title: Blocking android apps programmatically
body: <p>I tried to develop such an app, in the sense I want to lock all the applications in my device with a password whatever I want. But I didn't find any piece of code for the solution. So I developed one by myself and unfortunately it didn't succeed. I found many solutions for locking android devices but, didn't find one for locking an app. Will be glad if you suggest a solution.</p>
