【未解决】uiautomator2中如何获取到欢乐大作战游戏界面中的元素
期间，用代码：
AndroidAppMainActivity = "com.hldzz.dmw.MainActivity" d.app_start(AndroidAppMainActivity)
结果报错：

-》不过也从（开启了debug的）输出
d.info={'currentPackageName': 'com.tencent.tmgp.hldzzsyol', 'displayHeight': 1080, 'displayRotation': 3, 'displaySizeDpX': 851, 'displaySizeDpY': 393, 'displayWidth': 2135, 'productName': 'cepheus', 'sdkInt': 29, 'naturalOrientation': False}中看到了，此时正在运行的游戏的包名是：com.tencent.tmgp.hldzzsyol
所以再去搜搜：
com.tencent.tmgp.hldzzsyol
tencent hldzzsyol
hldzzsyol
应用包名：com.tencent.tmgp.pubgmhd
开发者名称：深圳市腾讯计算机系统有限公司
应用包名：com.tencent.tmgp.sgame
tmgp推测是：tencent mobile game Platform=腾讯移动游戏平台=腾讯手游平台
hldzzsyol推测是：欢乐大作战 手游 online（在线）
欢乐大作战 手游在线
欢乐大作战 腾讯
App Store 上的“欢乐大作战-挂机策略卡牌手游”
供应商 Guangzhou Eight Hundred Play Network Technology Co., Ltd
Copyright ©Eight Hundred Play Network Technology Co.,Ltd
欢乐大作战 腾讯游戏平台
欢乐大作战 腾讯移动游戏平台
腾讯移动游戏平台
腾讯移动游戏平台
果然是我猜测的：tencentmobilegames=腾讯移动游戏平台
还关注了 微信公众号，结果也没找到 欢乐大作战
算了，去试试
AndroidAppMainActivity = "com.tencent.tmgp.pubgmhd.MainActivity"
结果：
问题依旧：
uiautomator2.exceptions.BaseError: package "com.tencent.tmgp.pubgmhd.MainActivity" not found
看来要找到当前安装的这个游戏的apk才行了。
weditor中运行代码，也能看到同样信息
{'currentPackageName': 'com.tencent.tmgp.hldzzsyol', 'displayHeight': 1080, 'displayRotation': 3, 'displaySizeDpX': 851, 'displaySizeDpY': 393, 'displayWidth': 2135, 'productName': 'cepheus', 'sdkInt': 29, 'naturalOrientation': False}cepheus
最后通过微信中搜：
欢乐大作战
找到了其官方微信公众号
进入后
找到了下载
复制此条链接，在浏览器中打开即可下载~”

结果还是：
com.hldzz.dmw.MainActivity
啊，但是为何无法启动啊？
再去仔细看实例代码
d.app_start("com.example.hello_world")貌似com.example.hello_world
只是app的包名，而不是 mainActivity？？？
那试试
AndroidAppPackageName = "com.hldzz.dmw" d.app_start(AndroidAppPackageName)
结果：
找不到：
uiautomator2.exceptions.BaseError: package "com.hldzz.dmw" not found
后来发现之前的：
com.tencent.tmgp.pubgmhd.MainActivity
搞错了，应该是：
AndroidAppMainActivity = "com.tencent.tmgp.hldzzsyol.MainActivity" d.app_start(AndroidAppMainActivity)
结果：
uiautomator2.exceptions.BaseError: package "com.tencent.tmgp.hldzzsyol.MainActivity" not found
那再试试：
AndroidAppPackageName = "com.tencent.tmgp.hldzzsyol" d.app_start(AndroidAppPackageName)
结果：
是可以启动app的
【总结】
此处uiautomator2的官网文档
写的不够好
# 默认的这种方法是先通过atx-agent解析apk包的mainActivity，然后调用am start -n $package/$activity启动
d.app_start("com.example.hello_world")让我误以为是启动 package_name.MainActivity呢
结果搞错了，实际上是：
d.app_start(android_app_package_name)
而此处之所报错是因为：
网上下载到的，同名的游戏：欢乐大作战
和此处从微信中推荐游戏中下载到的，不是同一个app
-》估计是原游戏开发商，转到腾讯旗下了。
所以对应游戏的包名，从：
com.hldzz.dmw
变成了：
com.tencent.tmgp.hldzzsyol
所以此处用：
AndroidAppPackageName = "com.tencent.tmgp.hldzzsyol" d.app_start(AndroidAppPackageName)
即可正常启动游戏app了。
另外，此处如果不知道当前app的包名，除了去用aapt解析：
【已解决】分析安卓游戏app欢乐大作战的主页面mainActivity
即：
aapt dump badging xxx.apk
得到包名外，还可以：
用uiautomator2的代码：
import uiautomator2 as u2 d = u2.connect() print(d.info)
其中输出的
{'currentPackageName': 'com.tencent.tmgp.hldzzsyol' ... 中的currentPackageName的值，也就是当前app的包名。
另外：
同样代码，除了终端中运行，weditor中也可以运行，输出结果。
