Usage of ?android:attr/ in backwards compatible apps

Question

I\'m trying to make my ICS (API level 15) app compatible with Gingerbread (API level 10), and I\'m getting InflateException Error inflating class

Answer 1

Please check android support v7 - appcompat project. It has many themes and attributes for backwards compatibility (attr/dividerHorizontal also)

To use v7 support you must import it as an Android lib project and reference to it from you project. It also contains v4 support so you may want to remove v4 support in your libs folder :) Good luck!!
