Appium session ，找不到连接的 Android 设备。在eclipse中显示错误

如果有人知道如何修复请告诉我。

**Junit 代码:-**

    import static org.junit.Assert.*;
    import java.io.File;
    import java.net.MalformedURLException;
    import java.net.URL;
    import org.junit.Test;
    import org.openqa.selenium.remote.DesiredCapabilities;
    import io.appium.java_client.android.AndroidDriver;
    import io.appium.java_client.remote.MobileCapabilityType;
    import io.appium.java_client.remote.MobilePlatform;

    public class desiredCapab {

        @Test
        public void test() throws MalformedURLException {

            File appDir = new File("C:\\Eclipse-Neon\\Project\\AppiumT\\Apk\\");

                File app = new File (appDir, "WhatsApp.apk");


            DesiredCapabilities cap = new DesiredCapabilities();
            cap.setCapability(MobileCapabilityType.PLATFORM_NAME,MobilePlatform.ANDROID);
cap.setCapability(MobileCapabilityType.DEVICE_NAME, "Android Emulator");
cap.setCapability(MobileCapabilityType.APP, app.getAbsolutePath());

AndroidDriver driver = new AndroidDriver(new URL ("http://127.0.0.1:4723/wd/hub"), cap);

            //{"address":"127.0.0.1","logNoColors":true,"platformName":"Android","platformVersion":"23","automationName":"Appium"}
        }
    }

Eclipse Junit 错误:-

最佳答案

出现上述错误的原因是，无法找到任何设备或 AVD 进行连接。您的错误消息中的以下几行显示了这一点:

> info: [debug] Trying to find a connected android device
> info: [debug] Getting connected devices...
> info: [debug] executing cmd: C:\Users\bizBoxChat\AppData\Local\Android\sdk\platform-tools\adb.exe devices
> info: [debug] 0 device(s) connected
> info: [debug] Could not find devices, restarting adb server...

> info: [debug] Error: Could not find a connected Android device.

仅在 AVD 管理器中创建 AVD 是不够的。它必须启动并运行(已启动并准备就绪)。为此，请在您的 AVD 管理器中选择任何 AVD，然后单击“开始”按钮。让 AVD 启动。等待。 (这类似于打开真实设备。) 或者，需要连接一些真实的设备。在该设备中，“开发者选项”应该是开启的。 “USB 调试”应该打开。

转到命令提示符并运行以下命令:

adb devices

预期输出:某些设备或 AVD 应显示为已连接。 一旦您看到任何设备或 AVD 已连接并重试，您的问题就会得到解决。

注意: 在命令窗口中运行“adb devices”命令时，如果您看到类似“abd.exe 是无法识别的内部或外部命令或批处理文件...”的消息，那么您需要在路径中包含 adb.exe。您可以在环境变量中添加它的路径，或者在运行“adb devices”之前简单地运行以下命令:

set path=%PATH%;"D:\AndroidSDK\platform-tools"

请注意，adb.exe 文件在我的 PC 上的 platform-tools 文件夹中，在 Android SDK 文件夹中。您需要修改此路径，因为它在您的 PC 上。
