有段时间没有维护这个项目了（可能有两年了），但是最近工作需要又重新研究一下Android原生自动化，当然又调研了Appium，对比下来一看，发现uiautomator2这个项目的运行速度是真的好快，从检测元素到点击，都是毫秒级的，代码也比较好理解。真是没想到以前竟然写出了这么神奇的项目，这么好的项目怎么能让它落灰呢，得好好整一整，一些垃圾代码清理清理。所以项目版本从2.x.x升级到了3.x.x
还在用2.x.x版本的用户，可以先看一下2to3 再决定是否要升级3.x.x （我个人还是非常建议升级的）
2到3毕竟是大版本升级，很多的函数删掉了。首先删掉的就是atx-agent，其次还有一堆atx-agent相关的函数。废弃的功能比如init.
各种依赖库的版本号
UiAutomator是Google提供的用来做安卓自动化测试的一个Java库，基于Accessibility服务。功能很强，可以对第三方App进行测试，获取屏幕上任意一个APP的任意一个控件属性，并对其进行任意操作，但有两个缺点：1. 测试脚本只能使用Java语言 2. 测试脚本要打包成jar或者apk包上传到设备上才能运行。
我们希望测试逻辑能够用Python编写，能够在电脑上运行的时候就控制手机。这里要非常感谢 Xiaocong He (@xiaocong)，他将这个想法实现了出来（见xiaocong/uiautomator），原理是在手机上运行了一个http rpc服务，将uiautomator中的功能开放出来，然后再将这些http接口封装成Python库。
因为xiaocong/uiautomator这个库，已经很久不见更新。所以我们直接fork了一个版本，为了方便做区分我们就在后面加了个2 openatx/uiautomator2,对应的Android包源码我也fork了一份，openatx/android-uiautomator-server
除了对原有的库的bug进行了修复，还增加了很多新的Feature。主要有以下部分：
这里要先说明下，因为经常有很多人问 openatx/uiautomator2 并不支持iOS测试，需要iOS自动化测试，可以转到这个库 openatx/facebook-wda。
PS: 这个库
https://github.com/NeteaseGame/ATX目前已经不维护了，请尽快更换。
这里有一份快速参考，适合已经入门的人 QUICK REFERENCE GUIDE，欢迎多提意见。
先准备一台（不要两台）开启了开发者选项的安卓手机，连接上电脑，确保执行adb devices可以看到连接上的设备。
运行pip3 install -U uiautomator2 安装uiautomator2
命令行运行python打开python交互窗口。然后将下面的命令输入到窗口中。
import uiautomator2 as u2
d = u2.connect() # connect to device
print(d.info)
这时看到类似下面的输出，就可以正式开始用我们这个库了。因为这个库功能太多，后面还有很多的内容，需要慢慢去看 ....
{'currentPackageName': 'net.oneplus.launcher', 'displayHeight': 1920, 'displayRotation': 0, 'displaySizeDpX': 411, 'displaySizeDpY': 731, 'displayWidth': 1080, 'productName': 'OnePlus5', '
screenOn': True, 'sdkInt': 27, 'naturalOrientation': True}
另外为了保持稳定，还需要开启小黄车的悬浮窗权限。参考文章 py-uiautomator2通过悬浮窗让服务长时间可用
一般情况下都会成功，不过也可能会有意外。可以加QQ群反馈问题(群号在最上面），群里有很多大佬可以帮你解决问题。

This part showcases how to perform app management
We only support installing an APK from a URL
d.app_install('http://some-domain.com/some.apk')
# 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")
# 使用 monkey -p com.example.hello_world -c android.intent.category.LAUNCHER 1 启动
# 这种方法有个副作用，它自动会将手机的旋转锁定给关掉
d.app_start("com.example.hello_world", use_monkey=True) # start with package name
# 通过指定main activity的方式启动应用，等价于调用am start -n com.example.hello_world/.MainActivity
d.app_start("com.example.hello_world", ".MainActivity")
# equivalent to `am force-stop`, thus you could lose data
d.app_stop("com.example.hello_world")
# equivalent to `pm clear`
d.app_clear('com.example.hello_world')
# stop all

# same as
# adb shell am start -a android.intent.action.VIEW -d "appname://appnamehost"
This part showcases how to perform common device operations:
Run a short-lived shell command with a timeout protection. (Default timeout 60s)
Note: timeout support require atx-agent >=0.3.3
adb_shell function is deprecated. Use shell instead.
