IDE: Android Studio 1.1.0

ENV: Debugging on usb-connected phone using Android API v10.

I'm trying to use AppCompat to support Android API v8 and up. Compiles fine but crashes when the activity is drawn, saying:

lang.IllegalStateException: You need to use a Theme.AppCompat theme (or descendant) with this activity.

...however, in AndroidManifest.xml I have:

    <application
        android:name=".objects.PikCMS"
        android:allowBackup="true"
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/ThemeOverlay.AppCompat"
        >

Thank you & please forgive my frustration. I've been reading A LOT of related but unhelpful info. }8,(

Other Info

I do not want to force a specific theme.
I would like to avoid using different files for different API versions. However, I don't mind adding different versions of same property next to each other.
I had errors in styles.xml for items introduced in v11 (like "buttonBarStyle" & "showDividers"). After reading about the issue, I had thought AppCompat would "fill in the blanks" for pre11 APIs but (in my configuration) it isn't. These are currently all commented out -- until I find out how to use them with AppCompat. Similarly, I had problems with the layout files -- these problematic properties were deleted.
Activity class: Login.java extends :ActionBarActivity:. I'm also importing "android.support.v7.app.ActionBarActivity" but I'm not sure if I need all of it as I do not implicitly use the action bar (but I might in the future).

You need to replace your theme in the application tag of your manifest:

<application android:theme="@style/Theme.AppCompat">

ThemeOverlay should only be used with an actionBar with the new actionBarTheme attribute or with a toolbar. More informations here: https://chris.banes.me/2014/11/12/theme-vs-style/
