端末のOSのバージョンをみる.
Log.d(TAG, "RELEASE : " + Build.VERSION.RELEASE);
Log.d(TAG, "SDK : " + Build.VERSION.SDK_INT);
RELEASE : 4.3.1
SDK : 18
「API-18」て「Gingerbread」だったけか?
などといつもググっているが.

いい暗記方法ねえかなと思いつつコードで吐く.
for (Field field : Build.VERSION_CODES.class.getDeclaredFields()) {
field.setAccessible(true);
Log.d(TAG, field.get(this) + " -> " + field.getName());
}

他の端末で.

その端末が知っているOSコードネーム群の最終がその端末のOSコードネームと想像.
Field[] fields = Build.VERSION_CODES.class.getDeclaredFields();
Log.d(TAG, "Name : " + fields[fields.length - 1].getName());
Name : LOLLIPOP_MR1
最終でないことはあり得るのか.
フツーに走査か.
