Android app force closes when theme is set

Question

I'm just getting started with Android dev, done a few tutorials, now I'm working on a simple app. On both the emulator and my phone (Android 4.0.3 emulator, Android 4.1.1 Atrix HD) apps are displaying in what I think is Holo Light. I'd rather have it be Holo Dark, but when I add the following line to the application block in the Android Manifest file: android:theme="@android:style/Theme.Holo" the app compiles fine but force closes as soon as I open it.

What am I doing wrong? I'm sure it's something really simple, but as I said I'm new to this. Thanks in advance, y'all!

If you want to use a theme for all the activities of your application then you need to use

<application android:theme="@style/CustomTheme">

in AndroidManifest.xml.If you want a theme applied to just one Activity in your application, then add the android:theme attribute to the activity tag instead.So need to know what type you use in your application.However see these things which will clear you more..
