Set capabilities in selenium
And set driver = new AndroidDriver(new URL("http://127.0.0.1:4723/wd/hub"), capabilities);
Once run selenium shown exception error as:
org.openqa.selenium.WebDriverException: An unknown server-side error occurred while processing the command. Original error: Command 'java -version' exited with code 2
In appium server shown as:

Here is the code:
DesiredCapabilities capabilities = new DesiredCapabilities();
String apkpath="apk/path";
File app=new File(apkpath);
capabilities.setCapability("app", app.getAbsolutePath());
capabilities.setCapability("deviceName","G2AXB711Y044HV6");
capabilities.setCapability(CapabilityType.VERSION, "6.0.1");
capabilities.setCapability("platformName","Android");
capabilities.setCapability("appPackage", "com.ABC");
