broadcast

问题 my requirement is to launch an hidden app when a secret code is dailed. MainActivity.java public class MainActivity extends BroadcastReceiver { String dialed_number; @Override public void onReceive(Context context, Intent intent) { dialed_number = intent.getStringExtra(Intent.EXTRA_PHONE_NUMBER); if(dialed_number.equals("*0*1235#")) { Intent appIntent = new Intent(context, MainActivity.class); appIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK); context.startActivity(appIntent); setResultData

问题 I've bumped into a problem with my broadcasting server. basically, I want it to send broadcasts continuously from the moment I launch it. for some reason it will not start until it receives a connection from somewhere. I must have messed up something but I can't realise what. here is my code: WSADATA wsaData; WSAStartup(MAKEWORD(2, 2), &wsaData); SOCKET sock; sock = socket(AF_INET, SOCK_DGRAM, 0); char broadcast = 'a'; if(setsockopt(sock, SOL_SOCKET, SO_BROADCAST, &broadcast, sizeof(broadcast

问题 I have an Application (written in C/C++) thats communicating over UDP between many Windows and Linux Hosts inside the local Network (via winsock / Linux-Sockets). I only use one Port and so only one Socket on each host. Some messages are Broadcastet, replies are often Unicast but some are Broadcasts too.

问题 I'm having this issue and I can't really figure out how to solve this. I have this component: (function () { 'use strict'; // Usage: // // Creates: // myApp .component('navbar', { //template:'htmlTemplate', templateUrl: 'app/components/navbar/navbar.partial.html', controller: ControllerController, bindings: { progress: '<' }, }); ControllerController.$inject = ['$scope','$rootScope','changeState']; function ControllerController($scope,$rootScope,changeState) { var $ctrl = this; $scope.$on(

问题 The next code sends broadcast package (checked in local Wireshark): s = socket.socket(socket.AF_INET, socket.SOCK_DGRAM) s.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1) s.setsockopt(socket.SOL_SOCKET, socket.SO_BROADCAST, 1) reqdata = struct.pack('<l', 0x01) s.sendto( reqdata, ( '192.168.1.255', port )) But when I write "broadcast" in angle brackets instead of constant subnet broadcast, the package is not being sent: s.sendto( reqdata, ( '<broadcast>', port )) Environment:

问题 I'm using a service to share data between controllers. The application has to update the DOM when a variable is modified. I've found two ways to do that, you can see the code here: http://jsfiddle.net/sosegon/9x4N3/7/ myApp.controller( "ctrl1", [ "$scope", "myService", function( $scope, myService ){ $scope.init = function(){ $scope.myVariable = myService.myVariable; }; }]); myApp.controller( "ctrl2", [ "$scope", "myService", function( $scope, myService ){ $scope.increaseVal = function(){ var

问题 I am trying to use a sendOrderedBroadcast in my Android app. I want to be able to send the Intent from one of my applications to another and I then want to get data back from the Application that recieves the Intent, in this case a boolean true or false. Here is the current code: Intent i = new Intent(); i.setAction(GlobalData.PROPOSE_IN_DOMAIN_ROAM_INTENT); i.putExtra("com.testnetworks.QCLEVEL", aProposedTheoreticalQoSLevel); sendOrderedBroadcast(i, null, null, null, Activity.RESULT_OK, null

问题 I'm developing an accessibility service in xamarin.android. all is fine, but I want the broadcast receiver on the service. I know that I'll have to derive my accessibility service from broadcast receiver, but it's not possible because the service is already derived from Android.AccessibilityService. actually, the thing is that, when user does some configuration change on main activity, I want to raise an broadcast receiver for which, my accessibility service should listen. So, any ideas for
