问题 I'm developing an Android application, I have to allow users to use camera to scan a QRCode. In each Android version (except > 6.0) i haven't problem, but in marshmallow I must enable manually the permission from "Settings -> App ->Permission" (it's strange because I have declared the camera permission in the manifest). I read the documentation dev-android website but i don't understand some things: if (ContextCompat.checkSelfPermission(thisActivity, Manifest.permission.READ_CONTACTS) !=

问题 I try to install a security manager from a Clojure program and am stuck short after a good start. This one works for me in Clojures simple REPL , in the Lein REPL, and in the Cider REPL in Emacs. It prevents the use of ( System/exit n ). (def SM (proxy [SecurityManager] [] (checkPermission [^java.security.Permission p] (when (.startsWith (.getName p) "exitVM") (throw (SecurityException.

问题 After reading a lot of SO topics about how to design a trial for the desktop software I still have some questions about trial for Web Application. I have a ASP.Net MVC Web Application and I'm offering a time limited trial for that. The applicaion will run in IIS > 7.0 so it has a very limited acces to the system and that is why there are not a lot of places for storing the information about the remaining trial.

For additions, modifications and deletions - the object permissions should be applied as normal. What is the best approach to

问题 I'm wondering about how is a signatureOrSystem permissions enforced on custom ROMs. Docs say: A permission that the system grants only to applications that are in the Android system image or that are signed with the same certificates as those in the system image. Where is this certificate?

问题 I have an ASP.NET app using Windows authentication, and I'm testing for the existence of a file on a remote server. I'm authenticating as MYDOMAIN\my.username - this works. The file is \MYSERVER\WebShare\example.txt. This file exists. I can open it from various hosts whilst logged in as MYDOMAIN\my.username. Under Windows Explorer, the effective permissions indicate that MYDOMAIN\my.username has full control of this file. If I attach a debugger and type $user in the watch window, I can see

问题 In the iOS client when you first run it you get a UIAlert asking for permission to grant access to send this person notifications. I'm wondering if its possible to first: Catch when this alert will fire (before it happens) Catch what response is given (cancel or ok) (after it happens) Is there such a way to get callbacks for the above two scenarios? Many thanks 回答1: On iOS 8 and later, implement the following method in your AppDelegate: - (void)application:(UIApplication *)application

问题 I have a view that I want to add to my django-restframework api that does not relate to any model.
