android - Appium 服务器在运行测试时检测平台版本时出错

问题描述

我正在尝试在 appium 提供的测试应用程序上运行基本测试脚本。我正在使用带有 android 版本 8.1.0 的物理设备 (Nexus 6p)。这是我试图运行的代码（Node.js）：

const wdio = require("webdriverio");

const opts = {
  port: 4723,
  capabilities: {
    platformName: "Android",
    platformVersion: "8.1.0",
    deviceName: "Nexus 6P",
    app: "C:/Users/JH044350/Documents/Node/ApiDemos-debug.apk",
    automationName: "UiAutomator2"
  }
};

const client = wdio.remote(opts);

start = async function () {
  const elementId = await client.findElement("accessibility id", "TextField1"); client.elementSendKeys(elementId.ELEMENT, "Hello World!");
  const elementValue = await client.findElement("accessibility id", "TextField1");
  await client.getElementAttribute(elementValue.ELEMENT, "value").then((attr) => {
    assert.equal(attr, "Hello World!");
  });
}

运行代码并并排观察客户端和服务器后，会发生错误，这就是客户端部分中显示的内容：

这就是我在 appium 服务器日志上得到的信息：

主要错误似乎是无法找到手机的平台版本。当我运行他们正在尝试的代码时，adb shell getprop ro.build.version.release我得到了正确的输出（8.1.0）。我希望能得到任何帮助来引导我朝着正确的方向前进。

解决方案

此问题已通过降级 adb 版本解决。以上尝试使用 adb 版本 1.0.39 和 1.0.40。我从xda 开发人员那里下载了 adb 1.0.36并将文件复制并粘贴到我的平台工具文件夹并替换了重复项。再次运行测试后。它成功完成，没有问题。appium 似乎与新的 adb 不兼容。也许这是较新的 adb 版本中的新命令集，因为一些较旧的命令已被弃用。
