'Android - check for presence of another app
I'm working on an app that extends the functionality of another, existing app. I want to know what the easiest way is to determine, through code, whether the first app is installed, preferably by referencing it by com.whoever.whatever but almost any criteria would be helpful.

The recommended way is to check whether the other application publishes an Intent. Most Intent are not owned by a particular app, so, say, if you're looking for a program that publishes "sending mail" intent, the program that gets opened may be Gmail application or Yahoo Mail application, depending on the user's choice and what was installed in the system.

Starting Android 12, this requires android.permission.QUERY_ALL_PACKAGES permission, which Google Play may or may not allow you to have
