Getting error "A new session could not be created"

I am getting the following error, when running test script on Eclipse. Can anyone help to me?

org.openqa.selenium.SessionNotCreatedException: A new session could not be created. (Original error: Command failed: Failure [INSTALL_FAILED_VERSION_DOWNGRADE]
) (WARNING: The server did not provide any stacktrace information)

When Appium starts up, it installs apps on the device. If the app is already there and a higher version, it will fail. This is not likely your error unless you downgraded Appium. I suspect that you are running with Android N. If that's the case, you can find this discussion and the solution on this site.

Hi,
This is my code :
DesiredCapabilities capabilities = new DesiredCapabilities();
capabilities.setCapability("BROWSER_NAME", "Android Emulator");
capabilities.setCapability("VERSION", "7.0");
capabilities.setCapability("deviceName","Nexus_S_API_24");
capabilities.setCapability("platformName","Android");
capabilities.setCapability("appPackage", "com.android.calculator2");
capabilities.setCapability("appActivity","com.android.calculator2.Calculator");
driver= new AndroidDriver(new URL("http://192.168.2.22:4723/wd/hub"), capabilities);

Now i am getting error :
org.openqa.selenium.SessionNotCreatedException: A new session could not be created. (Original error: Could not find test emulator.) (WARNING: The server did not provide any stacktrace information)

Appium Error :

Thanks for any help.

I don't work with emulators, but these logs suggest to me that you need to start up the emulator, or if you expect Appium to start it up for you, it is not configured correctly.
