You can get it by calling Build.VERSION.SDK.

From 1.6 on, you should use Build.VERSION.SDK_INT instead
because Build.VERSION.SDK is deprecated.

07-15 15:19:04.680: E/AndroidRuntime(9733): java.lang.NoSuchMethodError: android.view.ViewTreeObserver.removeOnGlobalLayoutListener

There are two methods in ViewTreeObserver with almost the same name.

removeOnGlobalLayoutListener(ViewTreeObserver.OnGlobalLayoutListener victim)

(on then global) is a method that was added in API 16. It replaces

removeGlobalOnLayoutListener(ViewTreeObserver.OnGlobalLayoutListener victim)

(global then on) which has existed since API 1, but which is now deprecated. Compatibility libraries can cause confusion about these two methods; it can appear present at compile-time but fail subsequently.

This code thwarts the error:

try {
    thing.removeOnGlobalLayoutListener(victim);
} catch (NoSuchMethodError x) {
    thing.removeGlobalOnLayoutListener(victim);
}

So does this code:

if(Build.VERSION.SDK_INT < Build.VERSION_CODES.JELLY_BEAN) {
    thing.removeGlobalOnLayoutListener(victim);
} else {
    thing.removeOnGlobalLayoutListener(victim);
}

android - Set two buttons to same width regardless of screen size_ - Stack Overflow.pdf

weight 속성은, 남은 width에서 가져온다.

그래서 뷰의 width=0으로 고정해줘야만, 길이가 균등분배된다.

아니면 해당 뷰들의 width가 동일해도 좋다.
