无法使用appium在emulator中访问android应用程序

Question

我正在使用SeleniumJavaJAR版本：3.4.0Appium，桌面版本：1.4.13.1Java客户端版本：5.0.0-BETA9

代码和所需的功能是：

import org.openqa.selenium.remote.DesiredCapabilities;
import java.io.File;
import java.net.MalformedURLException;
import java.net.URL;
import java.util.concurrent.TimeUnit;

import io.appium.java_client.android.AndroidDriver;
import io.appium.java_client.android.AndroidElement;
import io.appium.java_client.remote.MobileCapabilityType;

public class base { 
    public static void main(String[] args) throws MalformedURLException, InterruptedException{
        File apk = new File("src");
        File fs = new File(apk,"betaWFM-v19_15thJune2017.apk");


        DesiredCapabilities cap = new DesiredCapabilities();
        cap.setCapability(MobileCapabilityType.DEVICE_NAME, "Test");
        cap.setCapability(MobileCapabilityType.NEW_COMMAND_TIMEOUT, "50");
        cap.setCapability(MobileCapabilityType.APP, fs.getAbsolutePath() );
        AndroidDriver<AndroidElement> driver= new AndroidDriver<>(new URL("http://127.0.0.1:4723/wd/hub"), cap); 
        driver.quit();
    }

}

但当我运行它时，在eclipse控制台中出现了以下错误：

Exception in thread "main" org.openqa.selenium.SessionNotCreatedException: A new session could not be created. (Original error: Command failed: Failed to install C:\Program Files (x86)\Appium\node_modules\appium\build\settings_apk\settings_apk-debug.apk: Failure [INSTALL_FAILED_ALREADY_EXISTS: Attempt to re-install io.appium.settings without first uninstalling.]

试图通过更改不同版本来解决，但无法解决。appium正在显示错误，但同时emulator正在显示已安装的应用程序。
有人有相同的问题吗？请提出解决方案

DesiredCapabilities=新的DesiredCapabilities（）；setCapability（CapabilityType.BROWSER_NAME，“”）；setCapability（“deviceName”、“Android”）；能力。设置能力（“设备”、“Android”）；能力。设置能力（“takesScreenshot”、“true”）；能力。设置能力（“平台名”、“Android”）；文件app=新文件（“app qa release.apk”）；setCapability（“app”，app.getAbsolutePath（））；驱动程序=新的AndroidDriver（新的URL（“http://127.0.0.1:4723/wd/hub(能力),；