Simple usage
output, exit_code = d.shell("pwd", timeout=60) # timeout 60s (Default)
# output: "/\n", exit_code: 0
# Similar to command: adb shell pwd
# Since `shell` function return type is `namedtuple("ShellResponse", ("output", "exit_code"))`
# so we can do some tricks
output = d.shell("pwd").output
exit_code = d.shell("pwd").exit_code
The first argument can be list. for example
output, exit_code = d.shell(["ls", "-l"])
# output: "/....", exit_code: 0
This returns a string for stdout merged with stderr.
If the command is a blocking command, shell will also block until the command is completed or the timeout kicks in. No partial output will be received during the execution of the command. This API is not suitable for long-running commands. The shell command given runs in a similar environment of adb shell, which has a Linux permission level of adb or shell (higher than an app permission).
Run a long-running shell command (Removed)
Session represent an app lifecycle. Can be used to start app, detect app crash.
Launch and close app
sess = d.session("com.netease.cloudmusic") # start 网易云音乐
sess.close() # 停止网易云音乐
sess.restart() # 冷启动网易云音乐
Use python with to launch and close app
with d.session("com.netease.cloudmusic") as sess:
sess(text="Play").click()
Attach to the running app
# launch app if not running, skip launch if already running
sess = d.session("com.netease.cloudmusic", attach=True)
Detect app crash
# When app is still running
sess(text="Music").click() # operation goes normal
# If app crash or quit
sess(text="Music").click() # raise SessionBrokenError
# other function calls under session will raise SessionBrokenError too
# check if session is ok.
# Warning: function name may change in the future
sess.running() # True or False

Touch and drap (Beta)
这个接口属于比较底层的原始接口，感觉并不完善，不过凑合能用。注：这个地方并不支持百分比
d.touch.down(10, 10) # 模拟按下
time.sleep(.01) # down 和 move 之间的延迟，自己控制
d.touch.move(15, 15) # 模拟移动
d.touch.up(10, 10) # 模拟抬起
Note: click, swipe, drag operations support percentage position values. Example:
d.long_click(0.5, 0.5) means long click center of screen
Retrieve/Set device orientation
The possible orientations:
natural or nleft or lright or rupsidedown or u (can not be set)# retrieve orientation. the output could be "natural" or "left" or "right" or "upsidedown"
orientation = d.orientation
# WARNING: not pass testing in my TT-M1
# set orientation and freeze rotation.
# notes: setting "upsidedown" requires Android>=4.3.
d.set_orientation('l') # or "left"
d.set_orientation("l") # or "left"
d.set_orientation("r") # or "right"
d.set_orientation("n") # or "natural"
Freeze/Un-freeze rotation
# freeze rotation
d.freeze_rotation()
# un-freeze rotation
d.freeze_rotation(False)
Take screenshot
# take screenshot and save to a file on the computer, require Android>=4.2.
d.screenshot("home.jpg")
# get PIL.Image formatted images. Naturally, you need pillow installed first
image = d.screenshot() # default format="pillow"
image.save("home.jpg") # or home.png. Currently, only png and jpg are supported
# get opencv formatted images. Naturally, you need numpy and cv2 installed first
import cv2
image = d.screenshot(format='opencv')
cv2.imwrite('home.jpg', image)
# get raw jpeg data
imagebin = d.screenshot(format='raw')
open("some.jpg", "wb").write(imagebin)
Dump UI hierarchy
# get the UI hierarchy dump content
xml = d.dump_hierarchy()
# compressed=True: include not import nodes
# pretty: format xml
# max_depth: limit xml depth, default 50
xml = d.dump_hierarchy(compressed=False, pretty=False, max_depth=50)
Open notification or quick settings
d.open_notification()
d.open_quick_settings()
Selector is a handy mechanism to identify a specific UI object in the current window.
# Select the object with text 'Clock' and its className is 'android.widget.TextView'
d(text='Clock', className='android.widget.TextView')
Selector supports below parameters. Refer to UiSelector Java doc for detailed information.
text, textContains, textMatches, textStartsWithclassName, classNameMatchesdescription, descriptionContains, descriptionMatches, descriptionStartsWithcheckable, checked, clickable, longClickablescrollable, enabled,focusable, focused, selectedpackageName, packageNameMatchesresourceId, resourceIdMatchesindex, instancechildren
# get the children or grandchildren
d(className="android.widget.ListView").child(text="Bluetooth")
siblings
# get siblings
d(text="Google").sibling(className="android.widget.ImageView")
children by text or description or instance
# get the child matching the condition className="android.widget.LinearLayout"
# and also its children or grandchildren with text "Bluetooth"
d(className="android.widget.ListView", resourceId="android:id/list") \
.child_by_text("Bluetooth", className="android.widget.LinearLayout")
# get children by allowing scroll search
d(className="android.widget.ListView", resourceId="android:id/list") \
.child_by_text(
"Bluetooth",
allow_scroll_search=True,
className="android.widget.LinearLayout"
)
child_by_description is to find children whose grandchildren have
the specified description, other parameters being similar to child_by_text.
child_by_instance is to find children with has a child UI element anywhere
within its sub hierarchy that is at the instance specified. It is performed
on visible views without scrolling.
