android id标签,appium1.7.1，android7.0+ 上，元素 ID 识别不了

appium 版本 1.7.1，python 环境，使用的 appiumlibrary 库，版本如下：

页面上的元素 “关闭易信首页提示” 在 automator viewer 里面能找到，且在 android5.0 的手机上控件能正常识别

但是在 android7.0、android8.0 的手机上，不管使用 ID 还是 name 定位的方式都找不到。appium 的 log 如下：

这个页面的其他元素，在 android7.0、8.0 上能正常识别，只有这个元素，

看了下 appiumlibrary 中 click_element 这个方法，写的是：

def click_element(self, locator):

"""Click element identified by `locator`.

Key attributes for arbitrary elements are `index` and `name`. See

`introduction` for details about locating elements.

"""

self._info("Clicking element '%s'." % locator)

self._element_find(locator, True, True).click()

求各位指点指点
