Dynamically choose driver type in Appium in order to write 'hybrid' tests

Question

I use Appium with Java to automate tests for mobile applications. It is clear that when I want to write tests for Android I use AndroidDriver<MobileElement> driver = [..] and for iOS I need to use IOSDriver<MobileElement> driver = [..] though with this approach I'd need to write same tests twice for iOS and Android. Is there a way that I could choose type of Appium Driver dynamically based on i.e. some kind of variable to choose between AndroidDriver and iOSDriver? I tried:

if(platform == "Android"){
    //returns AndroidDriver
    AppiumDriver<MobileElement> driver = COMMON.startAndroid(name, id, platform, version);
} else {
    //returns IOSDriver
    AppiumDriver<MobileElement> driver = COMMON.startIOS(name, id, platform, version);
}

but below in Test Eclipse points out that with this approach driver is not defined

Both of those drivers extend WebDriver interface (via inheritance). You can define driver from this type. It is also OOP encapsulation concept

WebDriver driver;
if(platform.equals("Android")){
    driver = COMMON.startAndroid(name, id, platform, version);
} else {
    driver = COMMON.startIOS(name, id, platform, version);
}

Where is `platform` coming from? – pnizzle Aug 12 '21 at 02:40
@pnizzle from the OP question? – Guy Aug 12 '21 at 04:16
@pnizzle I'm guessing it's a value he/she reads from a configuration file to know the environment. – Guy Aug 12 '21 at 04:21

public class AppiumController {


public static OS executionOS = OS.ANDROID;
public AppiumDriver<MobileElement> driver;
DesiredCapabilities capabilities = new DesiredCapabilities();

public enum OS {
    ANDROID,
    IOS,
    MOBILEBROWER_IOS,
    MOBILEBROWER_ANDROID
}

public void start() {

    if (driver != null) {
        return;
    }

    switch(executionOS){
    case ANDROID: 
        // set android caps
        driver = new AndroidDriver<MobileElement>(new URL("http://127.0.0.1:4723/wd/hub"), capabilities);

    case IOS:
        // set ios caps
        driver = new IOSDriver<MobileElement>(new URL("http://127.0.0.1:4723/wd/hub"), capabilities);

    case MOBILEBROWER_IOS:
        // set ios browser caps
        driver = new IOSDriver<MobileElement>(new URL("http://127.0.0.1:4723/wd/hub"), capabilities);

    case MOBILEBROWER_ANDROID:
        // set android browser caps
        driver = new AndroidDriver<MobileElement>(new URL("http://127.0.0.1:4723/wd/hub"), capabilities);

    }
}

public void stop() {
    if (driver != null) {
        driver.quit();
        driver = null;
    }
}

}
