Problems setting Push Notifications on Android with Parse -

i've been trying receive push notifications in android , had problems. me?

1) basic implementation works fine in android 4.0+, not in android 2.3, why?

2) i've implemented custom receiver tutorial explains, had inserted lines on androidmanifest tutorial showed (maintaining <service android:name="com.parse.pushservice" />) , i've removed line define defaultpushcallback, right? when send push dashboard, app receives , show default message, not passing in custom receiver, parse informations have sent.

use given manifest
