Answer 1

You are using WEB locator for mobile. The correct XPath for this action would be following:

By.xpath("//*[@text='Sign in or']")

Answer 2

In Appium v1.5.3 - Android,For Clicking on Locator "Name" try with :

driver.findElementByAndroidUIAutomator("new UiSelector().text(\\"Locator name\\")").click();

For mentioned screenshot : driver.findElementByAndroidUIAutomator("new UiSelector().text(\\"Sign in or\\")").click();
