Android apk expansion file libs problems -

-

i'm following steps in dev guide implement google marketplace (play) expansion files setup:

http://developer.android.com/guide/market/expansion-files.html

i'm @ section "preparing use downloader library" i've added license lib, downloader lib , zip lib projects eclipse , libs main project. question compatibility. main project set minimum api 8 (android 2.2), yet market downloader library (found here: android-sdk-mac_x86/extras/google/market_apk_expansion) set android 4 , uses methods api 11. how work?

the link says:

note: default, downloader library requires api level 4, apk expansion zip library requires api level 5.

should looking older library?

i managed fix problem removing values-v9 folder in android-sdk/extras/google/market_apk_expansion/downloader_library project.

although library project built using android 4.0, seems work fine in android 2.2 project reference library.
