Required SDK version

[j4velin]

What's the minimum SDK version required for the LiveWallpaperSource. .setBitmapSynchronous() call? I got crash reports from Android 2.3.7:

java.lang.NoSuchMethodError: android.content.SharedPreferences.getStringSet
at com.actionlauncher.api.LiveWallpaperSource.f(SourceFile:361)
at com.actionlauncher.api.LiveWallpaperSource.onCreate(SourceFile:112)

getStringSet() requires API 11, so it that enough?
