Issue with Scroll/Swipe in UiAutomator

My test app is in the second page of display and when use appViews.getChildByText(new UiSelector().className(android.widget.TextView.class.getName()),"<appName>",true) it is not finding the app. (My code works fine if the app is in the first page itself)

Below mentioned my code:

public void testFindAndRunND() throws UiObjectNotFoundException {
        getUiDevice().pressHome();
        UiObject allAppsButton = new UiObject(new UiSelector().description("Apps"));
        UiObject appsTab = new UiObject(new UiSelector().text("Apps"));

        appsTab.click(); 
        UiScrollable appViews =new UiScrollable(new UiSelector().className("android.view.View")
                .scrollable(true));

        //appViews.setAsHorizontalList();
        try{

        UiObject navigationDrawerApp = appViews.getChildByText(new UiSelector().className(android.widget.TextView.class.getName()), "QA FCU", true);
        navigationDrawerApp.clickAndWaitForNewWindow(3000);
        }
        catch(Exception e) {
            appViews.swipeRight(1);
            System.out.println("Not Exists^&********");
        }

        UiObject navigationDrawerValidation = new UiObject(new UiSelector().packageName("com.ifs.mobilebanking.fiid9901"));

        System.out.println("Verify the App is launched!!!!!!!");
        assertTrue("Unable to find the Application", navigationDrawerValidation.exists());
    }

Log is attaching below:

So my issues are:
1. Not scrolling and finding the app
2. If I use appViews.setAsHorizontalList();, i get "INSTRUMENTATION_STATUS: stack=java.lang.NoSuchMethodError: com.android.uiautomator.core.UiScrollable.setAsHorizontalList" Error..

Please help.

Here is the solution, everything works, much simpler too:

        getUiDevice().pressHome();
    UiObject allAppsButton = new UiObject(new UiSelector().description("Apps"));
    allAppsButton.clickAndWaitForNewWindow();
    UiObject appsTab = new UiObject(new UiSelector().text("Apps"));

    appsTab.click(); 
    UiObject appViews =new UiObject(new UiSelector().resourceId("com.sec.android.app.launcher:id/apps_grid"));

    UiObject navigationDrawerApp = new UiObject (new UiSelector().text("Contacts"));
    
    while (!navigationDrawerApp.exists()){
        appViews.swipeLeft(3);
    }
   
    navigationDrawerApp.clickAndWaitForNewWindow();

This will search for the wanted app trough all the screens you have until it finds it. Just edit the UiObject navigationDrawerApp = new UiObject (new UiSelector().text("Contacts")); with your app name and run the code
