Tracking Android in-app subscription events with Firebase Analytics : <p>We're using Firebase Analytics to track our Android app.
We've connected it to our Google Play account in hopes to receive the automatic <code>in_app_purchase</code> events. What we later realized is that does not support in-app subscriptions: <a href="https://support.google.com/firebase/answer/6317485?hl=en">https://support.google.com/firebase/answer/6317485?hl=en</a></p>

<p>How do we track subscription revenue events?<br>
We thought about using the <code>ecommerce_purchase</code> event (<a href="https://support.google.com/firebase/answer/6317499?hl=en">https://support.google.com/firebase/answer/6317499?hl=en</a>) so we could track the ARPU, ARPPU and LTV of our users.  </p>

<p>The problem we are facing is dealing with subscription recurrence. Should we manually send this event each month/year and stop sending once the subscription is cancelled? It seems like a error-prone hack ...</p>

<p>Any other ideas?</p>

<p>Thanks!</p>
