试过，一样的
Original error: The instrumentation process cannot be initialized. Make sure the application under test does not crash and investigate the logcat output.

我用的逍遥，android7

{
"platformName": "Android",
"deviceName": "samsung SM-G9550",
"appPackage": "com.p1.mobile.aaa",
"appActivity": "com.p1.mobile.xxx",
"platformVersion": "7.1.2",
"automationName": "UiAutomator1"
}
在配置里我加了句"automationName": "UiAutomator1"
如果不加的话，就这样：
An unknown server-side error occurred while processing the command. Original error: The instrumentation process cannot be initialized. Make sure the application under test does not crash and investigate the logcat output.

百度找了找，发现都是 用苹果电脑 +iphone 的。

我用 windows+ipad 可以吗？

数字是变化的，所以要用 XX 查找

driver.find_element_by_android_uiautomator('new UiSelector().text("XX"")')

selenium.common.exceptions.NoSuchElementException: Message: An element could not be located on the page using the given search parameters.

命令行下取 dump .xml 没问题，播放和暂停都可以。
虽然有时也会取不到。

但在我在 python 里执行命令行，就永远取不到了。

我看了你说的暂停那个，但在代码里总是不行。搜了几天也没有提到解决办法的，哎

用你图里的工具和 uiautomatorviewer 是都能找到元素的。
但是写在代码 里跑就找不到了。。

我试你说的暂停那个先。

=============================================
暂停视频也是不行

我试过命令行下用 adb 里用命令取 xml
不管视频播放停止都可以。。

而且还能找到我要的那个元素

模拟器不息，
延迟几秒都没用

time.sleep(70)

这好像也只是提示没找到元素。。。
我没太看出别的异常。我的分析对吗？

试过等待，昨晚发现 page_source 没有这个元素。
找别的元素的时候，page_source 里面都有。到这个就没了。
不明白怎么回事？

嗯。昨天晚上试过，page_source 也没有这个元素
然后搜了半天，也没找到什么办法

就是 douyin，刚好学习，就用这个挺火的练习

你说的内嵌 js 或 动态获取，要用什么方法确定？

就是这个（刚好截时是个美女图，涂掉吧）
红框那个

这上打错了。试了，找到了

好的

不是这个。。。

开梯子都没下来。

呃。。activity 写错了。
我没找到安卓 桌面的 activity 叫什么。这个要怎么查

这跟使用方式有什么关系

你使用的在熟练，也有出错又有明白的时候。
