【问题讨论】：

你在哪里指定目标网址？
@dha 编辑代码

标签： java eclipse selenium appium

【解决方案1】：

1-首先检查appium是否正在运行。

2- 如果是，您应该知道有时 Node.js 无法与 127.0.0.1:4723 对话，因此请改用 0.0.0.0:4723。请记住在代码 (DesiredCapabilities) 和 appium 设置中更改此设置。

3- 你应该保持如下代码结构。还需要使用这 3 个符号： (@BeforeMethod , @Test, @AfterMethod)

类似这样的：

 import <...>
    .
    .

    public class sample {  //this is the main class. You shouldn't define it as static or void so you must not have main methode
    //define variables you will be use during the test        
public AndroidDriver<MobileElement> driver;
        public WebDriverWait wait;
        public Dimension size;
        public String destDir;
        public DateFormat dateFormat;
        .
        .
        .
    //define the methodes you will be use during the test 
    public (swipe) {
    ... };
    public (takeScreenShot) {
    ...};

@BeforeMethod

    public void setup () throws MalformedURLException {
        DesiredCapabilities caps = new DesiredCapabilities();
        caps.setCapability("deviceName", "Galaxy S7 API 26");
        caps.setCapability("udid", "ce0217124184c72505"); //DeviceId from "adb devices" command
        caps.setCapability("platformName", "Android");
        caps.setCapability("platformVersion", "8.0");
        caps.setCapability("skipUnlock","true");
        caps.setCapability("appPackage", "app_packageName"); // Your app packageName
        caps.setCapability("appActivity","app_first_activity"); // The first activity of app. You can use "Apk Info2" application to find this
        caps.setCapability("noReset","false");
        driver = new AndroidDriver<MobileElement>(new URL("http://0.0.0.0:4723/wd/hub"),caps);
        wait = new WebDriverWait(driver, 10);
}

@Test
     public void test () throws Exception {

    //Test commands
    }

@AfterMethod

    public void teardown(){
        driver.quit();
    }

我希望这会有所帮助。

【讨论】：

【解决方案2】：

引用日志错误说：Original error: Cannot start the 'com.verizon.launcher.sdnasit' application.。我认为这是因为apps 功能具有误导性。

caps.setCapability("appPackage", "com.verizon.launcher.sdnasit");
caps.setCapability("appActivity", "com.verizon.launcher.webview.WebActivity");

也许这才是真正的能力：

caps.setCapability("appPackage", "com.verizon.launcher.sdnasit");
caps.setCapability("appActivity", ".webview.WebActivity");

为了确定，here 如何知道appPackage 和appActivity。
