Since I realized you *can* downgrade your apps (install lower version over actual (higher) version of app) using android feature "pm install -r -d file.apk" yesterday, I got time and wrote small and simple app which does everything for you. Just pick APK and click on Install APK. That's it!

App is now in Google Play Store!

did you read OP? Looks like you didn't. Yes, app shown "successfully installated" because if you use this app how you should, it works. And I don't except that users will do crazy experiments :D

With or without this app you can't install app which requires 4.1 on device with 4.0.

Is Google play suggesting to upgrade your downgraded app or it doesn't realize that app was downgraded?

Google Play will suggest upgrading. You essentially just installed an older version of the app in all terms.
You could achieve similar function by backing up your data, deleting the app, re-installing an older version, restoring your data. Obviously it would be longer, though. :)

    This app will let you install oldversion.apk without having to uninstall newversion.apk first.

    I am confused.
    So, I am asking since never tried:
    If I have old.apk, tap on it and choose to install via package installer (while new.apk is still installed) it will be DENIED?

    And if not, what is the purpose of this app?

    p.s. old.apk and new.apk refer to an old version and new version of the same app.

    @pyler,
    Thank you for this great app. It's worked on Android KitKat and Lollipop for me, but not Marshmallow.

    Has something changed in Marshmallow to make AppDowngrader not work?

    Have you ever felt that after an update your app or games start to have errors/ malfunctioning?

    it shows allow downgrade (debuggable packages only) Now what does a debuggable package mean :confused:
    Well that is definitely different and, I believe, explains this. I would suspect that debuggable package means that the app is built to be debugged by the developer. It is different from a released package which is what you usually get/install. Seems that Android, in its infinite wisdom and borderline mystical ways, has broken yet more long used mechanisms. Yet another reason to not use Android 8+, I guess. But then I still use mostly KitKat and will stay that way as long as possible. Sorry could not help here. But have at least learned something. Cheers
