APP 定位防止页面未跳转导致元素无法定位 -android特有的wait_activity

wait_activity(self, activity, timeout, interval=1):

    等待指定的activity出现直到超时，interval为扫描间隔1秒

    即每隔几秒获取一次当前的activity
    
    android特有的

    返回的True 或 False

    :Agrs:

     - activity - 需等待的目标 activity

     - timeout - 最大超时时间，单位是s

     - interval - 循环查询时间

    用法:driver.wait_activity(‘.activity.xxx’,5,2)
