How to close down Android SDK emulator after running tests

Question

I am using Appium to run automated tests on an android emulator. I cannot seem to close the emulator down after the tests have finished. The research I have done seems to point to _driver.Quit(); closing the emulator but it remains running.

How do I close down the emulator after I have run a test?

Code:

[TestClass]
public class UnitTest
{
    AndroidDriver<AndroidElement> _driver;

    private static Uri testServerAddress = new Uri("http://127.0.01:4723/wd/hub");
    private static TimeSpan INIT_TIMEOUT_SEC = TimeSpan.FromSeconds(180);

    [TestInitialize]
    public void BeforeAll()
    {
        DesiredCapabilities cap = new DesiredCapabilities();

        cap.SetCapability("avd", "Device_01_Oreo_1440x2560");
        cap.SetCapability("deviceName", "Device 01 Oreo_1440x2560");
        cap.SetCapability("platformName", "Android");
        cap.SetCapability("platformVersion", "8.1.0");
        cap.SetCapability("udid", "emulator-5554");
        cap.SetCapability("appPackage", "appPackage");
        cap.SetCapability("appActivity", "appActivity");
        cap.SetCapability("unicodeKeyboard", true);
        cap.SetCapability("resetKeyboard", true);

        _driver = new AndroidDriver<AndroidElement>(testServerAddress, cap, INIT_TIMEOUT_SEC);
    }

    [TestMethod]
    public void Test_Open_Mobile_App()
    {
        _driver.FindElement(MobileBy.XPath("//android.widget.EditText[@index='0' and @password='false']")).SendKeys("EmailAddress");
        _driver.FindElement(MobileBy.XPath("//android.widget.EditText[@index='0' and @password='true']")).SendKeys("Password");
    }

    [TestCleanup]
    public void AfterAll()
    {
        _driver.CloseApp();
        _driver.Quit();
    }
}

Edit:

I have just tried to complete this task by killing the emulator process using the below:

Regex regex = new Regex(@"qemu-system.*");
foreach (Process p in Process.GetProcesses("."))
{
    if (regex.Match(p.ProcessName).Success)
    {
        p.Kill();
    }
}

This closes the android emulator down, however it also closes the Appium server down as well and therefore testing sequential devices wouldn't work.

So if there is a why to kill the emulator without killing the Appium server then this would also help my situation.

Appium does not let you terminate emulator instances. But you can use adb to shut them down. Incorporate something like below into your tear down code.

string cmdstr;
cmdstr="adb -s emulator-5554 emu kill"
System.Diagnostics.Process.Start("CMD.exe",cmdstr);
