Question

我在Android 7.0真实设备（Nexus 6）上运行测试时遇到问题 Appium版本：1.6.3 操作系统：Windows 10 语言：Java 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设备上运行它时，我收到错误。

以下是我在Android 7.0上运行的功能：

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控制台输出中的日志：

似乎功能出错。但是，当我使用Android 6插入手机并将platformVersion设置为6.0时，所有测试都运行没有问题！

我将不胜感激。

Answer 1

删除＆＃34;解锁＆＃34;和＆＃34; Appium设置＆＃34;来自设备的应用程序 - 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：尝试使用最新的稳定Java客户端版本。

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

Answer 3

删除尝试每次在设备上安装的“应用”功能。而是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，但我建议你先尝试一下。

Answer 4

错误日志显示

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

通常这些错误是由于在设备上签署了发布版本，然后尝试在顶部部署调试版本。它被卡在一个无法完全卸载的无效状态。

由于这些原因，您的会话未创建，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。它应该可以工作。

希望这些可以帮助你。

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Android studio右侧的Gradle视图。

打开：应用＆gt;任务＆gt;双击安装并运行uninstallAll任务

无法在Android 7.0上运行appium测试
