while processing the command. Original error: io.appium.uiautomator2.common.exceptions.UiAutomator2Exception: Timed out after 15508ms 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

那个地方不对呢？

需要注意些什么？

得重新获取元素才能执行
