The reason I checked in code that required you to build with later versions of Android is that you should always be building with the latest version of Android. For this particular case it does not cause any backward compatibility problems as the constants are inlined in the byte code so there no actually problem running this code on older versions of Android. All that happens is the attribute fails to be get/set.
