Hey, does it make any difference whether I set the content description of (for example) an `Icon`  to `null`  or `""` ?
Are they treated differently by e.g. screen readers?

I think yes. According to the doc:
&gt; Some visual elements are purely decorative and you might not want to communicate them to the user. When you set the `contentDescription` parameter to `null`, you indicate to the Android framework that this element does not have associated actions or state.
An empty string might be "read" by screen readers, or at least user will be able to select it with an empty description.
