Answer 1

我找到了这个问题的答案。解决办法是删除 io.appium.uiautomator2.server 和 io.appium.uiautomator2.server.test 从设备。

确保 appium 服务器没有执行。

使用 USB 连接您的 android 设备，同时使用以下命令验证设备是否已正确连接:

adb devices

执行以下命令:

adb uninstall io.appium.uiautomator2.server
adb uninstall io.appium.uiautomator2.server.test

启动 appium 服务器

开始执行 appium 测试用例
