Distributing android app with custom keyboard

So I followed the tutorials and successfully created a system keyboard in Android Studio using the KMSample2. Now I can’t seem to find any information about how to distribute it successfully. It works great on my virtual android, but I need to send it to speakers to try out. Am I missing something obvious?


Here’s Google’s documentation on distributing an app: https://developer.android.com/studio/publish. It includes publishing through the Play Store as well as other methods. Generally, if you can get the .apk file onto the user’s device, that’s enough for them to start using it.
