环境
appium1.6.3
jdk1.8
java-client 5.0.0-BETA3
selenium 3.0.1

测试代码：

protected AndroidDriver driver;
@Parameters({ "serverIP","port", "platformName","udid",
"appPackage", "appActivity" })
@BeforeTest
public void setUp(String serverIP,String port,String platformName,String udid,
String appPackage,String appActivity) throws Exception {

DesiredCapabilities capabilities = new DesiredCapabilities();
capabilities.setCapability(CapabilityType.BROWSER_NAME, "");
capabilities.setCapability("platformName", platformName);
capabilities.setCapability("deviceName", udid);
capabilities.setCapability("udid", udid);
capabilities.setCapability("platformVersion", "6.0");
capabilities.setCapability("unicodeKeyboard", true);
capabilities.setCapability("resetKeyboard", true);
capabilities.setCapability("noReset", true);
capabilities.setCapability("noSign", true);
capabilities.setCapability("appPackage", appPackage);
capabilities.setCapability("appActivity", appActivity);
capabilities.setCapability("automationName","uiautomator2");
driver = new AndroidDriver(new URL("http://" + serverIP + ":" + port + "/wd/hub"),capabilities);
}

增加这句 capabilities.setCapability("automationName","uiautomator2");，无法启动 app 测试，也没办法安装 io.appium.uiautomator2.server 和
io.appium.uiautomator2.server.test 这两个 apk，去掉又正常

部分报错信息如下：

大家有没有遇到过，以上还需要配置什么，我就上面这种环境，加了 capabilities.setCapability("automationName","uiautomator2");，然后启动 appium,然后进行测试，是否少什么配置？关于兼容性我考虑过了 appium1.6.4 也试过了,java-client 和 selenium 都试了好几个版本
