Automating the mobile browser on Android with Appium

I am writing a simple test to navigate to a website on a mobile browser, mostly to get an understanding of Appium. I am using an android emulator. My code looks like this:

import io.appium.java_client.android.AndroidDriver;
import io.appium.java_client.remote.MobileBrowserType;
import org.junit.Test;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.remote.DesiredCapabilities;
import java.net.URL;

public class DLMobileTest
{
    private WebDriver driver;

    @Test
    public void loadingSinglePageTest() throws Exception{
        DesiredCapabilities capabilities = new DesiredCapabilities();
        capabilities.setCapability("platformName", "Android");
        capabilities.setCapability("platformVersion", "5.0.1");
        capabilities.setCapability("deviceName", "Nexus 7");
        capabilities.setCapability("browserName", MobileBrowserType.BROWSER);
        driver = new AndroidDriver(new URL("http://ift.tt/1eWSHgW"), capabilities);
        driver.get("http://en.wikipedia.org");
        driver.quit();
    }
}

When I run the test, the emulator's browser briefly starts, but before it navigates to the Wikipedia site I'm aiming for, I get this:

org.openqa.selenium.SessionNotCreatedException: A new session could not be created. (Original error: Did not get session redirect from Chromedriver) (WARNING: The server did not provide any stacktrace information)

I'm not sure what my mistake is here. Any help is appreciated.
