How can you lock apps being added

I don't know that you can...certainly, out-of-the-box, there's not an obvious way to do this that I've ever heard of.

Certainly, the Play Store (old Market) and Google don't want you to do this...

You can prevent (sort-of, byI turning off a switch/setting in the Settings app) apps from being installed from outside of the Play Store.

I'm betting there's a way to do this if you were rooted, but the solution I have in mind would be pretty invasive and wouldn't make the device very useful.

Maybe others know of a way...?

OP: by the way, I've edited your thread title from "apps" to "How can you lock apps being added".

 

Hmm, not sure of "locking" the ability to add (install?) apps either.

Unless the op is wondering how to stop (already installed) apps from automatically updating?...as I typed that, I'm not thinking so.

Perhaps more clarification is needed from the OP
