During uninstall take them to a page where you very simply and sincerely ask them for feedback. Promise that you will read it and respond to it. Don’t require an email on that form though so they can answer anonymously if they want to.

Great suggestion but from what I've read there really isn't a way to detect uninstall events on Android.

Can you infer uninstalls from heuristics? If you're collecting activity metrics for app interactions and you get a complete dropoff for a given user, could you assume they have uninstalled? Even if they havent, checking in on decreased engagement might be an opportunity to get them before they uninstall.

Not sure what the timeframe is between a user trying it out and subsequently uninstalling, but if there is a bit of a time gap, the decreased interaction analytics could be a used as a leading indicator of pending uninstallation and used to trigger a win-back attempt?
