Unable to press numpad. Unable to scroll down

Hi, I am unable to press on numpad and also unable to scroll down when trying automation in java code. (Java, server side appium)

I have tried these after searching online but does not work for me.

Numpad

//wd.pressKey(new KeyEvent(AndroidKey.DIGIT_0));

//wd.findElement(MobileBy.AndroidUIAutomator("new UiSelector().text(\"1\")")).click();

//wd.pressKeyCode(8);

//wd.pressKey(new KeyEvent(AndroidKey.NUMPAD_1));

Scroll down

//String targetText = "Measurements";

//wd.findElementByAndroidUIAutomator("new UiScrollable(new UiSelector().scrollable(true).instance(0)).scrollIntoView(new UiSelector().textContains(\""+targetText+"\").instance(0))");));

Thank you.
