Scroll is not working with android 2.0+

i am using phonegap/cordova 3.5.0.
in Android 4.1.2 i am able to scroll my content and side menu also.
if i am using same app with android 2.0+ than scroll is not working. its problem with ionic? or with phonegap?

my code:
<ion-content has-header="true" scroll="true" overflow-scroll="true"> </ion-content>

Androidmanifest:
<uses-sdk android:minSdkVersion="7" android:targetSdkVersion="19" />

Android 2.3 and lower are not officially supported by Ionic. Some functions might work, others might not.

This was announced on Github through issue: https://github.com/driftyco/ionic/issues/1663

ok thank you @coen_warmer
