I actually want's to reach app changes in to user installed app.How this can possible.
1- My app is live on play store.
2- There are 30,000 of live users.
There is a bug in app and i resolved that bug now i don't want to upload new version of app on play store there is only small change so i don not update that version to play store now i don't want all users will update for small change updated build.
What i need to do for this if there is any tool to user device installed app that bug fixed which is i resolved.
I am not using Web-services for that change so data is not depend on web server. Is there any tool or any other way to reach users installed device that change for that all these changes reflect to user installed app??.
without any user authentication by playstore. or is there any way to reach these changes to user device.
No, like it or not, but there's no mechanism you can use to replace installed app or hot swap it portions on user's device other than reinstall.
In future release you could add ie push messages telling user to download the update from your server (but that would require enabled sideloading to have it installed).
