Page Object - cannot use same page for iOS and Android

[jakubkopczyk]

Hi, my iOS test is running correctly, but when I try to start test for Android:

java.lang.IllegalArgumentException: Can not set io.appium.java_client.ios.IOSElement field pageObject.HomeScreenPage_new.MyFiles to io.appium.java_client.android.AndroidElement$$EnhancerByCGLIB$$97bbf586

my test class:

public class AndroidSanityNAS_testowy {

public AppiumDriver driver;

public  HomeScreenPage_new homeScreenPage;
private MyFiles_new myFiles;

@Before
public void setUp() throws IOException {
	driver = DeviceDriver.getInstance().getDriver();



}
@Test
public void test() throws InterruptedException {



	// ----------------- MY FILES ---------------------------
	homeScreenPage = new HomeScreenPage_new(driver);
	//myFiles = homeScreenPage.openAndroidMyFilesPage();

}

@After
public void tearDown() throws Exception {
if (null != driver) {
driver.quit();
}
}

}

Home Screen page:

public class HomeScreenPage_new extends AbstractPage_new {

@AndroidFindBy(xpath = "//android.widget.LinearLayout[1]/android.widget.FrameLayout[1]/android.widget.LinearLayout[1]/android.widget.FrameLayout[1]/android.support.v4.widget.DrawerLayout[1]/android.widget.RelativeLayout[1]/android.widget.RelativeLayout[1]/android.widget.ScrollView[1]/android.widget.GridLayout[1]/android.widget.RelativeLayout[1]/android.widget.LinearLayout[1]")
public WebElement A_MyFiles;
@iOSFindBy(name = "My Files")
public IOSElement MyFiles; 


public HomeScreenPage_new(AppiumDriver driver) {
	super(driver);
	loadPage();
}

public MyFiles_new openMyFilesPage(){
	waitForElement(MyFiles);
	MyFiles.click();
	return new MyFiles_new(driver);
}

public MyFiles_new openAndroidMyFilesPage(){
	waitForElement(A_MyFiles);
	A_MyFiles.click();
	return new MyFiles_new(driver);
}

Page Base:

public abstract class AbstractPage_new {
public AppiumDriver driver;

public AbstractPage_new(AppiumDriver driver) {
	  this.driver = DeviceDriver.getInstance().getDriver();
}

public void loadPage(){
		PageFactory.initElements(new AppiumFieldDecorator(driver), this);		
}

Thank You for any help

@jakubkopczyk , you can use same locator in same page, provided your app's UI is almost identical in IOS and Android. Let me give a code how you can use pageobject pattern for Android and IOS.

@AndroidFindBy(xpath = "//android.widget.LinearLayout[1]/android.widget.FrameLayout[1]/android.widget.LinearLayout[1]/android.widget.FrameLayout[1]/android.support.v4.widget.DrawerLayout[1]/android.widget.RelativeLayout[1]/android.widget.RelativeLayout[1]/android.widget.ScrollView[1]/android.widget.GridLayout[1]/android.widget.RelativeLayout[1]/android.widget.LinearLayout[1]")
@iOSFindBy(name = "My Files")
public MobileElement MyFiles;  

// Sample Method
 public void selectFile(){
        myFiles.click();
 }

Thanks,
Priyank Shah

I think I solved the problem. I've changed all IOSElement to MobileElement and no errors appeared