See below links for detailed information:
getChildByDescription, getChildByText, getChildByInstancegetChildByDescription, getChildByText, getChildByInstanceAbove methods support chained invoking, e.g. for below hierarchy
<node index="0" text="" resource-id="android:id/list" class="android.widget.ListView" ...>
<node index="0" text="WIRELESS & NETWORKS" resource-id="" class="android.widget.TextView" .../>
<node index="1" text="" resource-id="" class="android.widget.LinearLayout" ...>
<node index="1" text="" resource-id="" class="android.widget.RelativeLayout" ...>
<node index="0" text="Wi‑Fi" resource-id="android:id/title" class="android.widget.TextView" .../>
</node>
<node index="2" text="ON" resource-id="com.android.settings:id/switchWidget" class="android.widget.Switch" .../>
</node>
...
</node>
To click the switch widget right to the TextView 'Wi‑Fi', we need to select the switch widgets first. However, according to the UI hierarchy, more than one switch widgets exist and have almost the same properties. Selecting by className will not work. Alternatively, the below selecting strategy would help:
d(className="android.widget.ListView", resourceId="android:id/list") \
.child_by_text("Wi‑Fi", className="android.widget.LinearLayout") \
.child(className="android.widget.Switch") \
.click()
relative positioning
Also we can use the relative positioning methods to get the view: left, right, top, bottom.
d(A).left(B), selects B on the left side of A.d(A).right(B), selects B on the right side of A.d(A).up(B), selects B above A.d(A).down(B), selects B under A.So for above cases, we can alternatively select it with:
## select "switch" on the right side of "Wi‑Fi"
d(text="Wi‑Fi").right(className="android.widget.Switch").click()
Multiple instances
Sometimes the screen may contain multiple views with the same properties, e.g. text, then you will have to use the "instance" property in the selector to pick one of qualifying instances, like below:
d(text="Add new", instance=0) # which means the first instance with text "Add new"
In addition, uiautomator2 provides a list-like API (similar to jQuery):
# get the count of views with text "Add new" on current screen
d(text="Add new").count
# same as count property
len(d(text="Add new"))
# get the instance via index
d(text="Add new")[0]
d(text="Add new")[1]
...
# iterator
for view in d(text="Add new"):
view.info # ...
Notes: when using selectors in a code block that walk through the result list, you must ensure that the UI elements on the screen keep unchanged. Otherwise, when Element-Not-Found error could occur when iterating through the list.
Check if the specific UI object exists
d(text="Settings").exists # True if exists, else False
d.exists(text="Settings") # alias of above property.
# advanced usage
d(text="Settings").exists(timeout=3) # wait Settings appear in 3s, same as .wait(3)
Retrieve the info of the specific UI object
d(text="Settings").info
Below is a possible output:
{ u'contentDescription': u'',
u'checked': False,
u'scrollable': False,
u'text': u'Settings',
u'packageName': u'com.android.launcher',

# drag the UI object to (the center position of) another UI object, in 0.25 second
d(text="Settings").drag_to(text="Clock", duration=0.25)
Swipe from the center of the UI object to its edge
Swipe supports 4 directions:
d(text="Settings").swipe("right")
d(text="Settings").swipe("left", steps=10)
d(text="Settings").swipe("up", steps=20) # 1 steps is about 5ms, so 20 steps is about 0.1s

Supports two gestures:
In, from edge to centerOut, from center to edge# notes : pinch can not be set until Android 4.3.
