In play Store developer console is there any options available to make all APK inactive. I want that user should not able to download app from play Store for a while. I don't want to unpublish the app.
I have not found any options in release management. Is it possible to make my app unavailable for some time? Don't want to delete app.
Let me make it clearer for you.
UNPUBLISHING app is not DELETING your app permanently. It is actually EXACTLY what you want. If you unpublish your app, it will be unavailable for new users to download your app, but still available for current users to use (play) or to get your app updated. When you want to make your app (apps) available again, just change its status from unpublished to published, then all users now can access it again. Moreover, by doing so, it will keep all of your apps' ratings, number of installs as before it was unpublished.
So if you want to make your app unavailable for some time (or make users unable to download your apps for some time), just make them unpublished.
Hope this helps!
