To change your application to a different built-in theme, just add this line under application tag in your app's manifest.xml file.

Example:

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

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

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

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

If you set style to DeviceDefault it will require min SDK version 14, but if you won't add a style, it will set to the device default anyway.

<uses-sdk
    android:minSdkVersion="14"/>

Actually you should define your styles in res values styles xml  I guess now you ve got the following configuration    lt style name  AppBaseTheme  parent  android Theme Holo Light   gt   lt style name  AppTheme  parent  AppBaseTheme   gt    so if you want to use Theme Black then change AppBaseTheme parent to android Theme Black or you could change app style directly in manifest file like this -  android theme   android style Theme Black   You must be lacking android namespace before style tag   You can read more about styles and themes here

If you are trying to reference an android style  you need to put  android   in there  android theme   android style Theme Black    If that doesn t solve it  you may need to edit your question with the full manifest file  so we can see more details