# from edge to center. here is "In" not "in"
d(text="Settings").pinch_in(percent=100, steps=10)
# from center to edge
d(text="Settings").pinch_out()
Wait until the specific UI appears or disappears
# wait until the ui object appears

目前的这个watch_context是用threading启动的，每2s检查一次 目前还只有click这一种触发操作
with d.watch_context() as ctx:
# 当同时出现 （立即下载 或 立即更新）和 取消 按钮的时候，点击取消
ctx.when("^立即(下载|更新)").when("取消").click()
ctx.when("同意").click()
ctx.when("确定").click()
# 上面三行代码是立即执行完的，不会有什么等待
ctx.wait_stable() # 开启弹窗监控，并等待界面稳定（两个弹窗检查周期内没有弹窗代表稳定）
# 使用call函数来触发函数回调
# call 支持两个参数，d和el，不区分参数位置，可以不传参，如果传参变量名不能写错
# eg: 当有元素匹配仲夏之夜，点击返回按钮
ctx.when("仲夏之夜").call(lambda d: d.press("back"))
ctx.when("确定").call(lambda el: el.click())
# 其他操作
# 为了方便也可以使用代码中默认的弹窗监控逻辑
# 下面是目前内置的默认逻辑，可以加群at群主，增加新的逻辑，或者直接提pr
# when("继续使用").click()
# when("移入管控").when("取消").click()
# when("^立即(下载|更新)").when("取消").click()
# when("同意").click()
# when("^(好的|确定)").click()
with d.watch_context(builtin=True) as ctx:
# 在已有的基础上增加
ctx.when("@tb:id/jview_view").when('//*[@content-desc="图片"]').click()
# 其他脚本逻辑
另外一种写法
ctx = d.watch_context()
ctx.when("设置").click()
ctx.wait_stable() # 等待界面不在有弹窗了
ctx.close()
更推荐用WatchContext 写法更简洁一些
You can register watchers to perform some actions when a selector does not find a match.
2.0.0之前使用的是 uiautomator-jar库中提供的[Watcher]((http://developer.android.com/tools/help/uiautomator/UiWatcher.html)方法，但在实践中发现一旦uiautomator连接失败重启了，所有的watcher配置都是丢失，这肯定是无法接受的。
所以目前采用了后台运行了一个线程的方法(依赖threading库），然后每隔一段时间dump一次hierarchy，匹配到元素之后执行相应的操作。
用法举例
注册监控
# 常用写法，注册匿名监控
d.watcher.when("安装").click()
# 注册名为ANR的监控，当出现ANR和Force Close时，点击Force Close
d.watcher("ANR").when(xpath="ANR").when("Force Close").click()
# 其他回调例子
d.watcher.when("抢红包").press("back")
d.watcher.when("//*[@text = 'Out of memory']").call(lambda d: d.shell('am force-stop com.im.qq'))
# 回调说明
def click_callback(d: u2.Device):
d.xpath("确定").click() # 在回调中调用不会再次触发watcher
d.xpath("继续").click() # 使用d.xpath检查元素的时候，会触发watcher（目前最多触发5次）
# 开始后台监控
d.watcher.start()
监控操作
# 移除ANR的监控
d.watcher.remove("ANR")
# 移除所有的监控
d.watcher.remove()
# 开始后台监控
d.watcher.start()
d.watcher.start(2.0) # 默认监控间隔2.0s
# 强制运行所有监控
d.watcher.run()
# 停止监控
d.watcher.stop()
# 停止并移除所有的监控，常用于初始化
d.watcher.reset()
另外文档还是有很多没有写，推荐直接去看源码watcher.py
u2.HTTP_TIMEOUT = 60 # 默认值60s, http默认请求超时时间
其他的配置，目前已大部分集中到 d.settings 中，根据后期的需求配置可能会有增减。
print(d.settings)
{'operation_delay': (0, 0),
'operation_delay_methods': ['click', 'swipe'],
'wait_timeout': 20.0}
# 配置点击前延时0.5s，点击后延时1s
d.settings['operation_delay'] = (.5, 1)
# 修改延迟生效的方法
# 其中 double_click, long_click 都对应click
d.settings['operation_delay_methods'] = ['click', 'swipe', 'drag', 'press']
d.settings['wait_timeout'] = 20.0 # 默认控件等待时间（原生操作，xpath插件的等待时间）
d.settings['max_depth'] = 50 # 默认50，限制dump_hierarchy返回的元素层级
对于随着版本升级，设置过期的配置时，会提示Deprecated，但是不会抛异常。
>>> d.settings['click_before_delay'] = 1
[W 200514 14:55:59 settings:72] d.settings[click_before_delay] deprecated: Use operation_delay instead
uiautomator恢复方式设置
细心的你可能发现，实际上手机安装了两个APK，一个在前台可见（小黄车）。一个包名为com.github.uiautomator.test在后台不可见。这两个apk使用同一个证书签名的。
不可见的应用实际上是一个测试包，包含有所有的测试代码，核心的测试服务也是通过其启动的。
但是运行的时候，系统却需要那个小黄车一直在运行（在后台运行也可以）。一旦小黄车应用被杀，后台运行的测试服务也很快的会被杀掉。就算什么也不做，应用应用在后台，也会很快被系统回收掉。（这里希望高手指点一下，如何才能不依赖小黄车应用，感觉理论上是可以的，但是目前我还不会）。
