I've been stumped on this issue for a couple days now and I'm losing my hair. I scoured through pages upon pages of questions on-line and haven't found an answer so hoping for some help! I have an Android 4.0 app with a main activity that has a Navigation Drawer - and it works fine. Depending on the menu item chosen, I load either a Fragment or ListFragment. Again this works fine.
Now, I'm trying to provide support for Gingerbread using ActionbarSherlock. I updated my main activity and the code to use the ABS libraries, but I'm now getting an error only on my version 2.3 emulator! The updated code still works fine on 4.0+!
I get the following error: Binary XML file line #18: Error inflating class on my activity_main.xml
Maybe I've been staring at this too long but I can't understand why it works for ICS and up but not for Gingerbread! Does anyone know what I'm missing here?
Here is my code:
activity_main.xml:
<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/drawer_layout"

</android.support.v4.widget.DrawerLayout>
