Google play: "Item not found" error on installing application to android 2.x device

Google play: "Item not found" error on installing application to android
2.x device

My application uses module SDK Android 4.2.2 Platform, but in
AndroidManifest.xml I have
<uses-sdk android:minSdkVersion="8" android:targetSdkVersion="16" />
I am using google-play-services-lib in my application and Google Maps API V2.
I am using tester's account to login to Google Play and try to install my
apk (status - alpha) to android 2.3 device and get "Item not found error"
when clicking to "Upload from Google Play" button, but this app installs
well to android 4.x devices. On the other hand, I can install it on all
devices (android 2.x devices included) from USB or using
http://testflightapp.com.
My device included to supported devices list on Google Play, API level 8+.
Can anyone suggest any possible causes for this error? Many thanks.
