Appium 关于 activity 的获取函数与 app 的 reset

付兰 · March 17, 2016 · Last by 付兰 replied at March 19, 2016 · 1454 hits

测试环境：appium1.4.16+python3.5+android5.1
1.网上 api 中获取 activity 用法为：driver.current_activity(),结果使用时出现错误

try:
    current=driver.current_activity()
    print(current)
except Exception as e:
    print("[Error]: ",e)
driver.quit()

错误信息：

console 输出错误信息为：

[Error]:  'str' object is not callable

解决办法：目前群里有人帮我解决了，将括号去掉即可，就是 current=driver.current_activity
但是，为什么要去掉括号，有人能稍微解答一下吗

2、关闭 app 使用 driver.close_app() ,启动 app 使用 driver.launch_app（）都是对的，但是使用重启 app 就出现错误了

#coding:utf-8 print(driver.current_activity())
from appium import webdriver
import time
from appium.webdriver.common.touch_action import TouchAction
from selenium.webdriver.common.touch_actions import TouchActions
desired_caps = {}
desired_caps['platformName'] = 'Android'  
desired_caps['platformVersion'] = '5.1'
desired_caps['deviceName'] = '0123456789ABCDEF'
desired_caps['appPackage'] = 'com.android.gallery3d'
desired_caps['appActivity'] = 'com.android.camera.CameraLauncher'
driver = webdriver.Remote('http://localhost:4723/wd/hub', desired_caps)
time.sleep(2)
print('开始执行')
try:
    driver.reset()
except Exception as e:
    print("[Error]: ",e)
print('执行完成')
driver.quit()

console 输出的：

[Error]:  Message: An unknown server-side error occurred while processing the command.

3、有没有什么方法可以在运行代码出错后可以快速的关掉 appium 的所谓的 session 吗（因为改了代码想马上运行时会提示有一个 sesion 正在运行），由于没办法，把昨晚刚学到的 try except 用上了，谢谢！

日志和代码尽量都适用 markdown，不要用图片。谢谢

将括号去掉即可，就是 current=driver.current_activity,但是，为什么要去掉括号，有人能稍微解答一下吗
建议你可以看下源码。因为这个方法 current_activity 是 webdriver 的自身属性。例如：

    @property
    def current_url(self):
        """
        Gets the URL of the current page.

        :Usage:
            driver.current_url
        """
        return self.execute(Command.GET_CURRENT_URL)['value']
# @property 装饰器可以将python定义的函数“当做”属性直接访问。

所以不需要带上 ()。直接调用就可以了。
ps:我是看的 selenium 的源码哦，你看下 appium 应该也是一样的 o(∩_∩) o 。

#2 楼 @xie_0723 谢谢，这个是这样的：


@property
def current_activity(self):
    """Retrieves the current activity on the device.
    """
    return self.execute(Command.GET_CURRENT_ACTIVITY)['value']

之前用过 selendroid 模式？现在手机上的 app 是 selendroid 模式下安装的？

付兰 #11 · March 18, 2016 Author

#10 楼 @sanlengjingvv 我的设置是 appium 啊

info: [debug] Running old fashion reset (reinstall)

貌似要重新安装，你加上这个试一试
desired_caps['app'] = '/abs/path/to/my.apk'

看下这个 issue 的评论
reset() breaks Appium if the App has been launched with "no_reset=true"

付兰 #13 · March 19, 2016 Author

#12 楼 @sanlengjingvv 是的，如果不设置路径的话，我 no reset 不勾选上也可以，我明天整理一下，谢谢
