Android revoke permissions from Code

Question

My request may seems strange, but I need to reset the permissions from the code. I ask the permissions like that :

if (ContextCompat.checkSelfPermission(getApplicationContext(),
            Manifest.permission.CAMERA)
            != PackageManager.PERMISSION_GRANTED) {

        ActivityCompat.requestPermissions(this,
                new String[]{Manifest.permission.CAMERA},
                MY_PERMISSIONS_REQUEST_CAMERA);
}

How can I revoke that permission once the user granted it?

您不能出于同样的原因不能授予它们 - 它们必须始终处于用户控制之下。
