title: Android TV switch HDMI input port programmatically
body: <p>I would like to ask you, experienced programmers, if there is a way to switch HDMI input port programmatically from an app installed directly on a TV Sony Bravia. Let's say, on app startup the TV switches it's input to i.e. HDMI3. Is there a common API in Android, or is the function vendor-specific?</p>
