To use an image that varies depending on the theme, language, screen density or any combination of these variables, we need to add them to the same Image object.
Images are added to an existing image object using the New Image button:

newimagebutton

 

Once we have the new images added to the object, we need to which combination of Theme, Language and Density they apply.

Property Values
Theme Any theme found on the Knowledge Base
Language Any language found on the Knowledge Base
Density Unknown, ldpi, mdpi, hdpi, xhdpi, xxhdpi
