Appium：无法调用 start_activity 在 Android 7.0 上启动不同的应用程序答案

【问题标题】：Appium: Unable to call start_activity to launch a different app on Android 7.0Appium：无法调用 start_activity 在 Android 7.0 上启动不同的应用程序
【发布时间】：2018-01-26 11:21:43
【问题描述】：

我进行了移动测试，我在其中启动了我的应用程序并最终启动了 Chrome。为了启动 Chrome，我使用 app_package 和 app_activity 的参数调用 start_activity 函数。在运行 Android 5.0 和 6.0 的设备上，Chrome 可以正常启动。但是，在 Android 7.0 上它根本不会启动。

@@driver.start_activity(app_package: 'com.android.chrome',
                            app_activity: 'org.chromium.chrome.browser.ChromeTabbedActivity')

我收到以下错误：

更新：我已经能够通过 adb 使用以下命令启动 Chrome 来解决此问题：

adb shell am start -n #{app_package_activity[application]} 'com.android.chrome/com.google.android.apps.chrome.Main'
