How to use Holo.Light theme, and fall back to 'Light' on pre-honeycomb devices?

I'd like to use the Holo.Light theme on devices that support it, and fall back to the regular Light theme on other devices.

At the moment, referencing Holo.Light works fine on 3.0+, but older APIs simply revert to the default 'dark' theme. Can I achieve what I want with with style inheritance?

You have to create a custom theme and save it in some directories to finally set this theme as the default one for the app

First, in values add a themes.xml like this:

<?xml version="1.0" encoding="utf-8"?>
<resources>
<style name="MyAppTheme" parent="@android:style/Theme.Light.NoTitleBar">
<!-- Any customizations for your app running on pre-3.0 devices here -->
</style>
</resources>

Then, create a directory with the name "values-v11" (Android 3.0+ ) in the res directory and put a themes.xml like this

<?xml version="1.0" encoding="utf-8"?>
<resources>
<style name="MyAppTheme" parent="@android:style/Theme.Holo.Light">
<!-- Any customizations for your app running on 3.0+ devices here -->
</style>
</resources>

Finally, create a directory with the name "values-v14" (Android 4.0+) in the res directory and create a themes.xml 

<?xml version="1.0" encoding="utf-8"?>
<resources>
<style name="MyAppTheme" parent="@android:style/Theme.DeviceDefault.Light.NoActionBar">
<!-- Any customizations for your app running on 4.0+ devices here -->
</style>
</resources>

With the DeviceDefault your app allways look perfect in any device of any company (HTC Samsung ... ) that add created custom themes for Android 4

EDIT: Samsung's interface (TouchWiz) dont respect this feature and the apps will be very ugly on Samsung's devices. Its better put Holo theme :(

Finally in your manifest.xml

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

You can also simply set the background to be white, and then go through and make all your other widgets black, like this:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
**android:background="#ffffff"
android:orientation="vertical" >


<TextView
android:id="@+id/tvText"
android:text="@string/text"
**android:textColor="#000000"
android:textSize="12dp" />
