问题 I'm building an app that will listen for incoming SMS messages, perform some potentially long running operations and send back a reply if some conditions are met. I've got the listening part working using a BroadcastReceiver , but I'm not sure how/where to perform the potentially long running operations. The Android Developer Documentation states that After onReceive(), the system can kill the process at any time to reclaim memory, and in doing so, it terminates the spawned thread running in

问题 When I broadcast a message by the code below, the server on the host machine also receive the message, how can I prevent host machine to receive the message that it sends? Is it possible to change something on the code or would it be better to use something like if (strcmp(hostIP == IP_of_the_package) == 0) { <discard the msg>} ? the host machine gets IP from DHCP, how can I define hostIP as a variable and How can I extract IP addr of the packet ? void boardcast_msg(char *mess){ int sock;

问题 I want to resend received SMS_RECEIVED broadcast. I've find example here: http://blog.dev001.net/post/14085892020/android-generate-incoming-sms-from-within-your-app and make it by analogy: boolean received=false; private BroadcastReceiver broadcastReceiver = new BroadcastReceiver() { @Override public void onReceive(Context context, Intent intent) { if(intent.getAction().equals("android.provider.Telephony.SMS_RECEIVED")) { if(!received) { received=true; Bundle pudsBundle = intent.getExtras();

问题 I have following problem. I want to broadcast array of albums to another controller. Structure of my controllers : Parent - multimediaController, child - multimediaAlbumController. I am sending variable, but i cannot receive i, don't know why actually.. multimediaController.ts export class MultimediaController { $scope; static $inject = ['$scope']; constructor($scope){ this.$scope = $scope; } changeAlbum(){ this.$scope.$broadcast('prod', console.log("sending") ); } } multimediaAlbumController

问题 Right now my controller code looks like this: $scope.spAPI.load(id).then(function(result){ var deferred = $q.defer(); if(result !== undefined){ deferred.resolve($rootScope.$broadcast("onSpLoaded", result)); } return deferred.promise; }).then(function(success){ $scope.modalInstance = $modal.open({ ... }); }); I want the modal instance to be opened AFTER the broadcasts are processed. Is there a way to do this? Update: I was thinking about this problem backwards. I meant to do the broadcast

问题 I am getting the cursor value zero when i access it from Broadcast Receiver class , this is the code which i have use to access value from database public Cursor select_in(String num) { final Cursor cur= db.rawQuery("SELECT incoming FROM contactlist WHERE number=\""+num+"\"",null); return cur; } and this is how I call the function from my Broadcast Receiver Class and i have passed the context of OnReceive Method. openhelper=new OpenHelper(context); this.db=openhelper.getWritableDatabase();

问题 If my app runs once, service can start and request to server on background. But when app did not run before, service could not start. Is it possible starting service even that app have not runned before. Actually what I want to do is that phone can send request to server for once without even runned before. When request sended, it will be activation. Later request is not to require. 回答1: No, it isn't possible. When your app is getting installed for the first time OR was force-closed by the

问题 how to be notified (via some broadcast or intent) on a completion of a download initiated by user from web browser and other apps? (like email client, bluetooth, etc). I need this as I want to perform some action on each newly file downloaded by the user. It seems to me that this is possible as some antivirus apps do similar things. I tried to use broadcast receiver with intent filter set to DownloadManager.ACTION_DOWNLOAD_COMPLETE action, but this way I get notified only about downloads from
