Updating apk only for specific version-Collection of common programming errors

Set:

In your Android Manifest

Edit:
Yes, that would need to have a different build. If you want t have only one apk and have certain features to only appear in Android Api 14+.

You can check at runtime like this (requires Api 4):

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.ICE_CREAM_SANDWICH){

If you are supporting Api below 4. Use this instead:

if(Integer.parseInt(android.os.Build.VERSION.SDK)>=14){

(Note: this is deprecated)
