The problem

I have created a AVD (named as deb) with android 7.0 API 24 and started (as a admin)- emulator is up and running Then started appium server (as a admin) and all good (Use Browser as Browser)

Now from Visual Studio selenium test the below code snippet trying to run (pretty basic - to lunch and go to a url)

[TestClass] public class DemoDevice { [TestMethod] public void AndriodTest() {

        try
        {
            DesiredCapabilities cap = new DesiredCapabilities();

           cap.SetCapability(MobileCapabilityType.BrowserName, "Browser");
            cap.SetCapability("device", "Android");
            cap.SetCapability(MobileCapabilityType.PlatformName, "Android");
            cap.SetCapability(MobileCapabilityType.DeviceName, "deb");
           // cap.SetCapability(MobileCapabilityType.AutomationName, "Appium");
            cap.SetCapability(MobileCapabilityType.PlatformVersion, "6.0");
            IWebDriver driver = new AndroidDriver<IWebElement>(new Uri("http://127.0.0.1:4723/wd/hub"), cap, TimeSpan.FromSeconds(180));
            driver.Navigate().GoToUrl("xyz");
        }
        catch (Exception e)
        {

            Console.WriteLine(e.ToString());
        }
    }

However getting error: Failed to start an Appium session, err was: Error: Command failed: C:\WINDOWS\system32\cmd.exe /s /c ““C:\Program Files (x86)\Android\android-sdk\platform-tools\adb.exe” -s emulator-5554 install “C:\Program Files (x86)\Appium\node_modules\appium\build\unlock_apk\unlock_apk-debug.apk””
