Grabbing Info From Another App

I’m looking for information on how/if you can grab information from another app in Android. For example, if I wanted to make an app that checked which song was being played in the Music app at the moment. Is this even possible? I Googled around and searched on here but didn’t find much.

Answer

You can communicate with other apps via intents. What communication is possible depends on what that particular actions that app made available.
