无法运行在Android appium测试7.0

Question

我有问题，在Android上运行测试7.0实设备（的Nexus 6） Appium版本：1.6.3 操作系统：Windows 10 语言：Java的 Java客户端：4.1.2

有趣的是，当我插入任何Android 6设备（将platformVersion设置为6.0）时 - 测试运行没有问题。但是当我尝试在Android 7.0设备上运行它们时，出现错误。

这里是我的能力，在Android 7.0上运行：

DesiredCapabilities capabilities = new DesiredCapabilities(); 
capabilities.setCapability("deviceName", "Android"); 
capabilities.setCapability("browserName", "Android"); 
capabilities.setCapability("platformName", "Android"); 
capabilities.setCapability("platformVersion", "7.0"); 
capabilities.setCapability("fullReset", true); 
capabilities.setCapability("autoAcceptAlerts", true); 
capabilities.setCapability("newCommandTimeout", 0); 
capabilities.setCapability("app", "C:\Apk\xxx-release.apk"); 
capabilities.setCapability("appPackage", "com.xxx.android.vvm"); 
capabilities.setCapability("appActivity", "com.xxx.android.vvm.activity.Splash"); 

以下是IDE控制台输出日志：

看起来功能存在错误。但是，当我使用Android 6插入手机并将platformVersion设置为6.0时，所有测试运行都没有问题！

我将不胜感激任何帮助。

Answer 1

从设备中移除“解锁”和“Appium设置”应用程序 - Appium会自动安装这些应用程序。 （在我的原因中，将Android从版本6更新到版本7后，这些应用程序不兼容。

Answer 2

您可以发布Java客户端版本吗？

注意：尝试最新的稳定Java客户端版本。

https://mvnrepository.com/artifact/io.appium/java-client/4.1.2

Answer 3

删除“应用”功能，它试图在设备上安装的每一次。相反，在设备上手动安装应用程序并尝试。如果它不起作用，让我知道还有一个解决方案，但我建议你先试试。

Answer 4

由于错误日志显示

[INSTALL_FAILED_UPDATE_INCOMPATIBLE: Package io.appium.settings signatures do not match the previously installed version; 

通常这些错误出现，由于其设备上签署的发行版本，然后尝试部署在上面的调试版本。它陷入了一个无法完全卸载的无效状态。

因为这些原因，您的会话没有创建，为了避免这些请卸载设备上存在的应用程序，然后运行脚本。它应该工作。

希望这些帮助你。

Answer 5

如果遇到此错误，请使用Android Studio从测试设备中卸载所有工件。打开右侧的Gradle视图Android的工作室

打开：。应用程序>任务>安装和运行由双uninstallAll任务单击它
