why high API level added method AutoCompleteTextView.setText(CharSequence, boolean) run on low API level device work well

Question

doc:https://developer.android.com/reference/android/widget/AutoCompleteTextView.html#setText(java.lang.CharSequence, boolean)

in the doc said this method was Added in API level 17 but what device i had test:ZTE U880(2.2.2)API8, HuaWeiU8860(2.3.6) all work well

i want to known why?

Likely you're not calling that method but some overload in a superclass. Post your code. — laalto, Apr 27 '15 at 11:52
Another possibility is that the method had been in Android for some time, but was marked with `@hide` and therefore was excluded from the Android SDK. Not every device before API Level 17 will necessarily have that method, as device manufacturers can change anything that is not part of the Android SDK. — CommonsWare, Apr 27 '15 at 12:02
