目标KitKat MR2（4.4.3）？

Question

I have a piece of code (actually a library I'm including) that only functions correctly using KitKat MR2 (4.4.3).

The other MR seem to have to their own API versions in Build.VERSION_CODES, but I can't find any way to target 4.4.3 and above using the SDK_INT. Should I just use the incremental String field and do a String comparison?

// the "easy" (wrong) way
if(Build.VERSION.SDK_INT >= BUILD.VERSION_CODES.KIT_KAT) { // but that includes 4.4, 4.4.1, and 4.4.2!

}

// the "hard" way
if(compareVersionCodes(BUILD.VERSION.RELEASE, "4.4.3") > 0) { // implement some comparison function for the version codes instead

}

Is targeting KIT_KAT acceptable -- meaning is this something like version 14 vs 15 where everyone automatically gets the higher version?

The API levels are for changes in binary compatibility -- stuff like new classes, new methods, etc. They aren't for bug fixes, other than to the extent such fixes break binary compatibility.

That's not awesome, but unless there's some way you can interrogate the Bluetooth LE APIs to see whether or not you're on a malfunctioning device, you may need to go this route. However, later this year, I'd set up the check algorithm to be more like:

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.WHATEVER_THEY_CALL_L ||
  (Build.VERSION.SDK_INT == Build.VERSION_CODES.KIT_KAT && getPatchLevel()>=3)) {
     // do your thing
}

where getPatchLevel() tries to use RELEASE to find the patch level and fails gracefully if RELEASE is not of the form XYZ This approach will handle both the 4.4.3/4.4.4 scenarios and whatever the numbering is for the next Android version.
