Spinner (Drop Down) problem


I am stuck on a point, i Need to select element from drop down which is exactly a spinner in Android, but unable to do it with tradition selenium way

First click on dropwodn spinner-> driver.findElement(By.id(“spItems”)).click();
Then wait for some time say 2sec->Thread.sleep(2000L);
dropdown list will popup & select an option -> driver.findElement(By.xpath("//*[@text=‘15 sec’]")).click();
