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

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    lt application      android theme   android style Theme Holo   gt    lt application      android theme   android style Theme Holo Light   gt    lt application      android theme   android style Theme Black   gt    lt application      android theme   android style Theme DeviceDefault   gt    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    lt uses-sdk     android minSdkVersion  14   gt

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