让小黄车在后台运行有两种方式，一种启动应用后，放到后台（默认）。另外通过am startservice启动一个后台服务也行。
通过 d.settings["uiautomator_runtest_app_background"] = True 可以调整该行为。True代表启动应用，False代表启动服务。
UiAutomator中的超时设置(隐藏方法)
>> d.jsonrpc.getConfigurator()
{'actionAcknowledgmentTimeout': 500,
'keyInjectionDelay': 0,
'scrollAcknowledgmentTimeout': 200,
'waitForIdleTimeout': 0,
'waitForSelectorTimeout': 0}
>> d.jsonrpc.setConfigurator({"waitForIdleTimeout": 100})
{'actionAcknowledgmentTimeout': 500,
'keyInjectionDelay': 0,
'scrollAcknowledgmentTimeout': 200,
'waitForIdleTimeout': 100,
'waitForSelectorTimeout': 0}
为了防止客户端程序响应超时，waitForIdleTimeout和waitForSelectorTimeout目前已改为0
Refs: Google uiautomator Configurator
这种方法通常用于不知道控件的情况下的输入。
# 目前采用从剪贴板粘贴的方式输入
d.send_keys("你好123abcEFG")
d.send_keys("你好123abcEFG", clear=True)
d.clear_text() # 清除输入框所有内容
d.send_action() # 根据输入框的需求，自动执行回车、搜索等指令, Added in version 3.1
# 也可以指定发送的输入法action, eg: d.send_action("search") 支持 go, search, send, next, done, previous
print(d.current_ime()) # 获取当前输入法ID
更多参考: IME_ACTION_CODE
print(d.last_toast) # get last toast, if not toast return None
d.clear_toast()
Fixed in version 3.2.0
Java uiautoamtor中默认是不支持xpath的，所以这里属于扩展的一个功能。速度不是这么的快。
For example: 其中一个节点的内容
<android.widget.TextView
index="2"
text="05:19"
resource-id="com.netease.cloudmusic:id/qf"
package="com.netease.cloudmusic"
content-desc=""
checkable="false" checked="false" clickable="false" enabled="true" focusable="false" focused="false"
scrollable="false" long-clickable="false" password="false" selected="false" visible-to-user="true"
bounds="[957,1602][1020,1636]" />
xpath定位和使用方法
有些属性的名字有修改需要注意
description -> content-desc
resourceId -> resource-id
常见用法
# wait exists 10s
d.xpath("//android.widget.TextView").wait(10.0)
# find and click
d.xpath("//*[@content-desc='分享']").click()
# check exists
if d.xpath("//android.widget.TextView[contains(@text, 'Se')]").exists:
print("exists")
# get all text-view text, attrib and center point
for elem in d.xpath("//android.widget.TextView").all():
print("Text:", elem.text)
# Dictionary eg:
# {'index': '1', 'text': '999+', 'resource-id': 'com.netease.cloudmusic:id/qb', 'package': 'com.netease.cloudmusic', 'content-desc': '', 'checkable': 'false', 'checked': 'false', 'clickable': 'false', 'enabled': 'true', 'focusable': 'false', 'focused': 'false','scrollable': 'false', 'long-clickable': 'false', 'password': 'false', 'selected': 'false', 'visible-to-user': 'true', 'bounds': '[661,1444][718,1478]'}
print("Attrib:", elem.attrib)
# Coordinate eg: (100, 200)
print("Position:", elem.center())

视频录制(废弃)，使用scrcpy来代替吧
这里没有使用手机中自带的screenrecord命令，是通过获取手机图片合成视频的方法，所以需要安装一些其他的依赖，如imageio, imageio-ffmpeg, numpy等 因为有些依赖比较大，推荐使用镜像安装。直接运行下面的命令即可。
pip3 install -U "uiautomator2[image]" -i https://pypi.doubanio.com/simple
使用方法
d.screenrecord('output.mp4')
time.sleep(10)
# or do something else
d.screenrecord.stop() # 停止录制后，output.mp4文件才能打开
录制的时候也可以指定fps（当前是20），这个值是率低于minicap输出图片的速度，感觉已经很好了，不建议你修改。
from uiautomator2 import enable_pretty_logging
enable_pretty_logging()
Or
logger = logging.getLogger("uiautomator2")
# setup logger
Python程序退出了，UiAutomation就退出了。 不过也可以通过接口的方法停止服务
d.stop_uiautomator()
